TY - JOUR T1 - Toxicity Test Using Life Stages of Champia parvula (Rhodophyta) AN - 19066772; 8910213 AB - A static-renewal, 11-day to 14-day toxicity test has been developed, using the life cycle of the marine red alga Champia parvula (C. Ag.) Harv., that measures the vegetative growth, formation of tetrasporangia (meiosis), and formation of cystocarps (sexual fusion). The procedure has been tested with silver, copper, cadmium, lead, and cyanide. The maximum acceptable toxicant concentration (MATC) ranges were calculated for vegetative growth of females and tetrasporophytes and for production of tetrasporangia based on statistically significant differences. The MATCs were determined for sexual reproduction using the presence or absence of cystocarps to measure significance which yielded MATC values similar to those determined by the other parameters. However, sexual reproduction was the most sensitive of the four end points examined because it dealt with absolute absence rather than statistical differences. The toxicity test with C. parvula is a relatively fast, simple, and inexpensive procedure for testing the effects of toxicants on growth and reproduction in macroalgae. All phases of the life cycle can be maintained in the laboratory (available year round) and can be exposed simultaneously. The results from tests with heavy metals and cyanide indicate that this procedure is comparable to the most sensitive marine animal chronic tests.

Six laboratories each conducted two 28-day flow-through tests, one with silver (as silver nitrate) as the toxicant and the other with the pesticide endosulfan. Muffled sand (from nonpolluted beaches) was used as sediment in the tests. The mean 28-day median lethal concentrations (LC50s) for the participating laboratories were 165 +or-52 micrograms/L for the tests with silver and 106 +or-24 for the test with endosulfan. The ratio of the highest to the lowest LC50 value was 2.23 for silver and 1.81 for endosulfan. The variability of the test for 28 days was about a factor of 2. There were no major problems with the test method or the biological aspects of the test. The details that caused some problems for participating laboratories were the chemical analysis of silver and the maintenance of the proper test concentrations, particularly of silver, in the experimental systems.

Significant portions of the DEHP losses from the water-column subsystem during the experiments were due to the complete breakdown of the parent compound to carbon dioxide (CO2). In the benthic subsystem, DEHP concentrations in the sediment were increased by more than 50 times the concentration in the water column during the winter and 250 times during the summer. Statistically significant reductions in the fluxes of ammonia (NH3) from the benthic subsystem were observed in microcosms receiving 100 micrograms of DEHP per liter during the summer. Concentrations of DEHP in selected bivalves ranged from 174 to 229,000 micrograms of DEHP per wet kilogram, depending upon the water column exposure concentrations and the season of the year. These results indicate that human exposure to DEHP could occur through ingestion of contaminated mollusks, crustaceans, and fish. Ecological effects were observed only in the sediment subsystem. An environmental assessment of DEHP based on a microcosm consisting of a water-column subsystem held at summer temperatures would have underestimated the potential hazards of this chemical. The only human exposure would have appeared to be indirect, perhaps through consumption of fish feeding on the water-column zooplankters, and the ecological effects would not have been observed.

A discussion of sampling gear recommended for use with the quadrat method is included. Treatment of plants for the purpose of identification and weight analysis is addressed, especially the problem of treating carbonate encrustations. Macrophytes are usually processed either while wet or after drying. Samples collected in the field can be identified, separated immediately, placed in plastic bags , and refrigerated or pressed and dried with a plant press for identificationand processing. Dry weight is determined by drying representative samples for 24hr or to a constant weight at 105 C. After samples have dried for a specified time period, they should cool for 1 hr in a desiccator before dry weights are determined. To ascertain the organic content (ash-free organic weight) of a sample or subsample, incinerate it in a muffle furnace of 550 C for 1 to 6 hr, depending on the amount of material to be ashed; cool the ashed sample in a desiccator; rewet it; and dry it for 24 hr at 105 C. Remove the ashed sample from the oven, place it in a desiccator, and allow it to cool for 1 hr; then weigh it to obtain ash content.

Water, fish, soil, sediments and air samples were analyzed. The highest levels ranged from 33,000 to 343,000 ppb, found in storage tanks and a contaminated horse arena. The highest levels in fish were found in suckers, ranging from 5 to 55 ng/kg. The highest levels found in fish were from specimens collected from the area where the highest sediment levels were observed. Although cleanup efforts are underway, investigations and monitoring of the problems are expected to continue for several years to come.

The facility manufactured hexachlorophene from tetrachlorobenzene with 2,4,5-trichlorophenol (TCP) produced as an intermediate. TCDD was formed as an unwanted trace contaminant of the TCP. A sampling survey of the Spring River, which drains the disposal sites, was conducted to determine if TCDD contamination had occurred. Levels detected in the upper reaches of the river tend to indicate that the contamination of the river has resulted from the waste management practices of the former company. Fish contamination above the point in the stream where pollution could enter the water could be explained by migration of the fishes. Two dams near Carthage, MO were expected to prevent sediment migration beyond that point and thus limit fish contamination to areas upstream of the dams. Contaminated fish were found for a distance of at least 21 miles beyond the dams, which were not physical barriers to fish movement in either direction. Bioconcentration of extremely low levels of TCDD from the aqueous phase may also explain the extent of the contamination. The detection limits were not sufficient to determine the sediment TCDD concentration in the river. TCDD was only found in sediments immediately downstream of the former manufacturing facility at 12 ng/kg.

AN - 14116591; 942538 AB - Adults of the bay scallop A. irradians were held in flowing seawater containing 5 or 10 mu g Cu/kg at ambient temperature and salinity. After eight weeks, scallops contained up to 91 and 310 mu g Cu/g dry weight, respectively, in the total soft parts. Copper uptake was linear over time. There was a significant inverse relation between dry weight and copper concentration ( mu g/g) in adductor muscle, visceral mass, and total soft tissue. A decrease in copper content occurred in the visceral mass and total soft parts during spawning in the control and 5 mu g Cu/kg treatments. There was no apparent decrease in copper concentration during spawning in any tissue of scallops from all three treatments. A. irradians is an excellent bio-indicator of copper, since accumulation was observed in the visceral mass at a seawater copper concentration of 1.8 mu g/kg.

Flow-through bioassays were used in this study of BBP with shiner perch (C. aggregata ). Using measured exposure concentrations, 96-hr LC sub(50)s averaged 0.51 mg/L. Effects on schooling behavior were found at 0.08 mg/L and coloration at 0.24 mg/L. Coupled with the behavioral changes, reduced brain levels of epinephrine found in surviving fish indicated that the mode of acute toxicity for BBP may be through its effects on the catecholamines of the central adrenergic nervous system.

AN - 14014239; 847790 AB - Using the transmission electron microscope, asbestos fibers have been assessed in kidney cortex of four groups of rats previously exposed to intermediate range feeding grade chrysotile asbestos. Newborn rats, from mothers gavaged with asbestos during pregnancy, were gavaged twice a week at the dose level of 50 mg/kg beginning at age day 7 until their natural death or sacrifice. Of the 20 rats comprising the four test groups, 17 were positive, average fibers recovery being 5.34 x 10 super(3)/mg dry weight. This study is consistent with the passage of chrysotile asbestos across the gastrointestinal wall.

AN - 13919663; 718009 AB - Widespread contamination of ground water by a variety of synthetic organic compounds has created a need for information about the biotransformation of these contaminants in aquifers and associated regions of the unsaturated subsurface. Selected organic pollutants were added aseptically to the samples at an initial concentration of 1 mg/liter water. No degradation of 1,1,1-trichloroethane, chloroform, or 1,1-dichloroethane was detected in any of the samples. Toluene and styrene was degraded slowly in samples from both positions at both sites. Chlorobenzene was degraded in samples from both positions at Pickett, but no degradation was detected in samples from Fort Polk. There was no detectable degradation of these three compounds in autoclaved samples. Tri- and tetrachloroethylene was degraded very slowly in some of the samples.

Survival of newly-hatched larvae and early juveniles was a sensitive measure. AC222,705 was about 20 times more toxic than permethrin. Predicted no-effect concentrations were between 0.66 and 1.4 ug per litre for permethrin and 0.03 and 0.07 ug per litre for AC222,705. The no-effect concentration for permethrin and snails was over 0.33 ug per litre. The residue concentrations for both pesticides increased with increased water concentration. Both permethrin and AC222,705 are toxic at low concentrations to early life stages of the fathead minnow.

All caused cell death although significant mortality was at levels greater than the EC50. Amdro did not kill S. costatum, Thalassiosira pseudonana, Isochrysis galblanc, Chlorella or Dunaliella tertiolecta, but was inhibitory to algae at low concentrations. Methodologically, lowest values for expression of toxicity should be considered as most closely approximating true toxicity, and these values should be calculated after only 2 days of exposure.

About 74 per cent of TQMS response factors for 53 pollutants were within plus or minus 15 per cent of values determined in the interlaboratory study. Their values were shown to be independent of the type of quadrupole scanned. The precision of the response factor determination was similar in the two cases (mean relative standard deviation 11.9 per cent).

Only PCB bioaccumulated above background concentrations, with fairly high levels being found in N. virens . Bioaccumulation was hindered by high organic content of sediment, although sediment concentration alone was not considered to reflect bioavailability. Exposure concentration resulting from sea disposal of contaminated sediments is related to the physical and chemical properties of the sediment and site-specific conditions.

Fish and sediment samples were collected from the headwaters to a distance of 96 miles downstream, during November and December 1981. Four laboratories were involved in the analysis of the samples, using different procedures for extraction with high resolution gas chromatography/low resolution mass spectrometry. TCDD was detected in fish from all the sampling locations, the highest concentration being 55 ng per kg. It was only found in sediments immediately downstream of the disused plant , at 12 ng per kg. Until further investigations have been carried out, the State authorities have imposed limits on the consumption of fish from the river.

The samples were analysed by electron capture gas chromatography and multiple ion detection gas chromatography-mass spectrometry, after Soxhlet extraction and Florisil chromatography. The chemicals most frequently found were p,p'-DDE , hexachlorobenzene and compounds of tech-chlordane . Many unidentified polychlorinated ion clusters were observed in the mass spectra of these samples in quantities insufficient to allow identification. Electron capture gas chromatography, even with high resolution capillary columns, is probably not sufficient alone to characterize environmental residues.

The discussion focuses on three particular process elements in the total environment, namely chemical change across the benthic boundary layer, the effect of sorption in direct photolysis, and volatilization. Sensitivity analyses were also performed to assess the magnitude of possible errors in the respective inputs. Satisfactory validation will depend on numerous tests of the performance of the model in predicting concentrations of chemicals in different environments, although comparison with the results obtained from the use of other models may give some guide to validity.

Maximal acceptable toxicant concentrations (MATC) ranges were determined for silver, copper, cadmium, lead and cyanide. The MATC values determined from the presence or absence of cystocarps were similar to those obtained from the other parameters. However, sexual reproduction was the most sensitive criteria. The results for cyanide were broadly in line with those obtained from other chronic bioassays using marine animals. JF - Aquatic Toxicology and Hazard Assessment: sixth symposium.

The selection of the test species and the nature of the dilution water might greatly influence the applicability of the results. Other factors, such as nutrition, acclimatization and generic selection, might also influence the accuracy of predictions based on laboratory data. The manner in which the laboratory test should be designed in order to provide meaningful results is discussed, depending on the objective of the test, ie to determine relative toxicities, to estimate safe levels, or to predict actual effects. Providing appropriate test parameters were chosen, it was considered that the response of laboratory organisms could provide a reasonable index of environmental behaviour and toxicity.

AN - 13622986; 513396 AB - Sensible heat flux data obtained from the U.S. Environmental Protection Agency's Regional Air Pollution Study in St. Louis, Missouri are presented and discussed. Large spatial variations exist in heat flux on both a land-use scale and the urban scale. Arguments based upon empirical data and sampling theory show that estimates of heat flux representative of an upwind fetch l sub(x) require a minimum observation height proportional to z super(3/4). The influence of advection on the magnitude of the heat flux is also explored for both the urban and sub-urban or land-use scales. The data clearly indicate that advection can strongly modulate and even dominate the vertical heat flux above surfaces in areas which maintain large horizontal temperature gradients. The advection contributions is positive for cold air advection and negative for warm air advection, and may result from either the urban heat island or land-use mesoscale features.

AN - 13594106; 492453 AB - A number of factors make the management of hazardous wastes complicated and expensive. The substances themselves are noxious and in some cases deadly, and that, combined with horrifying tales of past mismanagement of dump sites, has made it extremely difficult to overcome local opposition to the establishment of new disposal sites, which are urgently required in many countries. Many of the wastes are essentially non-degradable, and control of the sites must therefore be more-or-less permanent, which adds further to the costs. Contaminating wastes can reach the surrounding environment by a number of means--by surface run-off, by leaching into the groundwater, by direct contamination of soil--which makes the design and management of disposal sites more difficult and, again, more expensive. Finally the high cost of safe disposal tempts unscrupulous producers to cut corners, and unscrupulous disposal agents to opt for "midnight dumping." Consequently, monitoring the production of hazardous wastes and surveillance of its ultimate disposition have become significant additions to the total cost of disposal. The EPA has calculated that "administrative costs" account for about one-third of the total cost of hazardous waste disposal. JF - Ambio.

The possibility that there may be some disbenefits to the addition of these chemicals must be considered. It is essential to quantify any disbenefits and to minimize them while maximizing the beneficial side of the question. Three types of substances are examined: the disinfectants themselves (chlorine, ozone, chloramines, iodine or chlorine dioxide), the degradation products of those substances which are retained in water (chlorites, chlorates, hydrochlorites or iodates), and the chemical reaction products of those very potent chemically active substances with the other materials present in the water. Specific attention is directed toward the formation of trihalomethanes and their control. (Baker-IVI) JF - Environmental Health Perspectives Vol. 46, p 1-6, December, 1982. 1 Fig, 4 Tab.

A review of old as well as new literature shows that slow sand filters, rapid granular media filters, and DE filters are capable of removing bacteria, viruses, and cysts if designed and operated properly. Each of these filtration processes can be rendered ineffective by faulty design or by careless or improper operation. At slow sand filtration plants, controlling filtration rates and filtering to waste after filters are scraped are important aspects of filter operation. Effective coagulation and control of the filtered water 's turbidity at rapid rate filter plants will do much to assure that filtered water has a minimum number of microorganisms. The operator can control turbidity of the water more precisely by monitoring turbidity at each filter rather than at the clearwell. The particle size of diatomaceous earth (DE) selected for precoat and body feed influences removal of bacteria by DE filters. In order to remove viruses most efficiently by means of DE filtration, of some modification of either the filter aid or the raw water is needed. Raw water can be modified using cationic polymer. DE filtration is effective for removing cysts if an adequate precoat is used and the septum is kept very clean.

One channel was maintained at ambient seasonal Mississippi River water temperatures and the other at 10 C higher. Maximum water temperature reached 31.0 C in the ambient and 40.8 C in the heated channel. Elevated temperature seasonally altered macroinvertebrate abundance and life history in the channels. Few animals were found in the heated channel during the period of maximum water temperature. Most macroinvertebrate density and composition differences were confined to the channel riffles rather than the pools. Peak total density in the heated channel riffles occurred 3 or 4 weeks before the ambient channel. Total macroinvertebrate density was appreciably higher in the heated channel riffles during the winder and spring months and in the ambient channel riffles during the summer months. This seasonal alteration was due to composition differences of several identified taxa. Reproductive periods for one snail and one isopod species began about 2 and 3 months earlier respectively in the heated channel than in the ambient channel. No marked change occurred in the reproductive activities of an amphipod in the two channels. (Baker-FRC) JF - Water Research Vol 16, No 10, p 1465-1477, October, 1982. 8 fig, 3 Tab, 24 Ref.

Twenty-one chemicals of differing toxicity had been stored in the warehouse. Immediate damage to the groundwater and surface water was mitigated by the natural swales in the land and the hastily constructed retention dams, which contained the waste, and by the underlying layer of low-permeability blue clay. Contaminated water discharged through storm sewers to a nearby creek was temporarily contained by a bentonite-lined sand bag dam. This water was pumped into a quickly constructed 300,000 gal membrane-lined pit adjacent to the creek for storage and subsequent treatment with soda ash and activated carbon (1000 mg per liter dose). Because of the complex mixture of chemicals and difficulties with analysis, 72 hour static bioassays with fingerling perch were used to determine if the water had been sufficiently detoxified to return to the creek. Sludge produced from the flocculation process was disposed of in a landfill. Unburned products were placed in sealed drums and burned drums were placed in overpack drums for disposal in a hazardous waste landfill. The most heavily contaminated soil was removed to the landfill. The remainder of the debris-cleared site was treated with soda ash and powdered activated carbon to absorb toxic substances and encourage natural degradation processes.

Sampling was conducted on 6 cruises from April 1978 to August 1980. The highest percentage of positive stations (38% of stations positive for TC and 25% for FC) was located within 9 km of the disposal site center. The percentage of positive stations decreased with increasing distance from the center of the dumpsite. Positive samples were found as far as 37 km from the center. Sludge tended to travel in northeast and southwest directions and to settle in low spots. An area of at least 1190 sq km of ocean bottom was affected by the sludge dumping. The percentage of positive stations decreased with time. TC, FS, and amoebae were more persistent in sediments than FC. Therefore, FC can be considered an indicator of recent sludge deposition.

It uses mathematical programming to determine the levels of industrial pretreatment and municipal treatment which will meet the relevant environmental standards (sewer discharges, receiving water quality, and sludge quality) at minimum total cost. The problem is formulated as a nonlinear 0-1 integer program model. An implicit enumeration procedure that exploits the special structure of the problem is used for the solution. An analysis of heavy metals in the Kokomo, Indiana, treatment system showed that using uniform national standards for pretreatment was less cost-effective than using no minimum standards. Industrial sources accounted for 28% of total flow and 67-99% of Cd, Cr, Cu, Ni, and Zn entering the municipal plant. Cu was the critical receiving water parameter. If all Cu from the industrial sources were eliminated, other contributing sources would cause violation of the EPA limit 36% of the time using secondary municipal treatment and 22% of the time using tertiary municipal treatment. This method allows a city 's pretreatment requirements to be matched to local conditions. Using the desired receiving water quality as a goal, the treatment is distributed among the individual industries and the municipal plants on a cost-effective basis. In general, the industry with the largest pollutant input is required to treat to a higher level. The problem of differences in treatment levels may cause complaints of inequity, which must be resolved.

Pilot-scale diffused air aeration studies, pilot-scale granulated carbon and granulated synthetic resin columns, and boiling studies are described. When aeration was used to remove trichloroethylene, it and other solvents were removed. Adsorption was most effective when preceded by aeration. Boiling can remove solvents at point of use, but at least five minutes of vigorous boiling is needed. Preliminary cost estimates varied significantly with treatment process and contaminants. Estimates can only be made with thorough organic analysis and site-specific performance data. Data on the characteristics of the following compounds are given: trichloroethylene, tetrachchloroethylene, 1,1 ,1-trichloroethylene, cis-1,2-dichloroethylene, carbon tetrachloride, and 1,2-dichloroethane.

Excellent agreement was obtained between observed and calculated turbidities for 1977 (the year used to determine the coefficients) and 1976, 1978, and 1979. Results show that turbidity is directly related to wave action and the resulting bottom stress. Turbidity is not closely related to wind magnitude or wind direction. Sediments from the Maumee River significantly contribute to the amount of entrainable sediment near the intake. Sediment loadings, highest in spring, show a highly seasonal variation. High turbidity is produced by the transport of suspended solids from the Maumee River to the intake. There is a reasonable equality between turbidity in NTU units and suspended sediment concentrations in units of mg per liter.

' About 75 papers are noted which concern new isolation and enumeration procedures. Many of these are comparisons of different procedures such as membrane filter, most probable number and its variations, plating, and direct count using coliforms and other fecal bacteria. Selective procedures are given for microorganisms such as Legionella pneumophila, Yersinia, Campylobacter, Vibrio, Aeromonas, Klebsiella, Salmonella, and Listeria. There is great interest in commercially available diagnostic kits, multitest systems, and automated computerized methods for bacterial identification, as evidenced by about 25 publications on testing and comparison of these systems. Sampling considerations include special problems of collecting specimens from boats, under ice cover, in stratified waters, from aquifers, in streams, wastewaters, boiler water, industrial effluents, sediments, at bathing beaches, and in deep waters. New approaches to rapid methods for bacterial enumeration are discussed. Examples are radiometric, serological, electrochemical, enzyme, chromatographic, and chemiluminescent methods. Bacteria are used in bioassays for toxic or mutagenic substances, for example, Nitrobacter for assessing wastewater toxicity, effects of dyes on bacterial action, and improvements and development of the Ames Salmonella test. Quality control schemes are described, using control cultures and statistical methods. Several possible sources of error are mentioned, such as stacking plates, and nonuniform cooling rates. Health hazards to laboratory workers include infections from pathogens used in the Ames test and typhoid fever from the very infectious Salmonella typhi, sometimes used in testing disinfectants.

Analytical standards were extracted with dichloromethane and dried by passage through a glass wool/sodium sulfate column. After drying, the column was rinsed with hexane; the rinse was combined with the extracts, and the whole sample was reduced to about 0.5 milliliters under a stream of dry nitrogen before reconstitution to 5 milliliters by the addition of hexane. The extracts were refrigerated until LC/MS analysis, when they were reduced to 1.0 milliliters under a stream of liquid nitrogen. Average recoveries were 57% for aldicarb, 110% for aldicarb sulfone, and 101% for aldicarb sulfoxide. MS compares favorably with other detectors in terms of sensitivity, and the selectivity of the MS and minimum cleanup time required are added advantages.

Compared with 1973, the total flow reaching treatment plants has increased 36% to 95,594 million cu m per day, BOD removal has increased 13% to 76.4%, solids removal has increased 11% to 79.6%, and dry sludge has increased 58% to 23 ,763 metric tons per day. The population served by treatment plants in 1980 was 156.7 million (70% of the total population), 8.5% more than in 1976. Those served by secondary treatment or better increased 25.3% since 1976 to 119.4 million (53% of population). Since 1976 the number of secondary plants has increased by 58.8% to 6852 and the number of plants that do not discharge, by 36.1%; to 1361. During 1973 to 1979 $20 billion in federal, state, and local funds and $6.3 billion in non-government funds were spent for capital improvements. By 1985 it is expected that flows reaching treatment plants will reach 28,000 mgd, an increase of 14%, and BOD removal and suspended solids removal efficiencies will have increased to 82.6% and 83.4%, respectively.

Among the particles which must be removed by filtration are asbestos, bacteria, clay, protozoan cysts, fine rock particles, and viruses. In DE filtration small quantities of DE as a filter aid are continuously added to the feed. Filtration takes place on a permeable septum precoated with a thin layer of DE. Coagulants are rarely used. DE filtration may be done under pressure or vacuum. Removal of Giardia cysts can reach 99.99%; asbestos fibers, 99.99%; and plankton, 100%. Turbidities of 0.10 NTU are attainable. The granular media filtration process, most commonly used in the U.S., usually includes coagulation, flocculation, sedimentation, and filtration. If raw water quality is good, sedimentation and sometimes flocculation may be omitted. Continuous monitoring of turbidity can quickly detect early filter breakthrough. Filters should be backwashed before turbidity reaches the 1 NTU level. Giardia cysts and asbestos fibers removal is effective when turbidities do not exceed 0.1 NTU. Slow sand filtration, a biological process developed in the 19th century, effectively removes bacteria. The system is most suitable for small communities because capital costs are low and large areas of land are required for the filter beds.

The studies feature occurrence surveys, treatability studies to assess individual toxic removal mechanisms and pilot-scale plant removal studies using wastewater spiked with selected priority pollutants (metals and organics). In the plant removal studies, the treatment plant performance on spiked wastewater is usually compared to the performance of identical treatment on the unspiked raw wastewater. The assessments employ costly analyses (GC/MS and atomic adsorption methods) for the selected toxic substances in the various process streams and sludges of treatment plants. A biomonitoring approach to assess health and ecosystem effects is also being evaluated to supplement the specific toxic substance removal data. From the studies to date, conventional primary-activated sludge treatment is generally effective in removing toxic substances, typically achieving better than 90% removal of organics and from 60-80% removal of the metals. However, a number of the toxic substances were found in the plant final effluents at concentrations which, based upon EPA recommended water quality criteria may present a possible environmental hazard.

The study covers 158 facilities in SIC major group 3100 Leather and Leather products, and specifically subgroup SIC 3111, leather tanning and finishing. Effluent limitations guidelines are set forth for the degree of effluent reduction attainable through the application of the best practicable control technology currently available (BPT), and the best conventional technology pollutant control technology (BCT) which must be achieved by existing point sources by July 1, 1984. Standards of performance for new sources (NSPS) set forth the degree of effluent reduction that is achievable through the applications of the best available demonstrated control technology, processes, operating methods or other alternatives. Pretreatment standards for existing and new sources (PSES and PSNS) set forth the degree of effluent reduction that must be achieved in order to prevent the discharge of pollutants that pass through, interfere with, or are otherwise incompatible with the operations of POTWs. Supporting data, rationale, and methods for development of the effluent limitation guidelines and standards are contained in this document.

Information was collected to provide the Tacoma-Pierce County Health Department with chemical data needed to begin a preliminary assessment of any health risk possibly faced by persons eating fish and crabs from Commencement Bay and adjacent waters. Sampling was conducted from July 1981 to January 1982. Eighty-six non-salmonid fish and six Dungeness crabs were collected from popular sport fishing locations in the vicinity of Commencement Bay and from a remote reference area, Discovery Bay. Muscle tissue from these specimens was chemically analyzed for selected metals and organic compounds (EPA priority pollutants). Specimens from the Commencement Bay area generally had higher contaminant levels than did the specimens collected from Discovery Bay. The pollutant concentrations in the fish and crabs varied considerably, depending on the species and their location. The highest concentrations of polychlorinated biphenyls (PCB's) and pesticides were measured in fish from the Hylebos Waterway, while the highest total metal concentrations measured in fish were found in flatfish from the Point Defiance Dock. Regardless of where the crabs were collected, they contained total metal concentrations several times higher than the highest levels detected in fish. The mercury, PCB, and DDT concentrations measured were always well below the tolerance or action levels estabalished by U.S. Food and Drug Administration (FDA). However, few specific guidelines are available to assist in the direct assessment of the potential toxicity of many individual chemicals detected. The existing guidelines also do not address possible combinations of chemicals and metabolites. No attempt was made in this report to conduct an overall assessment based on these data.

Financing structures for water utilities are traditionally such that a reduction in demand may necessitate an increase in rates charged to the consumer, to avoid shortfalls in utility income for debt service and fixed operating expenses. In addition, a number of ' beneficiaries ' of the water supply system, such as those who enjoy fire protection, or those whose land is more attractive for development due to the availability of water, but who are not major consumptive users of water, tend not to bear the potential increased unit costs associated with user demand reduction. The problem can be considered as one of spatial economics - water system customers of certain classes, located in portions of the service area, subsidize other beneficiaries of the system in other classes and areas. The impact of demand reduction, coupled with the existing financial and revenue structure, can be expected to exacerbate the existing subsidizations of water system beneficiaries. The Drinking Water Research Division of USEPA has developed a systematic approach, organized as a set of computer programs, to assist analysts in examining problems of spatial economics and physical behavior of water distribution systems. The approach, known as the Water Supply Simulation Model (WSSM), consists of a data base describing the physical, economic, and spatial characteristics of the distribution system and program modules to: create and maintain the data base; display it graphically; perform hydraulic network, time of travel, and other physical analyses; and to perform economic allocations to develop spatial cost of service. The system is general-purpose in nature, and can easily be modified to suit the needs of a specific situation. Through combination of concepts of spatial analysis, spatial economics, data base management, and analytical mathematical modeling, the WSSM provides a powerful tool for examining the consequence of alternative policies related to water supply utilities. The structure of the WSSM, and sample applications, are described.

Secchi disc transparency, total depth, and field observations were recorded by 141 volunteers monitoring 87 lakes. Lakes ranged in transparency from 137.9 inches (Arbor in DuPage County) to 7.3 inches (Royal in Calhoun County). The clearest lakes were generally in the northwestern and southern part of the state; the most turbid, in the central and southcentral regions. Average transparencies of less than 4 ft (minimum recommended for bathing beaches) were reported in 63 of the 87 lakes. About 1/3 of the lakes had average values less than 2 ft, indicating use impairment problems. None of the monitored lakes were classified oligotrophic, 9 were mesotrophic, and the remainder were eutrophic. A primer of basic information on Illinois lakes for the layman is given. This includes origin, shape, hydrology, ecosystems, thermal stratification, succession and eutrophication, pollution, and water quality control measures.

The primary objectives of this project are to identify the most viable agricultural non-point source control strategy, demonstrate its effectiveness, develop a methodology to identify land causing water quality problems and to determine the appropriate RMS's. The physical, biological, and chemical characteristics of the Blue Creek watershed were studied since May, 1980. A comprehensive monitoring network for the entire Blue Creek Watershed was established by IEPA to document the basic hydrological, meterological, and water quality factors of the project area during 1980. The duration, timing and quantity of NPS pollutants were evaluated to determine land management effects on the water quality/quantity budget. Methods used for field and laboratory procedures are those accepted for agricultural related hydrology research. Analytical techniques are documented, but not detailed. By October 1, 1981, 70% of the soil loss reduction goal had been achieved, and erosion had been reduced by 16,495 tons/year. Precipitation was 17.5% above normal, with variability of streamflow attributed primarily to the precipitation patterns and land cover. High flows were measured from February through June while lower flows were measured during July and August. The rainfall-runoff ratio ranged from 4.7% to 80.1% during July and averaged 41.4% for Water Year 1981. Water samples were collected at seven stations in the Blue Creek Watershed during Phase II of the project, with three types of stations located within the watershed: watershed stations (A,B,C) sub-basin D and field stations (E,F,J).

The recent amendment of the municipal wastewater treatment construction grants program focuses efforts on achieving results through reduced federal involvement and increased state delegation. A problem of inefficiency of wastewater treatment plants in region II seems to result from a non-compliance factor. A diagnostic review of treatment plants in the region has been started, involving four phases: preliminary investigation, on-site inspection of every aspect of plant operations, identification of problems and drawing conclusions, and solution and implementation planning with both short and long term corrective actions. EPA has also begun a campaign of collecting overdue bills, which amount to millions of dollars nationally. Use of funds on actions which work directly toward improving water quality is stressed. Ocean dumping of sludge is being investigated. (Baker-FRC) JF - Clearwaters Vol 12, No 1, p 7, March, 1982. AU - Dewling, R T AD - Environmental Protection Agency New York.

Serious symptoms of acidification have been documented in lakes of New York 's Adirondack Mountains, far removed from any industrial activity. While precipitation is most acidic in the northeast US, the geographic extent of the problem encompasses the southeast and portions of the midwest and far west. A growing body of evidence suggests that acid precipitation adversely affects public welfare through loss of fish and other aquatic life, increased leaching of nutrient cations from the soil, possible reductions in crop and forest productivity, and the release of heavy metals or nutrients from rocks, soils and lake and stream bottom sediments. Research on aspects of acid rain is reviewed. The sensitivity of surface water bodies to acid precipitation was evaluated, and historical changes in surface waters were documented.

Several studies have shown that significant numbers of multiple drug-resistant coliforms occur in rivers, bays, bathing beaches, and coastal canals. This is a source of considerable concern, since bacteria carrying transmissible R-factors are capable of transferring antibiotic resistance to antibiotic-sensitive bacteria, raising the potential for transfer of antibiotic resistance to pathogenic species. The effect of ultraviolet (UV) light disinfection on antibiotic resistant coliforms in municipal wastewater effluents was investigated. Total coliforms and total coliforms resistant to streptomycin, tetracycline, or chloramphenicol were isolated from filtered activated sludge effluents before and after UV light irradiation. The wastewater effluent was effectively disinfected by the UV irradiation, but the percentage of the total surviving coliform population resistant to tetracycline or chloramphenicol was significantly higher than the percentage of the total coliform population resistant to those antibiotics prior to treatment. UV treatment did not affect the percentages of coliform resistant to streptomycin. Analysis of the multiple drug resistance patterns of 300 total coliform isolates revealed that 82% were resistant to two or more antibiotics. In addition, 46% of these isolates were capable of transferring antibiotic resistance to a sensitive strain of Escherichia coli.

Sources of contaminants may be natural (humic and fulvic acids), the treatment process (trihalomethanes), point sources (priority pollutants), and nonpoint sources (pesticides). In most cases it is necessary to quantify compounds at the ppb or ppt range. Basic steps in analysis are extraction, concentration, separation, detection and quantitation. Gas chromatography-mass spectrometry and gas chromatography with conventional detectors are useful for low to medium molecular weight compounds. Cost per sample is $100-1500 and $30-500, respectively. High performance liquid chromatography can be used to determine compositions of low to high molecular weight compounds at a cost of $50-500 per sample. Systems for measuring total organic carbon and total organic halogens are available for $9000-15,000 and $9000, respectively. The importance of a quality assurance program is emphasized. The bibliography lists many books, trade publications, and government documents which provide detailed information.

Damage from salt loading occurs mostly in the Lower Colorado River Basin. Remedies for salinity problems include collecting and treating or disposal of natural point sources. Cost-effective technologies for dealing with salt loadings due to irrigated agriculture include improved irrigation and on-farm management practices to reduce deep percoaltion loss and the building of canals and laterals to channel salt losses. Development of coal and oil shale resources in the Upper Colorado River Basin will necessitate use of river water, allowing even less downstream flow for salt dilution.

It is expected that slight changes will be made during the review process. In developing the upcoming metal finishing regulations, the EPA has responded to problem areas, and made modifications which will make these regulations clearer and more reasonable. The major changes include the use of concentration basis versus production; greater coverage of total plant process wastewater under one regulation; consideration of removal which occurs at the municipal wastewater treatment facility; and separation of studies of job shops and printed circuit board manufacturers to account for economic impact. Each of these major changes is discussed in detail, followed by a presentation of the staff recommendations for the regulation. Removal rates, and daily maximum and 30-day maximum effluent concentrations for appropriate metals are listed.

This paper presents an overview of guidelines applicable to reuse of municipal wastewaters as mandated by recent federal law, and the U.S. Environmental Protection Agency 's extension of this mandate into federal guidance for management of the EPA Construction Grants program. Historically, the earliest legislation did nothing to encourage wastewater reuse. The Federal Water Pollution Control Act of 1956 was, however, the turning point. It contained a modest construction grants program which included support for research and development of new technologies. Recent research and demonstration projects are rapidly advancing the knowledge 68 reuse of wastewaters in agriculture, silviculture and aquaculture. Finally, the EPA has issued a series of guidance documents to encourage proven and developing wastewater management technologies which include reuse.

In 1969, the Council on Environmental Quality (CEQ) was formed; and in 1970, the U.S. Environmental Protection Agency (EPA). Both began work on the PCB problem. CEQ was the catalyst in the formation of a federal interagency task force to coordinate the federal PCB effort. In May 1972 the task force issued a report concluding that PCB contamination was ubiquitous and represented an unquantified but undisputable hazard, and that the use of PCB should be restricted to essential applications that involve minimal direct human exposure. Once this report was issued, programs aimed at correcting the PCB problem were begun. In 1971 Monsanto, the sole domestic commercial producer of PCB, voluntarily restricted sales of PCB to ' closed-system uses, ' thereby limiting sales to manufacturers of transformers and capacitors. Monsanto also introduced what it felt was a less toxic PCB mixture, Aroclor 1016. The EPA recommended raising water quality standards to reduce PCB levels to less than 0.01 ppb. In February 1973 the Organization for European Community Development (OECD) issued a directive that recommended limiting the worldwide use of PCB. EPA designated PCB as toxic substances and set a national effluent standard pursuant to Section 307(a) of the Federal Water Pollution Control Act Amendments of 1972 (PL 92-500). In 1973 the Food and Drug Administration (FDA) published regulations limiting the use of PCB in food and feed facilities and establishing temporary tolerances for PCB levels in many food and feed items. In February 1977 EPA banned PCB discharges into waterways by capacitor and transformer manufacturers, and finally in 1976 the Toxic Substances Control Act (TSCA) (PL 94-469) was passed by Congress, requiring regulation of PCB.

The basic managerial framework of Section 311 of the Clean Water Act is carried over to the Superfund program. EPA 's Emergency Response team presently directs a national alerting system for rapid dissemination of information on personal safety and hazard assessment to protect public health and personnel in environmental emergency situations. This is made possible through the NIH/EPA OHM-TADS oil and Hazardous Materials Technical Assistance Data Systems computerized chemical information system. EPA is currently developing an integrated health and safety program for EPA employees involved in hazardous substance cleanup, which may serve as a model for the Interagency Working Group. The major components of this program include: development of generic safety plans for hazardous waste site investigations and spill response which can be tailored to particular incidents; a system of audits to ensure compliance with health and safety requirements; provisions for accident reporting; training requirements; general emergency procedures; criteria for medical surveillance of workers, including pre-assignment health assessments, periodic health assessments, maintenance of employee medical records for at least 30 yr; and rules concerning personnel practices such as wearing of protective clothing. The Superfund bill established a new agency within the Public Health Service, the agency for Toxic Substances and Disease Registry. The appropriate division of responsibilities and coordination among federal, state, and local government agencies with respect to health studies and registries must be resolved. The nature and scope of federal responsibilitiy for ensuring adequate health care for victims of chemical contamination, and for training of physicians and public health professionals capable of dealing with hazardous waste incidents at the non-federal level must also be defined.

No single model is uniquely suited for a specific problem and some problems require more than one model for their solution. Several planning and analysis models were applied to the flooding problem caused by poor urban drainage in the Four Mile Run watershed. The STORM model was used to develop flood frequency curves, while the WATERSHED model was used to simulate surface flow from individual subcatchments, pipes, and open channels. These simulations helped to ensure that future modifications in the watershed will not lead to future flooding problems. Planning and analysis models were used to reduce pollution load to the Sandusky River from combined sewer overflows in Bucyrus, Ohio (the Stormwater Management Model or SWMM) and to design and analyze urban drainage systems in Edmonton , Alberta (the HYMO model, STORM, and SWMM). The use of a planning and analysis model to extend a limited data set in a study done by the Illinois State Water Survey in Bloomington-Normal, Illinois is described. Here the QUAL-ILLUDAS model was used to assess the effects of storm runoff, point sources, and combined sewer overflows to establish the variability of constituent levels over time to aid in the planning of urban stormwater facilities. The EXTRAN (Extended Transport) block of the SWMM program was used to optimize the construction of relief sewers in the Borough of East York, Toronto. Three planning and analysis models, SEMSTORM, RUNOFF, and TRANSPORT, were used to assess the nonpoint source contribution to the pollution of Dorchester Bay from combined sewer overflows in Boston, Massachusetts. Other model applications open to the creative planner are considered. (See also W87-09096) (Geiger-PTT) JF - Urban Stormwater Hydrology, American Geophysical Union, Washington DC.

Microbial effects testing may provide a sensitive method for detecting potential environmental perturbations. The use of microbial effects tests might have alerted the Life Sciences Corporation to the problems that resulted from releasing what was probably Kepone, into the Hopewell, Virginia biological treatment plant. Microbial effects tests for measuring decomposition of organic substances have provided sensitive and rapid methods for detecting the effects of smelter emissions on microbial processes in soils. Some representative microbial effects tests provide measurements of growth, product formation, and substrate oxidation, reduction or disappearance. Microbial effects tests may provide sensitive, reproducible, and cost-effective methods for detecting the effects of toxic substances on microorganisms and their activities.

The chief priority in the water supply program is provision of safe drinking water by using highest quality water sources and protecting these sources from degradation. Most New England surface water sources are relatively free of pollution by municipal and industrial wastewater discharges.

AN - 15568318; 416543 AB - This report is based on regression analysis of one year of visibility and particle-monitoring data collected in the southwestern U.S. Average extinction coefficients for 23 sight paths were determined from contrast measurements made by teleradiometers at seven locations. Coarse and fine mass concentration data were collected with two-stage particle samplers at six locations. Overall, the coarse and fine particle data explain more than 75% of the variations in the particle extinction coefficient. Regression coefficients indicate measured coarse particles are one-half to one-third as efficient as fine particles in their contribution to extinction on a per unit mass basis. On the average, coarse particles contribute from 30% to as much as 80% of the particle-related optical extinction for this data set. JF - J. AIR POLLUT. CONTROL ASSOC.

AN - 15557260; 402346 AB - Two integrated sampling and analysis methods for determining NO sub(x) emissions in electric utility plants were developed and field tested. The collection systems consist of: a 4.0% potassium permanganate-2.0% sodium hydroxide solution in restricted-orifice impingers, and a 5 degree molecular sieve in midget impingers. Sample analysis is accomplished by a colorimetric or ion-chromatographic procedure with the alkaline-permanganate method and by a colorimetric procedure with the molecular sieve method. The alkaline-permanganate method gives excellent agreement with the EPA reference method, Method 7, for NO sub(x) measurements. The molecular sieve method shows a significant negative bias relative to Method 7. It is anticipated that the permanganate methods will be proposed as alternates to Method 7, for NO sub(x) determinations, under the EPA New Source Performance Standards. JF - J. AIR POLLUT.

AN - 15555553; 409915 AB - Three simplistic models are developed for evaluating the transport of organic pollutants through soil to ground water. The models consider mobility and first-order degradation. The first calculates linear sorption/desorption of the pollutant and first-order degradation without considering dispersion. The second is similar to the first but also considers dispersion. The third considers nonlinear sorption following a Freundlich equation and first-order degradation but does not consider dispersion. The models are compared to field data for the pesticides aldicarb and DDT. The models projected a lower mobility for DDT than was observed in the field.

AN - 15555270; 402562 AB - In recent years, considerable attention has focused on the concept of "human exposure" to environmental pollutants, but different investigators seem to have developed different definitions of this concept and used different approaches for estimating it. This paper reviews a number of "exposure" studies in a single environmental medium-air pollution-to see how others have defined this concept in the literature. Many previous investigators unfortunately calculate "exposures" by relying on data from fixed air monitoring stations, and they assume that people are located in the same place, usually their residential address, throughout a 24-h period.

Serial blood, urine, and fecal samples were taken from each animal for 3 weeks. A three-compartment, open system model with parallel first-order elimination into the urine and feces was developed to simulate mirex pharmacokinetics after either iv or po administration. All data were simulated on an analog-digital hybrid computer by simultaneous integration of the differential equations describing the model.

During the study opacities ranging from 2% to 57% were measured. The high opacities were usually obtained by reducing particulate control efficiencies. The data were compared with the acceptable standards of plus or minus 7.5% opacity deviation between observer and transmissometer used to certify observers of training plumes.

AN - 15552958; 402708 AB - This paper discusses the economics, advantages, potential aplications, and status and future research needs of porous pavements. Porous pavements are an available storm water management technique which can be used on parking lots and low volume roadways in order to reduce both storm water runoff volume and pollution. In addition, ground water recharge is enhanced. Also, cost reductions result due to elimination of curbs, drains, and small sized storm sewers. Porous asphalt pavements consist of a relatively thin course of open graded asphalt mix over a deep base of large size crushed stones. Water can be stored in the crushed stone base until it can percolate into the subbase or drain laterally. Other porous pavement types include concrete lattice blocks and a porous concrete mix.

AN - 15552748; 402635 AB - A new sampler has been developed which is a possible replacement for the flow controlled Hi-vol sampler. Field and laboratory tests have shown that the Bell-vol sampler offers advantages over the traditional Hi-vol for many applications. This sampler uses a passive pneumatic flow controller to regulate the flow rate rather than the blower speed control commonly used for AC/DC motors. This new control coupled with an AC inductive motor and a cyclone blower provides effective control of flow rates from 100 through 1500 L/min. Thus, the reliability of an inductive motor plus the absence of brushes are incorporated into the design. JF - J. AIR POLLUT. CONTROL ASSOC. AU - Bell, J P AD - Inorg. Pollut. Anal.

AN - 15548495; 412825 AB - Errors in pH measurement of 0.1-0.2 units can be propagate large errors in the predicted aqueous speciation. When accurate on-site analyses are impossible to obtain, changes in pH and alkalinity between the time of sampling and after transport to a laboratory must be minimized in many sampling programs. Several container and cap combinations were evaluated for their ability to preserve the pH and alkalinity of test waters that were out of equilibrium with atmospheric carbon dioxide over time periods representative of mail or other surface transport. Provided that no air bubbles were present when the sample bottle was filled and sealed, polyvinyl chloride bottles with caps having a conical polyethylene insert yielded the most satisfactory results. High density linear polyethylene bottles were also generally satisfactory. Cap design was observed to be very important. Guidelines for analysis and preservation are given, and if followed, laboratory measurements can be reliably substituted for field measurements in many instances.

AN - 15542967; 384784 AB - It has been previously demonstrated that carrier waves of 50 and 147 MHz, when sinusoidally amplitude modulated at 16 Hz (ELF), can cause enhanced efflux of radiolabeled calcium ion from chick brain tissue in vitro. This phenomenon occurs only when the samples are exposed to specific intensity ranges of the carrier wave. Unmodulated carrier waves do not affect the ion efflux. Since the ELF signal must be demodulated from the carrier wave to be effective, a study of the efflux enhancement due to the ELF signal may lead to an identification of the site of demodulation, as well as provide clues to the underlying mechanism. The authors report here that 16-Hz sinusoidal fields in the absence of a carrier wave can alter the efflux rate of calcium ions. The results show a frequency-dependent, field-induced enhancement of calcium-ion efflux within the ranges 5 to 7.5 V/m and 35 to 50 V/m (peak-to-peak incident field in air) with no enhancement within the ranges 1 to 2, 10 to 30, and 60 to 70 V/m.

AN - 15542281; 394985 AB - Concentrations of sulfur dioxide from model estimates and monitoring stations are available from previously conducted point source studies at seven power plant monitoring networks. Data for two to seven monitoring stations for either one or two years are available for examination of extreme values (specifically second highest, once-a-year) for 3 and 24 h averaging times. These data total 43 monitoring station-yeast. Stations whose elevations relative to the plant stack height result in the CRSTER model's marginal applicability, show overestimated concentrations by the same model. After removing those data which exceed a specific elevation criteria (6 of the 43 data sets), the comparison of second highest 3 and 24 h model estimates with measurements, although containing considerable scatter, reveals no significant bias toward over or under calculation. For 24 h period 68% are within a factor of two; for 3 h period 84% are within a factor of two. JF - Atmospheric Environment AU - Turner, D B AU - Irwin, J S AD - Meteorol. and Assess.

AN - 15541442; 418571 AB - Macroinvertebrates were sampled monthly from December 1976 to September 1977 in two 520 m long outdoor experimental channels. One channel was maintained at ambient seasonal Mississippi River water temperatures and the other 10 degree C higher. Maximum water temperature reached 31.0 degree C in the ambient and 40.8 degree C in th heated channel. Elevated temperature seasonally altered macroinvertebrate abundance and life history in the channels. Few animals were found in the heated channel during the period of maximum water temperature. Peak total density in the heated channel riffles occurred 3 or 4 weeks before the ambient channel. Total macroinvertebrate density was appreciably higher in the heated channel riffles during the winter and spring months and in the ambient channel riffles during the summer months. This seasonal alteration was due to composition differences of several identified taxa. JF - Water Research AU - Arthur, J W AU - Zischke, JA AU - Ericksen, G L AD - Monticello Ecol. Res.

AN - 15541347; 415929 AB - The thermal response of a human in the near-zone of an antenna was determined by numerical procedures. The approach taken was to modify the heat transfer equations for man in air to account for thermal loading due to the energy absorbed from the radiating antenna. The absorbed power density distribution in the human body was determined by considering the body and antenna to be a coupled system in which the resulting system of equations were solved by moment method procedures. This information was then analyzed by a thermal response model consisting of a series of transient conduction equations with internal heat generation due to metabolism, internal convective heat transfer due to blood flow, external interaction by convection and radiation, and cooling of the skin by sweating and evaporation. Internal heating patterns were calculated for two cases: a human in the near-zone of a quarter-wave monopoleand a half-wave dipole operating at 45 and 200 MHz, respectively. It was fund that negligible heating occurred for antennas with input power levels of less than 50 W. JF - IEEE Transactions on Microwave Theory and Techniques AU - Spiegel, R J AD - Bioeng.

AN - 15540109; 416456 AB - The body of information presented in this paper is directed towards engineers in the field of environmental sciences involved in measuring and/or evaluating the emissions from a variety of diesel engines or vehicles. This paper summarizes recent data obtained by EPA on identification and quantification of different emissions from a variety of diesel engines. Extensive work has been done comparing emissions from some light duty diesel and gasoline passenger cars. The work on the diesel vehicles was expanded to include tests with five different diesel fuels to determine how fuel composition affects emissions. This work showed that use of a poorer quality fuel frequently made emissions worse. The investigation of fuel composition continued with a project in which specific fuel parameters were systematically varied to determine their effect on emissions. EPA is presently testing a variety of fuels derived from coal and oil shale to determine their effects on emissions. JF - J. AIR POLLUT. CONTROL ASSOC.

AN - 15536444; 380881 AB - Adult rats anesthesized with pentobarbital and injected intravenously with a mixture of ( super(14)C)sucrose and ( super(3)H)inulin were exposed for 30 min to an environment at an ambient temperature of 22, 30, or 40 degree C, or were exposed at 22 degree C to 2450-MHz CW microwave radiation at power densities of 0, 10, 20, or 30 mW/cm super(2). A significant increase in permeation was found for sucrose but not for inulin. A correction factor was then derived from the warm-air experiments to correct for the increase in permeation of the brain associated with change in body temperature. This correction factor was applied to the data for the irradiated animals. After correcting the data for thermal effects of the microwave radiation, no significant increase in permeation was found.

AN - 15535559; 373004 AB - Past work on analyzing ground-source diffusion data in terms of surface-layer similarity theory is reviewed; these analyses assume that sigma sub(z)/L or h/L is a function of u*x square root uL. It is argued that an alternative scaling, h*/L versus x/L, is nearly as universal in that it is very weakly influenced by surface roughness, except for a modest influence in the free convective case, the advantage of this scaling is that it eliminates the need to reassess uu- as vertical diffusion progresses. The Prairie Grass data set is adjusted for the difference in source and sampling heights, and is plotted with this scaling.

AN - 15532331; 389119 AB - This study examined the fate of Prudhoe Bay crude oil in nearshore sediments of the Beaufort Sea, in situ, with emphasis on the role of microorganisms in the weathering process. The results indicate that oil is degraded in Arctic sediments very slowly; only after 1 year's exposure was biodegradation evident. Several factors probably contributed to the slow rate of microbial weathering. Abiotic weathering of the oil was also slow, with limited loss of low molecular weight aliphatic and aromatic hydrocarbons during 2 years' exposure. Significant features of the overall weathering process were: lack of initial loss of low molecular weight compounds; aliphatic compounds were not preferentially degraded over aromatic compounds and C sub(17) and lower molecular weight normal alkanes were preferentially degraded over higher molecular weight alkanes. The results of this study indicate that hydrocarbons will persist relatively unaltered for several years if Beaufort Sea sediments are contaminated with petroleum. JF - Marine environmental research.

AN - 15529077; 374870 AB - The EPA Office of Air Quality Planning and Standards (OAQPS) is developing a new Aerometric Information Reporting System (AIRS) to consolidate and improve the support now provided by a number of existing software systems, including the National Emissions Data System (NEDS), Storage and Retrieval of Aerometric Data (SAROAD), Hazardous and Trace Emissions System (HATREMS), and Comprehensive Data Handling System (CDHS). AIRS is being designed to provide an interactive, user-oriented data base management system which facilitates the collection, validation, storage, retrieval, and analysis of emissions and air quality data. This paper presents anticipated engineering design concepts for the source emissions portion of the AIRS data base. Data base structure and data element definition, new data editing and screening capabilities, and proposed reporting and data analysis capabilities are identified. The principal benefits to system users in terms of improved procedures for input, retrieval, and analysis of data are highlighted. JF - J. AIR POLLUT. CONTROL ASSOC.

AN - 15527160; 356317 AB - Viruses of animals, plants, and bacteria abound in sewage and receiving waters. Their ecological impact has, for the most part, gone unheeded except as it relates to viruses from human sources. Viruses present at levels infective to man have been recovered from waters used for recreational or drinking purposes. Their presence in a water environment virtually always denotes prior contamination by domestic wastes. Neither conventional sewage treatment processes nor the discharge to land or water of sludges produced by these processes achieve full viral control. Many environmental virologists advocate the setting of permissible virus limits for those recreational and potable waters dominated by wasterwater effluents. The initiation of regulatory pressure to restrict virus discharges into these water environments has been instituted in Montgomery County, Maryland, and in the states of California and Arizona.

AN - 15526425; 356058 AB - Regulatory agencies deal with risks that cannot be controlled by the marketplace. Pesticide regulation involves a balancing of risks and benefits. The precision of risk assessment must be consistent with other inputs. Options are finite: continue use, restrict use, ban use. Decisions must withstand legal tests and strike a balance between timeliness and certainty. Regulatory decisions approach moral decisions. The assessment of chlorobenzilate demonstrates the multidimensional process. Because of uncertainties and data gaps, public policy choices must be factored into the assessment. The process can be improved by being more systematic and by dealing more explicitly with uncertainties. JF - AM. STAT.

The authors of the study theorized that CFC's released in the lower atmosphere would not be destroyed by any natural process, but would slowly migrate to the stratosphere. There they would be broken down by ultraviolet radiation, releasing chlorine atoms that would in turn react with, and destroy, ozone molecules. JF - AM. STAT.

AN - 15526321; 355607 AB - Tri-o-cresyl phosphate (TOCP) and O-ethyl O-(4-cyanophenyl) phenylphosphonothioate (cyanofenphos, Surecide) were found to be delayed neurotoxicants. They were administered to chickens by gavage at 100 and 30 mg/kg multiplied by d for 15 d, respectively. In CD-1 mice neither TOCP nor cyanophenphos induced any of the usually recognized clinical symptoms of neuropathy when administered daily by gavage at 262 or 31.25 mg/kg multiplied by d for 30 d, respectively. In the chickens, TOCP and cyanofenphos produced about 98 and 90% in vivo inhibition of brain neurotoxic esterase (NTE) activity. In the mice, 24 h after the last daily dose, TOCP and cyanofenphos produced only about 50 and 40% in vivo inhibition of the brain NTE activity. Parathion (O,O-diethyl O-(4-nitrophenyl) phosphorothioate), at 2 or 6.75 mg/kg multiplied by d for 15 or 30 d, did not induce neuropathy in either chicken or mice and produced no significant in vivo inhibition of brain NTE activity at the end of the dosing regimen. The specific activity of NTE in control chicken brain crude homogenate was much higher than that in mouse brain homogenate.

AN - 15524881; 355642 AB - Whole-body evaporative heat loss was measured as whole-body evaporative water loss in mice during a 90-min exposure to 2450-MHz microwave radiation at an ambient temperature of 20 degree C and in non-exposed mice maintained at ambient temperatures of 20, 25, 30, 33, and 35 degree C. A specific absorption rate of microwave radiation in excess of 29 W/Kg was required to produce an increase in heat loss. For absorption rates ranging from 29 to 44 W/Kg, the mouse dissipated 65% of the total absorbed heat by water evaporation; the remainder was dissipated passively. The data collected in the mouse may be extrapolated to larger species, such as man, but only by an exponential relationship. Using this relationship, it was shown that a threshold specific absorption rate of 29 W/Kg in a 0.033-Kg mouse was equivalent to approximately 0.25 W/Kg in a 70-Kg human. JF - J. MICROWAVE POWER.

AN - 15524319; 356448 AB - Benomyl, a systemic fungicide whose molecular basis of action is inhibition of tubulin polymerization, was administered during organogenesis via the dietary and gavage routes to pregnant Wistar rats, and via the gavage route to pregnant CD-1 mice. Benomyl was fetotoxic and teratogenic in both species via the po route of administration, producing a broad spectrum of malformations at a dose of 62.5 mg/kg/day in the rat and 100 mg/kg/day in the mouse. Via the dietary route of administration, benomyl produced fetotoxicity, but no teratogenic effects. The fetotoxic potential of benomyl from dietary exposure was approximately an order of magnitude less effective than from gavage exposure. Benomyl did not affect postnatal growth, viability, or locomotor activity at subteratogenic doses. The most sensitive indicator of perinatal exposure to benomyl via the po route of administration was a permanent reduction in testes and accessory sex gland weight noted in male offspring of dams receiving 31.2 mg/kg/day benomyl during gestation and lactation. No effects on any parameters were evident in rats receiving 15.6 mg/kg/day by po gavage. The relevance of the two routes of administration for risk extrapolation is discussed.

AN - 15524285; 356436 AB - Groups of male CBA/J mice were injected with Salmonella typhimurium lipopolysaccharide (LPS) and irradiaated with 2450 MHz (CW) microwaves. The 50% lethal dose (LD sub(50)) of LPS was determined for mice irradiated at 30, 20, 10 and 5 mW/cm super(2) immediately folowing injection. The average specific absorption rate was approximately 0.6 W/kg per 1 mW/cm super(2) incident power. An equal number of animals served as sham-irradiated controls for each power density. The mice were placed individually in small containers and were maintained at 22 degree C and 50% relative humidity during a 2 hour irradiation period. Following irradiation the mice were returned to their home cages and were observed for 48 hr. A significant decrease in the LPS dose required to kill 50% of the mice was observed at power densities of 20 and 30 mW/cm super(2). High ambient temperature (37 degree C) also potentiated the lethal effect of endotoxin. Microwave irradiation prior to LPS injection, however, did not affect the lethal action of LPS.

The average specific absorption rate (SAR) was 16.5 W/Kg. Two experiments were performed under these conditions. At 3 and 6 weeks of age the mice were assessed for development of the primary immune response to sheep erythrocytes, in vitro mitogen-stimulated lymphocyte proliferation, and natural killer (NK) cell activity. No consistent significance in the primary immune response, in the mitogen response, or in the NK cell activity was observed between irradiated and sham-irradiated mice. JF - J. MICROWAVE POWER.

AN - 15523641; 355338 AB - There is considerable need to harmonize not only the internationally-recognized test methods but also the fundamental processes and conditions by which test data are developed. As more countries pass legislation to control chemical substances, governmental authorities will receive substantial quantities of test data from national and international laboratories for assessment of the potential hazard that these chemicals may pose to human health and the environment. In order to confidently rely upon these test data, laboratory testing should be conducted under procedures and conditions which will ensure the quality and integrity of the test data. If individual countries can rely upon internationally-developed test data, duplicative testing can be avoided, thereby reducing the burdens of cost and time imposed upon international chemical trade. Reciprocal acceptance of test data internationally could contribute substantially to international trade and avoid possible trade barriers. JF - IN "QUAL. ASSURANCE OF TOXICOLOG. DATA".

AN - 15523013; 355408 AB - This overview represents much of the discussion and summarizes many of the concerns emerging from the recent APCA Specialty Conference, "In-Situ Air Quality Monitoring from Moving Platforms." Users of mobile air quality monitoring systems have been hampered in their attempts to generate dependable data because of a lack of suitable instrumentation. Most equipment used in mobile systems was designed for laboratory or stationary monitoring applications and cannot cope well with the harsh environment encountered in aircraft or other mobile platforms. Only through innovative modifications have investigators been able to utilize off-the-shelf equipment. The technology exists, however, for manufacturers to build a much higher quality product if only a market incentive could be created. This paper outlines problem areas which need to be addressed in the production of reliable "mobile quality" instrumentation, and suggests some market incentives. JF - J. AIR POLLUT. CONTROL ASSOC.

A tracer, sulfur hexafluoride, was released from the forest and collected downwind in order to define the dispersive characteristics of the atmosphere. Simultaneously, alpha -pinene concentrations were measured both upwind and downwind of the forest. A Gaussian plume dispersion algorithm incorporating hydrocarbon lose due to O sub(3) and OH reaction was used to estimate alpha -pinene emissions.

AN - 15521990; 355472 AB - The relationship between chlorophyll A, total phosphorus, secchi disk depth, and trophic state were examined using data on U.S. lakes collected by U.S. EPA's, national Eutrophication Survey. By comparing predicted secchi disk depths with observed summer secchi disk depths in 757 lakes, it was determined that in many lakes nonchlorophyll related light attenuation is important in controlling the amount of chlorophyll A produced per unit of total phosphorus. Rankings of 44 lakes by 18 different trophic state measurements and single and multivariable indices were compared with rankings provided by mean summer ambient total phosphorus and chlorophyll A. The trophic state measurements and indices were much more successful in ranking the lakes against total phosphorus than chlorophyll A, indicating that there are differences in the relative trophic rankings of many of the lakes depending upon whether primary nutrients or biological manifestations are used as the ranking mechanism.

AN - 15518075; 358963 AB - In a recent article in Transportation Research, Daganoz (1981) described a model of gap acceptance that permits the mean of the gap acceptance function to vary among drivers and permits the duration of the shortest acceptable gap for each driver to vary among gaps. The model contains several constant parameters whose values must be estimated statistically from observations of drivers' behavior. The results of numerical experiments reported by Daganzo (1981) suggested that the values of the parameters cannot be estimated by the method of maximum likelihood, which is the most obvious estimation technique, and Daganzo proposed using a sequential estimation method instead. The sequential method appeared to yield reasonable numerical results. In this paper, it is shown that subject to certain reasonable assumptions concerning the true parameter values and the probability distribution of gap durations, the maximum likelihood method does, in fact, yield consistent estimates of the parameters of Daganzo's model, whereas the sequential method does not. Hence, maximum likelihood is the better estimation method for this model. JF - TRANSPORT. RES.

AN - 15512142; 326925 AB - Fresh water lake sediment removal is usually undertaken to deepen a lake and increase its volume to enhance fish production, to remove nutrient rich sediment, to remove toxic or hazardous material, or to reduce the abundance of rooted aquatic plants. Review of more than 60 projects and five case histories reveals that the first three objectives are usually met through sediment removal. The technique is recommened for deeping and for long range reduction of phosphorus release from sediment. Sediment removal to control toxic materials is possible with minimal environmental impact when proper equipment is used, but it may more than double the cost.

AN - 15511107; 333845 AB - A wide variety of hardware suitable for data acquisition is available. The desktop computer based DAS described above was chosen after consideration of cost, system flexibility, reliability, availability of repair service, and management familiarity with a range of hardware. The system was designed in 1979 and because of the rapid evolution of desktop computers, an identical system might not be chosen today; nevertheless, the system performed according to the requirements and ran for several years without requiring replacement. Operating the system was straightforward; no difficulty was reported in training operators to handle the system. The uninterruptable power supplies worked without failure throughout many power line outages. In these applications the most significant advantages of the system have been its flexibility and the ease with which one can make changes in the software to accommodate changes in a given study or to tailor the system to a new study.

This paper summarizes recent data obtained by EPA on identification and quantification of different emissions (i.e. characterization) from a variety of diesel engines. The effects of turbocharging, advanced injection timing, indirect vs. direct injection, exhaust gas recirculation (EGR), and different fuel pumps on HC, CO, NO sub(x), sulfates, aldehyde, and particulate emissions were determined by testing several heavy duty diesel engines. A heavy duty gasoline engine was tested for comparison. Limited testing was done on a diesel bus engine under malfunction conditions (conditions different from manufacturer's recommended specifications). JF - J. AIR POLLUT. CONTROL ASSOC.

The essential characteristics, advantages, and problems associated with personal monitors are discussed and compared to the characteristics of fixed-station monitoring. Personal monitors generally aresuperior to fixed monitors for estimating personal exposure , at least for selected air pollutants. They make it possible to collect data on pollutant concentrations that people normally come into contact with throughout their daily activities -- indoors, outdoors, and in various modes of transportation. These new instruments ultimately could transform the way in which human exposure to air pollution is estimated. JF - J. AIR POLLUT. CONTROL ASSOC. AU - Wallace, LA AU - Ott, W R AD - Off.

AN - 15464912; 271079 AB - The reactivities of five partially-oxygeneated organic compounds were measured. In terms of ozone-forming ability, the most reactive of the organics studied was methyl methacrylate. Vinyl acetate and 2-ethoxy ethanol were found to be moderately reactive. Ethylene oxide and o-isopropyl phenol exhibited low reactivity. Smog chamber contaminaton and its effects on measured reactivity were also studied. It was found that contaminaton can significantly affect the reactivity of slowly-reacting organics. The use of smog chambers, therefore, to obtain reactivity data for low-reactive organics is not recommended.

AN - 15464187; 271074 AB - Groups of 15 rats each were exposed 20 hr/day, 7 days/week for 28 days to a 1:14 dilution of either raw or irradiated exhaust using a six-cylinder Nissan diesel engine. Body weight gains were significantly reduced during exposure to diesel exhaust with a greater decrease during exposure to irradiated compared with raw exhaust. Arterial blood gases and standard bicarbonate remained unchanged. Arterial blood pH was slightly but significantly decreased in the animals previously exposed to irradiated exhaust. Residual volume (RV) and wet lung weight were unchanged after exposure to either condition, while vital capacity (VC) and total lung capacity (TLC) were increased (P < 0.05) following exposure to raw exhaust. The shape of the deflation PV curves were nearly identical among the three groups. It was concluded that 28 days exposure to a 1:14 dilution of diesel exhaust emissions resulted in only minor functional changes in the lungs.

The plotted concentrations are the daily maximum 1-h average and the daily inflow, that representative of air flowing into the metropolitan region during a 4-h midday period. In general, the inflow varies from 30 ppb in the winter to 70 ppb in the summer, but under strong high pressure systems may approach or exceed 120 ppb. Evidence of local ozone production is apparent, with the highest recorded maximum in the two years being 255 ppb.

The agreement covers some two dozen issues related to RCRA, as well as a number of questions involving aspects of the agency's consolidated permit program and the National Pollutant Discharge Elimination System (NPDES). Under the settlement, a company could begin constructing a new hazardous waste management facility as soon as 180 days after it filed Parts A and B of the permit application, assuming the company already had necessary construction approvals from other government agencies. However, such a facility could not begin operating until the company actually received its RCRA permit. JF - SOLID WASTES MGMT.

The suggested design represents a compilation of ideas from states that are currently developing ground-water programs. The outline should provide advice to those states that have not yet begun to develop a program, but recognize the need to do so. Given the limited funds available to develop and implement a ground-water management program, the states should use the design as a guide, and devote their efforts to defining a state ground water protection policy, identifying and evaluating existing and potential contamination sources, and to developing and implementing procedures to prevent or mitigate the contamination problems.

AN - 15416105; 234061 AB - A number of relationships can be obtained from the measurements made of fine-mode and coarse-mode particle mass and particle sulfur concentrations at ten sites in and around St. Louis in 1975 through 1977. Fine-mode and coarse-mode particle mass occur at about equal concentration levels, but with significant variations with quarter of the year and between urban and rural sites. These variations are associated with those of fine-mode sulfur which as ammonium sulfate is the single largest contributor to fine-mode mass. Ammonium sulfate can constitute up to seven-tenths of the fine-mode mass at non-urban sites during the 3rd quarter of the year. The gradient of the several components of the mass between urban and rural sites vary from just over 1:1 for fine-mode sulfur to over 2:1 for coarse-mode sulfur. The gradients for fine-mode and coarse-mode mass between urban and rural sites ranged near 1.5-1. JF - Atmospheric Environment AU - Altshuller, A P AD - Environ. Sci. Res. Lab., EPA, Res.

AN - 15388817; 213329 AB - Duplicate, 8-compartment, continuous-flow microcosms were used to study the effects of acid addition on community function, algal community structure, and degradation of a plasticizer, diethyl phthalate. Inputs of HCl decreased the alkalinity (measured as CaCO sub(3)) from 25 to 8 mg 1 super(-1), creating diurnal H super(+) activity curves that indicated that the ecosystem was being severely stressed. Removal of excess acid was accompanied by a return to a normal diurnal pH cycle. Nutrient concentrations and O sub(2) production did not give a definite indication of stress resulting from the addition of acid. Algal community structure and total biomass were not affected by acid inputs. Also, degradation rates of diethyl phtalate by the aquatic bacteria were similar for the control and the acid-stressed systems. These studies indicate that acid inputs can significantly disrupt normal ecosystem function, such as diurnal pH cycling, without having a measurable impact on other parameters usually monitored in aquatic ecosystems.

AN - 15381615; 212360 AB - An environmental assessment of the transformation and transport pathways of hexachlorocyclopentadiene (hex)in simulated aquatic ecosystems is presented. Hydrolytic and photolytic disappearance rate constants in distilled and natural waters and in sediments-water systems are given. Sediments in defined sediment-water systems do not significantly affect the disappearance rate constants, compared to distilled water values, for the hydrolytic and photoytic processes. Water solubility, octanol/water partition coefficient, and vapor pressure for hex are also reported and compared with literature values. Fate and transport asessment using an evaluative model indicates that hex will not likely reach substantial steady-state concentrations in the various compartments of the simulated ecosystems. The results also indicate that photolysis and, to a lesser extent, hydrolysis are the predominant degradation processes; export via the water column is the predominant transport process.

AN - 15379632; 206537 AB - This paper describes a modeling technique for estimating responses of urban travelers to gasoline shortages under three different procedures for allocating scarce gasoline supplies. The allocation procedures are: allow the price of gasoline to rise to a market clearing level, allocate gasoline by means of white-market coupons, and allocate gasoline by means of traditional rationing. The modeling technique is based on a system of disaggregate travel demand models and provides for representation of non-price restraints on gasoline consumption (e.g. traditional rationing) and for changes in multi-destination travel, as well as for changes in gasoline prices and in modes, destinations for frequencies of travel. The application of the modeling technique is illustrated by using it to estimate the effects of a gasoline shortage in the Washington, D.C., area. The results of this application indicate that in all allocation procedures tested, reductions in non-work trip frequencies and lengths are the main sources of gasoline savings in the presence of shortages. Transit improvements and carpool i ncentives moderate but do not prevent the effects of shortages on non-work travel. JF - TRANSPORT. RES.

AN - 15356249; 181426 AB - Chrome tannery sludge applied to agricultural land may have benefits in terms of added N for crop growth. An experiment was designed to compare tannery waste with commercial N fertilizer and investigate the potential of the waste as an alternative or supplement to commercial fertilizer. Soils with 38% and 7% organic C and N content of 1.3% and 0.2%, respectively, were amended with lime, commercial N fertilizer, or tannery sludge containing 1.6% Cr. A portion of the tannery waste was supplemented with additional Cr super(3+) salt before adding to the soils. The amended soils were analyzed for total Cr, ammonium acetate extractable Cr, selected nutrient and trace element concentrations. The tannery sludge increased soil pH, total Cr and N, S, Ca, P, Mg, and Na concentrations. DTPA extractable Cr increased only when Cr super(3+) salt was added, but soil pH decreased markedly. Electroconductivity of the soils increased with the waste application rate and, at the highest rate of Cr super(3+) salt addition, far exceeded values recommended for successful crop production. The acidic, high salt conditions complicated interpretation of the Cr super(3+) salt addition results. JF - WATER, AIR, AND SOIL POLLUT.

AN - 14229257; 1042129 AB - The existing channel depth in the Hampton Roads is 45 feet. This depth severely limits the ability of larger coal colliers, greater than 80,000 DWT, to load. The U.S. Army Corps of Engineers (COE) extensively studied the feasibility of deepening the channel to 55 feet and found it economically justifiable. In 1980 the COE prepared a Draft Environmental Impact Statement which proposed expansion of the channel to 55 feet but which presented a number of environmental concerns. These concerns centered on the impact of filling 6,000 acres of the Dismal Swamp, potential contamination of ground water supplies from spoil disposal, and changes in salinity in the tributaries to the Hampton Roads as a result of channel deepening.

Details are given for schemes for managed natural systems in the U.S.A. including land application of wastewater or sludge. Tables show treatment efficiencies of wastewater by slow rate land treatment, rapid infiltration, overland flow, wetlands and water hyacinths and the land required, costs, labour, parts and supplies and total energy. Examples of these processes are given. Previous bad management of waste disposal sites leads to real and imagined problems in introducing natural processes now. Possible difficulties include groundwater contamination, disease transmission, odours and political, economic and legal constraints. Climatic conditions can also cause short term problems but the author calls for natural processes to be given full consideration.

However, the applicability of the method required that difficulties in defining the ventilatory characteristics of fish be alleviated. Using the bluegill, Lepomis macrochirus, and lake Superior water (pH 7.5, total hardness, 44-46 mg per litre), three types of coughing manoeuvres could be established: (1) the most common, large amplitude cough owing to interruption and momentary reversal of developing bioelectric potential of a ventilating cycle followed by a substantial burst in potential; (2) a quick spike-like cough, occurring as a momentary pause in potential, followed by a burst; (3) interruption and reversal near the peak of ventilating cycle, and without accompanying burst in potential.

A project to study new sewer designs based on maintaining adequate low flow solids carrying velocity to alleviate sewer sedimentation is described, from which it is shown that there are feasible ways of controlling first-flush pollution from storm loads, largely by increasing conduit slopes and providing cunette sections. There is some discussion on various types of sewer rehabilitation techniques and other ways of controlling infiltration to sewer systems by upstream storage/attenuation. The last part of the article describes combined sewer overflow regulators.

Arsenic levels were high in many of the organisms studied but the element is believed to be present in a relatively non-toxic organic form.

The variables being studied include rainfall, climates, types of receiving waters and the hydrology and geomorphology of the receiving waters. Particular criticisms of NURP : not relating to worthwhile improvements; not considering whether particular forms of a contaminant are actually harmful; using water quality criteria which are not relevant to short exposure urban runoff, and not making bioassays a significant element of the programme, are answered by the authors.

The system was evaluated under varying regimes of temperature and hardness, with minimum zinc concentrations producing a change in fish ventilation rate during 96-hour test periods compared with chronic exposure tests of embryos and early juveniles; the results show that the system is at least as sensitive as more conventional long-term toxicity tests for screening potentially harmful chemicals.

In addition, the water solubility and half-life of the pesticides in lake Superior were determined. The toxicity of controlled release pesticides appears to be similar to that of the technical grade. Slight differences are attributed to degradation and parent compound ratios on the affinity of the polyethylene capsules for the pesticide. Environmental dangers appear to be their potential for chronic effects on aquatic life due to their persistence.

The acquisition system collected the data automatically by monitoring 20 infrared light-emitting diode/phototransistor pairs. The three exposure conditions were a steep chemical gradient in which the metal concentration was increased over time; a steep gradient in which a fish was exposed to a single concentration; and a shallow chemical gradient. With each regime a choice was available for the fish between control and toxicant water. The results indicate that the steep gradient, in which a single fish is exposed to several consecutively increasing doses, is the simplest method and provides data amenable to statistical analysis. The computer-based system is rapid, relatively inexpensive and accurate.

They report the results of laboratory and pilot-plant studies which have been carried out to ascertain the effects of aeration, adsorption and boiling on water containing the solvents. Groundwater rather than surface waters are likely to contain significant concentrations of the compounds and the establishment of acceptable limits is unlikely to be resolved in U.S.A. in the near future. Results of experiments on adsorption preceded by aeration indicate that this system is likely to be an effective treatment. Boiling vigorously for at least five minutes in a well-ventilated area can remove the solvent at point of use. Preliminary estimates of costs vary widely. They were made on the basis of theoretical concepts and available empirical data and emphasize the need for thorough organic analysis and site-specific performance data.

The study has three components: collection of baseline cost data for utilities withdrawing or planning to withdraw water from the Potomac, analysis of various augmentation possibilities under differing demand conditions, and evaluation of different supply strategies as to their cost impact on individual utilities. The study confirmed that Washington's water supply problems are due to political interaction as much as to shortages in water availability and the findings should be invaluable for future evaluation of supply schemes.

Their objectives are to reclaim and reuse wastewater and its constituents, the recovery and conservation of energy and reduction of costs compared with conventional technologies. It is considered that managed natural biological systems which treat and recycle municipal wastewater appear to be suitable for the I/A program. These may involve variations of traditional land treatment concepts (using agricultural lands, forests, ponds or wetlands) or intensive aquaculture systems such as fish farming, nutrient films and hydroponic cultures. The current status and future possibilities of natural treatment systems are discussed and research has shown that overland low flow projects may be efficient and cost-effective for achieving secondary treatment and ammonia removal. Water hyacinth systems are considered to be ready for fairly routine use. The possible environmental problems associated with these systems are described, but it is considered that a multidisciplinary approach should be able to overcome them, as well as the disadvantages of land requirement and lack of operational control.

The 96 hour EC50 (shell deposition) for Eastern oysters, Crassostrea virginica was 0.71 mg per litre. It should, however, be noted that solubility of creosote was incomplete at the higher concentrations used. In the deactivation experiments, glass carboys of creosote in seawater were exposed to outdoor ambient sunlight and temperature. Chemical analysis by gas chromatography gave an estimated half-life for marine-grade creosote of less than 1 week. In bioassays with mysids, creosote toxicity was reduced by 50 per cent between days 3 and 5.

Kinetic models of the disappearance of phosphorus in soils are proposed on the assumption that a fast initial sorption mechanism is followed by a slow secondary precipitation mechanism leading to formulation of relatively insoluble phosphorus compounds. Mathematical models of phosphorus transport processes in soils are then considered, and the results of model predictions shown to be in reasonable agreement with breakthrough curves determined by experiment. Further studies of the effect of ambient variables are called for, while undue reliance on sorption isotherms is claimed to underestimate the phosphorus capacity of soils in practice.

Mercury as MMC was more toxic than as HgCl2 as determined by effects on survival and production of young. Tissue mercury levels tolerated without mortality were 9 times greater when added as MMC rather than HgCl2 . Accumulation was rapid but 35 and 57 per cent of the mercury added as MMC and HgCl2 respectively was lost within 4 days of transfer to control water. The effect of MMC on survival and reproduction was 3 and 28 times greater respectively in flow-through conditions compared to renewed static. In the case of HgCl2 , this difference was less than 2 fold. In static conditions, only 20-30 per cent of the total toxicant was found to remain in the water phase after 7 days.

The potential hazard is essentially a function of the potential to harm the environment, and the level of exposure. The first of these factors can be assessed on the basis of bioassays, while the second can be determined from laboratory measurements of the behaviour of the chemical when subjected to a variety of external forces. Typical determinands of environmental behaviour are the resistance to biodegradation, the effects of sunlight, sorption behaviour and the solubility and volatility characteristics of the substance in question. Other relevant information may be based on structure /activity relationships, a field in which there has been only limited progress to date. Ideally, a thorough study of the physical and chemical properties of a product should enable a theoretical model to be established capable of simulating its fate in the environment.

Standardization of the test procedure is stressed and some published data for freshwater and marine organisms are examined, showing that for certain materials some species of aquatic animals are 5000 times more sensitive than others, whereas for different materials the sensitivity range is less than 50-fold. The criterion of death adopted in assessing the LC50 value is also discussed and the concept of functional death is advanced as a means of taking into account other extreme consequences such as immobilization or loss of equilibrium, which would reduce the chances of survival in the wild to zero.

Sixty eight chemicals for which 96 h median lethal concentration values were available from EPA tests were also tested using the Microtox toxicity analyser based on the luminescent response of Photobacterium phosphoreum cells. A 50 per cent reduction in light output is the criterion for the EC50 of each toxicant. Good correlations existed between the two sets of data in respect of chemicals of similar structure particularly within semihomologous series, but only order of magnitude predictions of fish toxicity data could be obtained from the results f luminescence measurements, which could however be useful for screening purposes.

Survival of newly hatched larvae was the most sensitive indicator of the effect of both pesticides on fathead minnows, Pydrin being approximately 90 times more toxic than Kelthane. The lowest observed effect concentrations for these insecticides were 13 times less than the 96 h LC50 value established using standard fish bioassays with fathead minnows. For Kelthane bioconcentration factors of 3700 for fathead minnows and 10,000 for amphipods were recorded, and the mean concentration factor for Pydrin in minnows was 3200. Residual levels and concentration factors for both pesticides increased with increasing test concentrations in the water. JF - Aquatic Toxicology and Hazard Assessment (edited by J. G. Pearson. R. B.

The results of the system are reported with respect to the effects of copper and cadmium on the responses of Stage 2 and 3 nauplii of the barnacle Balanus improvisus. Both metals altered non-directed (spontaneous) swimming activity in a dose-related biphasic manner. Hyperactivity in response to low-level concentrations was followed by suppressed activity in the presence of higher metal concentrations. Copper also altered phototaxis in these nauplii; at higher concentrations (72 and 138 ug per litre) a shift to negative phototaxis was observed in some individuals. The sensitivity of these behavioural responses is compared with that of two developmental parameters monitored in the course of the same assay.

The purpose of the program was to focus scientific research to meet management objectives. A preliminary summary of the scientific findings indicates the following major problems: The upper Bay, mid Bay, and eastern shore tributaries are either highly or moderately nutrient enriched compared to historic levels. Sediments in the upper Bay and middle Bay have elevated levels of metals. Nonpoint sources are a significant source of nutrients, particularly nitrogen. Point sources are the major source of phosphorus for the severely enriched areas. The major reivers such as the James, Potomac, and Susquehanna are important contributors of nutrients, metals, and synthetic organic compounds. JF - Atlantica.

The conditions governing the effectiveness of each of these processes are discussed, both as regards the specific pollutant and the medium in which it is present. Recognizing that compounds with similar chemical and physical properties are likely to undergo removal to roughly the same extent, organic priority pollutants previously detected in treated sewage were classified into six different groups according to their reported concentrations, namely 1.0, 5.0, 10.0, 25, 50 and 100 ug per litre. The data relating to selected compounds in the 10, 50 and over 100 ug per litre clusters are presented and discussed from the standpoint of chemical and structural similarities, and their effect on treatment performance.

AN - 13838555; 696228 AB - This paper discusses the potential effects of drilling fluids on semienclosed bodies of water, such as estuaries. Fluids used in the extraction of oil and gas in offshore and coastal waters are comprised chiefly of a mixture of barite, water and chemical additives and are pumped into the well through the drill pipe and the drill bit. Drilling fluids have been discharged into outer continental shelf waters for many years, but there is some concern of potential ecological impact when they are discharged near coral reefs or in bays and estuaries. The concern is based on potential adverse effects of the fluids on corals, shellfish, finfish, grass and general productivity.

They were monitored in air samples using a personal air quality monitor and in breath using a spirometer. Tap water levels were compared to those in human breath. Total trihalomethanes (THM) exceeded the interim drinking water standard of 100 ng per ml in all samples from both areas. Chloroform and tetrachloroethylene levels were higher in the non-industrial area. Bromodichloromethane levels were similar in both areas. Small amounts of chlorobenzene occurred but no benzene, carbon tetrachloride, 1,2-dichloroethane, vinylidene chloride or 1,1,1trichlorethane were detected. Of the total daily intake of VOC through air and water, drinking water was an important contributor of only two of the compounds measured, chloroform (79 per cent) and bromodichloromethane (76 per cent).

Screening models are illustrated by describing a methodology applicable to large areas of land and another applied to a large number of chemicals. The application of models in a planning context is illustrated by a local planning agency's use in developing nonpoint source control strategies and by the federal government's use in assessing potential exposure to a pesticide. Development of design criteria is illustrated by summarizing the long history of model use to develop effluent limits in the Holston River basin (Tennessee).

A "block-shaped" model vehicle was fixed in position over the test-section floor while the floor moved at the freestream air speed to produce a uniform, shear-free, approach flow. This simulates an automobile traveling along a straight highway under calm atmospheric conditions. Vertical and lateral profiles of mean and fluctuating velocities and Reynolds stresses in the wake of the vehicle were obtained using a hot-film anemometer with an X-probe. Profiles were taken at distances of 10-80 model heights downwind. A momentum type wake was observed behind the block-shaped vehicle. The wake doses not have a simple self-preserving form. However, it is possible to collapse the velocity deficit with one length and one velocity scale. JF - Atmospheric Environment AU - Eskridge, R E AU - Thompson, R S AD - Meteorol. and Assess.

AN - 13622054; 513395 AB - Once a risk has been identified, risk estimation requires the determination of dose-response functions that can be applied to expected doses. That is, toxicity and exposure analyses are the critical elements in risk assessment. There are four major methods to examine toxicity: (1) epidemiological evidence of actual human response; (2) animal (in vivo) experiments; (3) short-term in vitro tests; and (4) structure-activity analysis. Where data are available, the Environmental Protection Agency (EPA) uses one or a combination of the first two approaches. While short-term tests and structure-activity analysis are accepted as useful screening devices to help set priorities for further testing, there is no accepted procedure for their use in predicting human response to specific chemicals or exposure levels.

AN - 13619285; 513402 AB - In a wind tunnel study, the influence of the highly turbulent region found in the lee of a model building upon plumes emitted from short stacks was examined through smoke visualization and tracer gas concentration mappings. A thick, simulated atmospheric boundary layer was used to provide background dispersion. A rectangular-shaped building with its length equal to twice its height and width was oriented with the long side perpendicular to the approaching wind. The stack was placed midway along the lee side of the building. In all phases of the study, each smoke or tracer release from the stack was repeated with the building removed. This allowed for a simple demonstration of the buidling wake effects. A simple mathematical model was developed that provided good estimates of concentrations in the building wake. The building influence was found to be reduced with increases in the effective source height. JF - Atmospheric Environment AU - Huber, AH AU - Snyder, W H AD - Meteorol. and Assess. Div., Environ.

AN - 13607847; 486823 AB - In studies designed to test whether disinfection practive contributes significantly to the tumor initiating activity found in drinking water mixed results have been obtained. In one experiment, water disinfected by chlorination, ozonation or combined chlorine resulted in a significantly greater number of papillomas when compared to nondisinfected water. In two subsequent experiments, where water was obtained from the Ohio River at different times of the year, no evidence of increased initiating activity was observed with any disinfectant. Analysis of water obtained at the comparable times of the year for total organic halogen, and trihalomethane formation revealed a substantial variation in the formation of these products. Comparisons of the specific mutagenic activity of the chlorinated products suggests that the commercial material might provide a useful model for studying health hazards associated with disinfection reactions by-products.

AN - 13606733; 486743 AB - Concern over the presence of trihalomethanes and other chlorinated by-products in chlorine-disinfected drinking water has led to extensive investigations of treatment options for controlling these by-products. Among these treatment options is the use of an alternative disinfectant such as chlorine dioxide. Although chlorine dioxide does not react to produce trihalomethanes, considerable evidence does exist that chlorine dioxide, like chlorine, will produce other organic by-products. The literature describes chlorinated and nonchlorinated derivatives including acids, epoxides, quinones, aldehydes, disulfides, and sulfonic acids that are products of reactions carried out under conditions that are vastly different from those experienced during drinking water treatment. Evidence is beginning to emerge, however, that some by-products in these categories may be produced. JF - Environmental Health Perspectives AU - Stevens, A A AD - US EPA, Munic. Environ. Res.

AN - 13606080; 486914 AB - Chloroform is a drinking water contaminant that has been demonstrated to be carcinogenic to mice and rats resulting in an increased incidence of liver and kidney tumors, respectively. The mechanism of chloroform carcinogenicity might be by tumor initiation and/or promotion. Since induction of ornithine decarboxylase (ODC) activity has been proposed as a molecular marker for tumor promoters, the authors have investigated the effect of chloroform on ODC activity in rats. Chloroform induced a dose-dependent increase of hepatic ODC with an apparent threshold at 100 daily dosing of chloroform for 7 days the liver became less susceptible, with the last dose of chloroform resulting in only 10% of the activity observed after a single dose. Nuclear RNA polymerase I activity was also induced by chloroform.

AN - 13543273; 441172 AB - During the Regional Air Pollution Study (RAPS), winds in the St. Louis region were recorded by surface stations (hourly averages) and by multiple upper air releases (on-the-hour). This study analyzes differences (1) between upper air and surface resultant winds, (2) among upper air winds at 4 sites, and (3) among surface winds at 25 sites. The extensive data set provides a statistical basis for indicating the representativeness of individual observations, and the results show considerable variation between simultaneously-measured winds determined by alternate means. Based on Gaussian plume dispersion, the spatial variations in wind direction are translated into expected departures between predictions and observations of pollutant concentrations. Inaccurate specification of winds in air quality simulation models is likely to be a substantial contributor to differences between short-term predictions and observations on an urban scale.

(1) The traditional agressiveness index based on calcite saturation is inadequate to describe the degradation of asbestos cement pipe. The presence of naturally-occurring protective materials, pH, carbonates, calcium, disinfectant concentrations, temperature, and organic matter must also be considered. (2) Some materials cause pipe matrix dissolution but do not necessarily release asbestos fibers. (3) The chloride, sulfate, and orthophosphate salts of zinc are satifactory corrosion inhibitors for asbestos cement pipe at the proper concentrations and pH. The mechanism involves formation of a zinc hydroxy carbonate precipitate which reacts with the pipe surface to form a harder zinc silicate coating. (4) Tthe Zn orthophosphate protects against corrosion in a metal-asbestos cement pipe system through the action of the orthophosphate rather than Zn. Zinc chloride and sulfate are not effective in these situations. (5) A degraded asbestos cement pipe with loose fibers cannot be readily rehabilitated by Zn treatment. (6) Results of Zn solubility modeling presented in this paper are also applicable to studies of new galvanized piping.

Corrosivity may result from low pH, low buffering capacity, presence of dissolved oxygen, high total dissolved solids, high halogen and sulfate/alkalinity ratio, and high temperature. The major health effects of corrosive water are lead toxicity, increased incidence of hypertension and cardiovascular disease produced by cadmium, and the possibility of cancer from ingestion of asbestos fibers. Possible benefits of reducing corrosivity are less health risk, fewer operations and maintenance problems, and improved esthetics (reduction of discolored water and stained fixtures). Negative effects of increasing the water hardness to reduce corrosivity are negligible. Evidence indicates that water treatment to reduce corrosivity is warranted, especially for larger systems. Costs per life saved vary from $1720 (145 lives saved per year) in a 100 mgd plant serving 1 million people to $114,000 (0.0036 lives saved per year) in a 2500 gpd plant serving 2500 people. Annual per capita costs for lime treatment of soft water range from 25 cents for the 100 mgd plant to $16.40 for the 2500 gpd plant. This study illustrates the uncertainties involved in placing an economic value on benefits from reduction in incidence of diseases.

Although the precursors and processess are widely used, it is only the particular critical combinations that produce priority pollutants. Most of these are associated with the early stages of production and are generally refined away on the route to the commercial product. Of the 116 recognized organic priority pollutants, 75 were verified in this study. Although some feed stocks such as acrylonitrile, phenol, and vinyl chloride are themselves priority pollutants, some are also introduced as impurities or reaction products of impurities in feedstocks or solvents. A table lists the 17 plastics and synthetic fibers effluents which contained greater than 0.5 ppm of priority pollutants, the monomers, and the chemical nature of pollutants generated. A similar table lists 71 organic chemical effluents which contained greater than 0.5 ppm priority pollutants, with the generic processes, feedstocks, and chemical nature of pollutants generated.

If the ratio is greater than 1, the source is classified as dirty, and if less than 1, as clean. When severities downstream from the source are of interest, a transport model must be used to relate the concentrations to factors measured at the source. Use of a multiplicative model on an effluent discharge from an industry is illustrated. The model is designed to classify a large number of the clean-dirty borderline cases as dirty, while minimizing the number of rather clean sources which are classified incorrectly. Another illustration using a textile plant effluent measured total suspended solids over 40 days to produce 57 observations. Considering only one measurement, 47 of the 57 cases were designated as dirty, but taking two observations on each of five representative days produced a clean classification. Severity at a downstream point can be calculated using concentration of pollutant in effluent, effluent discharge rate, river flow rate, and the standard concentration.

AN - 733443469; 16345869 AB - Using batch cultures, we determined transformation rates for low concentrations of two toxicants-an insecticide, methyl parathion (O,O-dimethyl O-p-nitrophenyl phosphorothioate), and a plasticizer, diethyl phthalate-by aufwuchs, aquatic microbial growth attached to submerged surfaces or suspended in streamers or mats. Aufwuchs samples were collected from field sites, an indoor channel, and a continuous-flow fermentor. Aufwuchs fungi, protozoa, and algae did not transform methyl parathion or diethyl phthalate, but bacteria rapidly transformed both chemicals. Second-order transformation rate coefficients, K(b), based on total plate counts of bacteria in aufwuchs, were determined for potential use in a mathematical model capable of predicting the transport and fate of chemicals in aquatic systems. K(b) for both methyl parathion and diethyl phthalate decreased as the concentration of total bacteria, [B], increased in aufwuchs. This effect resulted from the proportion of nontransformer to transformer bacteria increasing as [B] increased and from the rate of transformation per transformer cell decreasing as [B] increased. First-order transformation rate coefficients, K(1), were relatively stable per unit of surface area colonized by aufwuchs, because K(b) decreased as [B] increased (K(1) = K(b) x [B]).

Water containing 1.0 or 0.2 mg per liter of the organic compound was applied at the rate of 14 cm per day for 45 days. Concentrations of compounds in the effluents and the amounts volatilized were determined and the mass balances calculated. Chemicals which percolated rapidly through the soil without degradation were chloroform, 1 ,2-dibromo-3-chloropropane, dichlorobromomethane, 1 ,2-dichloroethane, tetrachloroethene, 1,1,2-trichloroethane, and trichloroethene; retardation factors (velocity of tritiated water through the soil divided by the apparent velocity of pollutant through soil) were 2.5 or less. Little or no biodegradation was observed. From 19 to 65% of chemical applied to the surface reached the 140 cm depth, and the rest volatilized. Retardation of chlorinated benzenes generally increased with decreasing water solubility. Some degradation occurred in this group of compounds. Bis(2-chloroethyl) ether did not degrade, and its retardation factor was < 1.5. A method was developed to predict the retardation factors on the basis of water solubility of the chemical and soil organic C content. Soils containing low organic matter are more pollution-vulnerable. (Cassar-FRC) JF - Journal of Environmental Quality Vol 10, No 4, p 501-506, October/December, 1981. 3 Fig, 4 Tab, 34 Ref.

In 1977, under the Section 208 Program, 353 lakes were assessed. In 1979, a more quantitative assessment of 64 lakes was undertaken. Sample parameters and preservation/analysis methodologies are provided. The 1980 Ambient Lake Monitoring Program establishes baselines and defines trends in lake water quality, and identifies new or existing problem areas. The pilot Volunteer Lake Monitoring Program will allow citizens to learn about lakes/lake management and also provide baseline information that would not otherwise be gathered, due to limited resources. The Clean Lakes Program determines lake water quality problems, examines alternatives for improving water quality, and implements these alternatives. The USEPA has specific regulations for administering the Program and has established three types of assistance: lake survey and classification, Phase 1 diagnostic/feasibility study, and Phase 2 implementation awards. Awards are for publicly-owned freshwater lakes and are only made to state agencies. Phase 1 awards are up to $100,000 and require a 30% non-federal cost share. Phase 2 awards require a 50% non-federal share. These awards are not contingent upon one another. The Illinois EPA applies for the funds and administers the program. In July 1980, the Illinois EPA received a one-time federal grant of $100,000 (70% federal, 30% state) to develop the state 's lake classification and priority ranking. It also received awards for three Phase 1 diagnostic/feasibility study projects in July 1980 totaling $104,650. The program needs public support to succeed.

The water quality, use impairment, and characteristics of these lakes are influenced by origin, location, morphology, hydrology, watershed characteristics, and meteorological conditions. This report discusses six artificial impoundments in Central Illinois that were part of the Illinois Environmental Protection Agency 's (IEPA) 1979 lake sampling program. The six lakes, Otter, Lincoln Trail, Pittsfield, Mattoon, Paradise, and Taylorville are ranked for expected water quality based on mean depth, watershed equivalent inches, retention time, and drainage area to storage capacity ratio. To assess water quality, Carlson 's Trophic State Index (TSI) is applied to Secchi transparency, chlorophyll a, and total phosphorus data. Total suspended solids (TSS) and nonvolatile suspended solids (NVSS) are also included. Otter Lake has the best physical characteristics; however, the August 1979 TSI average values show Lincoln Trail with the best water quality, probably as a result of its higher percentage of cropland to woodland. Lake Taylorville ranks fourth on the list because the TSI value for chlorophyll is low---a result of high turbidity and a short retention time. Better water quality is related to long retention time, low watershed area to lake capacity ratio, and greater mean depth, as well as little urbanization, less row crop cultivation, and soils with low fertility and erosivity. As these characteristics become less desirable water quality tends to decline. (Atkins-Omniplan) JF - Proceedings of a Round Table on Reclaiming and Managing Lakes in Illinois October 10-11, 1980.

Cluster analysis of the raw spectral dat established distinctive lake groups, each comprised of water bodies having similar optical and physical properties. The spectral properties of each lake provided an integrated characterization of water quality and related use impairment problems. The trophic parameter estimates, as well as lake clusters and rankings derived from them, were in general agreement with contact-sensed data and with the raw spectral data.

For the most part these permits limited the conventional pollutants: biochemical oxygen demand (BOD), total suspended solids (TSS), oil and grease, pH, as well as ammonia, metals, and phenols. In 1977 the Clean Water Act was passed to focus attention on controlling toxic pollutants. By July 1, 1984, industry is to meet minimum technology requirements, which means the best available technology economically achievable must be used for controlling toxic pollutants, and best conventional pollutant control technology used to control conventional pollutants. Permit issuance procedures have changed little since 1973. The law requires the EPA to consider more stringent limits for conventional pollutants in the second round permits, but such limits will only be imposed where additional required facilities meet a cost-reasonableness test. EPA will review the treatment facilities employed to meet present requirements and then determine what logical modifications or additions might further reduce conventional pollutant levels. Major emphases of new permits will be the control of toxic pollutants. Reductions in pollutants will most likely be achieved by: optimization of existing treatment systems most industries installed to meet current requirements; isolation at the source and separate treatment; process chemical substitution; or housekeeping improvements. Large scale application of advanced wastewater treatment techniques is not expected. (Baker-FRC) JF - Civil Engineering (New York) Vol 51, No 9, p 76-78, September, 1981. 2 Tab.

Mass loadings are usually specified in NPDES permits, and flow data is critical to calculating pollutant loadings from unit concentration. Flows are measured in two ways: instantaneous and continuous. Instantaneous flows must be determined at the time samples are taken for analysis to calculate the pollutants discharged at a particular instant. In a continuous flow measurement system, the flows are totalled to obtain a value for total flow, used to verify NPDES compliance. There are four basic methods for determining flow: weighing the discharge, volumetric methods, sump pumps, and orifice buckets. Flumes, meters, and weirs are the kinds of devices normally employed to measure open channel flow. Other methods include: pitot tubes, head measurement, energy grade line calculations, orifices, nozzles, venturi flowmeters, open-pipe methods, open channel methods, stream gauging, dilution and tracers. Exotic methods sometimes used include: electromagnetic flowmeters, acoustic flowmeters, conductivity cells, hot-wire anemometers, and warm-film anemometers.

According to EPA regulations, trihalomethanes, primarily formed by chlorination of humic materials in raw water, must not exceed 0.10 mg per liter in drinking water. Of the three unit processes--oxidation, aeration, and adsorption--each has advantages and disadvantages. Granular activated carbon, when fresh, is most effective in removing precursors, but this excellent performance is not long-lasting. Clarification, source control, oxidation, adsorption, biological degradation, and pH lowering also significantly lower precursor concentrations. The advantages and disadvantages of alternative disinfectants are discussed. Ozonation is very effective but has no residual action within the distribution system. Chloramines are easy to use and produce residual disinfection but are suspected of being toxic. Chlorine dioxide is very desirable as a disinfectant, but residuals in drinking water may exceed the 0.5 mg per liter limit. Four examples of treatment systems using chlorine as a disinfectant are discussed in detail to illustrate the evaluation process.

About half of all on-site systems fail to perform satisfactorily over their entire design life of 15 to 20 years. Elevated sand mound disposal systems have been used in Pennsylvania, since the soil is generally not suitable for conventional on-site effluent disposal systems. However, about 40 percent of these systems malfunctioned in less than 5 years. Since the malfunctions were associated with observations of surface discharges of effluent, this study investigated the ability of the soil to transmit effluent from an elevated sand mound to the groundwater system. It was assumed that both the infiltration surfaces and the groundwater system were able to accept the effluent. The flow calculation method used was predicated upon separation of the effluent flow into horizontal and vertical flow components. Darcy 's law written in cylindrical coordinates was used to calculate horizontal flow. Vertical flow was calculated, assuming that flow was limited by a single, slowly permeable layer of known thickness. The calculations demonstrate that the lateral plus vertical flow capacity of the soil must exceed the anticipated effluent input if the disposal system is to perform satisfactorily. Data requirements for evaluation of the suitability of a specific site for disposal of household wastewater using a mound system are identified. Calculations made using data representative of many of the failing mound systems in Pennsylvania indicate that these failures result from the inadequacy of the combined lateral and vertical flow capability.

Although wastewater P loading was reduced by 99% and loading from all external sources by 80%, the lake continues to be highly productive, especially during July and August. The source of P was internal, corresponding to internal supply rates of 240-680 kg per week over a 3-9 week interval in summer. The P release took place during anaerobic conditions, the time of which varied from year to year (1971-1975). The P content of the surface sediments was 0.2-0.5% dry weight, and a large proportion was potentially mobile, 27.7 to 72.8% (NaOH extractable). The upper 10 cm of sediments was estimated to contain 50,000 kg of potentially mobile P, enough to supply P to lake water for about 20 years at the present release rate.

Mass increases of 2,000-2,900 kg (35-50 mu g.liter super(1) ) were measured, corresponding to internal supply rates of 240-680 kg.wk super(1) over a 3-9-week interval. After anaerobi: conditions developed in late June, release from the profundal zone sediments contributed significant amounts of P to lake water. Sediment chemical properties were determined to estimate the size of the P reservoir in the profundal zone (at water depths > 6.5 m). The P content of the surficial profundal zone sediments was 0.2-0.5% (dry wt) and a significant fraction was potentially mobile (NaOH extractable). We calculate that the upper 10 cm of these sediments contain 50,000 kg of potentially mobile P, of which a small fraction is released each summer. Although external sources of phosphorus have been reduced by about 80%, the feedback of P from the sediments is supporting the productivity of Shagawa Lake and may continue to do so for many years.

Stream nutrient concentrations were compared in sets of 80 and 175 relatively large watersheds with varied patterns of forest and agricultural land use. The importance of proximity of general land use types to main streams in affecting mean annual stream nutrient concentrations was tested by comparing two models, both considering the land use pattern, but one also taking into account proximity. The results indicate that consideration of the proximity of the land use did not improve the predictive ability. This is partly attributable to the negligible effects of near-stream vegetation in reducing stream nutrient levels.

An extensive table is included which summarizes the acute and chronic toxicity of inorganic and organic pollutants to freshwater fish. Published literature included many reviews and symposia which presented information on water quality, physical and chemical pollutants, and industrial and municipal effluents. These include the aquatic toxicity of Cu, Cn, V, and chlorophenol, and the effects of natural and artificial sources of radiation. Other papers concerned the effects of Hg, the effects of mosquito control agents, and the relationship between biotransformation and toxicity of xenobiotic chemicals in fish. Most of the articles cited deal with the effects of chemical pollutants. Papers are cited which deal with the effects of chlorine and wastewater, and pulp and paper wastes.

Research included an evaluation of the use of granular activated carbon whicch identified needed research including investigation of the factors responsible for the initiation of microbial growth on GAC surfaces and the microbial generation of organic compounds during carbon treatment. A study on the inactivation of cell-associated poliovirus and coxsackievirus found that higher ozone residuals were required than for nonassociated viruses. Also, natural poliovirus isolates found in drinking water were more resistant to chlorine inactivation than were standard laboratory virus strains. One study examined 23 potable water supplies for viruses and found ten virus positive samples. An investigation of water encrustations from seven water systems by scanning electron microscopy found algae, actinomycetes, diatoms, and filamentous and flagellated bacteria. Several studies supported the concept that microorganisms promote a localized corrosion of metal and tubercle formation, and that the microbial ecosystems influence the concentrations of numerous constituents in distributed waters.

Many cases of plant workers exposed to pathogens and chemicals are reported--chlorinated organics, hydrogen sulfide, bacteria, and endotoxins. Several studies done on risk of bacterial and viral exposures for plant workers and nearby populations failed to show significantly higher illness rates. Several papers discussed the hazards of wastewater discharges with respect to swimming, transmission of antibiotic resistance factors, and viruses. Although exposure to sludge composting did not produce a high incidence of illness, protective measures and regular health examination for workers are recommended. Of particular concern is Aspergillus fumigatus. Studies on land application of wastewater and sludges revealed few ill effects in animals fed sludge, crops grown on sludge amended soils, or exposed humans. However, some potential and actual cases of disease transmission were noted: grazing animals, persons living in kibbutzim practicing wastewater spray irrigation, well water pollution, a cholera outbreak, and leptospirosis incidence. Potential chemical threats from land application are pesticides, polynuclear aromatic hydrocarbons, toxic trace elements (particularly Cd), and nitrates. There is not much information on health effects of treated wastewater reused as part of the potable water supply, but it is preferable to use renovated water for nonpotable uses. Of great concern are pathogens and mutagenic or carcinogenic materials, such as halogenated organics, in reclaimed water.

Highest total concentrations (up to 1700 ppb in mussels, <1 ppt in particulates) were found in the highly polluted upper bay, decreasing with increasing distance from the industrial area. In the lower bay, 37 km from Providence, concentrations in particulates were 20 times lower than in the upper bay. Less than 80 ppb were found in mussels 34 km from the upper bay. A potential source of the pollution is a chemical plant which manufactures 2,4,4 ' - trichloro-2 ' - hydroxydiphenyl ether.

Biological monitoring is defined as the use of a living organism to measure, for a specific time and location, the presence or amount of a substance in the environment or in man, or the effect of a substance on the environment or man. The organism may be a naturally present or introduced species in the environment, or in the laboratory, or in a simulated environment or microcosm. Biological monitoring offers great promise for detecting specific chemicals and has the advantages of greater biological relevance, greater sensitivity, and ability to indicate actual or potential exposures. Most of the emphasis has been on monitoring of aquatic systems, but biological monitoring can be applied to air and terrestrial systems.

Although storm water pollutant concentration varies with time and location during a storm and from one storm to another, the BOD5 is usually close to that of municipal sewage secondary effluent, and the suspended solids concentration is similar to that of raw sanitary wastewater. Combined sewer overflow quality lies between that of untreated sanitary sewage and urban storm runoff. Physical treatment units are more effective than biological systems because they can handle the highly variable flow rates and pollutant concentrations. The treatment chosen depends on the desired use: low level treatment for irrigation water and high level treatment for boiler feed water. A table lists four categories of waters, AA, A, B, and C, with the maximum concentrations of metals, anions, color, etc., allowed for each classification. A hypothetical case study of a 100 acre industrial complex illustrates the planning process. After the demand and quality requirements in each category of water quality are decided, storage and treatment facilities are designed for each class of water. Next, costs are determined. Three reuse alternatives are compared: all city water, all storm water except for potable water, and all storm water except for potable water and process water. The cheapest alternative in this case reuses stormwater for irrigation process and cooling water and gives a total water supply cost of $1.54 million, saving $800,000 over the use of city water for these purposes plus for potable water.

Approximately 38 percent of the total state population and 82 percent of the rural populaton relied on an underground water source for drinking water as of 1970. A wide variety of activities can lead to groundwater pollution, includng waste disposal sites; improper well construction; land application of potential pollutants such as fertilizers, pesticides, and road salt; mining and quarrying; individual sewer systems; and transportation of hazardous wastes. Various control strategies are possible. Illinois should (1) examine state agency jurisdiction to identify over laps or gaps in existing regulations; (2) examine the role of non-regulatory and scientific entities in the state to ensure coordination between such programs; (3) increase public awareness of the importance of groundwater as a valuable natural resource and identify existing public values and perceptions of underground water; (4) encourage public participation in program direction and development; (5) utilize the interagency groundwater task force to increase cooperation among involved state agencies on groundwater related strategies, determine the availability of data to decision-makers and identify technological practices; and (6) continue development of a comprehensive groundwater quality management program. Funds and technology-sharing must be sought from the federal government.

Ground water quantity problems can be attributed to cyclic drought conditions. Conflicts between groundwater users have been noted in a number of areas and are usually the result of well interference between two or more large users or one large user affecting water levels in nearby shallow wells. For the most part, the problems have been resolved voluntarily by adjusting pumping rates and schedules, or by developing additional production wells beyond the area of pumping interference. Ohio, being a densely populated and highly industrial state, generates large volumes of both liquid and solid wastes. Based upon groundwater complaint investigations conducted by the Ohio EPA over the past eight years, the most prevalent ground water contamination problems are from domestic on-lot sources affecting private individual wells. Contamination has most often been the direct result of poor well construction and maintenance, or improper well abandonment. Other leading causes of contamination have been salt water effects related to oil and gas production or improperly plugged oil wells, and coal leaching effects. Ohio 's major concerns in ground water program planning are to define agency roles and coordinaton, determine staff capability and training, develop public education and awareness, and increase data collection and regulatory practices.

Water Solubility and the Molecular Fragment Mobility Coefficient AN - 19226707; 8103340 AB - This is the second in a series of studies evaluating the use of various molecular modelling techniques to estimate the mobility of organic chemicals in soils. The objectives of this study were to identify molecular fragments within organic chemicals that may significantly enhance or retard mobility in soils; identify fragments that do not significantly enhance or retard mobility; quantify the fragment effects; and incorporate these effects into the estimation method that predicted mobility from the logarithm of the solubility. Soil thin-layer chromatography was used to quantify the mobility of 55 pesticides, having diverse chemical structures, in Hagerstown silty clay loam soil. Thirteen fragments were identified and divided into two groups. One group of fragments possessed an electronegative or electropositive character whose mobility enhancement or retardation effects were not created by, or were negligibly affected by, aromatic ring resonance. In the second group, ring resonance played an important role in establishing mobility effects. Two least squares multiple regression models, incorporating water solubility and quantifying the surface repulsion or attraction effect as a molecular fragment mobility coefficient, successfully predicted the retention factor. These two models were superior techniques for predicting the mobility of diverse organic chemicals compared to the estimation technique utilizing solubility as the only independent variable.

There are about 11,000 such facilities in the United States. The emphasis of information gathering in this study was on plants with production of more than 93 sq m product per day, which as a group accounts for 1 ,100 plants and 88% of the U.S. production. The toxic pollutants in the plant wastewater are silve, cyanide, and chromium. Silver is present in all wastewater, but cyanide and chromium are only present when the facilities use bleaches containing them. Cadmium may be present in some wastewaters as it is a component of some photographic emulsions. Up to 85% of the silver and cyanide are recovered, using conventional in-process controls, primarily for the economic benefits. Some plants are using advanced in-process controls such as ion exchange, reverse osmosis, countercurrent washing, and wash water recycle, which produce conservation and environmental benefits. There may also be a cost benefit for the larger plants. No facilities are known to regenerate chromium from their wastewater, but treatment systems are available to do so. Pollutant levels in wastewater are given in kg/100 sq m of product, to encourage water saving. The plant mean data, after the basic wastewater treatment, for silver, cyanide, and chromium are 0.14, 4.8, and 0.088 kg/1000 sq m, respectively.

The leachate simulated the high organic strength leachate produced by a young landfill. The specific oxygen utilization rate in the spike system and control system generally paralleled each other with the exception of an increase in the spike system following addition of the leachate. The sludge volume index increased after the first leachate, then declined with the subsequent additions, but during the 400 mg/l COD period the mass of bacteria increased uncontrollably and filled the clarifier. The oxygen demand with 400 mg/l COD was 75 mg oxygen/h compared with 38 mg oxygen/h for the control. The activated sludge process was able to treat a synthetic leachate with COD of up to 200 mg/l but at 400 mg/l the increase in sludge mass and degradation in sludge settling characteristics resulted in the sludge volume overloading the clarifier.

The research activities in these three general areas are classified into five categories: leachate forecasting, controlled decomposition, co-disposal, manuals of practice, and economic assessment. Leachate forecasting includes studies to predict volume and composition of leachates, gas production, and their migration and management. Controlled decomposition is intended to control the quality and volume of leachate production by altering the decomposition processes, controlling waste leachability, and use of liners/membranes/admixtures. Studies are being conducted on co-disposal of municipal wastes with industrial and sewage sludges, with leachate quality control or recirculation. Manuals of practice are being developed concerning the environmental impacts of special types of landfills, sampling and preservation of groundwater, and the use of gas barriers and growth of trees on closed landfills. An effort is being made to evaluate the relative importance of the various factors affecting the costs of sanitary landfills, in order to identify the least costly disposal alternative under local conditions.

A major objective of the Monitoring and Data Support Division Study was to determine the relative significance of the major source types- residential, commercial and industrial - in contributing priority toxic pollutants to POTW influents. The collection systems from eleven residential areas, ten commercial areas, and five industry-dominated areas in four different cities were sampled. The influent to the POTW and tap water were also sampled. All of the 129 priority pollutants were looked for, but 67 were not found in collection systems of four POTW's. The most prevalent pollutants detected were metals, solvents, and phthalate ester plasticizers. Industrial sources appear to dominate the loading on the POTW for most pollutants, while residential and commercial contributors are still important for some pollutants, although at a lower total loading when industrial sources are not present. The type and size of industry present was a significant factor in detecting the presence and concentration levels of the priority pollutants.

Those materials analyzed include semivolatile organic priority pollutants and the heavy metals. The basic approach in this project is to operate parallel sequences of the unit processes. One treatment train is operated as a control; the other sequence has the organic compounds being studied added in a toluene solution. The initial spiking provides a concentration of 50 micrograms/L for most of the organic compounds being studied. All process flows, sludges, and off-gases are sampled so the behavior of the spiked chemicals and indigenous metals can be quantitated. Although not enough tests have been completed to provide definitive data on removal of these materials, especially metals, initial findings are that recoveries of organics range from 70 to 90% for the PAH's, from 70 to 100% for the phthalates, from 95 to 100% for phenols, and from 90 to 100% for the pesticides.

Included are discussions of the pretreatment requirements in the Clean Water Act of 1977, EPA 's general pretreatment regulations, and the procedure used to establish categorical pretreatment standards. Significant problems (addressed by the Clean Water Act of 1977) caused by discharges to publicly owned treatment works (POTW) include interference with POTW operations (fires, corrosion, explosions, hazardous fumes, system upsets); incompatibility, such as interfering with sludge disposal; and the passage of discharges through POTW. Categorical pretreatment standards are based on the degree of treatment that can be obtained by different technologies, considering the economic impact of those technologies. The philosophy behind establishing uniform categorical pretreatment standards is that all industries in a category, or subcategory, should have to treat their wastewater to the same degree of treatment.

A summary of THM regulations lists the monitoring and reporting requirements. Exposure may be minimized by using disinfectants which do not generate THMs in water, by reducing precursor concentrations prior to chlorination, and by removing THM after formation. Average annual costs per residence for removing excess THM from regulated systems (serving more than 10,000 people) are estimated at $1.40. Two surveys of drinking water in 80 and 113 cities respectively revealed an average total THM concentration of 0.053 to 0.117 mg per liter. Chloroform was found in the largest amounts, up to 75% of total THM. Most chloroform toxicity and metabolism studies have used high doses; mammalian responses include central nervous system effects and damage to kidneys and liver. Chloroform-induced teratogenesis and carcinogenesis have been reported, and similar studies on the brominated haloforms are underway. Although the levels of THM in drinking water are generally very low, it is not difficult or expensive to reduce the contaminant levels. The goal is to provide drinking water as free of adulterants as technology permits. (Cassar-FRC) JF - Environmental Science and Technology Vol 15, No 3, p 268-274, March, 1981. 6 Tab, 25 Ref.

The most familiar types of assistance are those activities specifically directed toward problem areas, such as technical assistance, demonstration projects, contracts and studies, and emergency assistance. State and regional offices of the Environmental Protection Agency (EPA) have many programs designed to assist communities in complying with the Safe Drinking Water Act and to provide technical assistance. Other activities of the EPA include demonstration projects, the Model State Information System, and the National Rural Water Association Training and Technical Assistance Program. Regionalization and consolidation of water system planning and operation is being encouraged both to realize economies of scale and to concentrate water supply talent. The development of junior college curricula in water treatment technology and water treatment instructor education is also being encouraged. State programs include innovative techniques for settling priorities and distributing available funds to water supply systems and acceptance of Primary Enforcement Responsibility, with attendant grant funds from EPA.

Detection of the particulate organic carbon of the plume and maximum oxygen demand would be restricted to the top 50 m of the surface layer within 15 km of the ship. Reduced oxygen concentrations in the benthic layer would be an undetectable consequence of the oxidation of the macerated and smothered bottom fauna.

Grob uses carbon disulfide to elute the organics off the activated carbon and gas chromatography to separate the organics in the eluent. The Grob CLSA method is a vapor-phase stripping method by which those compounds with appreciable vapor pressures over water are removed from the sample by purging it with a large volume of gas and passing the stripping gas through an adsorption tube. Unlike other vapor-phase methods, this method has achieved a millionfold concentration of most low and intermediate molecular weight organics by using a closed-loop design. In the process, 0.5 liter of stripping gas is recycled continuously through the water sample, and the adsorption trap is extracted with 10 microliters of carbon disulfide. Quantitative analysis is achieved by spiking the initial water sample with a series of internal standards, by stripping at 30 degrees for two hours, and by chromatographing the carbon disulfide extract on a WCOT (GC) column. The method may be employed for monitoring, for analytical steps in epidemiological studies, for granular activated carbon evaluation, and in recovery studies.

The study also aimed to identify treatment procedures and operational problems that might allow cysts to pass through filters and to discover the cyst removal capabilities of well-operated filters. The studies suggest, through the use of cyst models, that properly operated water filtration plants should remove a high percentage of Giardia lamblia cysts. In order for effective cyst removal to occur, diatomaceous earth filters need 1.0 kg sq m diatomite precoat plus body feed, and granular media filters need coagulation of raw water and production of filtered turbidity well below 1.0 normal turbidity units throughout the entire filter run.

General cost characteristics of chlorination and alternative methods of disinfection; a comparison of costs among disinfectants at presumed equivalent dosages; and a comparison of energy utilization among alternative disinfection processes are also discussed. A comparison is made of the costs and benefits associated with the alternative disinfectants on a common basis. The analysis presented is based on the records of the Cincinnati Water Works and the Hamilton County, Ohio Health Department. The study demonstrated that disinfection and the combination of disinfection and filtration are highly cost-effective preventive public health practices. When various disinfectants are compared on the basis of dosage and energy comsumption, chlorine is probably the cheapest disinfectant. In terms of incremental dosage, chlorine has the lowest marginal cost per unit increase in concentration. The costs of other disinfectants are only slightly higher, however, than that of chlorine, and disinfection on any basis shows a favorable cost-benefit relationship.

While the quality of urban stormwater varies greatly from metropolitan area to metropolitan area, the biochemical oxygen demand is close to that of secondary treatment plant effluent and the suspended solids concentration is similar to that of raw sanitary wastewater. Because there is high volume variability with stormwater and combined sewer overflow, physical treatment units are generally better than biological ones. A treatment system is designed with the final water quality desired in mind. The sample stormwater reclamation system included a storage reservoir and treatment facilities. Treatment included: fine mesh screening, chemical addition, high rate filtration, disinfection, and carbon columns. A system using a combination of city water and reclaimed stormwater would save approximately $900,000/year over a system using only city water. Reclaimed urban stormwater can be used for industrial subpotable water.

It includes the relationship of transmission costs to the problem of serving spatially distributed demand. It is possible to find a point at which the partial differential of the average cost function with respect to distance is zero, yielding a system size for minimum cost. Although the per capita consumption and absolute levels of population density have little effect on least cost system size, the minimum cost solution is very sensitive to population distribution. These insights can be used in planning water systems, especially regarding efficient utility size and alternatives for outlying areas.

AN - 74012022; 15622729 AB - The behavioral effects of both acute and subacute triethyltin (TET) exposure were examined in the rat. Animals acutely exposed to TET at doses of 0, 1.5 and 3.0 mg/kg showed a dose-related decrease in motor activity when tested between 2 and 4 hr following exposure. Subacute (3 week) exposure to TET in the drinking water (5 or 10 ppm) resulted in performance decrements in the following: maze activity, open field behavior, acoustic startle response and landing foot-spread. Early signs of behavioral deficits were observed 2 weeks after 10 ppm TET. These effects were reversible within one month after termination of exposure.

AN - 73960183; 15622726 AB - The activity of tyrosine hydroxylase (TH) was measured in homogenates of hypothalamic tissue and corpus striatum obtained from 24 day old rats. The addition of manganese to the preparations had no direct effect on TH activity in either brain region. Similarly, the addition of calcium, magnesium and lead at concentrations of 1.0 mM did not affect TH activity. Cadmium and zinc (1.0 mM) significantly reduced TH activity in both the hypothalamic area and corpus striatum. Iron (1.0 mM) significantly stimulated TH activity in the corpus striatum but did not affect TH activity in the hypothalamic area. At conentrations of 1.0 mM, neither disodium ethylenediamine tetra-acetic acid (EDTA) nor ethylene glycol bis (beta-amino-ethyl ether)-N,N'-tetraacetic acid (ECTA) affected directly TH activity in either brain region. Cyclic adenosine 3',5'-monophosphate (cAMP) at a concentration of 1.0 mM did not affect TH activity in either the hypothalamic area or corpus striatum. Results from these in vitro studies show clearly that manganese does not inhibit directly TH activity and that manganese does not compete with other physiologically important divalent cations to cause the reduction in TH activity seen in vivo after chronic exposure.

AN - 73921026; 15622725 AB - Male rats were exposed to manganese at doses of 1, 10, and 20 microg/g body weight/day from birth to day 24 post-partum. Animals were weighed and examined daily. The animals showed no visible signs of toxicity and exhibited normal weight gain. On day 25 the animals were killed by decapitation and the hypothalamic area and corpus striatum were removed and analyzed for several neurochemical components. Chronic manganese administration (10 and 20 microg/g) caused a significant reduction in the concentration of endogenous dopamine in the hypothalamic area. The concentration of endogenous norepinephrine in the hypothalamic area was unaffected at all levels of manganese administration. The depletion of dopamine induced by alpha-methyl-p-tyrosine was less in the hypothalamic area of chronic manganese-treated rats suggesting that dopamine turnover was reduced. No significant changes in neurochemical components occurred in the corpus striatum. Manganese at a dose of 20 microg/g caused a significant decrease in hypothalamic tyrosine hydroxylase activity and a significant increase in hypothalamic monoamine oxidase activity. The dosing regimen of 10 and 20 microg/g caused a significant elevation in tissue levels of manganese in both the hypothalamic area and corpus striatum. The results of this study indicate that minor alterations in the manganese content of the developing rat brain can lead to neurochemical alterations in specific brain regions.

Environmental factors seem to be the most important determinants of the initial population sizes. A general management strategy is proposed, which is consistent with the environmentally controlled occurrences of dominant year classes, and which also optimizes benefits from the fisheries. Because the relative importance of biological and abiotic population controls is uncertain, the proposed management strategy also strives to protect the reproductive potential of the striped bass stocks. This biologically based strategy can be implemented in the form of regulations that are flexible temporally and geographically.

Since 1970 the fastest population growth has been in rural areas, not in the cities. People are moving out of the largest cities in substantial numbers into counties with the lowest population densities. Rural planning capabilities and land use controls, where they exist, cannot anticipate or regulate the rapid pace of new development. Further, rural fiscal resources often cannot meet the demands for such public services as sewers, schools, medical facilities, police and fire protection, which are created by new residents. The many tasks confronting municipalities experiencing population increases include planning sewage treatment improvements - expansions or entirely new systems. One of the first tasks in the planning stage should be the development of a sludge management program. The end product of the wastewater treatment operation should be dealt with at the very beginning of the planning process. Municipal sludge treatment and handling should be an issue of public decision-making and should be brought out of the conference rooms of sanitary engineers and contractors who have been trained in designing and building bigger and better treatment systems. In these communities there have to be citizens trading ideas about what kind of future sludge management programs are best for their area.

EPA takes a great interest in the environmental implications of the manufacture of synthetic fuels , including coal liquefaction and gasification, retorting of oil shale, and the production of alcohol for fuel. Interest is also expressed in geothermal, solar, wind and tidal energy, combustion modification, coal and oil shale mining, energy conservation, fuel and energy transport and transmission, and new energy conversion systems such as ocean thermal gradients, magnetohydrodynamics, and fuel cells. In the area of pollution control guidance, the focal point of each regulation is intended to be a set of available control alternatives for each environmental discharge along with associated performance expectations and the basis for the alternatives presented. For most of the new energy technologies, exemplary full-scale and even pilot-scale waste treatment installations do not yet exist. A novel possibility now available is that of influencing in an environmentally productive way the choice by industry of the actual process technology to be commercialized and the overall designs of new plants, such that the most cost-effective environmental protection methods can be incorporated into the process design from the start. Specific energy technologies for which pollution control documents are now planned include low Btu coal gasification, indirect coal liquefaction, oil shale mining and processing, direct coal liquefaction, geothermal, medium Btu coal gasification, and high Btu coal gasification.

The application of ecological models to the Lake Michigan basin was the central focus of this research. A modified version of a deterministic phytoplankton mode, Lake 1 by Thomann, was first calibrated to the 1976 Lake Michigan field data. A dynamic phytoplankton simulation model (MICHI) was developed to investigate the observed field data and to use in forecasting lake responses to various phosphorus loading scenarios. The 1977 data indicated that the southern basin of Lake Michigan lost up to 3 micrograms of phosphorus per liter compared to concentrations observed in 1976. In an attempt to simulate this rapid depletion of phosphorus, MICHI required an implicit representation of suspected effects of an extensive ice cover observed during the winter of 1976-77. This included increasing the net apparent settling rate eight fold during ice cover. A total phosphorus model was used in conjunction with MICHI for forecasting. These forecasts indicate a steady-state total phosphorus concentration of 7 micrograms phosphorus per liter, given the target load recommended by the 1978 Water Quality Agreement. The projected time to obtain 95% of steady-state response to a load change was 7-14 years. (Baker-FRC) JF - Journal of Great Lakes Research Vol 7, No 4, p 467-480, 1981. 10 Fig, 3 Tab, 43 Ref.

The multi-class phytoplankton simulation model was set to field data acquired on Saginaw Bay, Lake Huron, during 1974. The concept of a single limiting factor for phytoplankton growth was found to be overly simplistic. Results indicated that temperature and light were relatively more growth rate limiting than nutrients on an annual average bases. However, as a consequence of nutrient depletion, nutrients became relatively more important at the times of peak phytoplankton crops. Nitrogen was more growth rate limiting than phosphorus to the total phytoplankton crop, although important differences occurred among the individual functional groups. While nitrogen and silicon were important in phytoplankton-nutrient dynamics, the supply of phosphorus would ultimately determine the size of the blue-green component of the total crop because nitrogen fixing blue-greens did not have absolute requirements for dissolved available nitrogen or silicon. Phosphorus requirements for summer crops were satisfied by recycle processes within the water column. Phytoplankton production was extremely sensitive to variation in the light extinction coefficient in the water column and relatively insensitive to variations in incident solar radiation.

Biodegradation of toxic chemical substances is best described by Grau kinetics. An estimate of mass transfer coefficients in air stripping can be obtained from the ratio of the diffusion coefficient, molecular weights, or critical volumes in conjunction with a known value of the mass transfer coefficient. Sludge adsorbs some priority pollutants, primarily polynuclear aromatic compounds, metals, and cyanides. The disappearance of a specific toxic pollutant in sludge in nonbiodegradable form can be represented by the multicomponent adsorption equation of Langmuir type based on the binary characterization of wastewater adsorption.

Viruses used were poliovirus (Sabin Type 1), coxsackievirus A9, and the f2 bacteriophage. Escherichia coli was treated under the same conditions as the virus--unadsorbed or adsorbed on 1 and 5 turbidity units (TU) of bentonite clay (particle size 3-8 mm), up to 0.53 mg per liter ozone, temperature 20 C, pH 7.0, and inactivation times of 10, 20, and 30 sec. Poliovirus, coxsackievirus, and E. coli associated with clay were inactivated at rates similar to the freely suspended organisms. The f2 bacteriophage was inactivated at a slightly slower rate than freely suspended phage. Typical results obtained were: 5 TU adsorbed poliovirus (140 plaque forming units (PFU) per ml), 0.016 mg per liter ozone, > 97% inactivated within 20 sec; 5 TU adsorbed coxsackievirus (220 PFU per ml), 0.019 mg per liter ozone, > 98% inactivated within 20 sec; 5 TU adsorbed f2 bacteriophage (15,000 PFU per ml), 0.061 mg per liter ozone, > 98% inactivated within 20 sec; 5 TU adsorbed E. coli (180 million CFU per ml), 0.038 mg per liter ozone, > 99% inactivated within 10 sec.

Data obtained from intensive pollutant sampling in the Grand River, flowing into Lake Michigan, were used as a comparison. On the basis of the root mean square error the best method was the unbiased stratified ratio estimator, recommended for use when concentration data are limited and daily river flow records are available. Other methods evaluated were five simple methods based on daily, monthly, quarterly, semiannual, and annual average concentrations. The complex methods generally were more adequate. These were based on concentrations from quarterly, semiannual, annual, and stratified regression on log flow. Accuracy was increased by including more samples from the high flow periods.

OWRT is charged with ' assuring an adequate supply of water of good quality for the nation 's needs through water-related research and practical application of R and D results. ' OWRT supports 54 water research centers and a focused research program; it also operates the Water Resources Scientific Information Center. Nonpoint pollution research is needed to identify the source, amount, and impacts of the pollutants entering our water resources from a variety of land use activities. A knowledge of the fate and cycling of nitrogen and phosphorus is needed along with more information about the fate and pathways of the over one billion pounds of pesticides manufactured in the United States every year. Other nonpoint pollution research areas include environment transport analysis, the limits of environmental protection, application methods, marshes and wetlands as barriers to contamination, erosion and sediment control, and acid rain. Research is the key to the solution of nonpoint pollution problems.

Disinfection rates are compared in terms of the times and concentrations required to achieve a specified degree of inactivation (e.g., 99%) of a given microorganism. Overall, ozone is the most efficient and least stable agent; chlorine dioxide is second in efficiency and stability; free chlorine is third in efficiency and stability, and chloramines are least efficient and most stable. Inactivation kinetics for E. coli, poliovirus 1, cell debris-associated poliovirus, and coliform bacteria are graphed for all the agents except ozone, which operates too quickly for convenient plotting. Ozone has been shown to effect greater than 99.999% reduction of E. coli in 10 sec at an initial concentration of 0.38 mg/l, and 99.7% reduction of poliovirus 1 in 10 sec at only 0.012 mg/l. The biocidal action of ozone and chloramines was only slightly affected by pH in the pH 6-9 range; that of chlorine declined rapidly as pH rose from 7-9, and that of chlorine dioxide rose as pH increased. The effects of particular microorganisms and dissolved salts on biocidal efficiency are also discussed. Laboratory studies simulating field conditions indicate that turbidity can shield microorganisms from disinfectants: e.g., viruses suspended with cell debris are protected from ozone. There is not yet sufficient information to recommend the replacement of chlorine with other disinfectants.

Data are being gathered from many sources to be used in a predictive model. Point source information from municipal and industrial sources is being synthesized from existing EPA and State and agency files. LANDSAT data will be used to perform land-use analyses to develop nonpoint source runoff projections. Fall line monitoring on the Susquehanna, Potomac, and James Rivers will provide data on suspended sediments, nutrients, metals, pesticides, fresh water discharge, and other physical and chemical parameters. Nonpoint monitoring programs are being conducted in the Occoquan and Ware River watersheds and in the Pequea Creek basin. The Hydrologic Simulation Program in Fortran has been selected for modeling of the non-tidal drainage basin of the Bay. Following verification of the model, it will be used to produce time series output of current and future loadings, land-use patterns, and input for a Bay-wide water quality model at the tidal Chesapeake.

Regulations finalized by EPA on November 29, 1979, set forth a maximum contaminant level of 0.10 mg/l for total THMs, and require monitoring and reporting of THM levels at quarterly intervals. Control strategies include use of a disinfectant that, unlike chlorine, does not generate THMs (chloramines, chlorine dioxide, ozone), reduction of THM precursors prior to chlorination, or reduction of THMs after formation. By 1977, ozone was the perferred disinfectant in more than 1039 water treatment plants, mostly in Canada and Europe. Ozone is a more effective disinfectant than chlorine, does not produce THMs, and can also be used to remove THM precursors prior to conventional chlorination. Precursors can be removed by direct ozonation or by using ozone to improve the removal efficiency of coagulation, settling, or filtration units. A summary of data from pilot studies showing THM precursor removal efficiencies of up to 80% is presented. Disadvantages of ozone compared to chlorine include limited residual disinfectant protection (sometimes leading to aftergrowth problems), higher costs, and the potential for forming organic byproducts with unknown health risks. Consideration of ozone 's ability to remove THM precursors while improving the efficiency of other unit processes is likely to reduce its price disadvantage.

New initiatives are being taken in this area by Congress, the Environmental Protection Agency (EPA), the Agriculture Department, the Department of Interior, and other Federal agencies. EPA 's Section 208 and its grant funds are aimed directly at nonpoint pollution with emphasis on urban runoff, agricultural runoff, and groundwater contamination. EPA has developed the National Urban Runoff Program to prepare a data base on the costs and impacts of urban runoff pollution and controls. Thirty prototype projects to test control methods are being supported by Section 208. Initial 208 plans indicate that agricultural runoff is the most widespread cause of nonpoint pollution. Government agencies are aiding farmers and ranchers in the implementation of best management practices. Groundwater protection research is being funded as part of the Water Quality Management Program. The understanding of a wide range of public agencies and public interest is needed for success in nonpoint pollution control.

These 21 impoundment sites were selected by the House Subcommittee as having a high potential for contaminating local ground-water resources, as they are located in close proximity to the tops of highly permeable aquifer systems, thus allowing leakage or direct infiltration of wastes into the ground water; the waste waters in these impoundments may contain chemical substances classified as hazardous; there are no artificially placed barriers or liners beneath these impoundments; the sites are within one mile of a potential water supply well; and a very small percentage of industrial impoundments nationwide are being monitored for ground-water quality effects. These 21 industrial complexes include chemical companies, steel corporations, asphalt companies, incineration plants, a scrap lead plant, and other industrial classifications. The results of individual studies conducted at each of the impoundment sites are presented.

A survey of 19 municipal and 17 recreational package water treatment systems produced the following performance data: pH, 6.5-8.6; coliforms, present in 3 of 31 systems; turbidity, 8 of 31 exceeding maximum federal standards; trihalomethanes, 5 of 31 exceeding 0.10 mg per liter; pesticides, none; silver, 2 systems; mercury, less than 0.001 mg per liter in several plants and 0.020 mg per liter in 1 municipal plant. Most aberrations in performance were ascribed to operator inattention or intermittent operation. Most package plants serve populations of 10,000 or less and have a capacity of 1.5 mgd or less. Comparative costs of a 1 million gallon per day conventional plant versus a package plant showed that the package plant was more economical. Construction costs for a conventional plant were $1,120,000 and annual operating and maintenance costs, $63 ,000; package plant, $488,000 and $40,000 respectively.

The procedure uses purge- and trap sample concentration followed by GC/MS analysis. Data reduction is performed by a computerized GC/MS data system. The quantification limits, precision and accuracy of these analyses have been demonstrated to be comparable to gas chromatography coupled with electrolytic conductivity and flame ionization detection. The analytical scheme permits the routine qualitative and quantitative analysis of 16 commonly occurring purgeable compounds over a concentration range of 0.1-0.2 to 0.5 micrograms/liter. Additional compounds can be analyzed by incorporating appropriate analytical standards.

Samples were analyzed for total organic carbon (TOC) using the Dohrmann TOC system. Three analyses were conducted for purgeable halogenated organics: instantaneous trihalomethanes (THM), simulated distribution THM, and THM formation potential. Response profiles from capillary column gas chromatographic analysis of influent and effluent samples from operating GAC beds were used to qualitatively judge adsorber performance. TOC results can serve as an operating guide at a given location if proper relationships can be established with TOC levels and concentrations of other substances. GAC reduced the simulated distribution THM concentrations and organic halogen levels, but the performance of the GAC system varied with changing influent conditions. Other drawbacks of the organic analysis of GAC performance include the requirement for subjective interpretation of some outputs and difficulties in managing large amounts of data.

In 1977, the Office of Water Research and Technology (OWRT) of the U.S. initiated its Water Reuse Research and Development Program by conducting a comprehensive national analysis of reuse and potential throughout the U.S. This study indicated that a high potential for both municipal reuse and industrial recycling exists in the U.S. The OWRT also evaluated existing treatment technology for applicability in reuse systems. The role of state agencies in implementing an effective wastewater reuse research program includes determining wastewater reclamation research needs, assessing the status of world-wide wastewater reclamation research, establishing a list of high priority research areas for funding priority, and working cooperatively with federal agencies involved in water reuse. Projects involving beneficial reuse of wastewaters that result in reduction of wastewater discharges and utilization of nutrients, organic materials or pollutants should merit funding support at least equally with single purpose pollution abatement projects.

An inert gas is bubbled through the sample. Those organohalides and other organic constituents which boil at less than 200 degrees C, are removed from the aqueous phase and trapped in a short column containing a sorbant combination. After a predetermined time, the trapped components are thermally desorbed, backflushed onto the head of a gas chromatograph and separated under programmed conditions. Measurement is done with a halogen-specific detector. The method is useful for determination of carbon tetrachloride, 1,2-dichloroethane, tetrachloroethylene, 1,1 ,1-trichloroethane, trichloroethylene, vinyl chloride, and 44 additional halogenated compounds listed in a table. The method, useful for detection and measurement of multicomponent mixtures spiked into carbon filtered finished water and raw source water at concentrations of 0.20-0.40 micrograms per liter, has detection limits of < 0.01 micrograms per liter. The compounds listed in the table can be accurately measured over a concentration range of 0.10-5.0 micrograms per liter. Individual organohalides can be determined at concentrations up to 1500 micrograms per liter. JF - EPA Report No. 600/4-81-059 1981. 50 p, 7 Fig, 4 Tab, 3 Ref.

The wastewater samples are screened for organics by analyses of five fractions: pesticides (26 compounds), base/neutrals (46 compounds), acids (11 phenols), purgeables (29 volatile organics), and direct aqueous injection (2 compounds). Except for purgeable organics, overall recovery decreases and the relative standard deviation increases in going from the method standard to the matrix spiked analysis. Analysis of purgeable and acid organic compounds produces the highest recoveries with the smallest matrix effect. The analysis of base/neutral compounds and pesticides gives the lowest recoveries because they react among each other and with hydroxide and water. Base/neutral compounds also carry over into the acid fraction in the presence of emulsions. Analysis of purgeable organics by the EPA protocol has been most successful; acid and pesticide analyses, moderately successful; and base/neutral analysis less successful, especially with samples from the leather tanning and timber industries. Metals analyses are not difficult at the 25 ppb level used. Analyses of several compounds presented problems and are recommended for further investigation: dichloromethane, bis(chloromethyl) ether, N-nitrosodimethylamine, di-n-butylphthalate, bis(2-ethylhexyl) phthalate, 1,2-diphenylhydrazine, benzidine, hexachlorocyclopentadine, endrin aldehyde, anthrene and phenanthrene, chrysene and benzo(a)anthracene, and benzo(b)fluoranthrene and benzo(k)fluoranthrene.

AN - 15553756; 402872 AB - Since arsenic is a significant compound of ores processed in the nonferrous metals industry, it is of interest to characterize and evaluate control strategies which have demonstrated the potential for lowering the emission rates of arsenic and other hazardous effluents from smelter operations. The Campbell Red Lake Mines Gold Smelter at Balmerton, Ontario, Canada, has developed and implemented a successful control strategy for arsenic emissions from a nonferrous smelting operation. The control system was designed and installed by Hatch Associates, Toronto, Canada. The Red Lake smelter uses cyclones and a hot electrostatic precipitator to recover metal values from roaster dusts with subsequent air quenching to condense (or desublime) arsenic trioxide which is recovered in a low-temperature baghouse. This paper is a review of a test program conducted at Red Lake designed to characterize the control systems and to evaluate the potential for transferring the technology to smelting operations in the United States.

AN - 15542767; 396524 AB - A 566 m super(3)/m permanent installation demonstration system, consisting of the Air Pollution Systems' High Intensity Ionizer and a variable throat venturi scrubber has been installed on a magnesium recovery furnace. The furnace produces submicron fume particles of MgO, MgCl sub(2), and ZrCl sub(4). The system is designed to demonstrate the effectiveness of the High Intensity Ionizer versus high venturi pressure drop on the furnace emissions. The High Intensity Ionizer array operates stably at field strengths of 10-15 kV/cm and at velocities in excess of 18 m/sec while maintaining high charging efficiencies. The report covers the system design, technology, applications, and project developments. An Environmental Protection Agency proposed charged droplet Scrub-E is also discussed covering the design, technology, and proposed demonstration program.

AN - 15518031; 349201 AB - Accurate estimates of pollutant loadings to the Great Lakes are required for trend detection, model development, and planning. On many major rivers, infrequent sampling of most pollutants makes these estimates difficult. However, most large rivers have complete daily flow records available from the U.S. Geological Survey. A number of different estimation methods have been developed to use these data in conjunction with available concentration data to calculate pollutant loadings. Several of these methods have been evaluated in this paper for a typical major tributary. Intensive measurements of pollutant loadings to Lake Michigan from the Grand River in 1976-1977 were conducted by USEPA, Region V. Daily concentrations of several chemical parameters, including total phosphorus, were determined. This information, together with daily river flow rates from USGS, provide an excellent data set for testing various load estimation methods. Ten different methods were tested using 680 randomly generated 25-sample subsets of the daily total phosphorus data set. The methods tested included several simple calculation schemes, as well as flow-concentration correlations and the stratified ratio estimator. The latter method is shown to be at least slightly better than the others for these data and for this type of sampling, including when sampling is concentrated during periods of high flow.

AN - 15497616; 321674 AB - The Clean Air Act, as amended in 1977, requires periodic review and revision of all national ambient air quality standards (NAAQS) to insure that they are based on the latest scientific information. A possible framework for analyzing health risks associated with attainment of alternative NAAQS is described. The framework consists of three phases of analysis for supporting future regulatory decisions on NAAQS: (1) a scientific assessment phase, (2) a risk assessment phase, and (3) a risk evaluation and decision analyses phase. The proper separation of roles among scientists, risk analysts, and decision analysts is also addressed. The author concludes that despite several possible pitfalls, the adoption of formal risk analysis approaches can greatly facilitate communication between scientists and decision makers and decision makers and the public in areas involving scientific uncertainties.

AN - 15496353; 327952 AB - The National Park Service and the U.S. Environmental Protection Agency are cooperatively conducting ongoing studies of human perception of visual air quality. Major objectives of this program include: (1) determination of the relationship between judgments of visual air quality of actual three dimensional scenes and a surrogate slide representation of that scene, (2) examination of the effect of sun angle and meteorological conditions on perceived visual air quality, (3) examination of the effect of demographic background on observer's judgments of visual air quality, (4) establishment of a functional relationship between human perception of visual air quality and various electro-optical parameters for several different scenic vistas and (5) development of a model capable of predicting the sensitivity of a park to visual air pollution impact. Preliminary results of a previous study involving one vista revealed a linear relationship between human perception and apparent vista contrast for constant vista illumination and ground cover. A more general formalism for averaging vista color contrast appeared to account for effects that snow cover and varying illumination have on the sensitivity of perceived visual air quality to air pollution.

AN - 15488145; 294887 AB - This paper evaluates from an ex post perspective the economic viability of a pilot irrigation project in northern Senegal which has been in operation since mid-1975. The authors begin by presenting the international context within which the Nianga Project developed, namely, the donor agencies were called upon to fund additional tertiary (i.e., full water control) irrigation projects in the Senegal River Valley in the absence of any rigorous economic analysis of this type of irrigation project. Next, they briefly describe first the project milieu and then the development and operation of the project itself. From the descriptive they pass to the analytic mode, wherein the project is formally evaluated with the techniques of social cost benefit analysis (SCB); and subsequently, they compare the ex ante feasibility study and the present ex post analysis. Finally, on the basis of the results from the latter, they draw some policy implications for future irrigation development in the Senegal River Valley. JF - J. DEVELOP. AREAS.

AN - 15484325; 294886 AB - In discussing an approach to assessing the health risks that would obtain if various possible primary national ambient air quality standards were met, it is important to distinguish appropriate principles for probabilistic risk assessments from principles for the scientific research and scientific assessments on which they are based. Appropriate principles for probabilistic assessment are derived from the ultimate objective of maximizing the amount of control societal decision-making agents have in making environmental trade-offs under uncertainty about the effect of their decisions. A general methodology is presented which implements these first principles. Two general risk models are presented: a relatively simple benchmark risk model and a more complex head count risk model. These general risk models serve as a guide for the development of specific operational risk models applicable to particular ambient pollutants. Examples are given of different specific models needed for different types of pollutants. Since the scale on which a specific methodology is implemented is not determined by the methodology, the various choices involved in deciding the scale of a specific application are addressed.

AN - 15464158; 271221 AB - EPA's airborne downlooking dye lidar was operated during the STATE field program in western Kentucky/Tennessee in the summer of 1978. In this paper, lidar estimates of height of the atmospheric mixing layer are shown and compared with in situ measurements. Lidar estimates of crosswind and vertical dimensions of TVA power plant plumes are compared with appropriate literature values and with in situ estimates from data compiled by other STATE investigators; wherever necessary, data are adjusted to ensure compatibility with respect to sampling time.In addition, lidar measurements of plume rise are compared with model calculations. The lidar estimates of mixing layer height were usually slightly higher than in situ counterparts, presumably because aerosols may rise and become trapped above the base of the elevated stable layer. Values of plume rise computed using the Briggs models were generally similar to those indicated from lidar measurements although considerable scattering of data existed; supplementary data indicated that the scatter could be reduced with the inclusion of the vertical shear of the horizontal wind in the models.

AN - 15453791; 268587 AB - N-Methyl-4-aminoazobenzene (MAB) is believed to be metabolized in the liver to an electrophilic N-sulfonyloxy ester which binds covalently to cellular macromolecules, resulting in the induction of hepatic neoplasia. Since a single dose of MAB is not sufficient for complete carcinogenic activity, the authors sought to identify the MAB-DNA adducts present in rat liver after multiple oral doses of ( super(3)H) MAB. The MAB was administered by intubation at a level of 0.2 mmol/kg for 1, 3 or 4 doses and animals were sacrificed at 8 h after the last dose. Hepatic DNA was isolated by extraction and hydroxylapatite chromatography and was enzymatically hydrolyzed to MAB-mononucleoside adducts, which were quantitated by high pressure liquid chromatography (HPLC).

AN - 15447489; 251898 AB - The reductive dechlorination of dieldrin and endrin was investigated as a possible procedure for field disposal of small quantities of these pesticides. The objective was to convert the parent compounds to environmentally less objectionable materials. Emulsifiable concentrate formulations of the pesticides in a soil slurry were mixed with powdered zinc, dilute acetic acid, and acetone to facilitate reaction. Analysis of the mixtures by GC-MS indicated essentially complete conversion of endrin and partial conversion of dieldrin to products probably formed by replacement of the bridge anti chlorines with hydrogen. Partial confirmation of the desired anti dechlorodieldrin product was made by nmr. Disappearance of the parent compounds and production of conversion products was monitored for 1 1/2 years by GC in an outside soil plot, and accelerated destruction of parent compounds was achieved by the treatment. By analogy to the bridge anti dechloro products of aldrin and isodrin, the anti dechloro products probably are much less toxic than the parent compounds and are therefore environmentally less objectionable.

AN - 15432323; 250692 AB - The U.S. Environmental Protection Agency, National Park Service, Visibility Research Center, and University of California at Davis are currently operating a monitoring program in national parks and monuments throughout much of the western United States. Project VIEW, the Visibility Investigative Experiment in the West, includes measurement of visibility parameters using manual telephotometers, and measurement of particle concentrations averaged over 72 h. Variation of these parameters occurs in both space and time. To better understand these variations, several techniques including principal component analysis and data comparisons among sites are applied to Fall, 1979 data for much of the network. Then the Grand Canyon is chosen for additional analysis. Best and worst case visibility days are determined and compared with particle concentrations. Finally, hypothetical causes for visibility reduction are further verified by computing wind trajectories back in time for these special case days.

AN - 15430289; 236751 AB - This study was designed to assess the effects of diesel exhaust on the development of the nervous system in rats as measured by somatosensory and visual evoked potentials (SEPs and VEPs, respectively). SEPs, elicited by 1 mamp, 0.5 msec pulses delivered to the tibial nerve at the tibale, were recorded from the skull overlying the somatosensory projection area on days 28, 35, 42, and 49 postconception (pc). Analysis of the data for day 35 pc double pulse SEPs revealed significantly longer latencies for all peaks of the SEP in pups exposed to diesel exhaust. There were also differences indicating that the electrophysiological recoverability of the nervous system had been compromised in the diesel exhaust exposed group. On day 35 pc, the latencies of all VEP peaks occurring before 300 msec were greater in the exposed group. The differences, however, reached statistical significance only for the P2 peak of the response to the first of the paired stimuli. These data support the hypothesis that diesel exhaust influences the development of the nervous system. JF - Environment International AU - Laurie, R D AU - Boyes, W K AD - Health Effects Res.

AN - 15429490; 243769 AB - Eight food-deprived rates were trained to perform under a schedule that arranged milk reinforcement after every 10 (N=4) or 40 (N=4) lever preses. Baseline control performance for all rats was characterized by a brief pause in responding after milk delivery, followed by a rapid rate of responding that was maintained until the next milk delivery. Chlordimeform HCI (CDMF) produced dose-related decreases in response rat and increases in pause duration when 1.25-40 mg/kg bodyweight was given IP,10 min pre-session. Dosages estimated to produce a 50% decrease in overall responding were between 5 and 10 mg/kg for rats performing under either response requirement. Similar effects on performance were obtained when 5 mg/kg CDMF was given 10 and 50 min pre-session, and when 10 mg/kg was given 10, 50, and 120 min pre-session. The effect of 5 mg/kg CDMF (10 min pre-session) was not consistently modified by prior monoamine oxidase inhibition with pargyline HCI (20 or 50 mg/kg, 60 min pre-session). CDMF (10mg/kg) also decreased the rate at which rats (N=5) responded, and increased the rate of shock delivery, under a signaled shock avoidance paradigm. JF - NEUROBEHAV. TOXICOL. TERATOL.

AN - 15428894; 243462 AB - Polychlorinated biphenyls (PCBs) have been recognized as environmental contaminants since the mid-1960s. Until recently, however, little work has been done on identifying levels of PCBs in the indoor air. This paper describes a method for the analysis of PCBs utilizing low-volume indoor air sampling. The method uses polyurethane foam as a collector and has a limit of detection of similar to 0.01 mu g/m super(3). This study shows that indoor air, whether in commercial, industrial, or residential buildings, contains levels of PCBs at least 1 order of magnitude higher than outdoor levels. Defective fluorescent light ballasts are also shown to emit PCBs and to be an important source of indoor atmospheric contamination. JF - Environmental Science & Technology AU - MacLeod, KE AD - Anal.

AN - 15423899; 234520 AB - Adult male, inbred, disease-free cats of uniform age and size were exposed eight hours per day, seven days per week to a 1:18 dilution of diesel exhaust emissions. After one year of exposure, the animals were removed from the chambers for measurement of lung volumes, forced expiratory flow rates, dynamic compliance and resistance, diffusing capacity, and nitrogen washout. No important changes in pulmonary function were detected with the exception of a decrease in closing volume (P<0.05). The inability to detect decrements in pulmonary function may have been due to insufficient concentration of exhaust, insufficient exposure length, or to the use of a species resistant to diesel exhaust. To test these possibilities, the cats are being exposed for an additional year, and another species, hamsters, are being exposed for future testing at exhaust dilutions of 1:18 and 1:9.

It has low solubility in seawater (24 mu g/L), strongly adsorbs to sediment and particulate matter in water, has a half-life of 24 days in estuarine sediment in laboratory systems. Acute toxicity tests conducted at the Gulf Breeze Environmental Research Laboratory indicated that fenvalerate was extremely toxic to various aquatic organisms: mysid shrimp (Mysidopsis bahia ), pink shrimp (Penaeus duorarum ), four species of fish (Mugil cephalus, Menidia menidia, Opsanus beta , and Cyprinodon variegatus ), lobster (Homarus americanus ), sand shrimp (Crangon septemspinosa ).

The effect of pretreatment on the excretion of radioactivity and the distribution of eight lindane metabolites was examined. Even though the rate of lindane metabolism was unchanged by the beta -naphthoflavone pretreatment, results of the study indicated that all three pretreatments significantly altered lindane metabolism. The pretreatments differed from one another in that they selectively altered specific metabolic pathways.

AN - 15410095; 234774 AB - In the initiation/promotion assay in rat liver, partial hepatectomy is used to enhance initiation, and a choline-devoid diet as promoter. The induction of carcinogenesis is determined by the focal appearance of gamma glutamyl transpeptidase (GGT) positive hepatocytes. The authors adopted this assay to diesel exhaust emission by performing a 2/3 partial hepatectomy, and exposing the rats to either clean air or diesel exhaust emission. The rats were fed either a choline-devoid or a choline-supplemented diet for three or six months. The animals were sacrificed and liver sections stained for GGT were examined for the presence of foci of GGT(+) hepatocytes. The results indicate that diesel exhaust exposure does not result in a systemic dose of carcinogens sufficient to be detected in the liver foci assay.

AN - 15402709; 218260 AB - A series of experiments was conducted in which groups of mice were first exposed for various durations to diluted exhaust from light duty diesel engines and then briefly to an infectious aerosol generated by nebulizing cultures of a bacterial pathogen (Streptococcus ). Typically, postinfection mortality was signigicantly greater in groups exposed to exhaust than in their corresponding control groups exposed to purified air only. Data of recent diesel and of past diesel- and catalyst-treated gasoline engine exhaust experiments suggest a somewhat grreater excess mortality from (enhanced susceptibility to) bacterial infection in mice exposed to diesel exhaust than in those exposed to catalytic gasoline exhaust. Limited data on acute tests of NO sub(2) and acrolein vapor alone suggest that the infectivity-enhancing effect of diesel exhaust could be accounted for in large part by these components. Exposures to diesel exhaust, NO sub(2), or acrolein did not enhance the mortality response to a viral pathogen (A/PR8-34).

AN - 15400221; 218303 AB - An intensive survey of water quality parameters was conducted on Lake Michigan during 1976 and 1977. A dynamic phytoplankton simulation model (MICH1) was developed to investigate the observed field data and to use in forecasting lake responses to various phosphorus loading scenarios. The 1977 data indicated that the southern basin of Lake Michigan lost up to 3 mu g P/L compared to concentrations observed in 1976. In an attempt to simulate this rapid depletion of phosphorus, MICHI1 required an implicit representation of suspected effects of an extensive ice cover observed during the winter of 1976-77. This included increasing the net apparent settling rate eight fold during ice cover. A total phosphorus model (TPM) was used in conjunction with MICH1; for forecasting. These forecasts indicate a steady-state total phosphorus concentration of 7 mu g P/L, given a target load recommended by the 1978 Water Quality Agreement. The projected time to obtain 95% of steady-state response to a load change was 7-14 years. JF - Journal of Great Lakes Research AU - Rodgers, P AU - Salisbury, D AD - EPA Large Lakes Res.

AN - 15398191; 213639 AB - The proposed conversion from gasoline powered automobiles to diesel powered vehicles has prompted the Environmental Protection Agency to evaluate the potential health effects associated with exposure to diesel emissions. At present, there is no direct epidemiological link between this exposure and human health. Therefore, a research program was constructed to compare the health effects associated with diesel emissions with those from other emission sources for which epidemiological information was available. The emission sources chosen chosen were cigarette smoke, roofing tar, and coke oven. An additional comparative emission source which was evaluated, was a gasoline catalyst engie. Respirable particles from a variety of combustion sources have the potential of being carcinogenic and mutagenic. The objective of these studies was to determine the relative biological activity of the organic material adsorbed on these particles in both in vitro mutagenesis and in vitro and in vivo carcinogenesis bioassays.

AN - 15395407; 215420 AB - Data in twelve power plant and smelter plumes reported by eight different organizations have been reviewed in an attempt to establish the existence of recognizable patterns concerning the extent and rates of sulfate formation. The data reviewed here were collected in Australia, Canada and the U.S., during warm as well as cold seasons, and during day and night. The primary variables examined and compared are S sub(p)/S sub(T), the particulate fraction of excess sulfur sampled in the plume, and the corresponding plume age. The variation of the extent of sulfate formation (S sub(p)/S sub(T)) is also examined in terms of plume exposure to solar radiation dose during transport. In spite of wide geographical, seasonal, background and source variations, a distinct difference is observed in day and night sulfate formation. During the daytime, there exists a substantial variability in sulfate formation rates (typically 0-5%h super(-1)) and extent (typically up to 25%) for any given physical plume age. This variability is significantly less for plumes with similar exposure to sunlight dose, showing that environmental factors linked to solar radiation strongly influence the rate and extent of sulfate formation in point-source plumes.

AN - 15395398; 213718 AB - The intraperitoneal injection of 5-hydroxytryptamine (5-HT) in unrestrained and unanesthetized mice held at 22 degree C causes a hypothermia which is maximal after approximately 15 min. When mice injected with 5-HT were held in a controlled environment of 22 degree C and 50% relative humidity and exposed to microwaves (2450 MHz, cw) at 1 mW/cm super(2) for 15 min, significant increases were observed in the body temperature of these mice compared to 5-HT-treated sham-irradiated mice. The magnitude of the response was related to power density (10 > 5 > 1 mW/cm super(2))/. Saline-injected mice exposed for 15 min at 10 mW/cm super(2) (specific absorption rate = 7.2 mW/g) showed no significant increase in body temperature compared to saline-injected sham-irradiated mice.

AN - 15391708; 214155 AB - Female Swiss mice were exposed 8 h/day to diesel exhaust for 1, 3, and 7 weeks. Urine was collected overnight for 4 days prior to sacrifice while the mice continued to be exposed for eight hours during the day. The presence of mutagens was determined by the Ames Salmonella test. One hour prior to sacrifice each mouse received 1 mg/kg colcemide. After sacrifice, the marrow from each femur was obtained. The marrow from one femur was used to prepare slides for metaphase analysis and the other for micronuclei assay. Other mice received IP 50 mg/kg cyclophosphamide 24 h prior to sacrifice or 1 mu mole/kg benzo(a)pyrene in each of four daily doses prior to sacrifice and served as positive controls. The Ames Salmonella assay of the unconcentrated urine after 1, 3, and 7 weeks and concentrated urine after 7 weeks exposure to diesel exhaust did not significantly vary from clean air controls. In the micronucleus test, and metaphase analysis, cyclophosphamide produced a strong positive response and the 7 week diesel exposure was not different from clean air controls.

The animals were kept in specially constructed inhalation chambers and exposed to clean air or diesel exhaust for eight hours daily. The animals were sacrificed and slides prepared to study the mutagenic effects of diesel exhaust by four in vivo short term mammalian bioassays. Sperm morphology bioassay revealed a 2.67-fold increase in sperm abnormalities in the animals exposed to diesel exhaust as compared to those exposed to fresh air. Micronucleus bioassay revealed a 50% increase in the number of micronuclei in polychromatic erythrocytes obtained from animals exposed to diesel exhaust. However, no increase in sister chromatid exchange or chromosomal abnormalities was observed in bone marrow cells of animals treated with diesel exhaust. During these studies a decrease in mitotic index was observed in animals treated with diesel exhaust.

AN - 15388184; 213159 AB - It is the major intent of this report to examine the animal inhalation facilities at the EPA Health Effects Research Laboratory in Cincinnati, Ohio, associated with the exposure to the exhaust of diesel-powered equipment. The facility serves as a center for toxicologic evaluation, in relevant animal models, of potentially hazardous environmental pollutants from diesel engine exhaust. Briefly, the entire engine exhaust is mixed with filtered and conditioned air in a dilution tube. That diluted exhaust enters a large volume mixing chamber and a portion passes through dynamic flow irradiation chambers (to simulate sunlight) and is then conducted to animal exposure chambers. The system provides nonirradiated exhaust in the same concentration (directly from the mixing chamber) and also filtered, conditioned ambient air for control animal exposure. The major physical components of the diesel emission system include: air purifiers, animal exposure chambers, engine-dynamometers, irradiation chambers, monitoring instrumentation and data acquisition systems.

AN - 15388110; 213257 AB - The biochemical response to controlled exposures of nitrogen dioxide (NO sub(2)) was studied in 19 human subjects exposed to 0.2 ppm NO sub(2) for 2 hr and compared to 15 control subjects exposed to filtered air for 2 hr. Seven biochemical blood parameters, including glutathione, red blood cell glutathione reductase, 2,3-diphosphoglycerate, methemoglobin, vitamin E, complement C sub(3), and IgA were measured prior to exposure, immediately after exposure, and 22 hr following exposure. The only variable that showed significant change due to NO sub(2) exposure was glutathione. Glutathione is known to protect the erythrocyte from oxidative stress. The increase in glutathione observed upon exposure to NO sub(2) may be a protective reaction of the erythrocyte to meet the oxidative stress. JF - ARCHIVES ENVIRON. HEALTH.

AN - 15385930; 215054 AB - Due to the expected increase in the percentage of diesel vehicles in the United States, the Environmental Protection Agency must evaluate the health effects associated with exposure to diesel emissions. Respirable particles from a variety of combustion sources have the potential of being carcinogenic and mutagenic. The objective of these studies was to determine the relative biological activity of the organic material adsorbed on these particles in in vitro mutagenesis bioassays. The organic extracts from the following series of emission sources were bioassayed in the Salmonella assay for mutagenic activity: (1) a light-duty Oldsmobile diesel 350 engine; (2) a heavy-duty Caterpillar diesel engine; (3) a light-duty Nissan engine; (4) a Volkswagen Rabbit diesel engine; (5) cigarette smoke; (6) roofing tar; (7) coke oven; and (8) a gasoline catalyst Mustang. This paper provides a comparison of these sources within the Salmonella bioassay and also demonstrates how bacterial systems can be used as a quality assurance measure in in vivo testing.

AN - 15374616; 197492 AB - The disposition of super(14)C-labeled methylparathion, parathion, and p-nitrophenol applied as a foliar spray was examined in the Terrestrial Microcosm Chamber (TMC) and compared to a reference compound, dieldrin. The impact of soil type (synthetic vs. natural) and airflow rates through the chamber on methylparathion disposition was evaluated. The TMC contained either a synthetic soil medium or Willamette sandy loam soil plus agricultural crops, numerous invertebrates, and a gravid gray-tailed vole (Microtus canicaudus ). Dieldrin was accumulated to a lesser extent than any of the organophosphates in the synthetic soil. Concentrations of methylparathion in the upper layer of Willamette sandy loam soil were consistently lower than those observed with the synthetic medium. Increased airflows altered methylparathion distribution primarily through increased export from the TMC. Although recovery of dieldrin was lower than with equivalent applications of organophosphates, a significantly greater concentration was detected in the vole. Only dieldrin appeared to affect vole survival. JF - Journal of Agricultural and Food Chemistry AU - Gile, J D AU - Gillett, J W AD - Terrestrial Div., Corvallis Environ. Res.

AN - 15371606; 198213 AB - The persistence and disappearance (washoff or dryfall) of methoxychlor (2,2-bis(p-methozyphenyl)-1,1,1-trichloroethane) from mature soybean (Glycine max (L.) Merrill) foliage was investigated in a small field plot study under natural rainfall conditions in 1977 and 1978. Residue analyses were conducted using whole plant samples. The amount of dryfall was significantly greater in plots entered by workers than in those where entry was avoided. Statistical analyses indicated that within-sample variation for mechanical chopping of plant samples was significantly smaller at the 5% level than for a hand chopping method. Results from this study will be useful in defining research objectives for the development of algorithms to describe the behavior of foliar-applied compounds. Such algorithms are necessary for estimating runoff losses of insecticides to water bodies. JF - J. ENVIRON. SCI. HEALTH.

AN - 15369938; 197646 AB - Before development of an emission standard for vinyl chloride, the Environmental Protection Agency (EPA) conducted three programs to measure vinyl chloride (VC) concentrations in air around plants which either manufacture VC or use it. A brief monitoring survey conducted by EPA Regional Offices found VC in ambient air around poly(vinyl chloride) (PVC) production plants. As a consequence of this survey, a second monitoring program was established to measure VC in the air around VC and PVC production plants. This program found some relatively high concentrations of VC in ambient air around the plants. This program found maximum 24-hr average concentrations ranging from 0.32 to 10.6 parts of VC per million parts of air. The program also found an apparent relationship between certain emission excursions and ambient VC concentrations. A third monitoring program was established to measure VC around PVC fabrication plants. This monitoring program found much less VC around PVC fabrication plants than around VC and PVC production plants.

AN - 15369398; 197721 AB - In regulation of exposures to hazardous environmental agents, epidemiologic evidence is especially important in defining human risk estimates. The process of developing appropriate regulations is complex, however, and depends on many considerations beyond those established to a high degree of scientific certainty. Thus the needs of regulatory agencies are involved in the way epidemiologic data are developed and presented. To coordinate and review common problems associated with preventive and regulatory activities among the federal agencies concerned with regulation, and Interagency Regulatory Liaison Group (IRLG) was established in 1977. Because of difficulties encountered by these agencies or Congressional committees in evaluating epidemiologic evidence, a subcommittee of the IRLG has developed in draft form guidelines for human population studies to be used in public health decision-making. Although these guidelines have attracted much controversy, their aim is to present criteria for design and documentation of epidemiologic studies, without interfering with the initiative of investigators.

AN - 15366523; 198116 AB - This study was designed to reveal patterns of response of major United States crops to sulfuric acid rain. Potted plants were grown in field chambers and exposed to simulated sulfuric acid rain (pH 3.0, 3.5 or 4.0) or to a control rain (pH 5.6). At harvest, the weights of the marketable portion, total aboveground portion and roots were determined for 28 crops. Of these, marketable yield production was inhibited for 5 crops (radish, beet, carrot, mustard greens, broccoli), stimulated for 6 crops (tomato, green pepper, strawberry, alfalfa, orchardgrass, timothy), and ambiguously affected for 1 crop (potato). In addition, stem and leaf production of sweet corn was stimulated. Visible injury of tomatoes might have decreased their marketability. No statistically significant effects on yield were observed for the other 15 crops. The results suggest that the likelihood of yield being affected by acid rain depends on the part of the plant utilized, as well as on species. Effects on the aboveground portion of crops and on roots are also presented. JF - ENVIRON. & EXPER. BOTANY.

The initial evaluation of this test system was accomplished using cadmium chloride, chromium chloride, cobalt chloride, mercuric chloride, nickelous chloride, sodium arsenite, sodium selenite, and ammonium vanadate. The relative toxicity of the compounds was as follows: Cd > V = As > Se > Hg > Cr = Co > Ni. Since several of the compounds with very similar EC sub(50)s had significantly different dose response slopes, an additional parameter, lowest effective concentration tested (LECT) was employed to assess the relative toxicity. The LECT was determined using the Williams test and the relative toxicity of the compounds was found to be Cd = Se > V > As = Hg > Co > Cr = Ni. JF - IN VITRO, J. TISSUE CULT. ASSOC.

AN - 15351917; 173160 AB - The effects of ozone (O sub(3)) on cell-mediated immunity were studied in 16 human subjects exposed to 1176 mu g/m super(3) O sub(3) (0.6 ppm) for 2 hr in an environmentally controlled exposure chamber. Venous blood samples were taken before and immediately after controlled air and O sub(3) exposures, as well as at 72 hr, 2 and 4 weeks, and at one random time at least 1 month after treatment. No statistically significant changes were observed in the number of T lymphocytes that form spontaneous rosettes with sheep erythrocytes. The response of T lymphocytes to PHA was significantly reduced in samples taken at 2 and 4 weeks following O sub(3) exposure. Normal response to PHA was observed at 2 months post-O sub(3) exposure. No statistically significant changes in lymphocyte responses to Con A, PWM, or Candida) were seen. These results show that one 2 hr exposure of humans to 0.6 ppm O sub(3) may lead to a transient suppression of the PHA-stimulated blastogenic transformation of peripheral blood lymphocytes. The data indicate that the blastogenic response to PHA of human lymphocytes is exquisitely sensitive to O sub(3) exposure and could serve as a bioassay for evaluating subtle changes in cellular immunity induced by O sub(3) and possible other pollutants.

AN - 15346758; 166192 AB - For a bimodal size distribution of ambient aerosol the upper particle size limit of the fine aerosol fraction can be chosen in such a way that the extinction coefficient for light scattering and absorption is directly proportional to the fine mass concentration, regardless of the magnitude of the coarse mass concentration. With the size parameters of the modes taken to be the "grand average continental" values of Whitby, the upper size limit is 3.4 mu m (aerodynamic diameter).

AN - 15346261; 166317 AB - Extensive research has determined that adipic acid, when used as an additive to a limestone flue gas desulfurizaiton (FGD) system, will improve the performance of the system. Both SO sub(2) removal and limestone utilization can be greatly increased by the buffering effect of adipic acid. Successful testing in laboratory, bench, pilot, prototype, and full scale systems has demonstrated the benefits of this technology for new and retrofit applications. Although adipic acid does degrade in the scrubber, no significant operating problems or environmental impacts have been identified. Economic estimates have shown the adipic acid enhanced limestone FGD system to be economically attractive when compared to conventional FGD systems. In addition, further research is underway to decrease the cost of using additives in FGD systems. JF - J. AIR POLLUT. CONTR. ASSOC.

I. Slow Cortical Potentials. AN - 15340782; 164313 AB - The effects of body Pb burden on slow cortical potentials were studied in 63 children aged 13-75 months. Slow wave (SW) voltage during sensory conditioning varied as a linear function of blood lead (PbB) level. The slope of this function, moreover, changed systematically with age. For children under 5 years of age, SW voltage tended to be positive at low PbBs and to be negative above 30 mu g/dl. For children over 5 years of age, SW voltage tended to be negative at low PbBs and to be less negative (or positive) above 30 mu g/dl.

AN - 15339932; 167501 AB - Diethyl was determined in water and sediment by high performance liquid chromatography (HPLC) and in water by gas-liquid chromatography with electron capture detection (GLC-EDC). Water samples were extracted with hexane, using a high-speed homogenizer-ultrasonic apparatus and a test tube mixer. Sediments were Soxhlet-extracted using acetonitrile. For HPLC, diethyl phtalate was determined in normal phase mode using a Zorbax-CN column, a 2% isopropanol-hexane solvent system, and a UV variable wavelength detector. For GLC-ECD, a 3% SE-30 Gas-Chrom Q column with a super(63)Ni electron capture detection system was used. Recoveries from fortified samples ranged from 93.9 to 98.0% for water at 0.01-0.50 ppm, and from 90.0 to 93.6% for sediment at 0.2-2.0 ppm.

Fetal and maternal toxicity was observed in both species. In the mouse, maternal toxicity was observed in both species. In the mouse, maternal toxicity was evident at the lowest dose, while teratogenic response was confined to cleft palate at 400 and 600 mg/kg/day. The effective maternal toxic dose in the rat was 40 mg/kg/day. In this species, incidence of irregular palatine rugae was significantly dose-related. The results suggest an "apparent no effect level" for this anomaly below 30 mg/kg/day. JF - Drug and Chemical Toxicology AU - Rogers, E H AU - Chernoff, N AU - Kavlock, R J AD - Exp. Biol.

II. EEG Spectra. AN - 15339740; 164338 AB - This sutdy explored the effect of age and PbB upon EEG power spectraand various measures of hemispheric laterality in children, ages 13-75 months. The delta - and theta -band amplitude decreased with age. When only bilaterally synchronized EEG between P3 and P4 was considered the amplitude of P3 was estimated as greater than P4 in all frequency bands and for all ages. Previous reports have not shown lateral EEG dominance in children below 75 months. When lateral dominance measures consider only the ralationship between synchronized EEG at P3 and P4, bilateral communality in the delta band increased with age. Increased PbB generally produced an increase in the relative amplitude of synchronized EEG between P3 and P4 in all frequency bands. This was true for PbB levels well below 15 mu g/dl, among the lowest level PbB effects previously reported. No clinical or behavioral effects of PbB values have been reported below 15 mu g/dl.

AN - 15337443; 165697 AB - During the summer of 1979, coefficients for light extinction in the atmosphere were calculated from measurements made wtih a telephotometer placed 251 m from a black target in Research Triangle Park, North Carolina. The results are well crrelated (r = 0.92-0.96) with integrating nepnelometer measurements of scattering coeffiecients and are highly correlated ( r= 0.99) with daily arithmetic averages of sums of scattering and absorption coefficients. The average sume of scattering and absorption coefficients accounts for about 90% of the average telephotometrically measured extinction coefficient. Scattering by particles and scattering by air contribute 75 and 7% of the measured extinction coefficient; absorption by particles and absorption by nitrogen dioxide contribute 7 and 2% respectively. From measurements of the aerosol mass and elemental composition, it is inferred that sulfate and its cations account for at least 54% of the mass of particles smaller than 2.5 mu m in dia.

AN - 15335703; 154333 AB - Theories of light extinction and contrast reduction by atmospheric aerosol are reviewed. Errors inherent to telephotometry are analyzed. Significant errors may result from unknown target luminance, stray light within the telephotometer, and uneven illumination due to clouds. Measurements by a telephotometer of the extinction coefficient of the relatively turbid atmosphere of the eastern U.S.A. are described. Because of current levels of extinction, it is feasible to apply a dual target technique developed by Ruehle, which corrects for the targets' imperfect blackness and stray light imperfections in the telephotometer optics. The results compare favorably (r = 0.97, slope = 1.08) to independent measures of scattering and absorption coefficients when the most obvious cases of uneven illumination due to clouds are excluded. The agreement of these two independent measurement methods for extinction coefficient lends credence to them both. However, the difficulty of automating cloud detection for the telephotometer remains a formidable practical problem. JF - Atmospheric Environment AU - Ellestad, T G AU - Speer, R E AD - Environ. Sci.

AN - 15332091; 154246 AB - Many Class I areas have unique vistas which require an observer to look over complex terrain containing basins, valleys and canyons. These topographic features tend to form pollution "basins" and "corridors" that trap and funnel air pollutants under certain meteorological conditions. For example, on numerous days, layers of haze in the San Juan River Basin obscure various vista elements including the Chuska Mountains as viewed from Mesa Verde National Park, CO. Measurements by an integrating nephelometer and a conventional teleradiometer at one location in Mesa Verde do not quantify the inhomogeneities. In this paper, data from these instruments are compared to data derived from scanning teleradiometer measurements of photographic slide images. The slides, surrogates of the real three-dimensional scene, were projected and scanned to determine relative sky and vista radiance at 40 points within a vertical slice of the vista. Comparison of the corresponding visual range data sets for each instrument for September and December 1979 demonstrates the utility of the scanning teleradiometer.

AN - 15327124; 157127 AB - Benzene exposures may affect human health in three ways: (1) increasing the incidence and severity of acute illness, (2) increasing the incidence and severity of chronic illness, and (3) increasing mortality rates. These adverse health effects result in tangible and intangible losses. Examples of tangible losses are time away from work, lower productivity during working hours, and use of medical resources. Intangible costs are the anxiety, pain and fear in individuals and their family and friends. These costs are seldom considered in an economic evaluation of adverse health effects. Information about the adverse health effects associated with benzene exposure is very limited as is evident from the section characterizing risk.

AN - 15323635; 141245 AB - Although RCRA is the principal U.S. law governing hazardous wastes. The Toxic Substances Control Act (TSCA) also contains limited authority to regulate the export of chemicals and chemical wastes which are regulated domestically under TSCA if EPA finds the export will present an unreasonable risk of injury to the health or the environment within the United States. It is under TSCA that wastes contaminated with polychlorinated biphenyls (PCB's) or TCDD (dioxin) are controlled for export. Under present regulations, PCB's may not be exported for disposal unless the U.S. and the other country have entered into a Memorandum of Understanding which establishes mutually agreed upon criteria for their storage, transportation and disposal. At the present time there are no such Memoranda between the U.S. and any other nation, and exports and imports of PCB wastes are banned. For wastes containing TCDD, EPA requires a 60-day advance notice of shipment, and exports are dealt with on a case-by-case basis. JF - EPA Journal AU - Greider, W AD - EPA's Off. Int.

AN - 15319458; 137516 AB - Strains of E. coli recently isolated from human feces were examined for the frequency with which they accept an R factor (R1) from a derepressed fi super(+) strain of E. coli) K-12 and transfer it to fecal and laboratory strains. The majority of fecal E. coli isolates accepted the R factor at lower frequencies than K-12 F super(-). The frequencies with which certain fecal recipients received the R-plasmid were increased when its R super(+) transconjugant was either cured of the R1-plasmid and remated with the fi )strain or backcrossed into the parental strain. The former suggests the loss of an imcompatibility plasmid, and the latter suggests the modification of the R1-plasmid deoxyribonucleic acid (DNA). Passage of the R1-plasmid to strains of salmonellae reached mating frequencies of 10 super(-1) per donor cell when the recipient was a Salmonella typhi previously cured of its resident R-plasmid. However, two recently isolated strains of Salmonella accepted the R1-plasmid from E. coli K-12 R super(+) or the R super(+) E. coli) transconjugants at frequencies of 5x10 super(-7) or less.

III. Alterations of Behavioral Ontogeny. AN - 15316903; 125220 AB - In the hamster, prenatal exposure to endrin at 1.5 mg/kg/day on days 5-14 of gestation produced a persistent elevation in the locomotor activity. Offspring of treated hamsters ambulated 75% more than controls in the open field at 15 days and 45% more at 20 days of age. Long term observations of locomotor activity in the figure-8 mazes indicated that a significant elevation of this behavior was still present at 125 days of age. Non-locomotor behaviors of the offspring (including sexual, rearing and running wheel behaviors) were unaffected. In the second experiment, rats exposed perinatally to endrin at 0.15 or 0.30 mg/kg/day were 30% more active than controls prior to weaning, but not as adults. The similarity of the behavioral changes noted in the young of both species is suggestive of simular alterations of central nervous system function even though endrin produces gross morphological defects only in the hamster.

Organic solvents were more efficient than physiological fluids in removing mutagens from diesel particles, with dichloromethane extracts having the greatest mutagenic activity of the solvents examined. Serum and lung cytosol were more effective than acellular lung lavage fluid in releasing mutagenic activity from diesel particles. The mutagenic activity of diesel particle organics preextracted with dichloromethane is greatly reduced upon the addition of serum and lung cytosol to organics.

AN - 15294028; 122752 AB - Flour and biscuit samples from a school lunch program were analyzed for ethylene dibromide (EDB). Flour samples were extracted with hexane at room temperature with maximum extraction of EDB in 4 days. Biscuits were extracted by steam distillation with hexane; optimum recoveries were obtained by a triple extraction of the sample. Recoveries of EDB from flour and biscuits ranged from 85 to 103% as determined by gas-liquid chromatography on a 15% OV-17 column and a super(63)Ni electron capture detector. Random samples were confirmed by gas chromatography-mass spectrometry. From <8 ppb to 4 ppm EDB were determined in flour and <0.5 ppb to 260 ppb in biscuits. Possible sources for the higher values are discussed. JF - Journal of the Association of Official Analytical Chemists AU - Rains, D M AD - U.S. EPA, Chem. & Biol. Invest.

AN - 15293838; 122634 AB - Vitamin C-deficient and normal guinea pigs were exposed to various concentrations of NO sub(2) or air, and lavage fluid was obtained and analyzed for protein and lipid content. Exposure of normal animals to 752, 1880, 5640, or 9400 mu g NO sub(2)/m super(3) (0.4, 1.0, 3.0, or 5.0 ppm) for 72 hr did not alter the protein or lipid content of lung lavage fluid. However, exposure of vitamin C-deficient animals to the same concentrations of NO sub(2) caused marked increases in lavage proteins and lipids at all but the 752 mu g/m super(3) (0.4 ppm) level. At 9400 mu g NO sub(2)/m super(3) (5.0 ppm), 50% of the exposed vitamin C-deficient animals died, and pathologic study of the lungs showed proteinaceous edema fluid in the alveoli.

AN - 15293729; 123057 AB - Venturi scrubbers are highly efficient in removing submicron dust particles from gas streams. Basically, the gas stream accelerates in the converging section of the venturi to maximum velocity in the throat, where it is sprayed by a scrubbing liquor. The faster velocity of the gas stream atomizes the liquor, and promotes collisions between the particles and the droplets. Agglomeration in the diverging section produces droplets, with entrapped particles, of a size easily removed by mechanical means.

Palladium (II and IV) and gold (III) were the strongest inhibitors of RNase activity. Other strong inhibitors, in decreasing order of effect, were: sodium dedecyl sulfate, silver (I), EDTA, mercury (II), copper (II), thiram (fungicide), platinum (IV), malathion (pesticide), lead (II), and beryllium (II). Intermediate effects were found with other inorganic cations, many anions, and some other chemicals. A number of compounds of different chemical types caused no measurable effect. None of the chemicals tested caused a measurable activation of this enzyme. JF - Environmental Research AU - Christensen, G M AU - Olson, D L AD - US EPA, Environ. Res.

AN - 15288374; 114858 AB - Duckweed (L. perpusilla ), inhabiting a heavy coal ash, secondary retaining basin from a coal-fired power plant, was the most abundant macrophyte sampled during the summer-fall period of 1979. Lemna in the basin accumulated the most abundant heavy and soft metals (Cd, Cu, Fe, Mn, Zn, Cr, Pb, Ni) affiliated with heavy ash to a greater extent than found in water or coal ash sediment. After a14-day holding period under laboratory conditions of low metal influence, some duckweed metal concentrations declined to levels similar to those found in the ash basin sediments, while other tissue concentrations remained higher. During the 10-day laboratory exposure bioassay after the depuration period, high duckweed mortality was evident within 2 to 10 days at concentrations of 10x and higher. The capacity of duckweed to accumulate potentially toxic heavy metals in coal-ash-retaining systems may have an important role upon the displacement of these elements on a seasonal basis. Aquatic elemental releases of duckweed may be minimal during the growing season due to the bioconcentration capability but can be maximal in the fall during the process of natural mortality and the resulting depuration process into the receiving drainage system.

As a consequence of these studies, nationwide trends in concentrations of the benzene soluble fraction (BSO) and BaP were determined for the 1967-70 period from ambient suspended particulate samples collected by the National Air Surveillance Network (NASN). super(3) The 1967-70 trends for BaP were extended through 1972 at 33 urban sites. Recently, BaP data for 1973-77 have become available at most of the urban sites form the earlier study, at some additional urban sites, and at three rural or background sites.

AN - 15280731; 116750 AB - In 1979 the Environmental Protection Agency (EPA), the Department of Commerce (DOC), the Department of Housing and Urban Development (HUD), and the Department of Transportation (DOT) jointly awarded demonstration grants to eight urban areas to develop and test ways to coordinate economic development and air quality improvement. In the approximately two years since the first grant award, a great deal has been learned about how the needs of communities and industries might best be addressed in working toward local economic and air quality goals. The economic development and air quality problems facing the areas receiving AQTAD grants have been more clearly defined. Improved working relationships have developed among state and local agencies. Changes in the direction and emphasis of some of the activities of the grantees have also occurred. This paper presents interim results of the grants program, focusing on activities that have progressed far enough so that some evaluation of their potential success is possible. Where an urban area has made mid-course changes in grant acticities, a preliminary assessment is made of the reasons for the change. JF - J. AIR POLLUT. CONTR. ASSOC.

The Agency provides expertise to the US Department of State and other Federal agencies for negotiations on a number of salt-water issues related to ocean dumping, vessel pollution, the law of the sea, and Antarctic resources. The Agency's largest involvement is in the area of ocean dumping. As lead agency in the Federal Government for implementing the 1972 London Dumping Convention, EPA chairs United States delegations to negotiations held pursuant to the Convention, and provides most of the scientific and policy support for such deliberations.

The method does not require the use of a computer and eliminates the usual trial and error calculations. An infinite mixing height is assumed. It involves a linear or quadratic solution of the gaussian plume diffusion as a function of the effective stack height and a linear approximation of the Briggs plume rise equation. The linear approximation of the former gives results that are within 5% of the gaussian plume results for stability criteria A, B, and C. For stability criteria D, the difference can be as great as 80%. If a quadratic estimation is used, the differences are less than 3% for stability criteria A, B, and C, and are within 18% for stability criteria D. A linear approximation is used for the Briggs plume rise equation. JF - J. AIR POLLUT. CONTR. ASSOC. AU - Baasel, W D AD - Indust. Environ. Res.

The physiological stress indices, scope for growth, oxygen to nitrogen ratio and growth efficiency were calculated. There was a significant decline in the performance and physiological condition of mussels from south to north along Narragansett Bay, and this was associated with increasing pollution.

The ambient gases considered in the chemistry were SO sub(2), NO, NO sub(2), HNO sub(3), O sub(3) and CO sub(2). Raindrops initially at a pH of 5.5 absorbed these gases, and as they fell through a polluted zone, produced SO sub(4) super(2)-a)nd NO sub(3)u- by the oxidation of dissolved SO sub(2) by O sub(3) and the dissociation of HNO sub(3), which reduced the pH. For the chemical mechanism and the below-cloud washout rain events considered, it was observed that: absorption of gaseous HNO sub(3) controlled the acidification in the initial stages of a rain event, and inhibited the production of So sub(4) super(2)- )NO and NO sub(2) played no direct role in the acidification or formation of NO sub(3)u- or SO sub(4) super(2)- )pre-acidified raindrops (pH of 4) were further acidified only by absorbing HNO sub(3).

Linear correlation coefficients of 0.99,0.96, and 0.96 were observed for the three individual sets of measurements, and a linear correlation coefficient of 0.93 was observed for all measurements. Light attenuation-mass measurements showed similar results when the plant was operating at full and half loads. Particle size measurements were made on four different occasions during the study with similar results. The work indicates that an empirically calibrated light transmissometer has the potential for monitoring the mass concentration of particulate emisiions from coal-fired power plants, although the stability of such correlations and the calibration frequencies necessary to maintain specific accuracies need to be better defined.

Risk assessment for the use of materials chosen for RPAR include estimates of worker exposure during various agricultural operations. Observations during earlier field studies in the Columbia Basin Irrigation Project, led us to believe that there was considerable use of captan as a fungicide for seed potatoes. During the spring of 1979 we undertook a study of the potential for exposure to captan of workers involved with various aspects of potato planting.

Emission rates were calculated for SO sub(2), total sulfate, and particulate matter expressed as g emitted/gal of oil fired. Sulfate emissions amounted to approximately equals 13.4% of the SO sub(x) from the sources. The sulfate emission factor was found to be related to the accumulation of V-containing ash in the boilers resulting in the catalytic oxidation of SO sub(2). Nearly 35,000 boilers of these types are operational in New York City, especially in the winter, to provide heat and hot water. Their elevated sulfate emission rates could play a dominant role in the occurrence of elevated sulfate levels near the metropolitan area during winter episodes. JF - J. AIR POLLUT. CONTR. ASSOC.

Persistence of residues from both formulations spilled as concentrates and as simulated drum rinses were followed for up to 45 months. Spillage of encapsulated formulation resulted in the formulation of a solid cake-like deposit on the soil surface, which could be a particularly attractive hazard to small children. At 45 months, soil residues had decreased by 64% for emulsifiable concentrate spills, and 68% for the soil beneath the microencapsulated cake. Residue in the cake itself only decreased by 31%. Soil residue levels from simulated drum rinses were essentially innocuous by 45 months for the emulsifiable concentrate and by one year for the microencapsulated material.

The method provides estimates of the expectation of premature death and the resultant life shortening. Applications to occupational exposure situations are used to demonstrate the technique. Doses ranging from 0.2 to 5.0 rem/yr and over age spans from 10 yr to working lifetimes are investigated. A technique for comparing radiation related mortality with nonradiation related risk of death from on-the-job accidents is introduced. Results show that workers receiving whole body doses equal 5 rem/yr for sustained periods of time incur significant risk of premature death from radiation induced cancer. The risk is estimated, in some cases, to be as high as, or higher than, the average risk of accidental death in high risk industries, depending upon factors such as length of exposure, age at time of exposure, and the radiation risk model used.

The extraction of the compounds from urine is often incomplete and inconsistent. Several different approaches to the problem are currently being investigated In this work, the ion pair is extracted into dichloromethane which contains the alkylating agent, pentafluorobenzyl bromide. Since the non-polar solvent possesses poor solvating ability, it renders the alkyl phosphate highly reactive toward nucleophilic displacement. The resulting pentafluorobenzyl (PFB) ester derivative is thermally stable and highly responsive under conditions of gas chromatographic analysis using a flame photometric detector or nitrogen-phosphorus detector.

However, this film was found to liberate high concentrations of contaminants such as fluorocarbons, solvents, antioxidants, and manufacturing residues. These contaminants could interfere with both hydrocarbon analyses and smog-chamber reactivity studies. Heat treatment of FEP plastic film at 190 degree C for 24 h minimized film outgassing but did not eliminate it. Less outgassing occurred with 2-mil film than with 5-mil film. However, bags prepared from 2-mil film were more fragile than those prepared from 5-mil film. JF - ENVIRON. SCI. & TECH.

The U.S. EPA's RAM (Urban) model was chosen to estimate 24-hour average sulfur dioxide concentrations in the Cleveland, Ohio area. Point and area source emissions, along with a background concentration were included in the modeling effort. Projections from the model made at the ambient air stations were compared to measured sulfur dioxide concentrations. A total of 3020 comparisons were performed at 33 monitoring sites. An analysis of the results illustrates that, on a daily basis, the predictions of the model did not reflect actual air quality. The correlation coefficients of the 24-hour comparisons at the monitoring sites varied from a low of -0.121 to a high of 0.541. When the highest and second highest modeled concentrations were evaluated with respect to the highest and second highest measured concentrations, over a period of a year, a more favorable comparison was observed.

The two chemical treatments tested were reduction and hydrolysis. Both reactions should result in the elimination of the possibility of cyclic reduction-oxidation with resultant generation of super-oxide radicals, which has been proposed as the primary event responsible for the pulmonary fibrosis caused by paraquat. This pulmonary fibrosis can occur with oral or intra-venous administration or local instillation of paraquat.

Elemental and microscopical analysis of size segregated, ambient particulate and suspended soil samples from the rural southwest indicate that the particles are earth crust material. The composition of the soil related materials changes with changing particle size. Smaller particles tend to vary more in their elemental makeup than corresponding large particles. Numerous thin mineral plates with diameters of several micrometers are aerodynamically sized in the smallest sample size range (<0.5 mu m). Since silicon accounts for one-quarter to one-half the total mass in the fine particle size range, it may be a significant causal factor in regional visibility degradation.

The available evidence on the contribution of natural organics in photochemical pollution is conflicting. Emission measurements suggest that natural organics are emitted in amounts comparable to or even exceeding anthropogenic organics. The contrasting data are aerometric, showing natural sources to be minor in the organic loadings of urban and rural atmospheres. In a position based on the aerometric data in combination with reactivity data, natural organics are judged to contribute negligibly to urban ozone; their contribution to rural O sub(3) is less certain, probably not major.

Four orthogonal factors representing O sub(3) formation potentials were derived using the statistical package SPSS; these factors accounted for over two-thirds of the variations in 1978 summer O sub(3) levels at 21 urban-oriented stations. The analysis confirmed that O sub(3) variations are similar among stations within defined geographical areas; this confirmation supports the widely held theory that ambient O sub(3) formations are regionwide. The analysis suggested that trends analysis for determining general progress in improving O sub(3) air quality should be based on aggregate statistics from clusters of monitors rather than from a single monitoring station within areas associated with the derived factors.

The greatest inhibition was caused by mercuric ion and certain heavy metal cations; almost as inhibiting were pentachlorophenol, dicofol, 2,4,5-trichlorophenol, and DDT. Less inhibition was found with other inorganic salts, organo-metals, other organic chemicals, and some pesticides. Apart from dichromate ion, the anions studied had a low to negligible effect on lipase.

The thickness of the diatomaceous earth precoat had more influence than did particle size, and filter efficiency increased as the filter runs progressed. Body feed addition is necessary when such filters are used for drinking water production.

Only partial success has been achieved in determining urban storm flow-generated pollution using the conventional dissolved oxygen parameter. Urban run-off has been identified as a major source of toxic substances, including heavy metals, but little is known about their long-term effects. A simple continuous receiving water quality model has been developed for planning and monitoring waste-water treatment alternatives and a general method is described for evaluating the impact of combined sewer overflows.

Twenty-one impoundment sites cited by the House Subcommittee report have high contamination potential for the following reasons: their proximity to production aquifers, characteristics of the waste water, ineffective liners and barriers, from analysis of well isolation, from monitoring of ground-water quality. The 21 sites are then described in detail and although sites reveal slight to moderate water quality degradation, none of the wells monitored was currently used for drinking purposes.

A modified Grob stripping device, consisting of a stainless steel sparger in a 1 gallon sample container, computerized gas chromatography-mass spectrometry and automatic quantitation procedures were used to provide analytical results from repetitive direct injections and purges of standard compounds from water at the 10-100 mg per litre level for statistical evaluation. The recovery efficiency of five of the seven compounds purged from water averaged 75 plus or minus 22 per cent standard deviation. The incorporation of internal standards is necessary for both qualitative and quantitative analysis.

Improvements in the methods of separation and enrichment of the contaminant fraction, initially involving the use of activated carbon as adsorbent, are followed by an account of the replacement of conventional schemes for classifying organic compounds by the various chromatographic techniques applicable to both volatile and non-volatile organics. In place of the boiling point and functional group reactions, the use of retention times and detector responses has given quantitative data on smaller and smaller sample fractions. Several 'landmarks' in the detection and identification of specific pollutants in raw and treated water samples in North America are cited.

To combine sensitivity with selectivity the combination of mass spectrometric detection with gas chromatographic separation has been adopted by numerous Environmental Protection Agency laboratories, based on the Finnigan electron impact quadruple mass spectrometer. The manner in which computerized spectral matching and identification procedures have been applied, with reference to a central data file of over 40,000 spectra, is outlined. To speed up the matching process a preliminary search among 1000 reference spectra for compounds previously identified as water pollutants has now been instituted.

These include the use of a disinfectant that does not generate trihalomethanes, such as ozone; treatment to lower the precursor concentration prior to chlorination, by effective coagulation, settling and filtration, and removal of THM after formation e.g. by activated carbon treatment. Some modifications of existing treatment facilities for THM reduction are suggested and it is stressed that these must be carefully controlled so that the microbiological quality of the drinking water is not adversely affected.

In all 72 different volatile compounds were detected, although only 13 were common to all five cities, and thus reflecting differences in the raw water sources. Quantitative analyses were performed on several target compounds inclusive of chloroform and its bromine derivatives. Apart from the THM, only nitrochloromethane was present in amounts greater than 1 ppb, and only for two of the cities. Several other chlorinated organics were present in trace quantities and could be formed as a result of the chlorination process from hydrocarbons and other organic molecules present in the raw water supply.

Chlorine dioxide has a similar efficiency to that of hypochlorous acid, but its efficiency increases significantly as pH increases in the range at which disinfection is usually applied. Chloramines are the least efficient form of free chlorine. Ozone is considered to be more efficient as a biocide than any of the chlorine forms but is also the least stable , though pH has little effect on its efficiency. It was found that laboratory studies did not always correlate well with field observations.

An experimental community approach was used which incorporated many natural variables while eliminating potential interference by system-induced variables such as thermal/chemical /nutrient additions and mechanical effects found, for example, at a discharge site. Significant chlorination effects were observed on the abundance of eight dominant species and there was a marked decline in total numbers of individuals collected. Only four of the twelve experiments revealed significant differences in short-term community structures and these were related to changes in species dominance and increased in toxicity due to extreme cold weather. The experiments were carried out in South Carolina.

The separated and concentrated cyanide was determined colorimetrically. The method was used to determine hydrogen cyanide in waters and waste waters. The colorimetric reaction between cyanide and pyridine was considered specific, with ammonia, sulphide and phenol resulting in only minor decrease in colour development. Thiocyanate severely affected the determination of cyanide as did silver and nickel. Sulphide removal was also recommended. Vapour-phase equilibration was not regarded as useful as the diffusion procedure for determining low concentrations of hydrogen cyanide.

Over the range 7-36C, the total number of fish sampled from the intermittently chlorinated thermal effluent was lower than control values when the total residual chlorine was over 15 mg per litre. In the summer at temperatures of 27-30C, the fish avoided a total residual chlorine concentration ranging from 0.19 to 0.28 mg per litre; when temperatures were falling from 26 to 7C, the fish avoided 0.23 to 0.42 mg per litre of total residual chlorine. The fish most frequently sampled, the spotfin shiner (Notropis spilopterus) and the whitetail shiner (Notropis galacturus), avoided areas of the discharge when total residual chlorine was 0.18 mg per litre in the temperature range 24-29C, at 30-40C however, the whitetail avoided 0.04 mg per litre, while spotfin shiners did not decline until levels were above 0.12 mg per litre. It was considered that most fish generally avoid chlorine residuals 50 per cent or less of the median lethal concentrations.

It is estimated that more than 40 million people may be exposed to asbestos fibres in their drinking water as a result of the corrosion of asbestos cement products. It is recommended that asbestos cement materials should not be used in the construction of materials destined for the supply and distribution of drinking water, where those materials are liable to attack by corrosive water. The available data are not considered to be adequate for the construction of a drinking-water standard, but it is proposed that investigations should be undertaken, in areas where asbestos-cement pipes are currently under corrosive attack, into treatment and coating techniques.

The diseases were all of the type which affect the alimentary tract and were shown to be associated with deficiencies in water treatment practices and plant operation and with inadequate public health surveillance. The 'multiple barrier' concept, that relies on placing a number of protective systems between the consumer and actual and potential sources of contamination, appeared to have broken down. Statistics indicate that such outbreaks in U.S.A. increased by 50 per cent in the period 1976-1979 over the period 1971-1975. There has been a steady increase in five-year averages since 1951.

In contrast to the conventional analytical approach, where the identity of the target compound is known, the requirements of environmental monitoring programmes necessitate a 'broad-spectrum' approach capable of revealing the presence of contaminants not previously suspected of being present. The type of detection system required becomes much more sophisticated, and only mass spectrometry is so far capable of producing a satisfactory response. The twin problems of adapting this detection system for non-volatile compounds and of efficient data reduction and evaluation are discussed in the light of recent developments in the Environmental Protection Agency laboratories.

A detailed description of the fractionation scheme is given together with the methods of separation and identification using glass capillary column chromatography and coupled mass spectrometry. Eighty specific volatile organic compounds were identified and several unknown acids present in relatively high concentrations in raw sewage were presumed to be detergent metabolites. Only a few neutral compounds were identified, the majority consisting of straight or branched chain fatty acids, hydroxy acids, miscellaneous acids and alcohols. The effects of activated sludge treatment and physical-chemical treatment of the raw sewage were compared, as well as the effects of chlorination and ozonolysis. Physical-chemical treatment (inclusive of carbon adsorption) had a more pronounced effect in reducing specific volatile components than activated sludge treatment, but more quantitative information is described. Volatile, methylene chloride-extractable compounds constituted less than 25 per cent of the total organic fraction in raw sewage.

The issues addressed during this Workshop together with the conclusions and recommendations emerging from it, are reviewed in this paper . Aspects discussed include the chemistry, toxicology, and microbiology of wastewater reuse, the engineering implications, and the various options for reuse involving groundwater recharge, non-potable supply, and the desirability of formulating a unique set of drinking water standards, irrespective of the source of the supply. In the implementation of schemes for reuse, it is considered that non-potable reuse should be the initial goal, with the more exacting question of potable reuse to be considered at a later date.

It is defined as the minimum concentration of a substance that can be identified, measured and reported with 99 per cent confidence that the analyte concentration is greater than zero. Chemical and statistical analytical procedures are described to provide a method detection limit that may be used to judge the significance of a single measurement of a future sample. The effects of interference in specific matrices and an iterative procedure for overcoming erroneous estimates of method detection limit, are discussed. It is recommended that the full regression treatment should be used, when economically feasible. A bibliography of 31 references is appended.

One of the mills was solely dependent on biological treatment with a plastics media biological filter in series with an aerated lagoon, and the other employed a combination of lime coagulation followed by extended biological stabilization (3-6 month retention) in a non-aerated lagoon. The contaminants and their method of extraction and identification are described at length; they were grouped into four main classes, comprising volatile acids, phenolic compounds, long-chain fatty acids and resin acids. Phenols appeared to be the most susceptible to treatment, while the numbers of fatty acids in the waste water from the mill employing the aerated lagoon as a second-stage process actually increased, probably due to the action of the lagoon biota. Details of all the constituents identified and their concentrations at successive points in the treatment chain are tabulated.

The first involves the analysis of drinking water and the raw water source (Ohio river) at Evansville, Ind. , using carbon adsorption techniques for separation of the organics; the second concerned a survey of drinking water samples from four U.S. cities in EPA Region VII, using resin adsorption methods, and the third examined the formation of trihalomethane compounds from water containing added bromide, chloride or iodide ions during the chlorination process. The Evansville investigation revealed the presence of bis(chloropropyl)ether in the treated water supply at 0.3 ug per litre, the source of which was treated to an industrial discharge containing 2760 ug per litre of this compound at a point on the Ohio river 150 miles upstream from the Evansville raw water intake. The drinking water sampled from the four cities in Missouri and Kansas contained detectable amounts (about 0.1 ppb) of several herbicides, presumably due to agricultural runoff into tributary streams, as well as THM formed during the chlorination stage .

Problems arising due to the presence of residual chlorine and a gradual rise in haloform concentration during storage of the sample were overcome by treating the sample with potassium ferrocyanide at alkaline pH. The treated water was then purged with helium after heating to 95C and the volatiles separated on a column of 60/80 mesh Tenax GC packing, for subsequent analysis by gas chromatography coupled with mass spectrometry. The design of the purging apparatus and the provision of specially purified water free of volatile organics, for use as a blank, are also described.

The retention volumes were shown to be positively correlated with the octanol/water partition coefficients when plotted using double logarithmic co-ordinates. In view of the previously established correlation between bioaccumulation factors and octanol/water partition coefficients, it is suggested that the reversed-phase HPLC system may be employed as a screening tool for those compounds in water and effluents most liable to be subject to bioaccumulation in the aquatic environment.

No. 1035) , to govern the effectiveness of zinc compounds as inhibitors of the corrosion of aggressive waters towards asbestos cement (AC) pipes. The Aggressiveness Index for describing the tendency of a water to damage the structure of AC pipes is criticized. A model is developed for the complexation and solubility equilibria of zinc and is extended to show how similar considerations of the aqueous equilibria of other cations and anions may be used to provide more effective prediction of the aggressiveness of a water towards AC pipe in distribution systems. The model has been applied to laboratory pipe-loop coupon tests and field data. A bibliography of 91 references is appended.

The thirteen sites comprised three treatment works in the New Orleans area and ten cities in different parts of U.S.A. selected for the National Organics Reconnaissance Survey. Details of the procedures and typical chromatograms obtained from the gas chromatographic mass spectrometric procedures are included. A total of over 100 compounds were detected, of which 82 contained in XAD-2 resin extracts and 50 in carbon-chloroform extracts prepared from the original samples. Methods for identification of several compounds, chiefly herbicides or insecticides and their derivatives, are described. No polycyclic aromatic hydrocarbons (PAH) or PCB were detected in any of the samples. The identity of one compound present in two of the New Orleans treatment plants and at Cincinnati was confirmed as trimethylisocyanurate, but the origin of this compound is mysterious.

The synthetic leachate had a chemical oxygen demand of 22,000 mg per l, and was dosed at rates of 100 to 400 mg COD per litre into the inlet stream of a three-stage aeration tank operated with a sludge retention time of 1.5 day. Records of the changes in operating parameters (specific oxygen utilization rate , oxygen uptake, mixed liquor suspended solids and sludge volume index) were performed during the periods of injecting the leachate at a constant rate for both the treatment and control systems. The results confirmed that the aeration requirements and the mixed liquor suspended solids increased in response to increased proportions of leachate in the feed , while at the highest dose rate the settled sludge volume increased and sludge settling characteristics deteriorated to the point where bulking of the sludge occurred and sludge solids overflowed into the outlet from the upflow clarifier. Further consideration of the problem of sludge bulking at high COD loadings is indicated. JF - Land disposal: municipal solid waste (edited by D. W. Shultz).

Other factors such as the seasonal effects of snowmelt and problems caused by the nature of the soil are reviewed in the light of seasonal fluctuations in stream water quality observed at selected monitoring sites. The stage of development of empirical models of the effects of acid precipitation, as well as of more precise process models is briefly considered.

Several types of shipboard incineration systems are compared, with operating temperatures ranging from 820 to 1600C, and their suitability for disposal of waste in different forms and with different physical characteristics is discussed. Existing harbour and terminal facilities in the U.S.A. were reviewed as part of the survey, and those that would accommodate ships similar in length and draught to the conceptual incinerator vessel were identified. The most suitable terminals for such operations were selected on the basis of available cargo handling facilities and management awareness of environmental controls. Recommendations for the further development of such ocean going vessels and support facilities are presented. Some aspects of the disposal system such as the use of single-pass venturi scrubbers with sea water injection, require further evaluation.

Maximum cell densities in the Little Miami river were attained after 1-2 weeks (except in November) and in the Ohio river after 4 weeks in June and July or 1 week in August and September, while in November the cell density continued to increase as the period of exposure increased. District successional patterns in the composition of the periphyton populations were not observed, the changes with increased exposure time resulting principally from seasonal changes in ambient conditions and phytoplankton populations. The periphyton in both rivers were dominated by diatoms, which averaged 68 per cent of the total cell count. Detailed inventories of species observed are included.

Copper was continuously fed to a small calcareous stream at a concentration of about 120 ug per litre, and changes in the composition of periphytic organisms observed over a ten month period (February-December 1970). Very detailed observations are reported concerning the species composition and abundance of various planktonic organisms in the treated reach and in a control reach of the same stream . Two of the dominant algal species were eliminated from the stream , Cocconeis placentula which formerly contributed from 85 to 98 per cent of summer diatoms, being replaced by three species of diatoms, while several othr species were more abundant in the copper-treated section, including one filamentous blue-green alga and two desmids.

Three alternative approaches are distinguished: namely, measurement of the biological properties of the effluent using captive organisms in the laboratory, similar studies with captive organisms in situ, and an assessment of the biological integrity and community structure of the receiving water body. The relevance of each of these approaches is considered in turn, and published reports concerning accepted methods and case studies are reviewed; while the parameters measured in various situations are summarized in tabular form. More systematic data collection and evaluation is required to take the place of the largely qualitative information on species composition and diversity hitherto recorded.

The methods involved the OECD sublation and concentration procedure in conjunction with an ionic exchange resin for removal of ionic surfactants, and the use of the cobalt thiocyanate analytical test method for the soluble CTAS content. A commercially available primary linear alcohol ethoxylate was shown to be a suitable nonionic reference material. The methods were shown to be relevant to the formation of a protocol for analytical estimation of nonionics in treated and untreated wastewaters, which was sensitive to both polyoxyethylene alcohols and alkyl phenol ethoxylates, without being specific to any particular nonionic species .

The material was subjected to leaching tests in a number of tall cylindrical columns of 12 in diameter, with an internal system of collection for the leachate. Layers of pyrites waste were interspersed with other materials, such as lime, sewage sludge and fertilizer, as well as a covering of topsoil. Substantial improvements in leachate quality resulted when a covering soil layer of greater than 2 ft depth was applied, and incorporation of the other materials into the upper layers of the waste column also offered considerable benefits. Growth rates of surface vegetation were also increased. JF - Proceedings 36th Industrial Waste Conference.

Recolonization experiments in estuarine soft-bottom communities in Maryland and Oregon suggest that: Many estuarine softbottom communities do not experience an explosive increase in macrofaunal opportunists or an increase in secondary production after physical disturbance. Species abundant in undisturbed communities may be the dominant early colonizers rather than rare opportunists. Meiofauna may dominate early colonization in some communities.

Emphasis was placed on solubility and susceptibility to oxidation, based on chemical tests and also on the BOD of aqueous emulsions formed from specific compounds. With the aid of laboratory and field test results concerning biological treatability, each cluster was assigned an effluent limitation ceiling (designated ETEL), ranging from 1.0 ug per litre for PCB up to 100-1000 ug per litre for chloroform. Good correlation coefficients were obtained for double logarithmic plots of solubility parameters versus ETEL values. The system represents a practical application of structure activity relationships which can be of significance in assessing the biodegradability of organic chemicals.

AN - 13569615; 457594 AB - Residues of octachlorostyrene (OCS) and related polychlorinated compounds including isomers of heptachloro-, hexachloro-, and pentachlorostyrene; hexachlorobenzene, pentachlorobenzene, isomers of tetrachloro- and trichlorobenzene; and hexachlorobutadiene have been quantitated by multiple-ion-detection gas chromatography-mass spectrometry in Great Lakes fish collected between 1974 and 1980. The results show that the two upper lakes, Superior and Michigan, do not appear to have residues of OCS greater than 5 ng/g, while residues in the lower lakes, Huron, Ontario, and Erie, are as high as 400 ng/g. A selected tributary to Lake Erie has been shown to contain very high levels of all of the chemicals studied which suggests one possible source of chlorostyrenes in the Great Lakes.

AN - 13563975; 456900 AB - Data on growth of post-larval and juvenile silversides (Menidia menidia ) at ambient Narangansett Bay water temperature, at ambient plus 8 degree C and at temperatures between ambient and ambient plus 8 degree C are presented. Results show an increase in growth is obtained by rearing the fish at temperatures characteristic of shallow marshes rather than those of open bay waters. Thus, for use in toxicological bioassays, experimental animals cultured at 26-29 degree C may be obtained whose daily growth rate more closely approaches that of field fish than does that of fish reared at 18-21 degree C.

Calculated results agreed well with data obtained from pipe loop solubility experiments at inorganic carbonate concentration values of 25, 100, and 200 mg per liter as CaCO3. This model increases the predicted minimum molar solubility of lead by factors up to 10,000 over those suggested by 2 previous models which ignored lead carbonate complexes. A general reversal in trend occurs with increasing carbonate concentration, and curve shapes are changed compared with previous models. Results show that there is little advantage to increasing the carbonate level beyond 30-40 mg per liter as CaCO3 in the pH range of 8-9.5. A minimum concentration of carbonate overcomes the higher solubility of lead hydroxide, but an increase in carbonate promotes formation of more soluble lead carbonate complexes. None of the pipe loop tests reduced lead concentration to below the 0.05 mg per liter maximum contaminant level at carbonate concentrations of 0 to 7,950 mg per liter as CaCO3.

The 760 mm diameter filter column contained 1.5 m of No 3 anthracite above 760 mm of No 612 sand on a 460 mm gravel base. CSO treatment at 11 liters per sq m per sec removed suspended solids at an average of 62% across the filter and 66% across the system. BOD removals were 32% and COD removals 40%. Polymer and alum additions improved removals to 38 % for BOD and 50% for COD. Treatment of RDWWW at 5.4 liters per sq m per sec produced suspended solids removals of 67% across the filter and 70% across the system, BOD removals of 33%, and COD removals of 32% across the filter. Addition of polymers improved performance to 39% for BOD and 34% for COD at flow of 8.1 liters per sq m per sec. Use of polymers plus alum did not improve filtration further. Since % removals of suspended solids are dependent on the strength of influent flows, the filtration system should be rated on the basis of total solids captured per unit filter area. This should be at least 15.1 kg per sq m for RDWWW and 22.0 kg per sq m for CSO. Settleable solids were removed to an extent of 95% or greater, but dissolved materials were not removed.

Actions that develop from regulations affect sampling, and conversely, analyses and sampling are used as a basis for setting standards. Procedural problems are illustrated by the example of the dieldrin residue limit for animal feed established by the U.S. EPA. This standard was set by relying on the fish bioaccumulation factor rather than acute and chronic toxicity data, arriving at a value of 0.005 ppb, which is not detectable except by the most refined research techniques. This makes routine sampling and analysis suspect. Suggestions are made for improvements to the National Pollutant Discharge Elimination System reporting system, to make the data received more useful. Testing and analysis problems are illustrated by the cyanide standards hearings held in Illinois, which took 3 years to develop a 0.005 mg per liter standard, a level which requires development of new analytical methods. Two groups within EPA are now working on the ammonia effluent standards, making possible a double set of regulations. Recommended sample preservation procedures are frequently impractical and expensive. However, in the case of phenol sampling, only one general sentence was given as instruction. Further problems involve collection of composite samples, trace organic compounds, rounding of results, and lack of objectives described for the data acquired.

Samples from several locations throughout the U.S. possessed some common characteristics. A multitude of crystal arrays were found beneath a hard, porous surface. Microorganisms were seen at or near the surface of the tubercles, where nutrients and oxygen are continually present. Diatoms and algae were present in pipes from areas which do not use filtration for treatment of surface waters. Actinomycete bacteria were identified in several specimens. By sequential magnification of a porous specimen, organisms were found growing beneath the surface veneer. The presence of these microorganims in the distribution systems does not reflect inadequate treatment, but rather the adaptability of the microbes to their environment. The populations may be decreased by reducing the nutrient and particulate levels and by improving corrosion control. In severe cases, reconditioning or replacing old water mains and eliminating dead ends may be effective.

However, the magnitude of these changes is expected to be somewhat less than has been experienced in the past decade. Desires will be balanced with realistic goals. Economics will become important in the making of decisions. Attention must be given to the management of the various programs. Decentralization of program administration is recommended. Simplications are needed in the various regulations, with incentives introduced and maintained in the management levels of regulatory programs. Changes will be made in the awarding of construction grants and in the ways in which wastewater facilities are to be operated. Concern will continue in the area of toxic pollutants in the environment, and increased testing will be performed on laboratory animals to determine possible toxic effects on humans. Programs will be developed for controlling nonpoint sources of pollutants. (Baker-FRC) JF - Water and Sewage Works Vol 127, No 10, p 38-40, October, 1980.

A total of 77,678 sites were identified, 10,819 of which the were industrial sites, which were given highest priority in subsequent analyses. The industrial waste sites are estimated to cover about 430,000 acres and receive 50 billion gallons per day of influent. Fewer than 30% are lined, and more than 95% have no regular monitoring. About half the sites contain waste which may have potentially hazardous constituents. Thirty percent overlie usable aquifers and are underlain by zones which allow free movement of escaping wastes. About one third of these sites are within one mile of a water supply well which would be in the path of contaminated water flowing from the site. Similar lack of proper siting, design and monitoring is indicated in the information obtained for municipal, agricultural, mining, and oil and gas brine waste liquids sites. The industrial and municipal sites pose the greatest threat to drinking water resources, while the remainder threaten agricultural groundwater resources. The minimal monitoring of the waste sites results in discovery of contamination only after gross, noticeable environmental changes occur.

Multiple-hearth and fluidized bed incinerators are used in the U.S. The environmental impacts of incineration include water pollution due to boiler blowdown and scrubber water discharges as well as ash handling and disposal. Most of the heavy metals found in sludge are concentrated in the ash at levels of > 1%. Poor incineration can lead to the formation of odorous, partially oxidized hydrocarbons (e.g., aldehydes, ketones) and sometimes sulfur oxides. Uncontrolled particulate emissions may vary from 4-110 kg/mg dry sludge input, depending on incinerator type and sludge composition (e.g., percentage volatile solids, moisture). Organic pollutants, including polychlorinated biphenyls, low-molecular weight hydrocarbons, and heavy metals, may be emitted if operating conditions are inadequate. EPA tests of a fluidized-bed incinerator in the New York metropolitan area indicated that, when incinerator temperatures increased from 1 ,200 to 1,750 F, lead emission increased 25-fold (3.1-77.0 mg/g) and cadmium increased almost 10-fold (1.0-8.1 mg/g). These increased emissions are associated with respirable particles of 1,800 F). This would be followed by air-pollution control, so most of the toxic organics would be destroyed.

The two resins recovered about 40 compounds each at 75% efficiency. By combining the two resins, 63 compounds were identified. Liquid-liquid extraction recovered 90 compounds at 65% efficiency. Using either resin with liquid-liquid extraction recovered about 110 compounds with efficiencies varying from 58.6 to 76.8%. When the total acid fractions were derivatized, 132 to 136 compounds were observed. Efficiency of collection varied from 63.8 to 97.1%. These results suggest that the characterization of complex wastes requires simultaneous collection of samples by several methods.

To meet these goals, the NMPS defines a process for issuing extensions with enforceable compliance schedules based on grant funding; lays the foundation for the coordination of grant, permit, and enforcement operating practices; and describes enforcement and grant actions as they relate to State Project Lists. These mechanisms contain the following our elements: (1) development of a municipal noncompliance classification process; (2) provision of enforcement/grant procedures for facilities requiring treatment more stringent than secondary; (3) introduction of a municipal referral priority system; and (4) authorization of formulation of a municipal management system to implement NMPS. Despite large Federal municipal grant expenditures, about 65 percent of all major publicly owned treatment works were in noncompliance with municipal pollution abatement regulations as of July 1, 1977. The municipal management system combines a range of compliance, enforcement, and construction grant actions with a system ranking candidate municipalities for judicial action in an attempt to coordinate national compliance efforts.

It is equally clear that while the catalog of available models is quite large, only a few are in common use. Future model use will emphasize applications. New model development will proceed at a slower pace until an adequate data base is available. Receiving water quality models will receive increased use. The use of mini/micro-computers will increase rapidly, and models will be adapted for use with low cost hardware.

Irrigated agriculture and the construction and operation of multi-purpose and hydro-electric power dams have affected water quality. Industrial development has also produced subtle, long-term water quality changes. In the 1940 's and 1950 's a significant problem was a slow rise in the overall temperature regimen. The first major problem affecting users was the development of slimes associated with the sheath bacterium Sphaerotilus which coated fishermen 's nets and lines. State and federal actions, including the Federal Water Pollution Control Act of 1967 helped solve this problem in the early 1970's. In the 1960's, municipal and industrial waste discharges produced unsafe bacteriological levels; however, this is now controlled, as is a condition known as ' dissolved gas supersaturation ' which resulted in losses of 80-90% of downstream migrating salmon. Elevated, almost lethal, water temperatures are still a pervasive problem caused by: (1) dam construction which increases surface area, slows the river flow and produces temperature stratification; (2) point source heat discharges, such as from nuclear power plants; (3) irrigation withdrawals and return flows; and (4) deforestation. To a lesser degree, the water is affected by spills of oil and other hazardous materials. Recent environmental legislation is working toward minimizing these environmental impacts but continued vigilance by the public is also necessary.

Statistics are given on waterborne disease associated with contaminated groundwater. The effect of rainfall patterns on microbiological quality of groundwater supplies is described. A case of Salmonella pollution in the absence of coliform pollution is attributed to lizards in the wells. Petroleum in groundwater is slow to degrade because dissolved oxygen, organic nitrogen, and phosphorus are limited. A study on viruses indicated that a soil pH of 5 or lower resulted in good absorption of viruses. With respect to bioindicators, antibiotic-resistant E. coli proved more suitable as a tracer in monitoring soil water movement than fluorescent dyes. Several studies were done on movement of microorganisms through the soil after application of domestic or farm wastes. Bacteriological aspects of oil and gas drilling were discussed. Methanotrophic bacteria were found associated with oil and gas well water. Bacteriological consequences of using carbohydrate polymers in drilling fluids were discussed.

Rainfall runoff quality data were gathered from 47 catchments in 25 cities and assembled on a storm event basis to study the characteristics of storm runoff and its effects. Indicator bacteria and pathogens were taken from waste water, urban streams and stormwater in another study conducted in Baltimore, Md. Quality of urban runoff was also studied in Burlington, Canada; Northern Guam; Durban, South Africa; Denver, Colorado; the Delaware River; and Berkeley Hills , California. The development of urban hydrology was reviewed in several areas. The understanding of the impact of pollutants on receiving waters was enlarged through several research projects including ones in Knoxville, Tennessee; Lodi, New Jersey; Los Angeles; Newark, Delaware; Hawaii; San Jose, California, and additional sites. Urban stormwater runoff studies using transient flow models were used to study proper management of runoff events. Control of combined sewer overflows was examined from the viewpoint of source controls, collection system controls, and off-line storage and treatment. Studies also dealt with the treatment and disinfection of stormwater runoff and combined sewer overflows.

Tests were performed in a flowing water system using unfiltered Lake Superior water. Concentrations for endrin were 0.03, 0.07, 0.15, 0.26, and 0.60 micrograms per liter and for methoxychlor, 0.15, 0.42, 1.30, 2.17, and 4.23 micrograms per liter. The isopod Asellus communis was most sensitive to methoxychlor; EC50 (behavior) was 1.78 micrograms per liter at 4 days, and 0.42 at 28 days; LC50 (survival) was 1.75 at 7 days and 0.42 at 28 days. Caddisflies (Hydropsyche sp.) were less sensitive. LC50 was 2.90 micrograms per liter for methoxychlor at 14 days and 1.30 micrograms per liter at 28 days. Stoneflies (Pteronarcys dorsata) and snails (Physa integra) showed no deaths in 28 days in 4.20 micrograms per liter methoxychlor. Endrin toxicities (all in micrograms per liter) were as follows: caddisfly (Brachycentrus americanus) EC50, 0.23 at 4 days, 0.017 at 14 days; LC50, 0.34 at 4 days and greater than 0.34 at 21-28 days; stonefly, EC50, 0.22 at 4 days and 0.05 at 21-28 days, LC50, 0.28 at 7 days, 0.07 at 28 days; bullhead (Ictalurus melas), LC50, 0.45 at 4 days, 0.10 at 28 days. Bioaccumulation factors were: for methoxychlor, stonefly, 348-1130, and snail, 5000-6710; for endrin, stonefly, 610-1033.

The water sample is maintained with no air space under sealed conditions after collection and during pH measurements. Other precautions are having the buffer and samples at the same temperature, storage of buffers in closed containers, and a constant and not too high stirring rate. The pH of a sample with 3.27 mg per liter of calcium carbonate alkalinity was determined by the suggested method and varied by only + or - 0.002 units over 30 min. When the pH measurements were done with the sample open to the atmosphere, pH increased by 0.8 units over 30 min. This method is not necessary for samples already in equilibrium with the atmosphere or with a very high buffer capacity.

Many studies concentrated on chlorine dioxide and its inorganic byproducts, chlorite and chlorate. Chlorite produces methemoglobinemia in humans and laboratory animals. Unlike nitrite, chlorite is hemolytic. Similar changes are produced by chlorate, but the observed changes disappear with continued exposure after 2 months. No significant effects of 5 mg per liter chlorite in drinking water were observed in the population of a small town. However, red cell glutathione and 2,3-diphosphoglyceric acid were not determined. One individual with glucose-6-phosphate dehydrogenase deficiency showed 15% decreases in hemoglobin and hematocrit during the period when chlorite was used for disinfection. Rats exposed to monochloramine in drinking water at concentrations up to 100 mg per liter for 45 days showed no overt adverse effects. However, patients undergoing kidney dialysis with chloramine-treated water suffered acute hemolytic anemia. The organic reaction products of disinfectants include trihalomethanes, known carcinogens. One study investigated the susceptability of mice to tumors produced by painting the skin with tumor promotors and disinfected Ohio River water concentrated by a factor of 102-186 by reverse osmosis, which does not concentrate trihalomethanes, but higher molecular weight compounds. No tumors were produced by nondisinfected water or water treated with chlorine dioxide plus tumor promotor. Tumors were produced by disinfection reaction products plus tumor promotors as follows: chlorine, 4 of 25 animals; chloramine, 5 of 25 animals; and ozone, 7 of 25 animals.

The primary pathways by which radioactivity reaches a dose receptor are: direct external gamma exposure from airborne or groundwater deposited radionuclides; inhalation of radioactive materials; ingestion of radionuclides through contaminated foodstuffs; and ingestion of contaminated water. Congress has provided the Environmental Protection Agency (EPA), Nuclear Regulatory Commission (NRC), and Department of Energy (DOE) with a patchwork of Acts directed at specific processes associated with uranium mining and milling. In many cases, EPA has been ordered to set standards in consultation with NRC and DOE, and the latter two agencies are to implement them. Existing, proposed, or planned regulations will protect the environment from all effluents except groundwater contamination from milling activities. In addition to developing regulations for the uranium fuel cycle, EPA aids NRC Agreement states in their review of impact reports submitted by applicants for milling licenses. NRC solicits EPA review of environmental impact statements that NRC develops for milling projects under its jurisdiction. Future cooperation with the Fish and Wildlife Service may aid EPA efforts to control mining and milling effluents.

Because each public system is different, it is difficult to generalize about the uniform application or removal of ICR systems across the nation. EPA is attempting to gain more flexibility in consideration of the individual circumstances of the grantee and its industrial users. The possibility of an increase in the Gpd flow exemption rate is considered, as it would lessen the administrative burden on certain grantees and would benefit many more small firms that are not able to finance self-treatment facilities. Another possible step would be to exempt grantees demonstrating existing funding mechanisms that provide for future capital expenditures. Exempted grantees would have to show that elimination of ICR would not produce a disproportionate share of current and future treatment system costs being imposed on residential users. Another option is to permit grantees to avoid ICR requirements if industrial capacity financing is not sought from the federal government.

This avoids the problems of a too-narrow or too-wide allowable variation by eliminating 10% of the results from consideration. This proposed change would effectively double the allowable operating mean and the daily excursion point. Both regulators and dischargers would have a clear definition of satisfactory operation and multiple criteria (numerical compliance, expected variability, frequency, and magnitude of violations) for scoring compliance. Either composite or grab samples may be used. (Cassar-FRC) JF - Environmental Management Vol 4, No 3, p 241-245, May, 1980. 1 Fig, 9 Ref.

In addition, the Agreements may be an important vehicle for communicating the direction of EPA and State programs to the public. For the 1980 fiscal year, Agreements have been completed in all six Midwestern States. FY 1981 will see Michigan, Indiana and Ohio with Great Lakes SEA issues, and New York may also develop a Great Lakes SEA highlight in connection with a special regulatory assessment, and broad scale intensive survey of the Niagara River in New York. Both the draft Indiana and Ohio SEA 's focus on special problems in nearshore areas of the Great Lakes, estuaries, harbors and beaches which are seriously degraded due to point and nonpoint pollution. In all the State/EPA Agreements, specific tasks are assigned to the State and Federal partners, milestone schedules are established, and funding and responsible party assignments are settled.

In studies of the biotic effects of sediemnts, two broad classes of sedients can be distinguished, organic and inoranic. In first, second, and third order reaches of streams, energy input into the system derives from stream-side vegetation. Coarse Particulate Organic Matter (CPOM) is broken down and fragmented into Fine Particulate Organic Matter (FPOM) which is subsequently transported downstream. The mid-reaches of the stream continuum (fourth through sixth order streams) is the major region of primary productivity, and FPOM is the dominant variety of import material. Further downstream (seventh to twelveth order) th stream energy economy again shifts and becomes heterotrophic, with more turbidity and an increased importance for plankton. The increased turbidity reduced light penetration, the potential for photosynthesis is reduced, and substrate availability for periphyton is reduced. Inorganic sediments are generally assigned on the basis of size and physical method of transport to suspended load or bed load. Suspended loads typically are silts and clays supplied by the watershed. Bed load is composed of larger particles including sand and gravel which are not typically a part of the water column. Biotic impacts of bed load movement are generally attributable to abrasion, scour, and burial. Suspended load increases turbidity, and may interfere with photosynthesis and rspiration.

Problem existing in Region V include: lack of information entered into the STORET data base; possible excess of fixed monitoring stations; use of intersive surveys for single programs rather than multiple purposes; and insufficient monitoring of toxic substances because of lack of resources. The Basic Water Monitoring Program is directed to the protection of the public health through monitoring of toxic and hazardous sources of pollution, and the more traditional pollutants. The components of the program are: ambient monitoring (including toxic monitoring), effluent monitoring, intensive surveys, biological monitoring, quality assurance and STORET.

The test is cheap and simple, but has the disadvantages of possible changes in the toxic substance, due to volatility, degradation, adsorption, or uptake by the organisms. Fish bioassays frequently use fathead minnows as they can be cultured to reduce the variables that would be present in wild fish; channel catfish and blue gills are possible test fish, as are trout if cold water fish are required. Strict quality controls are necessary if the validity of the test is to be assured. Maintenance of a healthy stock of fish, a well-designed laboratory, inert containers for fish, thorough cleaning of containers between tests, acceptable dilution water and dissolved oxygen levels are factors to be considered. A list of the items that should be in the report of the static bioassay is presented.

The units can be arrayed in pairs or series for multiple tests. The apparatus has been used to determine sediment effects in riverine systems and lakes. A river system test was conducted to determine 96 h toxicity of sediments on Hexagenia limbata, Asellus communis, and Daphnia. The toxicities of the sediments were such that it appeared that reduction of a thermal discharge might result in no improvement in the river habitats. The apparatus has also been used to determine toxicity of harbor sediments and provide indications for the disposal of dredged material. If pollution is not severe , the dredged material may be disposed of in the open lake; severely polluted material requires secure land disposal. Useful information is being obtained from the test but refining is needed to improve its replicability.

The achievable goal is to provide test organisms which are healthy, relatively free of pollutants, of known age, physiologically representative of the species, and a culture environment which does not cause stress. Organisms may be reared in the laboratory, obtained from a hatchery, or collected from the wild. This last is the least satisfactory because of the unknown status of the organisms, but with the exception of Daphnia is the only source for invertebrates. The advantages and disadvantages of rearing fish and obtaining them from a hatchery are discussed. Rearing a continuous supply of fish is considered to be most satisfactory, given the initial costs and additional staff for culture maintenance. Recommended freshwater, estuarine , and marine species and test temperatures are listed, as are the prophylatic procedures conducted when fish are obtained from outside sources, and organic contaminants that have been found in fish diets.

EPA authority for requiring biomonitoring stems from Section 308 of the Clean Water Act, and the states must have similar authority in order to receive NPDES authority. Biomonitoring will be required of major dischargers, especially chemical-based industries, and of minor dischargers if evaluation of the facility, process, and treatment suggest the liklihood of toxic discharges. Major emphasis will be placed on discharges to the Great Lakes and their tributaries. State water quality standards will be used to develop permit limits for toxic substances, but where biomonitoring shows that a substance at levels below the standard is bioaccumulated by organisms or is carcinogenic, teratogenic, or mutagenic, new lower standards will be required. Industries are recommended to begin testing so that they will have information and time to make changes if they are deemed necessary, rather than waiting for enforcement actions.

A previously developed recirculating static model ecosystem was simultaneously used with the flowing water system to test the behavior of pentachloronitrobenzene (PCNB), simazine, and trifluralin. Pesticides were introduced to the static system at ranges of 0.1-100 ppm and at 0.1-100 ppb in the flowing system and the effects were observed on Daphnia magna, Oedogonium cardiacum, Helisoma sp., and Gambusia affinis. The results indicate that both models are valuable tools for determining the fate and behavior of pesticides in the aquatic environment, but cannot be routinely substituted for each other. The static model system simulates a sediment or erosional pesticide source and provides conditions for chemical and biological degradation, while the flowing-water model system simulates an effluent pesticide source and provides continuous chemical exposure to the organisms. Trifluralin which is rapidly degraded was accumulated to a high level in the flowing system, but degraded and so not accumulated in the static system, whereas there was little difference between the systems for the long-lasting pesticides. If the compound is reasonably degradable the flowing system will give the most reliable information, but either system will give good results for the less degradable compounds.

When the National Organics Monitoring Survey showed 10 ppb carbon tetrachloride in drinking water at Huntington, West Virginia, Section 308 inquiries were initiated. Three of the four companies involved cooperated, while the fourth refused self-sampling and analysis. On Feb. 9 Cincinnati tap water contained an exceedingly high level of CCl4, 80 ppb. Additional sample results indicated a 70 ton slug of solvent in the Ohio River. Increased river flow caused EPA computations of the slug 's location to be in error; it had passed the cities several days earlier than expected. Additional spills were reported on Feb. 24 and March 9. Under the emergency provisions of the SDWA and FWPCA, a restraining order was issued to control future discharges. The 70 ton slug and other spills cost government agencies $356,940, and the public undetermined acute and long-term health problems. The EPA has taken measures to limit future discharge of CCl4 into these rivers. The experience of this spill has generated some ideas for preventing future crises: monitoring selected pollutants routinely, formalizing the guidelines for safe levels of various compounds in drinking water, coordinating emergency responses in the hands of one person, mobilizing laboratory facilities and toxicological advice, reviewing NPDES permits, developing a better predictive model for flow in the Ohio and Kanawha Rivers, and implementing a predetermined contingency plan.

In general, point source problems are usually known and addressed with NPDES permits or section 201 municipal construction grants programs, while most of the nonpoint problems are known only in gross terms. A coordinated and integrated approach to point source and nonpoint source related aspects of pollution problems in specific areas is one of the primary features missing from current WQM plans. The lack of coordinated approaches can be remedied by taking all present pollution sources into account when devising geographic priorities for future study and implementation. It is inefficient to attempt to implement structural or nonstructural abatement methods across the countryside regardless of the variable locations and magnitudes of the problems. Five complementary approaches to water quality abatement are: following integrated sub-basin priorities; interagency cooperation; costsharing; regulation; and provision of more direct information and assistance to specific implementing agencies.

New sensing mechanisms and a variety of on-site studies allow a broader and deeper understanding of this phenomenon. On-site treatment system failures may be surface failure and overload flows, groundwater failures or elective failures. Surface failures are usually associated with clogging mat formation, and may be complicated by tight soils or hyudraulic system overload. Groundwater failures are most common on soil of medium to high porosity, and are not usually associated with clogging mat formation. Since the groundwater effluent plume often moves along the surface of the aquifer, its effects are greatly complicated by groundwater flow. Special situation or elective failures include direct tile drainage, straight pipes to streams and midnight pumpout of holding tanks. It also includes the contamination of an entire aquifer by excessive on-site system loading. Nitrates are one of the most significant pollutants in cases of well contamination. Phoshorus has little direct public health impact, but is well known as a major factor in lake and stream enrichment. Bacteria and viruses usually enter bodies of water through overload flow. Failure sensing methods include: interview and inspection; aerial photography, septic leachate detectors, and groundwater flow meters. Using the new sensing approaches it is now possible and cost-effective to determine which of a group of on-site treatment systems may be causing water quality problems, and if an areawide problem exists.

Dredge and fill operations in some waters are subject to section 10 of the 1899 Rivers and Harbors Act supervised by the Army Corps of Engineers, who share supervisory responsiblity for section 404 with the EPA. Section 404 states that consideration must be given to the need for the proposed discharge and the availability of alternative sites and methods of disposal that are less damaging to the environment. Chemical and/or bilogical testing of material proposed for discharge may be required in order to assess the impact of disposal.

Water samples were collected from the Ohio River at Huntington, West Virginia during the period 4 December 1978 through 29 January 1979, and from the Schuylkill River at Philadelphia, Pennsylvania during the period 27 November 1978 through 24 February 1979. The Schuylkill River water contained chloroform ranging from zero to 13.5 ppb. Eleven additional compounds occurred at < 1 ppb values. The Ohio River water contained nine identifiable compounds with all the compounds present below 1 ppb with the exception of chloroform, which ranged from zero to 3 ppb. No non-halogenated compounds were found in either river, with the exception of toluene in one Schuylkill River sample. Among the most prominent compounds found in both rivers were: chloroform, carbon tetrachloride, trichloroethylene, tetrachloroethylene, and 1,1,1-trichloroethane. Cyclical patterns can be seen which indicate some contamination whose source has yet to be determined.

By the year 2000 the market for desalting in the U.S. is expected to be over 29 billion gallons per day. Distillation, freezing, reverse osmosis, and electrodialysis are currently used methods of desalting. Factors influencing the effectiveness of each process include plant location, energy and its availability, feedwater type, and available brine disposal methods. Freezing and distillation are the preferred methods for desalting water with a high salt concentration. Multi-stage flash distillation, which is commonly used, has a continuous cycle to make maximum use of energy but problems occur due to scaling and fouling. Three major steps are involved in desalting by freezing: partial freezing to form an ice-slurry, separation of ice crystals from brine, and melting the ice. Freezing cannot currently desalt large quantities on an economical basis. Electrodialysis uses a cell pair with different types of ion-selective membranes and a direct current to cause ion migration. In reverse osmosis, also a membrane desalting process, pressure is applied to the salt water side of a semipermeable membrane causing fresh water to flow through the membrane. All of the processes generate brine wastes that are disposed of in a variety of ways.

The provisions of the act gave a good indication of the viewpoint many held at the time as to the solutions to our water pollution problems. Those provisions were overwhelmingly oriented towards point-source control. The keystones of the Clean Water Act were The Grants Program for Construction of Municipal Sewage Treatment Facilities under Section 201 and the National Pollutant Discharge Elimination System Permit Program under Section 402. Nonpoint sources were also considered of concern, but certainly not of equal importance. Control of these sources was left to the voluntary use of best management practices to be developed under Section 208 Water Quality Management Plans. Research done in part under Section 208 has shown clearly just how important nonpoint source pollution control was, and stormwater runoff, particularly in urbanzied areas, was found to be one of the most widespread and difficult of the nonpoint sources. The authors suggested that researchers and policy makers need to appeal to the average citizen by educating them about the problems and various solutions related to control of stormwater runoff. Stormwater could be made into a resource that can actually enhance their health, safety, and recreational activities. (See also W90-01919) (Mertz-PTT) JF - Stormwater Management Alternatives.

Ongoing efforts to improve and refine predictive mathematical models impose another need for extensive water quality information. The second successive intensive monitoring program in the Potomac Estuary was performed during the period July to September 1978. This program consisted of three distinct elements: slack tide sampling over a 65 mile reach of the upper estuary; sampling of the effluents at the eight major wastewater treatment plants in the Washington Metropolitan Area; and special field and laboratory studies which addressed specific aspects of the dissolved oxygen budget for mathematical modelling purposes as well as the chronic problem of eutrophication. The 1977 study occurred under low flows whereas the summer of 1978 was characterized by higher and more erratic flows, which were a major driving force in terms of water quality behavior. Comparing the 1977 and 1978 ambient N:P ratio data reveals that their rate of spatial decline, or the tendency for nitrogen to rate limit algal biomass production, appears to be a function of the bloom size as measured by chlorophyll a. Chlorophyll a concentrations in the Potomac during 1978 were low in comparison to 1977 observations and had considerably less variability. In September, blue-green algae comprised approximately 80% of the total population, and 87% of the blue-green population was identified as Pseudanabaena catenata. Blue Plains still constitutes, by far, the largest single point source in the Washington Metropolitan area, accounting for 85% of the BOD5, 77% of the TOC, and 58% of the inorganic PO4.

The 96-hour median lethal concentrations were 18 mu g/liter for copper, 1,104 mu g/liter for cadmium, and 3,693 mu g/liter for zinc in 12 C water. These values, when compared to those for chinook salmon and steelhead parr tested under similar conditions, show that the northern squawfish are more tolerant than the two salmonids to zinc and cadmium but equally sensitive to copper.

There were wide variations in chemical compositions, but all contained heavy metals, organic chemicals, and nutrients. Algae, particularly Selenastrum capricornutum (freshwater) and Selenastrum costatum (estuarine), were most responsive to all wastes; some effluents were stimulatory at concentrations of less than 1% but inhibitory at concentrations greater than 50%. Overall, 61% of the effluents were toxic to Daphnia pulex, 40% to fathead minnows (Pimephales promelas), and 53% to grass shrimp (Palaemonetes pugio) and sheepshead minnows (Cyprinodon variegatus). There was no obvious relationship between biological effects and the many parameters of effluent quality. Both growth stimulants and toxicants were present in some wastes. The impact of complex wastes on aquatic systems was calculated using the discharge rate and the LC50, EC50, or SC20. Thus Waste X with low SC20 and high discharge rate was judged most toxic of the group. Waste W, with a low SC20 and low discharge rate, had a low potential for adverse effects.

Adjustments are suggested to bring the estimates and actual costs closer. Water quality produced by most direct filtration plants is satisfactory, meeting the 1 NTU limit. Although some raw water turbidities are very low, it is not desirable to omit the coagulation step, which removes Giardia cysts and asbestos fibers.

The history of federal water pollution control legislation is recounted, with emphasis on the October 1977 policy statement, its relationship to the Clean Water Act, and recent construction grants program guidance on land treatment. A November 1974 memorandum put EPA on record as preferring land treatment when cost effective and environmentally acceptable. AT the time of the October 1977 policy statement, EPA issued (with the Corps of Engineers and the Department of Agriculture) the ' Process Design Manual for Land Treatment of Municiapl Waste water'. Recycling, reclamation, and reuse are basic policies outlined in the Clean Water Act of 1977. This act offers incentives to those who choose to implement alternative and innovative technologies, including land use.

It was possible to replace all the makeup water with cooling water blowdown containing up to 690 ppm Na+ (for low-sulfur coal) when operating under appropriate conditions (less than 2500 ppm SO2 in flue gas at a Na+ level of 15,000 ppm in the scrubbing liquor or 3000 ppm SO2 and 8000 ppm Na+). By integrating the water treatment system into the FGD, rather than into the cooling water blowdown stream, water recovery was increased 50% because the FGD scrubber preconcentrates the blowdown prior to water treatment. In addition, the evaporator produces high-quality condensate usable as boiler makeup water.

The half-liter proportional diluter uses positive pressure, with its primary siphons being activated by a pulse of pressure instead of by a partial vacuum as in conventional diluters. The need for venturi tubes, vacuum manifolds, and individual water blocks is eliminated by the device. Pressure is delivered through air cylinders, air compressor lines or air pumps. Performance evaluations of the diluter were conducted in 96-hour acute toxicity tests to the grass shrimp, Palaemonetes pugio, exposed to the organochlorine pesticide, endrin, or the carbamate pesticide, sevin. Recoveries of the pesticides from seawater samples wer greater than 90%. Other advantages of the proportional diluter include its ease of construction, calibration and cleaning, its low cost, compact size, and albility to conserve water.

At present, 73 of the 106 standard metropolitan statistical areas cannot provide secondary treatment for all their flows. The remaining 33 could, but do not consistently provide secondary treatment due to overloading or operation-maintenance problems. Other immediate priorities are innovative and alternative technology and help for small and rural communities. Turning the program over to the states, thus providing local responsibility for operation and maintenance, is also high on the priority list. A prime need is for stability of funding, which will allow orderly planning, prevent program starts and stops, and assure states of money needed to finish projects once they are started.

The town issued a public notice which recommended that all water used for drinking or cooking be boiled. Also, plans were made to either tap another aquifer or treat and monitor the contaminated aquifer. Since the contaminated levels were not abating and the source remained undetermined, it was decided to use TCE-removal techniques for the existing system. Granular activated carbon (GAC) was excluded due to its high cost. Aeration was used successfully to remove TCE.

This paper shows by simulation analysis that random grab samples are as effective as composite samples for monitoring purposes and provide more information on plant variability. In addition, by using a constant volume compositing regime, a single composite of n subsamples provides as much information as do n grab samples. Monthly average performance measured by M composites is the same as that measured by M random grabs taken over the same period. M grab samples are equally or more informative than the monthly average derived from flow proportional composites. For judging average plant performance, composites are better than grabs; for long term performance, grabs and composites provide the same real information. Process extremes, particularly high values, are more readily revealed by grab samples than by composite samples. This allows earlier corrective measures for out-of-control plant operations and warnings on releases of momentarily high concentrations of toxic or high BOD effluents.

Pipe loop tests were also conducted. Loose asbestos fibers were found in waters with agressiveness indexes up to 10.48, but not over 11. Pipes in systems with agressive water (index under 10) showed visible deterioration, except for one, which was coated with an iron rust-like material. Agressiveness index, pH, alkalinity, and hardness, considered singly, were not sufficient to predict the presence of loose asbestos fibers or pipe deterioration. Metals such as Zn, Fe, and Mn appeared to have a protective effect on pipe walls at the low temperatures common in water distribution systems.

The activated sludge process can biologically convert ammonia to nitrite and nitrate by nitrification. Favorable temperatures for nitrifying bacteria are in the range of 5-30 degrees, with more efficient processing occurring in the summer than in the winter. Dissolved oxygen conditions in aeration tanks should be maintained at 2.0 mg/liter or above, and the optimum pH for nitrification is 8.4 and should not fall below 7.0. To require nitrification, the ammonia nitrogen concentration of an influent waste water should be more than 1 mg/liter at all times. Toxic metals and organics may also interfere with the nitrification process. Conventional activated sludge processes are usually well suited to biological nitrification. Contact stabilization is generally not adequate for nitrification, because insufficient biological mass in the contact tank often produces incomplete removal of ammonia by the floc.

Both human and aquatic health assessments involve extrapolating results of observable responses in test species to projected or acceptable levels in the species of concern. Certain practical differences exist between human and aquatic risk assessment. Human health hazard assessment attempts to convert a risk from various mammalian species to only a single species. Aquatic hazard assessment is concerned with the effect of xenobiotic stress in aquatic communities, groups of species interacting by mechanisms which are neither readily quantified nor clearly understood. Information on sources of exposure, pharmacokinetics, and adverse effects must be carefully evaluated. Source data is essential to determine the contribution of exposure from water relative to all other sources. Pharmacokinetic data allow extrapolation and characterization of the mode of toxic action. Toxic effects information includes data on acute, subchronic and chronic toxicity, mutagenicity, teratogenicity, and carcinogenicity. A distinction must be made between threshold and nonthreshold effects. For carcinogens and mutagens criteria are calculated by postulating an acceptable increased level of risk and using extrapolation models to estimate the dose which would result in these increased levels of risk. For other chemicals, thresholds are assumed and criteria are calculated by deriving acceptable daily intakes.

The extent to which indicator bacteria and some viruses are destroyed by anaerobic mesophilic and thermophilic digestion of domestic wastewater sludges as these sludge stabilization processes are currently practiced is also examined. Large variations were found in the numbers of viruses occurring over narrow ranges of numbers of fecal coliforms, total coliforms, and fecal streptococci in raw sludges and in mesophilically and thermophilically digested anaerobic sludges. This finding suggests that the bacteria were poor quantitative reflectors of the numbers of the viruses detected. All three indicator bacteria were destroyed more rapidly than were the viruses by mesophilic and thermophilic digestion of the anaerobic sludges. The relative rates for the destruction of viruses, fecal coliforms, and fecal streptococci in the digested sludges were consistent over the 17 month study. Fecal coliforms were 7 to 8 times more sensitive than the viruses to mesophilic digestion and 9 to 10 times more sensitive to thermophilic digestion. Even more sensitivity was noted among the total coliforms. The rates at which fecal streptococci were destroyed by mesophilic and thermophilic digestion of anaerobic sludges approached those at which the viruses were destroyed by those processes. This suggests that rates of fecal streptococci destruction may be used as indicators for the rates at which viruses in sludges are destroyed by these processes.

Conditioning was to a criterion that required 80% of the fish to leave the 'home' area and reach the 'reward' area within 2 minutes of release. Challenges were at successive 3 C increments above acclimation or the previous challenge temperature. Fish were first observed to delay their entrance into the intervening heated water at challenge temperatures of 12-15 C above acclimation. At each increment above 12-15 C over acclimation temperature, delay in transit increased; however, complete group inhibition was never achieved. Above their critical thermal maximum (CTM) the reward was achieved even at the expense of deaths among the achievers. Responses were the same whether fish were challenged individually or as groups. Fish exposed to their CTM without prior challenges at less stressful temperatures responded similarly to those receiving progressively greater challenges.

The Gramm amendments (HR-4509) would change the burden of proof in setting standards, suspend standards that have been on the books for almost 20 years, reduce measures to limit human exposure to carcinogens, and provide a loop-hole for oil- and gas-exploitation related ejection wells. These amendments are attempts to avoid excessive government regulations and unnecessary increases in utility bills. It was the unequivocal intent of the Congress in the Safe Drinking Water Act to protect the public health. EPA has responded to this intent by controlling trihalomethanes in drinking water to provide public health protection to the vast majority of Americans, who use public water. EPA is also investigating other potential problem chemicals: trichloroethylene, carbon tetrachloride, tetrachloroethylene, 1,1,1-trichloroethane, and 1 ,2-dichloroethane. The issue of protecting public drinking water is more complex than it was a few years ago. Economic impact, cost-benefit analysis, and energy issues must now be considered when implementing the Safe Drinking Water Act.

The health effects of Ba and radionuclides are briefly reviewed. Two-stage coagulation removes about 70% of Ba but is too expensive for practical purposes. Ion exchange and lime precipitation are two effective softening techniques for Ba removal. Powdered and activated carbon are ineffective for Ba removal, while electrodialysis and reverse osmosis show promise for Ba as well as hardness removal. Radium is best removed from drinking water by methods effective for Ca and Ba. The lime and lime-soda ash softening techniques of Ra removal show a pH dependence, with better removal at higher pH. Cation exchange resins will remove many cation radioisotopes, while anion exchange resins will remove anion radioisotopes. The major considerations in selecting a treatment method are the economics , which involve capital and operating costs and depend on the design and size of the facility.

On the state level, a study carried out in North Carolina by the Legislative Commission on Alternatives for Water Management yielded the conclusion that regional water management has many benefits and can be organized in two ways: A state water authority could develop water supplies and provide wholesale supplies to local governments, or a river basin commission could be created in each of the state 's major river basins which would have water management responsibilities and some taxing or revenue-raising powers. Another priority on the state wells is for the legislature to review the future of the Clean Water Bond program, so communities know what funding they might expect. On the federal level, President Carter 's water policy incorporated water conservation regulations and incentives in almost all federal programs that have any impact on water supply or water storage. The current picture on water policy is uncertain because there is a difference of opinion as to the value of grants to local agencies. One view is that local agencies need to be self-sufficient. Another is reflected in the Domenici-Moynihan bill, S.1641, which provides flexibility on the state level and perhaps less red tape in Washington. The paper reviews pending legislation in Congress and possibilities for federal funding of local projects, as well as changing attitudes about various approaches to water management at the federal level.

New analytical procedures have been formulated to meet this mandate, and quality assurance (QA) and quality control (QC) programs have been devised to provide data on the precision and accuracy of the analytical results. QA procedures encompass the total program which ensures the consistency and reliability of results. QC procedures are collective routine actions taken to provide QA in the laboratory. A QA/QC plan was designed for the Organic Chemicals Branch which had placed upon it a 2-wk period for method refinement and a rapid turnaround of samples during a 3-day sampling episode to simulate heavy workload conditions. Spiking and recovery studies were repeatedly employed to overcome the problems of variability in waste waters. The program was composed heavily of QA measures, but the quality of the generated data was known by the end of the study. Changes in the objectives or use of the data would necessitate changes in QA formats. Other programs may not require such QA measures, so before a QA/QC plan is initiated, available resources and projected use of data to be generated should be carefully considered.

The strict liability provisions of section 311(b) (6) of the Federal Water Pollution Control Act, now the Clean Water Act , were upheld in two cases. Certain actions by the Army Corps of Engineers were upheld under section 111 of the 1968 Rivers and Harbors Act, which authorizes the Corps of Engineers to investigate, study and construct projects to prevent or mitigate shore damage attributable to federal navigation works. Citizens for a Better Environment v. Environmental Protection Agency (EPA) involved a challenge to the federal EPA administrator 's approval of Illinois ' program to administer the National Pollutant Discharge Elimination System (NPDES) within the state. The Court found the Illinois scheme deficient in that it failed to provide for adequate citizen participation.

Radioisotopes (99-Tc, 131-I, and 72-Ga) are used in nuclear medicine for the diagnosis and treatment of certain diseases. In laboratories, radioisotopes (3-H, 125-I, 57-Co, 59-Fe, and 14-C) are used for patient diagnosis and in research. Low level radioactive wastes, both solid and liquid, are generated by these uses of nuclear materials and require disposal. In Vermont, at present, the only radioactivity released by sewer discharge to the environment from nuclear medicine activities is that which is contained in patient excreta which are exempt from US Nuclear Regulatory Commission (NRC) controls. All other radioactive wastes from nuclear medicine facilities are disposed of by use of decay storage and/or shipment to one of the nuclear wastes disposal sites. In clinical laboratories, in-vitro procedures are done under authorization of a general NRC license. In some cases, all materials are disposed of by decay storage and/or shipment to one of the nuclear waste disposal sites. In other cases, liquid wastes are dumped into sanitary sewers. An inventory of all radionuclides currently being used by the facilities in VT utilizing sewer discharges was conducted. The amount of each radionuclide being discharged daily from each facility was then determined. Once the radionuclides were discharged, the activity of each radionuclide was reduced if the transit time in the sewer and detention time at the sewage treatment plant exceeds the half-life. It was found that 5 hospitals and 1 college disposed of radioactive waste material into sewer collection and treatment facilities which discharged into streams flowing into Lake Champlain or directly into Lake Champlain itself. In all instances, it was found that the radioactivity of the discharges immediately downstream of the sewage treatment plant did not exceed the US EPA's standards for radioactivity in drinking water.

Under the Toxic Substances Control Act, this information must be provided before new chemicals may be marketed. The subroutines include sedimentation, coagulation-flocculation (2 versions), filtration, aeration (2 versions), chemical oxidation, and granular activated carbon adsorption treatment. The chlorination model needs further experimental data and, in all probability, chemicals will need to be modeled on an individual basis. If the number and distribution of the population at risk and the necessary human and toxicological data are available, the potential health hazards of exposure to a chemical can be assigned. A sample run shows the removal rates for 11 selected chemicals: p-cresol, quinoline, methyl parathion, benzothiophene, 9H-carbazole, benzoquinoline, dibenzothiophene, 7H-dibenzocarbazole, benzoanthracene, benzopyrene, and mirex.

Inspections were conducted in 1974-1979; reports were analyzed from 100 municipalities in Illinois, Indiana, Ohio, and Minnesota, with treatment plants serving from 10,000 to more than 100,000 inhabitants. Daily per capita loadings for flow, BOD, and suspended solids were about 40% higher than values reported in standard engineering texts. Statistical analysis produced the following values (mean of 100 plants): flow, 166 gallons per capita per day; BOD5, 0.203 lb per capita per day; and suspended solids, 0.246 lb per capita per day. Comparable data from the literature were: flow, 58-135 gallons per capita per day; BOD5, 0.1-0.2 lb per capita per day; and suspended solids, 0.08-0.23 lb per capita per day. Increased use of garbage grinders may account for the increase in suspended solids loadings. (Cassar-FRC) JF - Public Works Vol 111, No 1, p 52-53, January, 1980. 3 Fig, 2 Tab, 6 Ref.

Some of the compounds tested are formed by chlorine biocides in cooling waters. Chloroform, bromoform, ethylene bromide, phenol, 4-bromophenol, and 2,4,6-trichlorophenol at concentrations up to 2.0 mg per liter did not affect C14 uptake by phytoplankton. Trichloroethylene stimulated C14 uptake at 0.5 to 1.0 mg per liter. Tetrachloroethylene inhibited uptake slightly at 2.0 mg per liter. C14 uptake expressed as % of control for concentrations of 0.5 to 2.0 mg per liter of other organic compounds were as follows: 2,4,6-tribromoanisole, 81-76%; 4-chlorophenol, 97-94%; 2,4,6-tribromophenol, 96-89%; pentachlorophenol, 39-2%; and pentabromophenol, 4 to -1%. Further tests with the two most toxic compounds, pentabromophenol and pentachlorophenol, at concentrations of 0.125 to 2.0 mg per liter showed that mixed phytoplankton were more sensitive to the chemicals than four individual phytoplankton cultures. Haloamines produced by metering NaOC1 and NH4Cl into the aquaria were more inhibitory than either chemical separately. Chloramine T was not inhibitory to photosynthesis.

Based on experience with evaluating treatment processes, the following five unit treatment processes were used in this investigation: steam- or air-stripping, oil/water separation, filtration on diatomaceous earth or dual media, biochemical oxidation, and activated-carbon adsorption. These suggested potential treatment processes were separately applied to treatment models for each pollutant considered. Steam stripping possibilities are determined by the boiling point of the organic contaminant. Oil-water separation is a good procedure for compounds having relatively low solubilities in water. Separation is achieved by means of API separation or dissolved air flotation. Filtration is used for compounds having low water solubilities and tending to be highly adsorptive on particulate matter, organic or inorganic. Biochemical oxidation can reduce an influent concentration of about 100 mg/liter for phenols to an effluent concentration of 50 micrograms/liter, maximum. Carbon adsorption is particularly effective for compounds of higher molecular weight, lower polarity, increasing hydrocarbon unsaturation, and aromatic structure. Pollutant solubility in water may be associated with entropy, which opposes the driving force for removing the substance from water. This is particularly evident when phenolic and nitrogen-containing compounds are considered. (Baker-FRC) JF - Environmental Science and Technology Vol 14, No 1, p 28-31, January, 1980. 6 Tab.

In the first experiment the recirculating static model ecosystem was used. In the second experiment a continuous dosing system was designed to demonstrate the effect of direct application of trifluralin into the ecosystem. In both experiments organisms were sampled 1, 3, 7, 15, and 30 days after the start of the experiment. In the first experiment the amounts of trifluralin available for accumulation by the organisms depended on the rate of desorption from the soil. In the second, the actual water levels obtained were 0.8, 2.5, and 21.6 ppb in the 1, 10, and 100 ppb treatments , respectively, by day 30. The data indicated extensive variation that can be obtained when using different model ecosystem designs in studying the behavior of pesticides in the aquatic ecosystem. These differences were probably related to the rapid metabolism and degradation of soil-incorporated trifluralin in the first experiment and to the continuous input of trifluralin in the second experiment. A very important difference between the two ecosystems was the toxic effect of trifluralin on the algae and fish during the second experiment. It is concluded that the risks of trifluralin in the aquatic ecosystem are greatest when there is a continuous input of trifluralin. With occasional soil-incorporated input, the degradation processes would minimize the risk.

AN - 15472356; 281047 AB - This study documents the effects of short-term (24 h) sublethal copper exposures on undirected swimming activity and photobehavior of B. improvisus stage II nauplii. All Cu treatments were static, with temperature and salinity conditions at 20 degree C and 15 or 30ppt. The 24 h LC sub(50) estimate for Cu is 88 ppb at 15ppt. and > 200 ppb at 30ppt. Sub-lethal Cu concentrations cause reductions in swimming speed, which decrease progressively with increasing Cu dose. At 50 ppb Cu, this was significant primarily at light intensities below the phototactic threshold. At higher Cu concentrations, significant reductions in mean linear velocity occurred at most light intensities tested. At 30ppt., 50 and 100 ppb Cu also reduce the positive photatactic response and 150 ppb Cu causes reversal of phototaxis at optimal intensities. Swimming speed and photobehavior show promise as sensitive behavioral indicators of copper toxicity. JF - Marine biology.

Cadmium accumulation increased with increased concentration of cadmium in seawater; greater amounts were accumulated during the summer months. Uptake patterns measured as cadmium content were similar among the total soft parts, gill, mantle and visceral mass. A continuous increase of cadmium concentration in the visceral mass was observed. This differed from the uptake patterns observed as cadmium concentration in gill, mantle and total soft parts. Although cadmium accumulation in the total soft parts and the tissus was curvilinear over the entire study period, significant linear relations between cadmium concentration and time indicated a general increasing trend. At seawater temperatures below 6 degree C, when oysters were not actively feeding, cadmium concentrations in the total soft parts varied significantly between treatments, but not within treatments. During spawning, cadmium concentration in the total soft parts increased, whereas the content decreased. JF - MARINE BIOL. AU - Zaroogian, GE AD - Environ. Res.

Jointly sponsored by four federal agencies--the Environmental Protection Agency, and the Departments of Commerce, Housing and Urban Development, and Transportation--the Clean Air Program conducted five regional Clean Air Conferences which brought together representatives from the public and private sectors to discuss air quality problems. The Final Report is a list of recommendations to the federal agencies involved as to how they can better assist cities in meeting the requirements of the Clean Air Act. In short, the recommendations state that better cooperation and communication will be the key ingredients in assisting cities in establishing their clean air programs. Better coordination is needed not only between the federal and local governments but also among the federal agencies themselves. In addition, local governments must be part of the decisionmaking process. Finally, new approaches to resolving clean air problems must be given more attention by federal, state, and local governments. JF - ENVIRON. PROFESS.

At speeds below 35 miles per hour (approximately), traffic noise is dominated by noise generated by the vehicles from mechanical, aerodynamic and combustion process phenomena. It is not until speeds in excess of 35 miles per hour (approximately) are reached that noise due to tire/roadway interaction becomes prominent and dominates the traffic noise spectrum. Since motor vehicle speeds in urban areas typically are less that 35 miles per hour, relief from traffic noise that interferes with human activity most accrue from reduction and/or control of noise created by the vehicles themselves. Studies conducted to identify and characterize motor vehicle noise show that engine exhaust noise dominates the sources of vehicle noise. Accordingly, degradation of exhaust system components, which otherwise muffle engine exhaust noise is the main cause for the escalation of overall vehicle noise. JF - IN "INTER-NOISE 80".

Dieldrin residue levels in environmental substrates, which are indicative of aldrin or dieldrin use, have decreased significantly since the mid-1960s, the peak usage years. However, human tissue studies do not show a corresponding decline in dieldrin residue levels. Thirteen studies, conducted between 1963 and 1976, show that average dieldrin levels in human adipose tissue and human milk fat remain between 0.160 ppm and 0.220 ppm. Other studies suggest that an equilibrium exists in the distribution of dieldrin among various tissues in humans, including blood, fat, brain, and liver. This relationship indicates that the concentration of dieldrin in any tissue may be used as an index of total body burden. JF - PEST. MONITOR. J. AU - Ackerman, L B AD - US EPA, Off.

The Agency's ability to assess hazard as required by law depends in part on test data developed through testing standards in Agency regulations. In reviewing the Agency's actions in this regard, the courts emphasize the importance of reasoned regulatory decisions. The legal requirements to assess risk and provide reasoned decisions in this regard establish the legal importance of testing guidelines and test data, and indicate that should test methodology is as important legally as it is scientifically.

Passive unloading effects are not significant in the long term in areas where mass loading is typically small. A significant seasonal difference in passive loading occurs with a higher percentage of passive loading taking place in the summer. The impact of passive loading can be minimized by reducing the number of days of passive exposure. Additionally, devices are available which can be attached to a hi-vol which effectively eliminate passive loading. JF - J. AIR POLLUT. CONTR. ASSOC.

A total of 20 human subjects were exposed to 100 mu g/m super(3) (0.033 mu M) sulfuric acid aerosol (0.5 mu m mean mass diameter) for 4 hr/day for 2 consecutive days. A total of 17 human subjects were exposed to 4 hr of ambient air on both exposure days. The chemical blood parameters were measured pre- and post- exposure, and 20 hr after the second exposure: serum glutathione, red blood cell glutathione reductase, red blood cell glucose-6-phosphate dehydrogenase, lysozyme, serum glutamic oxaloacetic acid transaminase, serum vitamin E, and 2, 3-diphosphoglycerate. The results indicate no significant response in any of the seven biochemical blood parameters measured. At this level, repeated exposure did not over-burden the upper airway defenses against acid aerosol. JF - ARCHIVES ENVIRON.

The general goal of CEAS is to assess the relative condition of marine coastal systems through the use of the edible blue mussel (Mytilus edulis , Linnaeus) as a biological indicator. The present program has evolved from a number of years of research devoted to assessing the utility of various environmental stress indicators along a known gradient of pollution from the highly stressed Providence River in upper Narragansett Bay, R.I., to the relatively unstressed lower Bay. The resultant CEAS approach utilizes groups of mussels from a single population which are placed in cages along a gradient of pollution. This provides a field research platform upon which laboratory-generated response parameters are being tested and verified. JF - RAPPORTS & PROCES-VERBAUX REUNIONS CONSEIL INT. EXPLOR.

The concentrations of PAHs in drinking water sources range from nanogram to microgram-per-liter quantities. Conventional treatment (flocculation, sedimentation, chlorination, and filtration) appears to substantially reduce total PAH concentrations present at higher concentrations in source waters. A major factor in this reduction is the removal of PAHs adsorbed onto particulate matter. The role of chlorination is not clear and reactions of PAHs with chlorine may in fact produce products which themselves are deleterious. Activated carbon can further assist in PAH removal. However, it may be inappropriate for treatment of PAHs present at low concentrations. Water entering the distribution system can become recontaminated via contact with reservoirs and pipes coated with coal-tar or asphalt based products.

They represented about 8.3% of the total E. coli population. Fifty-five strains, representing each of the 32 resistance patterns identified, were mated with an E. coli K-12 F super(-) strain. Matings were performed on membrane filters, and the cells were washed to remove any colicins produced by the donors. Thirty-one strains, about 5% of the mean E. coli) density in the samples, transferred drug resistance and, hence, possessed conjugative R plasmids. Of these, 80% transferred drug resistance at a frequency of about 10 super(-) super(4) or less. JF - APPL. AND ENVIRON. MICROBIOL.

Sampling was performed with three dichotomous samplers, a mobile laboratory containing instruments to measure gaseous pollutants, and two gas chromatographs for measuring halocarbons. Sulfate and its associated cations represented 61% of the particle mass. Of the total mass measured in the fine particles, elemental carbon accounted for 5% and organic carbon accounted for 10%. Crustal elements such as aluminum, calcium, iron, and silica were minor constituents of the fine-particle mass. During the period of the study the fine-particle aerosol in the Great Smoky Mountains was dominated not by natural organic compounds but by acid sulfates. JF - ENVIRON. SCI. & TECH.

Water consumption was slightly depressed in the highest dose group. A slight decrease in the relative weight of adrenals of treated vs. control animals was observed. Increasing dose, but not duration of exposure, produced related increases in barium concentrations in liver, skeletal muscle, heart, and bone, with the highest concentrations observed in bone.

Because of recent evidence outlining the role in pulmonary immune development of particle size and depth of mycoplasma deposition in the hamster lung, the authors developed an aerosol chamber for the reproducible aerosolization of radiolabeled M. pneumoniae . Organisms were labeled to high specific activity by the incorporation of super(3)H-oleic acid and aerosolized under airflow and humidity conditions creating a mean particle diameter of 2.0 mu m. Under these conditions, viable mycoplasmas were reproducibly and evenly distributed to all major lobes of the lung.

Using benzo(a)pyrene monooxygnease as a measure of mixed-function oxidase activity, it was found that phenanthrene-9, 10-quinone was the most active compound tested with a K sub(1) = 0.79 mu M. Phenanthrene-9, 10-quinone did not affect cytochrome c reductase but did inhibit aminopyrine N-demethylase and p-nitroanisole-O-demethylase in both 3-MC and PB-induced microsomes with almost identical inhibition constants. 1,2-Naphthoquinone exerted similar effects as phenanthrene-9, 10-quinone on cytochrome c reductase, aminopyrine N-demethylase and p-nitroanisole-O-demethylase.

This procedure and analogous procedures for non-lognormal concentrations implicitly assume that sequences of pollutant concentrations are stationary. However, air pollutant concentrations are nonstationary. In this paper it is shown that application of procedures, such as Larsen's that assume stationarity to a nonstationary sequence of concentrations can produce seriously erroneous results. Two methods for using air quality data to estimate the distributional properties of maxima of nonstationary sequences of concentrations are illustrated.

These discrepancies are much reduced when one considers the atmospheric photo-oxidation of the non-methane organic material released by vegetation. From known oxidation mechanisms it has been inferred that these photo-oxidations might be the largest single source of atmospheric carbon monoxide.

Forty-eight female rats were given one of four lead chloride drinking water solutions: 0.05, 0.58, 17, or 352 ppm lead. Two animals from each group were sacrificed after 3, 6, 9, 12, 15, and 24 weeks of treatment. Both femurs and the frontal and parietal bones of the skull were removed from each animal and analyzed for lead concentration. A significant accumulation of lead was observed in femurs and skull bones only from animals in the 352 ppm lead treatment group. The lead concentrations of the femurs were significantly higher than skull lead concentrations for all groups.

The system covers the infrared spectral region from 650 to 6000 cm super(-1) at a maximum resolution of 0.06 cm super(-1). In the absorption mode, many gaseous pollutants can be detected at parts per billion levels over a one kilometer path. In the emission mode, warm gases exiting industrial stacks can be detected at parts per million levels. The temperature of the stack gases can be determined directly from the spectra. This paper describes the interferometer system and results of recent measurements of jet engine, brick kiln, gypsum pond, and industrial stack emissions. JF - OPT. ENG.

A multi-variate analysis of variance indicated that testis, seminal vesicle, and preputial gland weights were significantly smaller as a result of Mn administration. These results support earlier observations of altered locomotor activity levels and reproductive development in male rats in the absence of other signs of toxicity. JF - J. TOXICOL. AND ENVIRON.

Overall, endrin was more toxic than methoxychlor. Asellus was the most sensitive to methoxychlor; methoxychlor had little effect on Hydropsyche during week 1, but during weeks 2-4 the LC50 decreased from 2.90 to 1.30 ug per litre; no stoneflies or snails died during exposure to methoxychlor, but overactivity in the former species occurred. The LC50 for methoxychlor at 28 days ranged from 0.42 to 4.23 ug per litre. The snail accumulated 13-25 times more methoxychlor than the stonefly, and 5000-8700 times more methoxychlor than the water concentration. The caddisfly was the most sensitive to endrin; the LC50 at 4 days was 0.34 ug per litre and then fell, with survivors only at 0.03 ug per litre.

This study was to determine the short-term lethal concentration and long-term effect of waste oil on the survival, growth and reproduction of the American flagfish, Jordanella floridae. The results are given in great detail, showing the maximum acceptable toxicant concentration for the water-soluble fraction of used crankcase oil was estimated to fall between 325 and 930 u litres per litre. It is speculated that heavy metals probably contribute significantly to the toxicity of the waste oil tested.

For samples which are not in equilibrium with the atmosphere it is recommended that they be kept under sealed conditions after collection and during pH measurement to eliminate meter drift caused by interaction with atmospheric carbon dioxide. While this procedure is not necessary in cases where equilibrium with the atmosphere is reached or there is a high buffer capacity it is suggested that it be used in all cases where drifting problems occur, to avoid equilibrium checks.

The LC50 values for the metals were, respectively, 16.3, 3.8, 36.8 and 258 ug per litre. Copper levels over 28 ug per litre and cadmium levels as low as 8 ug per litre resulted in 100 per cent larval deaths. At 80-100 ug per litre, zinc effected a 90 per cent mortality. At concentrations less than the LC50, no growth inhibition occurred. The LC50 values for Cu, Pb and Zn were up to 870, 250 and 1600 times lower, respectively, than those previously reported. The reasons are discussed, including susceptibility at particular life-cycle stages and species susceptibility.

It must be able to detect thermal and microbial stratification. Grid sampling will identify surface inputs of differing water qualities, pollution, run-off, etc. In situ measurements give a realistic survival determination of organisms. Data from such a sampling programme revealed several factors that could help protect source water quality.

The research reported is in four sections: field evaluation of 10 public water supply systems, pilot-scale tests under controlled conditions, bench-scale tests, and in situ rehabilitation of deteriorated pipe. It is found that asbestos cement pipe behaves much like any other piping materials except PVC, in that if aggressive water conditions exist the pipe will deteriorate and high fibre counts are likely; if the water is not corrosive, no deterioration problems arise.

A study of the size distribution of asbestos fibres indicates that the fibres produced by corrosion of asbestos cement pipe are generally longer than those produced by other means . Wastes discharged from the processing of iron ore, have contributed large numbers of amphibole fibres to parts of lake Superior supplying raw water to adjacent cities. Concentrations of chrysotile fibres of 100 million fibres per litre and over have also been recorded in piped water supplies from a number of U.S. cities, but the majority of consumers are not exposed to concentrations greater than 1 million fibres per litre. Susceptibility of asbestos cement pipes to corrosion can be predicted using the aggressiveness index which takes into account the pH, total alkalinity and calcium hardness of the water. Acid rain falling on asbestos roofs may also cause appreciable fibre concentrations in water collected in cisterns and used for domestic purposes in areas without piped water supplies.

Both gas and mechanical mixing systems were compared at MSW/MSS ratios of 9:1 and 3:1. Gas mixing was generally inadequate and resulted in a high build-up of volatile solids near the surface of the liquor. This scum layer could be more readily broken down with the aid of mechanical mixing equipment, but measurements of power consumption indicated that for effective control of scum on a commercial scale the overall energy balance was likely to be negative.

In vivo experiments were carried out on 8- to 10-day old larvae in seawater dosed with bromodeoxyuridine and the mutagen mitomycin C(MMC). Since the species has 18 large chromosomes, is easily cultured, is a benthic species and forms part of the food web for commercially important fishes, it may be a useful model for studying the effects of genetic toxicants in marine environments. Certain difficulties with the assay, are pointed out.

The background, chemical or peak-shape interference in the determination of these two heavy metals is suppressed: both Mo and La decrease chemical interference and interference from uncompensated background resulted in a high stability through formation of a stable interstitial carbide. In routine determinations, the mean analyte recoveries were 90-110 per cent for both Cd and Pb, with peak height reproducibility of 2-3 per cent. The Mo and La treatments may be useful alternatives to other types of treated graphite atomizers.

The particular role of micro-organisms in these transformations is considered as it affects the persistence of chemicals in the environment. The general philosophy of the U.S. regulatory authorities in their evaluation of these effects is reviewed, and some areas of particular uncertainty are examined, such as the correct choice of inocula, media and substrate concentration in order to achieve results which truly reflect those in the real environment. Certain types of micro-organism are also viewed as essential to the decomposition of commonly occurring waste products, releasing vital nutrients in the process, and the protection of such microflora against harmful effects is therefore of major importance. Test methods should therefore include procedures for assessing the response of such organisms to synthetic chemicals. JF - Aquatic Microbial Ecology (edited by Colwell.

The reaction between monochloramine and the bromide ion was shown to follow first-order kinetics with respect to monochloramine, the bromide ion and hydrogen ion concentration over the pH range 6.8 to 8.2. The oxidation of bromide was considered to be the primary pathway for monochloramine removal in highly saline waters. A mixed haloamine, bromochloramine, was the main reaction product of the reaction between monochloramine and the bromide ion. The decomposition of monochloramine in marine waters may produce a less toxic discharge since bromochloramine is chemically less stable than monochloramine. The disappearance of monochloramine in highly saline waters (33.6 per thou) follows the rate of bromide oxidation by monochloramine.

A typical landfill is postulated with three generalized aqueous environments: an aerobic zone, without hydrogen sulphide, containing soluble arsenate, insoluble ferric hydroxide and adsorbed arsenate; an anaerobic zone, without hydrogen sulphide or oxygen, containing very toxic arsenite and soluble ferrous iron, and where mobility of arsenic is maximal; an anaerobic zone, with hydrogen sulphide, containing insoluble iron and arsenic sulphides and metal sulpharsenites. The importance of iron in these systems and the fact that the arsenite ion is about 60 times more toxic to humans than arsenate, are emphasized.

Methyl paraoxon did not depress the enzymatic activity in surviving shrimp after exposure for 74 hours to 0.98 ug per litre. In vitro, exposure of the excised ventral nerve cord resulted in complete inhibition after exposure for 1 hour to 60 mg per litre methyl parathion, or 300 ug per litre methyl paraoxon. Acetylcholinesterase versus death was considered not to constitute a direct relationship in shrimp, and the degree of enzyme inhibition in the ventral nerve cord of shrimp captured from neutral waters is not a reliable or accurate predictor of levels of water pollution.

The feasibility of using cooling tower blowdown in place of clean water as make-up for the scrubbers was established and the additional benefits of vapour compression evaporators in the recirculating system were also evaluated. When the flue gas scrubber is allowed to function as an evaporator preconcentrating blowdown prior to its introduction to a vapour compression evaporator, a 50 per cent increase in the quantity of water recovered can be achieved, while producing sufficient high-quality condensate to meet the demands for boiler make-up water.

The results lend high statistical assurance (70.99) to the hypothesis that the LC50 value of Aquazine to fish is greater than 180 mg per litre in both hard and soft water. The large differences in LC50 estimates suggests that the presence of an additive in the formulation and differing fish handling procedures may have caused the different results.

The 96-hour LC50 was 2.06 ug per litre and a 28-day exposure to an estimated concentration of only 0.075 ug per litre decreased the production of offspring from females. Data from chronic exposure test also indicated not only reproductive impairment in the parents but also in the progeny, an effect which persisted after a recovery period in water containing no dimilin. The occurrence of these toxic effects at parts per trillion concentrations indicate that the presence of traces of dimilin in estuaries could have serious effects on the juvenile stages of a wide range of non-target organisms.

The immediate survey is followed by regular monitoring at prescribed intervals to evaluate chronic effects. The scope of the method and its application in practice are described with reference to the Peck Slip oil spill off the northeast coast of Puerto Rico and the attendant pollution of mangrove forests along the coast. In addition the concept of a vulnerability index is developed as an aid to pre-spill contingency planning and some examples of its application are given, especially in the Cook Inlet portion of the southern Alaskan coastline.

Each ecosystem consisted of 10 parallel sand-filled compartments supplied from a constant-head reservoir with provision for continuous injection of the test substance. Tests were conducted using several chlorinated organic compounds, as well as barite and a lignosulphonate drilling mud, and their effects were assessed by comparison of the numbers, species and phyla of benthic organisms present at the end of the tests. The effects observed were broadly consistent with the results of single-species tests, but the method is claimed to possess several advantages in allowing the effects on community structure, on species not normally tested and on changes in sediment structure, to be predicted more accurately.

The extended data have been used to derive a mathematical model for assessing the fate and transport of five common phthalate esters in simulated aquatic environments. It is shown that hydrolysis, biolysis, photolysis, volatilization and export can, under certain environmental conditions and ester properties, be competing processes. It is indicated that the higher molecular weight esters will tend not to undergo transformation. Export from the ecosystem appears to be the dominant process.

The results demonstrated enhanced susceptibility to infection in fish exposed to copper at 4.5 pp 1000 mil., and cadmium at 1.0 pp 1000 mil., while zinc, even at 99 pp 1000 mil., caused a suppression of the infection. Since the limit of 4.5 pp 1000 mil., for copper is well below the level normally associated with toxic response, further consideration of maximum acceptable toxicant levels for this metal may be desirable in view of the possibility that fish surviving an initial toxicant exposure may easily succumb to pathogenic micro-organisms.

The results, described with graphs and tables, show that there is no significant correlation between the chlorophyll a content of the algae and trihalomethane production. However, evidence was found which indicates that trihalomethane production is mainly influenced by chlorine reaction with algal by-products.

The technique is effective if the BOD time series follows the first-order model and the nitrification stage has been suppressed. The method requires an estimate of the reaction rate coefficient to start an iteration. Successive approximations are found until the difference between them is less than some specified error criterion. The technique has been extended to show how confidence regions for the parameter estimates can be easily determined. JF - Journal of Environmental Engineering Division.

The lead carbonate complexes, lead hydroxide monomers and polymers, lead hydroxides, lead carbonates and the free lead(II) ion, were considered. Results of pipe loop solubility experiments, at different carbonate concentration values, are presented. The model agrees well with these data and with previously published pipe coupon tests and precipitation data at high carbonate concentration. It is nevertheless considered necessary to correlate field observations with laboratory data and modelling, and to obtain a more thorough analysis of major solubility-controlling factors.

The microphotographs obtained showed definite evidence of weathering and exposure of asbestos fibres to abrasion and release in contact with water, both under field conditions and during laboratory tests. Energy dispersive X-ray analysis spectra also revealed that the surface could be chemically altered during contact with water, with release of asbestos fibres, although certain inhibitors (such as zinc chloride) when added to the water appeared to minimize this type of attack.

In addition, highly aggressive water flowing though asbestos-cement pipes can cause asbestos fibres to be released into the water. Analyses of drinking water samples from public utilities in areas randomly selected throughout the U.S.A. is reported. The results indicate that 16-18 per cent of the utilities have highly aggressive water that could be very corrosive. The computation of an aggressiveness index is explained and shown to be simpler than the Langelier saturation index. The Ryznar stability index, which gives a quantitative index of the amount of calcium carbonate scale that would be formed, is also outlined.

The occurrence of the pathogens in animals, as a potential source of infection is considered, supported by a 4 page table listing the reported findings for enteropathogenic strains of E. coli and various Salmonella serotypes and shorter tables giving the occurrence of Salmonella and Enteriobacteria in cold blooded animals, and Leptospira in animals. Worldwide a wide range of pathogenic organisms have been reported to occur, and methods and media employed for detection and isolation are discussed. Of recent concern in the Western hemisphere is the presence of the bacterium, Legionella pneumophila, the causative organism of Legionnaires disease, which was isolated from air conditioning cooling systems and also from non-epidemic related natural habitats in Georgia and South Carolina.

Statistics relating to such outbreaks in the U.S.A. are presented, indicating that the most commonly occurring form was giardiasis, due to transmission of Giardia lamblia; however in at least two major outbreaks of gastroenteritis (in 1975-76) the causative organism could not be identified. Guidelines for the investigation of such outbreaks have been published with a view to increasing the chances of isolation of the responsible organism. Other diseases are surveyed in turn, consisting of amoebiosis, cholera, hepatitis A, yersiniosis, viral gastroenteritis, and a few miscellaneous infections, including diarrhoea in members of a polar expedition who drank water from an Antarctic lake from which Klebsiella was later isolated.

A handbook of best management practices, entitled Stormwater Management Procedures and Methods has been published, and extensive use of the SWMM and STORM models has been made in Canada and the U.S.A. in order to calculate the quantity and discharge/time characteristics of stormwater flows. Other models including the effects of quality are also discussed for use where stormwater is discharged direct to a watercourse; examples are SWOPS, SWOHS, QQS and HLOAD. The impact of U.S. legislation (PL 92-500 and 95-217) on the design of stormwater overflows has been studied and estimates of the capital cost of compliance have been reported for numerous locations. The effects of trace metals on the composition of runoff and sediments have been assessed for catchments of different types, and the use of computer systems for correlating land use with peak discharge fluctuations is also considered. Possibilities of in-situ and separate treatment for stormwater flows are discussed, together with the effects of infiltration into sanitary sewer systems. References total 150.

The incidence of certain sewage related or waterborne diseases has been surveyed on the basis of epidemiological data, and comparisons between control and irrigated zones have been reported. A comprehensive report from a workshop on the legal and health implications of sewage sludge has appeared, indicating that the risks were low enough to permit further development and operation of municipal composting systems. The potential hazards of land application are also reviewed from the standpoint of pathogen survival (bacteria, viruses and parasites), trace organic contaminants, and inorganics, including heavy metals, especially cadmium accumulation. The indirect reuse of sewage effluent in water abstracted for potable supplies is also considered in the light of studies in the U.S.A., and the evidence for mutagenic and possible carcinogenic effects of concentrates obtained by reverse osmosis.

In one case, improved laboratory methodology resulted in the repeated isolation of Yersinia enterocolitica in chlorinated supplies which were reportedly free of total and faecal coliforms and enterococci. Other surveys, in semi-tropical areas, have found from 45-80 per cent of household tapwater samples failing the coliform criterion. Studies of the microbial populations developing in granular activated carbon filters installed for removal of trace organics have been reported, and comparative studies performed on alternative disinfection systems for small community systems. Problems of contamination following repair or replacement of components in the distribution system have also been discussed. Surveys of swimming pool waters indicated that a free chlorine concentration of 0.8 mg per litre was necessary; ozonation did not reduce chlorine requirements but did improve the aesthetic conditions.

Temperature-depth profiles in a nonpumping well are used to determine vertical groundwater velocities of the downward leakage of water recharging the aquifer which is overlain by semiconfining beds of clay-rich glacial drift. Calculated and observed depths of penetration (19 m) of the annual surface temperature wave, and demonstration of the thermal stability of the well, validate application of the theory, which uses a dimensionless parameter beta to relate curvature in temperature-depth profiles to the magnitude of vertical leakage. Generally, the magnitude of beta decreases as the depth interval L within the aquitard increases. The corresponding decrease in the vertical component of groundwater velocity accompanies a gradual coarsening with depth of the aquitard materials. Temperature differences over time at a given depth within a thermally stable well are found to be within the accuracy of the temperature measuring system. Analysis of variations in beta over time shows that the variability can be due to the limitations of the resolution (0.01C) of the temperature measuring system.

In the 96-hour acute test, a measured concentration of 1,400/ mu g/liter was lethal to 50% of the juvenile test animals. In the partial life-cycle test, we also investigated uptake of Diazinon by sheepshead minnows and effect of Diazinon on brain acetylcholinesterase (AChE) activity. Average measured concentrations in the partial life-cycle test were nondetectable (control), 0.47, 0.98, 1.8, 3.5, and 6.5 mu g of Diazinon per liter of seawater. Although the number of eggs spawned by continuously exposed fish was significantly reduced (alpha = 0.05) in all concentrations, no concentration tested significantly affected parental survival or fertility of eggs, nor were survival and growth of progeny affected in a subsequent 28-day test. Fish exposed to 0.47 mu g/liter spawned 22.6 eggs/female-day, or 69% of control production (32.8 eggs/female- day). The number of eggs spawned by fish exposed to 6.5, 3.5, 1.8, and 0.98 mu g/liter Diazinon was similar (14.9-17.9 eggs/female-day), averaging 45-55% of production by control fish. Egg production by fish that had been previously exposed to 3.5 mu g/liter did not change significantly following deputation for 23 to 31 days. AChE activity varied inversely with exposure concentration, fish in the highest concentration (6.5 mu g/liter) averaging 71% inhibition. The concentration of Diazinon measured in adult fish exposed to 1.8, 3.5, and 6.5 mu g/liter averaged 169 times the concentration measured in the water. Diazinon was not consistently detected (<0.05 mg/kg) in fish exposed to 0.98 and 0.47 mu g/liter. The maximum acceptable toxicant concentration (MATC) for sheepshead minnows continuously exposed to Diazinon, based on reduced fecundity, is <0.47 mu g/liter; the application factor (MATC / 96-hour median lethal concentration) is <0.0003.

The scientific basis for treating and the reuse/recycling of wastewater should give greater emphasis to ecology and the management of natural biological systems. Neither the technological problems of designing biological systems nor the political and institutional constraints facing their implementation should prevent the increased future use of aquaculture systems for wastewater treatment. Where these systems can be made to work they should offer effective solutions to the need for cost-effective, environmentally acceptable, and energy efficient wastewater treatment and recycle/reuse practices. In order to assist in encouraging greater use of these aquaculture systems for wastewater treatment, we need to make sure that the results of past and ongoing research efforts are effectively applied to innovative/alternative technology projects funded through the EPA Construction Grants Program.

Water conservation is defined in many ways such as wise water management or saving water at one place and time to make it available for more beneficial uses. In the past, Federal programs have often been too late, scattered, and uncoordinated. To change this the President has required that all Federal water programs be reassessed, reviewed, and examined for water conservation opportunities. Nineteen Task Forces are conducting this coordinated analysis of Federal programs and water policy. A Water Policy Coordination Group keeps the Task Forces on schedule and on track. Task Force 6A has compiled a preliminary report of information and recommendations from 87 Federal prograns. A matrix was developed to rank the recommendations for the 87 programs. Reclamation rehabilitation was ranked number 1, waste treatment management was ranked number 3, and water resources research was ranked number 14. This effort begun by Task Force 6A must be continued and expanded if water management is to make full use of Federal programs.

The central thesis is that utility managers must look at elements other than capital facilities costs in attempting to minimize the overall cost of water supply. The system operating costs of both areas increased dramatically over the 1965-1974 study period, with Fairfax County increasing its OM cost as a percentage of total cost from 65 to 70%, and San Diego 's increasing from 74 to 87%. Equations are presented which show that, over time, a utility 's operating costs represent an increasingly larger share of its budget. Support services are the most rapidly increasing portion of operating costs, with labor cost increases being somewhat less significant. A regression equation relates cost to labor wages and indicates that annual operating cost increases almost linearly with respect to increases in revenue-producing water, if labor wage rates remain constant. Conclusions indicate that operating cost elements, particularly labor productivity, have been ignored in considering a utility 's budget. Thus, utility managers are advised to think in terms of balanced capital investment designed to minimize total costs and not simply to minimize capital investment alone.

Environments and ecosystems have sustained large alterations, leading to reduced productivity and loss of prime fish and wildlife habitat. The Clean Water Act of 1977 Guidelines mandate the examination of practical alternatives to the discharge of dredged or fill material. A general evaluation determines the possibility of a chemically polluted sediment. ' Guidelines to Minimize Impacts ' are incorporated concerning the substrate, water quality, tidal fluctuations, currents, salinity and other characteristics. Particular attention must be given to minimize construction impacts to special aquatic sites, such as sanctuaries, refuges, wetlands, vegetated shallows and coral reefs. Based on the Factual Determinations which are made, the Corps of Engineers must decide if the proposed action is in compliance with the S404 Guidelines, and thus whether or not to issue the permit.

This statement is equally applicable to aquatic resources, which is basically why no economic value has been fixed for aquatic resources. Consequently, no amount of public compensation funding under current law is guaranteed to go to those in fact injured by water pollution until the valuation problem has been resolved. The existing body of law regarding damage assessment are examined, including the common law approach and several state legislative schemes. The probable consequences of implementing a natural resource assessment scheme based on established natural resource damage assessment procedures and valuation tables are explored. Special attention is paid to the case of Commonwealth of Puerto Rico v. SS Zoe Colocotroni and Senate bill 2083, the 1978 Oil Pollution Liability and Compensation Act, which would establish a strict liability scheme.

In several states, the planning is being performed entirely by area-wide agencies. To date, $225 million in Federal funds has been obligated for this program, and another $75 million is available in EPA Regional Offices for obligation. Of the 225 planning efforts that have been initiated, 114 are in or through the process of local government adoptions; 21 of these plans have been certified by the State; and two have been approved by EPA. From an EPA standpoint, the desire was to secure a long-term funding commitment from the Office of Management and Budget (OMB) for the program, and to increase the FY 1978 budget request. A total Federal cost of the program was projected as being $542 million for the period between fiscal years 1978 and 1983. These funds would cover activities under four major categories: facilities planning for municipal treatment works, urban stormwater runoff, pretreatment, and nonpoint sources. The greatest portion of funds would be used for nonpoint sources, followed by urban stormwater runoff. Significant changes have been made in revised regulations including procedures covering changes in designation of agencies. Regulations also cover the major transition that will occur in the 208 program over the next several years. EPA is also imposing a funding sanction beginning in fiscal year 1980--no planning agency, state or areawide, can receive any additional planning funds unless a portion of a previously approved 208 plan is being implemented. The regulations also require timely action by the states on the certification of plans, especially areawide plans. (See also W90-04338)(Lantz-PTT) JF - Water Problems of Urbanizing Areas.

It was found that the waste stream samples were not miscible in a simple acetic acid leach solution. The samples lumped, and all the samples formed globules, which sank or floated in the solution, depending on their density. The results of the analysis of the filtrate revealed heavy metal concentrations of less than 0.01 ppm. Chloroform was used in a test procedure designed to simulate codisposal of waste with municipal refuse. The addition of the chloroform to the sample solution caused the waste globules to break down. If allowed to settle, two layers formed, acetic acid solution and chloroform, waste layers. When mixed, the two layers blend, and better contact between the waste and the acetic acid solution is achieved. It can be seen from these results that the heavy metals were leached to the acid solution when chloroform was added. The values for crude oil and oil shale are relatively low , since the total metals in the sample were low. In the cases of organic paint sludge and cutting oil wastes, large amounts of leachable lead (386 and 1310 mg/L) were identified by using the chloroform procedure. Other waste samples, which were found to be nonmiscible in the acetic acid solution, were tested to determine the effect of chloroform on miscibility. While heavy metal analysis was not done, the miscibility was improved in every case. It should be noted that the chloroform layer can be readily used after leaching is completed to identify the presence of halogenated hydrocarbons and other organics in the waste.

The focus of this project was the identification of nonpoint sources of pollution in the Western Lake Superior region. The area 's predominant soils are red clays interspersed with sands and silts and are easily erodable. Major nonpoint sources of pollution are lakeshores, streambanks, and other slopes. The Red Clay project was a cooperative Federal-local research and demonstration project established to seek practical solutions to the red clay erosion and resulting water quality problems. The study area was divided into five geographical subdivisions representative of conditions in the entire watershed. Studies were undertaken of the condition and behavior of soils within the red clay area in order to utilize available sampling and testing techniques and opportunities to determine areas in which massive slope failure normally occurs. Researchers found that the use of vegetation was significant in erosion control. Red clay turbidity and sedimentation does not add to nutrient loads or oxygen levels in Lake Superior. Possible land management practices are presented. Monitoring of water quality and erosion were conducted at 13 stations, as well as monitoring of rainfall and temperature. Recommendations included keeping a common focus in multiple agency programs, providing cost sharing in nonpoint source pollution management efforts, identification of critical areas through preparation of conservation plans, using a voluntary compliance approach wherever possible, minimizing stream channel deepening, and using streambank vegetative cover wherever possible. A framework is presented for local management agency implementation of project recommendations.

Two competing membrane types are the asymmetric cellulose acetate membrane, the first type developed and used today in most existing reverse osmosis plants; and the composite membrane which has become available in the early 1970s. The composite membrane has superior salt rejection capabilities, but is less able to withstand residual chlorine. The new research direction is in finding a chlorine-resistant composite membrane. The Yuma plant will remove about 90% of the salt from brackish water, and the desalted effluent will be blended with untreated drainage water and discharged into the Colorado River. The Jedda plant, the world 's largest membrane plant, became operational in 1978 and passed acceptance in 1979.

The 208 programs may provide the states with the means to involve the public in planning and determining practical solutions to ground water pollution problems. Needs and obstacles in establishing a 208 program for groundwater planning in Illinois are discussed. The present approach of remedial action for major cases of pollution provides a reasonable degree of protection in terms of control, but there is not a high degree of planning for the management of future ground water quality and quantity in Illinois. The 208 approach addresses three new requirements for plans prepared with Federal funding: (1) plans must have continual public involvement, (2) alternatives must include the definition of mechanisms for implementation, and (3) plans must be updated annually to reflect the results of each year 's progress. Planning programs under 208 are usually regional in scope rather than site-specific. The preparation of a ' 5-Year Strategy ' for each State under the Water Quality Management Planning programs, public involvement, and the USEPA 's new emphasis on aquifer protection as a priority issue will provide the mechanism for funding ground water planning under 208 programs.

The Act was amended in November 1977 to prohibit the dumping of harmful sewage sludge in the ocean after December 31, 1981. Scientific investigations, mainly by NOAA, have documented several adverse environmental impacts at the sludge and dredged material sites. These impacts include elevated concentration of heavy metals, organic matter, and bacterial in the water and bottom sediments with attendant threat of bioaccumulation in the food chain; reduced catches of bony fish in high-carbon sediment areas; FDA closure of extensive areas to shellfishing; enrichment resulting in increased phytoplankton productivity, the occurence of finrot, exoskeleton erosion, and gill clogging in certain marine life; and sediments in the vicinity of the dump sites devoid of normal benthic biological communities. The Congressional mandate has spurred sewage sludge generators to develop and implement alternate disposal methods. All options available have associated environmental risks since metropolitan area sludges contain pathogens, toxic metals, and persistent synthetic organic materials. No matter what method is chosen--landfill, incineration, pyrolysis, composting or recycling, some environmental impact will result.

Prevailing winds and currents carried the oil in a northeasterly direction, causing pollution of the coastal embayments and beach areas in the States of Sao Paulo and Rio de Janerio. In an attempt to protect recreational and other public use areas, particularly the popular beaches of Ubatuba, undiluted dispersants were applied to remove oil accumulations from the shoreline. This response action while it cosmetically removed oil from the surface of the beaches, caused the oil to penetrate more deeply into the underlying sand, thus compounding the pollution and aesthetic problems attributable to the spill incident. Preliminary follow-up studies, conducted seven months after the incident, verified the persistence of the detergent-treated oil in the beach sand.

Eventually, they will play a role in the sole source aquifer designation and management process, and the siting and regulation of pits, ponds, lagoons, sanitary landfills and waste treatment facilities. Examples of successful 208 planning agencies are: Nassau-Suffolk Regional Planning Board (NY); Old Colony Planning Council (MA); and Ventura County Regional Sanitation District (CA). These agencies have used funds to identify problems such as salt-water intrusion and contamination from storm runoff. Through ground water studies, each assessed the extent of the problems and used their analysis to produce protection and control recommendations. Integration of 208 with other Clean Water Act programs as well as with programs established under the Safe Drinking Water Act and the Resource Conservation and Recovery Act are now being explored as a means of increasing water quality management efficiency and capability.

A series of unit operations which could be combined in different ways comprised equalization, lime coagulation, sedimentation, ammonia stripping, activated-sludge treatment, carbon adsorption, and chlorination. The most effective sequence included equalization, lime coagulation and clarification, ammonia stripping, activated-sludge process and final chlorination. This sequence was capable of meeting the consent conditions for discharge to the Delaware river, although limits for BOD and lead were occasionally exceeded, and satisfactory ammonia removal was achieved only following the provision of two aerated lagoons. Phosphorus deficiency in the activated-sludge plant was corrected by the controlled addition of phosphoric acid at the inlet to the aeration tank. JF - Municipal Solid Waste: Land Disposal.

The concentration profile of leachate production over a period of several years is described and the essential parameters for the construction of a mathematical model for predicting concentration and amounts of leachate generated as a function of time are considered. Comparisons between predicted and measured results are presented based on the use of two models expressing both the total solids concentration and the weighted mean COD as a function of cumulative leachate volume. The basic requirements of a practical model which takes into account the site conditions and a gradual filling operation are presented as the basis for a model specification.

Total petroleum hydrocarbon concentrations were determined gravimetrically in stormwater emanating from a northern Philadelphian storm sewer. Comparison of hydrocarbon and sulfur fingerprints of the aromatic fractions of environmental samples to reference oils indicated that crankcase oil was the most likely source of aromatics in stormwater runoff. A weathering study on used crankcase oil showed a loss of diaromatics accounting for their absence in the environmental samples. A method of transport by which land-based oil enters the aquatic environment and receiving water sediments was proposed. Dibenzothiophene was identified in the environmental samples by retention time and mass spectrometry. Concentrations of dibenzothiophene in stormwater runoff ranged from 44.2 to 62.3 ng/L.

AN - 75043548; 400897 AB - Activity measurements are expected to have widespread use in toxicity testing. The multifaceted nature of motor activity will directly influence the selection of a measurement technique since the relative contribution of various motor acts to any particular measurement will depend upon the detection method. Because of the apparatus-dependent nature of motor activity measurements, it is recommended that consideration be given to how accurately the various devices measure locomotor activity. In the present paper, two types of body movement will be considered as locomotor activity: ambulation (horizontally directed movement) and rearing (vertically directed movement). Discussion focuses on the various methods currently used to record motor activity, the various components of motor activity which are likely to be recorded, and the advantages and disadvantages of these techniques for the measurement of locomotor activity. Finally, consideration is given to studies which have compared treatment effects on motor activity derived from two or more measurement techniques.

Age of fish had relatively little effect upon the results. The most intense LAN color production was in epithelial cells of midgut, pyloric ceca, hindgut, and in some segments of kidney tubules. Lower levels of LAN were evident in liver cells of Kupffer, and still lower or slight levels of LAN activity were found in blood cells, muscle, nerve, connective tissue, gonad, and pancreas. The results indicate that LAN might be useful in assessing histotoxicity to LAN-rich areas of the body.

During a separate exposure of embryos and larvae, 1,368 mu g Zn/liter significantly reduced (P = 0.05) both embryo and 12-week larval survival. An additional partial chronic exposure also resulted in significantly reduced (P = 0.05) egg chorion strength and embryo survival at 1,360 mu g Zn/liter. The maximum acceptable toxicant concentration (MATC) for brook trout exposed to zinc in Lake Superior water (hardness = 45.4 mg/liter as CaCO sub(3); pH = 7.0-7.7) lies between 534 and 1,360 mu g Zn/liter. The 96- hour LC50 (median lethal) concentration for brook trout was 2,000 mu g Zn/liter; thus the application factor (MATC/96-hour LC50) lies between 0.267 and 0.680. Brook trout gill, liver, kidney, and opercular bone tissues accumulated the greatest amounts of zinc. Edible muscle tissue did not accumulate zinc. Zinc loss from gill and liver from first-generation trout transferred to control water for 12 weeks was 55% and 59%, respectively, based on the total micrograms of zinc per whole tissue. Zinc in kidney tissue (based on the total micrograms of zinc per whole tissue) increased 192%, however, during the 12 weeks in control water.

The Environmental Protection Agency (EPA) was aurorized to provide technical and financial assistance to aid in attaining these goals. However, the large number of programs and lack of coordination greatly showed the implementation process at the local level. Emphasis is now being placed on State/EPA agreements to facilitate the implementation of the various programs and funds. The Clean Water Act Amendments of 1977 are expected to encourage more small town use of construction grants for waste treatment systems by simplifying government requirements of the states and local areas. Beginning in 1980, State/EPA agreements will be expanded and will involve all of the programs under the Resource Conservation and Recovery Act and the Safe Drinking Water Act. It is hoped that States will begin to develop overall environmental planning and management programs instead of making small individual efforts. Program coordination efforts are suggested for: (1) data collection for population and wasteload projections for all programs, (2) monitoring efforts for all programs, (3) water quality assessments for both surface and ground-water resources, (4) effective facility planning, and (5) wasteload allocations.

About 24% of the projects has a high degree of coordination between project sponsor and State water quality management programs, 43% had a low degree of coordination, and 33% had almost no coordination. On the Federal level, high coordination indicating active participation by another Federal agency was found in 17% of the projects, low coordination in 20%, and no coordination in the rest of the projects. These results indicate that: (1) a clear set of objectives and priorities needs to be developed at the State level, (2) more emphasis is needed on preventative and curative restoration measures, (3) a comprehensive water quality management program is needed, and (4) all applicable programs in specific project areas need to be coordinated. New State/EPA agreements are expected to help with coordination. Also expected to help is section 208 of the Clean Water Act which can be used to initiate and manage projects. The Model Implementation Projects (MIP's), a series of projects with similar objectives to the clean lakes programs have resulted from 208 planning. Project examples are Broadway Lake in South Carolina and Lake Herman in South Dakota. Continued program integration is needed to provide more effective water quality management.

The lake restoration program requires states to classify and identify water quality conditions in their publicly owned freshwater lakes and include procedures, processes, and methods to control pollution to eutrophic lakes and techniques to restore them. However, lake restoration is applicable to all trophic levels and all improvement aspects of the ecology of these waters. A 50% federal matching fund is available for restoration activities. Since the program began there has been little input by fishery scientists into the plans, processes, and management schemes for lake restoration projects during and after their inception. Some parts of the lake restoration program where fishery biologists could play a major role are: (1) installation of spawning beds where they do not exist or are inadequate to support a viable fishery; (2) installation of hypolimnetic aerators to maintain DO concentrations; (3) control of bottom rooting fish such as carp as an upstream watershed erosion control technique; (4) elimination of vital spawning areas by dredging a shallow area; (5) increasing spawning grounds for game fish by constructing an access to a marshy area; (6) removal of low head unused dams on tributary streams to allow upstream travel of spawning fish.

From these standards a state can then determine the water quality criteria necessary to meet the standards. Once the standards and criteria have been determined, appropriate steps must be taken to protect the body of water for its selected use. Possible steps include preventing runoff from the watershed, control of wastes from industry and agriculture, and control of sewage treatment plant wastes. The Environmental Protection Agency 's clean lakes program is designed to help states with setting water quality standards, determining the needed criteria, and the necessary steps. Also, the program provides funding to help states carry out the necessary steps such as to control of nonpoint source pollution in watersheds and the correction of in-lake pollution problems. Other programs , agencies, and services that can be integrated with the clean lakes program include: the 208 water quality management program; the National Pollutant Discharge Elimination System (NPDES) permits program; the 201 construction grants program; the Agriculture Soil and Conservation Services; the Community Development Block Grant program; the Appalachian Commission; the Land and Water Conservation Fund; the Agriculture Stabilization and Conservation Service; the Energy, Environment, and Natural Resources Program; and the Land and Water Conservation Fund.

EPA prepared an environmental impact statement for the project in 1975. The original proposed waste water treatment facility was a two-stage activated sludge plant, with tertiary sand filters, phosphorus removal, and chlorination. However, due to the high natural quality of the Olentangy Rivers, EPA concluded that the residual chlorine concentrations that would be released into the river would be extremely hazardous to the river 's quality. The Olentangy River is a State Scenic River with good dissolved oxygen levels, a high diversity of aquatic insects, a variety of mollusks including four state endangered species, a wide biological diversity, and is one of the few remaining natural stream segments in central Ohio. Alternative disinfection agents considered were ozone, sulfur dioxide effluent dechlorination, bromine chlorine, and ultraviolet light. Ozone was selected because it is produced on site and does not have to be stored, it has been used for several years in drinking water with no observed toxic effects, and it does not increase instream levels of dissolved solids. While ozonation was more costly than chlorination in terms of monetary investment, it was less costly in terms of social and ecological factors. Text of a brief discussion on the paper is included.

The Federal government became involved in 1972 with the enactment of the Federal Water Pollution Control Act. In 1975, Federal financial support became available to states for their water quality programs. Since then $36.3 million have been appropriated for this purpose. Actual project costs are approximately twice this amount since Federal support represents only about 50% of the total funding. Federal funding through the Environmental Protection Agency 's clean lakes program has been used to support water quality restoration projects in 73 lakes in 23 states. The program is primarily directed toward the control of nonpoint pollutants and the implementation of methods to hasten lake recovery after the control of the pollutants. In 1978 EPA made funds available to states to inventory the extent and nature of eutrophication in significant lakes and to support feasibility studies for those methods most suited to restore lake water quality. EPA is currently developing regulations for the future management of the clean lakes program. Increased EPA/State agreements should make the program more effective. Future program focus will deal strongly with the impacts of nonpoint source pollutants and on the methods, management planning, and implementation of best management practices to correct the pollution sources.

Lake inventories for the area include results from 34,000 lakes or 36% of the national lake total for the 48 contiguous states. Lake surveys and classifications are expected to increase in frequency and intensity as closer relationships develop between performing agencies. Region V currently has 18 Environmental Protection Agency grants totaling $17.3 million. Of the projects , 71% are for watershed controls for urban or agricultural nonpoint source drainage. Program focus is predominantly on urban lakes, especially in Minnesota for the Twin Cities area. Dredging is the predominant technique used for correcting effects of past abusive land use practices. Although none of the 18 projects has yet produced sufficient data to measure its success, seven projects have shown some favorable results. Most notable are the White Clay and Mirror Lake projects both of which have produced beneficial results. The region is supplying additional manpower to provide pre-application assistance and program administration assistance. A handbook is being developed to assist communities in assessing the degree of lake pollution from septic tanks.

The objectives of the Ambient Water Quality Monitoring Network (AWQMN) are: 1) to establish baselines of water quality; 2) to characterize and define trends in the physical, chemical, and biological condition of the state 's surface waters; 3) to provide for a continuing assessment of water pollution control programs; 4) to identify and quantify new or existing water quality problems or problem areas; and 5) to act as a trigger mechanism for intensive surveys or other appropriate actions. Because objectives of the AWQMN were defined before it was designed, siting factors could be selected and priorities determined to best achieve those objectives. Ten site selection criteria were established, including at least one sampling site in each segment, networks of about 220 stations, availability of flow data, and maintenance of current data files. Sites with similar characteristics should be identified and grouped for analysis purposes. Each station can, therefore, be considered in one, two or more of seven sub-networks of the total AWQMN plan. The frequencies of sample collection are guided by the objectives of the AWQMN. Types of sampling include grab sampling, composite monitoring and automated continuous monitoring. The Illinois Environmental Protection Agency and the U.S. Geological Survey have a cooperative program under which USGS monitors a portion of the network and provides flow data at most network stations as well as extensive manpower training, equipment, data processing, and program quality control. Informal agreements with other agencies have permitted reduction in monitoring efforts required by the Illinois EPA.

To provide that frame of reference, the 50 States were contacted and representatives were questioned as to the nature and extent of their existing groundwater programs. The survey of States produced a wealth of information relative to the structure of various State programs, and this information was presented graphically in the neutral presentation. The subject of multiple agency involvement was addressed. In addition to looking at the structure of State programs, information was collected regarding the nature of existing State statutes and regulations. Tabulation and interpretation of this information were provided to illustrate how the institutions are providing for the protection of our groundwater resources. In addition to evaluating the various types of statutes, existing enforcement mechanisms were researched and presented for review. Graphic presentations of the national data base were used, and again several States ' procedures were reviewed in detail. The topic of groundwater quality standards was specifically addressed during interviews in order to note the extent of this developing regulatory technique. The presentation provided a national look at existing groundwater programs with in-depth analysis of certain State programs. The variations in State programs were highlighted and an attempt was made to estimate resources currently dedicated to groundwater protection at the State level.

The role of EPA in agricultural research was discussed in terms of both the nature and extent of activities, within the context of cooperation with the agribusiness community. Reliance on typical soil and water conservation measures as best management practices for maintenance of water quality was viewed from the perspective of present technical knowledge and system assessment capabilities. Additional studies necessary to confirm the link between water quality and best management practices were suggested. It was suggested that improved monitoring techniques, instream water quality surveys, and a better understanding of sediment/pollutant adsorption and desorption mechanisms are required in the near future to sharpen the guidelines for establishing agricultural nonpoint source management systems. Needed area-wide pollution problem assessment methodologies, BMP field evaluation, mathematical modeling of transport phenomena, and predictive techniques for BMP system comparisons were outlined. The projected extent of EPA/ORD involvement in these future activities was examined in light of potential resource availability and was compared with similar activities in other Federal, State, and local agencies and institutions.

Federal regulations, however, must provide flexibility to States and industry to find the least costly means of meeting national environmental goals. A growing body of literature clearly documents cases of underground drinking water source contamination, sometimes severe, from a large variety of conditions and practices. Existing studies also indicate that this problem is pervasive: aquifers have been adversely affected in every region of the country. A federal groundwater protection program which (1) reflects consideration of total long-range natural resource protection and environmental quality benefits, (2) regulates in a manner so that the benefits to the environment generally exceed the regulatory costs, and (3) encourages more efficient ways of meeting environmental goals in the least costly manner can and must be developed by the Environmental Protection Agency. Without an effective Federal groundwater protection program, the underground contamination problem will likely worsen. (Sims-ISWS) JF - Ground Water Vol. 17, No. 1, p 80-82, January-February 1979.

The cost distribution should be equitable and stable (in the sense that incentives for groups to break away and form separate systems are minimized). Concepts of n-person cooperative game theory are utilized to develop quantitative measures of equity and stability. These measures are incorporated into linear programming models that allow explicit equity-stability tradeoffs to be made in distributing the costs of the least-cost regional service plan. Examples that demonstrate the use of the methods are provided.

In building the new program, we should use the host of lessons learned in the experience of related environmental programs. This is necessary so that the new program will be realistic at the outset and congruent with the integrated planning and management of the ground- and surface-water resources of the nation. The keystone of program development, implementation, and evaluation is and will continue to be water quality standards. To the extent that the goal ' Safe Drinking Water for Americans ' has already been established, the point-of-use regulations should serve as water quality objectives, thus facilitating groundwater program formulation and evaluation. The major regulatory thrust of the program, the water quality standards, must be technology-based site selection, construction and operational standards, with only limited monitoring in a conventional water supply and water pollution control context.

The Environmental Protection Agency is about to launch a number of programs designed to protect what is , in many cases, a virtually nonrenewable resource. Separate regulatory activities mandated under the Safe Drinking Water Act , the Resource Conservation and Recovery Act, and the Clean Water Act must be coordinated carefully if they are to be effective. The current implementation efforts within the agency are being framed in view of our major principles which will be the focus of public comment in the months ahead. These principles are: (1) The administration of the related programs will be a cooperative effort involving Federal, State and local governments, all of which must participate in formulating the program if it is to be effective. (2) The focus of the programs will be on the prevention of contamination rather than on its treatment at the point of withdrawal. (3) The applicable standards will be based primarily on technology rather than ambient groundwater quality considerations since the effects of discharges upon ambient quality are complex, difficult to predict, and of long duration. (4) There is a need to balance environmental protection, energy development, and continued economic prosperity objectives so that the resulting programs fully protect public health while being realistically implementable. All of us--government, industry and citizens, through acts of commission or omission--have contributed to the potential problem. We must work together if we are to get on with the important task of protecting the quality of the Nation 's groundwater resources.

Characterization of the relevant relationships between physical exposure and the effects of noise on people has been fostered through the use of a wide variety of sound descriptors. Many of these descriptors were historically derived from sets of contours representing judgments of loudness, noisiness, or acceptability of sound. Many of these evolved merely as variations of one another. The apparent differences between the many assorted descriptors are simply due to differences in treatment of the many acoustic and non-acoustic parameters which are known or thought to influence human response to sound. The purpose of this tutorial paper is to review some of the more common sound descriptors used to portray our acoustic environment, as well as their derivations, formulation, applicability, and limitations.

Since the cost of conventional sewerage rises prohibitively as the population density decreases, and the collection costs may represent 75 per cent of the total sewage charges, a decentralized form of treatment becomes an economic necessity. Either soil-dependent or non-soil dependent systems may be adopted, according to local climate and conditions. Septic tank installations required planned maintenance for effective operation, and the effluent from a large number of such systems may require too large an area of land; however small-diameter pressure sewers connected to a sewage lagoon or other treatment facility may provide an economic alternative to sub-surface disposal of septic tank effluents from adjoining properties.

Turbidity has been kept to less than 01 Ntu and detecting capcity for amphibole fibres is now 0030 x 10 6 fibres per litre. This was achieved in treating Lake Superior water whose fibre counts rose to 1 billion fibres per litre during storm conditions. The success of the filtration plant has led to vastly improved water quality in reservoirs and distribution systems. Aluminium sulphate solution is used as primary coagulant, sodium hydroxide for pH control and non-ionic polymers for amphibole fibre removal. The use of fluoride has made possible a lower alum dose.

No.2026) . After three years total phosphorus and solube reactive phosphorus concentrations had declined from 50 and 21 ug per litre to 30 and 45 ug per litre. A form of the phosphorus residence time model, incorporating the feedback of phosphorus from the sediment, accurately predicted the phosphorus patterns over the first three years. Inflow from rivers, atmospheric precipitation and waste water, and outflow via evaporation and ground water showed corresponding seasonal variations, reflected in phosphorus values, with a major deviation from predicted total phosphorus levels in July and August. There was a significant increase in algal biomass during these months.

The minnows are analysed, 5 at a time, after 2, 4, 8, 16, 24 and 32 hours. A first-order uptake model is used and the steady-state bioconcentration factor is calculated from the 32-day exposure. A structure-activity correlation between bioconcentration factor and the n-octanol/water partition coefficient permits estimation of factor to within 60 per cent, before analysis. Bioconcentration factors derived from tests of mixtures of chemicals are shown to be the same as those derived from tests with individual chemicals.

The release of effluent from septic tanks is considered as presenting a possible threat to the purity of groundwater supplies, while the injection of oxygenated water into an aquifer in the area surrounding a supply well has been shown to stimulate certain desirable bacteria, thus improving the output and quality of water produced. Studies of the rate of migration of viruses and bacteria in the soil and porous media have also been reported. 49 ref.

Some of the changes may be viewed as desirable, others undesirable, according to their nature and motivation, although all may upset the original ecological balance between different species . The contrasting values assigned to community function by different groups of individuals are discussed, including empirical relations between value and size of certain aquatic communities. Other parameter such as primary production, photosynthesis and total biomass may be important from an ecological viewpoint. The problem of interpreting laboratory data against such a complex background of values and ecological changes is broadly discussed and certain discrepancies between laboratory data and subsequent field testing are briefly considered.

Mortalities occurred at all concentrations tested; at concentrations of 11 g per litre and above over half died during the 42-day experiment. Ten per cent died at the lowest concentration of 5 g per litre. Growth was inhibited at all concentrations. Copper appears to cause detachment of the scallop prior to death, some did adjust to the copper and re-attach themselves. Scallops are shown to be very sensitive to copper.

From the available information they conclude that, because of marketing practices and the types of crops grown on sludge-amended soil, health effects from cadmium in sludge applied to agricultural land are not likely to be a problem. In addition, there is so far no epidemiological evidence to suggest that actual human illness has been caused by the use of sludge on land, where the sludge has been properly treated and applied. Dairy cows should not be permitted to ingest sewage sludge, since many organic compounds, which may adhere to plants, tend to accumulate in lipid-rich tissues and fluids such as milk.

The results of monitoring of ground-water for molybdenum, selenium and radioactive isotopes are reported, together with several case histories of groundwater pollution at uranium mill sites and tailings piles in 8 western states. The results demonstrate the influence of hydrogeological conditions in determining the pattern of migration and also the deficiencies in the present state of knowledge concerning long-term behaviour at such disposal sites. In the light of the proven inability to prevent the spread of pollution of ground-water at several sites, more stringent monitoring and control procedures have had to be introduced.

Mine subsidence is projected to increase by 34 and 115 per cent respectively for 1985 and 2000 . No increases are projected for acid mine drainage from surface mines or waste, since present legislation should control the problem. The causes, effects, and control of acid mine drainage are outlined. Treatment can be by reverse osmosis or ion exchange. Formation of acid mine water can be controlled by preventing its influx and aquifer control. Subsidence is also discussed in detail with reference to cause and effects, and control.

Concentrates were prepared from all samples by reverse osmosis, using either a nylon or cellulose acetate membrane, the organic fraction being isolated by extraction of the concentrate using pentane and methylene chloride under both neutral and acidic condtions. Evidence of mutagenicity was obtained in a few cases, and certain compounds, including a weedkiller and some plasticizers, were detected in the concentrates among a range of 54 compounds regarded as of special interest.

Although both benefits and costs are necessarily estimates, the model lends perspective to and indicates trends for estimating the cost of a water quality improvement as opposed to its health benefits.

Loughlin AN - 19205790; 8003137 AB - This comment takes exception to Loughlin 's (1977) (See W78-02186) examination of three schemes for allocating costs of multipurpose projects to individual purposes with respect to a set of equity and efficiency criteria. Loughlin concluded that only the separable costs-remaining benefits (SCRB) method will satisfy the equity criterion. Two objections are raised: (1) Certain of the efficiency criteria should not be used for evaluating cost allocation methods; the criteria in question are actually project evaluation criteria and should be applied to the project before any cost allocation is made. (2) Loughlin 's adjusted SCRB method actually gives less-equitable results than the original SCRB formula for projects where the justifiable costs with a purpose deleted are given by the alternative cost of providing all other purposes. A revised set of cost allocation criteria separate from the economic evaluation criteria and thus in keeping with the equity principles used by Loughlin would be: (1) The sum of total costs allocated to each purpose should equal total project cost. (2) The total costs allocated to each purpose should not exceed the cost of a single purpose alternative providing equivalent benefits. (3) Savings allocated to each purpose should be in the same proportion as savings realized by including each purpose in the project. The remedy to the problem of the SCRB formula not satisfying the equity criterion is simply to redefine the separable cost of a purpose as the total project cost minus the justifiable cost with this purpose deleted.

However, even in the absence of such charges, municipal treatment plants have been constructed for many years, an indication that to a significant degree, states and communities have internalized the pollution costs of waste water discharges. The motivation for such investments varies widely, however, since before secondary treatment became a Federal requirement, the percentage of the sewered population in a state receiving such treatment ranged from 9 in New Hampshire to 100 in New Mexico. Using regression techniques, this analysis explains 40-45% of the variation in treatment levels among states in 1968 in terms of factors such as the availability of assimilative capacity relative to waste loads and the recency of urban development. The results of state and local programs appear to have been rational, broadly speaking, more extensive treatment being applied where pollution impacts would be greater. Some of the economic implications of the construction grant program, which provides an added incentive for treatment plant investment , are discussed in the light of these results.

The zinc concentrations utilized were 30 to 112 mu g/liter during the adult-to-smolt exposure period, and an additional 242 mu g/liter concentration was used for the embryo-to-smolt exposure period. These zinc concentrations produced no adverse effects on survival, fertility, fecundity, growth, or on the subsequent survival of smolts transferred to seawater. Exposure to 242 mu g/liter produced sufficient acclimation to markedly decrease acute mortality at zinc levels lethal to unacclimated sockeye salmon juveniles. The 112- and 242- mu g/liter concentrations were 0.15 and 0.32, respectively, of the 749- mu g/liter, 96-h LC50 for the 8-mo-old sockeye salmon. An application factor relating 96-h LC50 and 'safe' concentrations of zinc to anadromous sockeye salmon in soft water appears to be >0.15 and at least 15 times larger than the often recommended 0.01 application factor for zinc based on studies with other species.

Newly hatched alevins were much more tolerant to cadmium and, to a lesser extent, to zinc than were later juvenile forms. However, the later progression from swim-up alevin, through parr, to smolt was accompanied by a slight increase in metal tolerance. The 96-h LC50 values for all four life stages ranged from 1.0 to >27 mu g Cd/liter, 17 to 38 mu g Cu/liter, and 93 to 815 mu g Zn/liter. Steelhead were consistently more sensitive to these metals than were chinook salmon. When a sensitive life stage for acute toxicity tests with metals is sought, the more resistant newly hatched alevins should be avoided. Although tolerance may increase with age, all later juvenile life stages are more sensitive and should give similar results.

In addition, Chesapeake Bay is threatened. EPA 's Kepone Mitigation Feasibility Project was undertaken to address the threat posed by Kepone contamination and to recommend possible cleanup action. The project involves: (1) assessment of the biological and ecological impact of Kepone through literature search, laboratory and field studies; (2) assessment of the potential sources of continuing contamination by inflows into the James River; (3) sampling and evaluation of the contamination in the James River; (4) modeling the movement of contaminants; and (5) evaluation of potential conventional and nonconventional methods for mitigating the problem. Preliminary results indicate that continuing inflows of contamination into the James River exist, and that there is no evidence of any degradation in the pesticide or indication that natural causes will substantially alleviate the problem in the foreseeable future. While some mitigation methods now look promising, their cost-effectiveness must be evaluated.

A second purpose of the Act is to gather new health effects information through the testing of toxic chemicals. A third objective is to control the chemical industry in the prevention of pollution. The law provides that research may be performed in any area necessary to support the purposes of the Act. This includes health effects research, epidemiological research, and discovery monitoring. In terms of enforcement, the EPA regional offices have substantial authority for inspection both within the normal court procedures and unexpectedly by entering a plant without a warrant. The law also bans the production of PCBs.

Results indicated that chronic exposures of C. virginica to chlorine-produced-oxidant (CPO) products can produce considerable mortality at high concentrations and severe sublethal effects at lower levels. Toxicity is related to seasonal changes in measured CPO concentrations, temperature and the physiological condition of the oyster. Sublethal effects appeared to be related to reductions in feeding and increased avoidance of CPO. This resulted in reduced tissue production causing severe reductions in the size of gonadal tissues as well as increased dependence upon glycogen reserves during exposures to CPO.

The concentration of test compounds which inhibited or stimulated cell division were determined and are presented in tables. All four species of algae responded to the compounds in a like manner. Monochloramine was the most inhibitory compound tested. Halogenated phenols gave varied responses. At the concentrations tested, p-chlorophenol and 2,4,6-tribromoanisole yielded no toxic effects. Five compounds were growth inhibitory (p-bromophenol<2,4,6-tribromoanisole<2,4,6-trichlorophenol < pentachlorophenol < pentabromophenol). Pentachlorophenol and pentabromophenol were highly inhibitory. The halogenated hydrocarbons were all stimulatory to the algae.

Starting on 26 April during a simulated spring-to-summer rise in water temperature, some were continued at the original oxygen concentrations while others were subjected to mean diel fluctuations ranging from 0.8 to 1.9 mg O sub(2)/liter above and below the original concentrations. Controls were maintained at concentrations near air saturation. No spawning occurred at the lowest fluctuating treatment of 1.8 to 4.1 mg/liter.

Quality problems concerning the international waters of the Great Lakes and the application of modeling techniques to Saginaw Bay are considered. Problems are categorized into a series of time and space scales. The series ranges from the short-term transport of some hazardous material within a very localized area to the long-term effects of control or limitation of nutrients or toxic materials within the drainage basins on the ecosystem of individual lakes or of the whole system of lakes. This paper attempts to integrate these different approaches. Applied are transport models and algal growth modeling concepts to Saginaw Bay to describe its prevailing conditions. The simulation model developed is based on available data on the bay, and the modeling concepts will be verified by using an extensive set of field data collected from a sampling design aimed specifically at this modeling program. This modeling system will be used to evaluate the response of the system to a range of management alternatives for enhancing water quality.

A realistic estimate of needs for AWT facilities is $1.5-2.0 billion, covering the cost of plants for total nitrogen removal or achievement of BOD limitations of less than 10 mg/l. A review of 6500 projects shows only 330 will require treatment to achieve these levels. In some cases AWT is mandated by state requirements, but costs of compliance may exceed benefits. The Vertex study, commissioned by EPA, indicated many AWT projects carried out with inadequate planning and justification resulted in excessive expenditures and insufficient compensating benefits. Improved monitoring is needed at the state level. Over 65% of the grants have gone to communities of 10,000 or less, many of which are experiencing financial problems. In 40% of the communities, operation and maintenance plus debt retirement for new facilities will cost over $100/household/year. An expensive treatment system is one in which such costs are 1.5-2.5% of local median income, the case in 10-20% of these communities. Several provisions of the 1977 amendments to the Water Pollution Control Act address these problems, providing more assistance, allowing more flexibility, and removing some of the paperwork. Five of the provisions are discussed. (Lynch-Wisconsin) JF - Pollution Engineering Vol. 10, No. 9, p 40-43, September 1978.

II. A methodologic study of linear regression analysis of asthma panel data. AN - 74437835; 318499 AB - Panel studies relating illness, such as asthma attacks, cardiopulmonary symptoms, and acute respiratory symptoms, to daily air pollution and weather are important in environmental epidemiology. A study of the practical robustness of multiple linear regression procedures, which have been the preferred statistical models in analyses, is presented. The study is based on data from three asthma panels in Chattanooga, Tennessee, collected in 1972-1973. Linear regression models, commonly used, which incorporate only minimum temperature and an air pollutant were found to be potentially misleading; such models are highly sensitive to reporting trends in the data and do not correct adequately for weather variables. Temporal and spatial control strategies were employed and proved to be useful in detecting problems in the data due to undiscovered intervening variables. True day-to-day relationships estimated by a pair-day analysis were frequently inconsistent with "daily" effects estimated by the usual regression models and suggested that, in fact, the asthma panel data contained no useful information concerning day-to-day relationships.

The method is developed with respect to the specific problem of minimizing the costs of basin-wide thermal and organic pollution control to meet water quality standards. It views the problem in partitioned form where a master problem is sued to find cooling levels for thermal polluters while subproblems determine optimal organic pollutant reductions for fixed cooling levels. A gradient-based search procedure is used to solve the master problem. Computational results for several river systems are presented. Application of the method to other water quality management models is suggested. The application of this approach to complex water quality management models should improve computational efficiency and make the use of such models more attractive to basin planners.

The model explicitly considers the interaction between facility location and capacity expansion decisions on total system cost. Cost functions for treatment facilities and interceptors and growth patterns for future wastewater flows may be of any form. The model is solved with a three-phase heuristic procedure utilizing dynamic programming. In comparison with a mixed integer programming model of a large-scale problem, the procedure demonstrates significant advantages in computational time, accuracy, and user requirements. The model is applied to facilities planning in a 208 study area of Massachusetts to demonstrate how the economic impacts of alternative management objectives and demographic projections can be assessed.

A diverse, typical hard-water flora was found. Submergent Ceratophyllum demersum was the most frequently occurring species, while the greatest portion of the total biomass of Pool 8 consisted of the emergent Sagittaria latifolia. The average summer crop of 181.70 g/sq m for the littoral zone was comparable to that for hard water lakes in Wisconsin. Two areas, typical of the mid and lower sections of Pool 8, were sampled six times between May 28 and August 25, 1976. Maximum productivity rates were coincident with the flowering and fruiting of Nelumbo pentapetala, Sagittaria latifolia and Vallisneria americana. S. latifolia was the most productive.

However, the groundwater contamination could be easily corrected at both sites by storing the effluent during the winter months and applying it so that nitrogen inputs are in balance with nitrogen uptake by crop plants. With such management soils at both sites potentially can remove contaminants from wastewates for many more years. Chemical analyses were carried out March 1975 at Bakersfield and June 1976 at Lubbock. In both localities about 16 mg of effluent are applied throughout the year on row and forage croplands. In general, crop production has been increased by use of the sewage effluent for irrigation, compared with alternate water sources and commercial fertilizer used on neighboring farms. At Bakersfield sewage is aerated for six hours prior to solids removal in clarifiers, then surface irrigated. At Lubbock all land application is conducted by one local farmer, who recently installed center-pivot sprinklers.

Although several problems have resulted in a slowdown in permit processing and enforcement, Illinois has the necessary regulatory mechanisms to satisfactorily administer the state 's water pollution control program.

The vapor condenses into ice particles, which severely restrict visibility during extremely difficult driving conditions in subarctic areas, such as Alaska. The three major sources of ice fog are automotive and truck exhausts; open water surfaces, such as cooling ponds; and exhaust gases from heating and electrical powerplants. Research was conducted during the 1974-75 and 1975-76 winters, to determine and evaluate methods of reducing automotive generated ice fog. The major technique evaluated was removing the water vapor as a liquid condensate using cooler-condensers. These devices are heat exchangers in which the exhaust gas is cooled by cold ambient air or coolant from the automobile radiator. It was found that when using the cooler-condensers only, much of the condensed water formed a mist; therefore, use of coalescers was necessary to transform the mist into water. As on-the-road performance of a cooler-condenser equipped vehicle revealed that 81% of the overall water vapor was condensed at an ambient temperature of -16F. Estimations are that 50% of the ground level ice fog is generated by automotive sources, and that if ice fog control devices yielding an 80% reduction were used, vehicle ice fog emissions would be reduced approximately 40%.

The tertiary plant used either two-stage high lime or single-stage low lime followed by dual-media filtration and granular activated carbon adsorption. The high lime process significantly reduced residuals of BOD, TSS, and phosphorus in the secondary effluent using an average dosage of 257 mg/liter CaO and 18 mg/liter FeCl3. The low lime process produced similar removal of residuals using an average does of 113 mg/liter CaO and 25 mg/liter FeCl3. Tertiary treatment did not affect total nitrogen residuals. Regeneration of the tree columns under less than optimum conditions resulted in carbon losses estimated at 8 to 10%. The tertiary treatment demonstration plant had operating costs which ranged from 29 to 36 cents per 1000 gal. Since these costs were obtained during start-up, they are probably unusually high. Efforts to select, train, and maintain a highly competent staff are recommended for optimum plant operation.

The indices published in the literature and surveys of the States and interstate commissions are reviewed to determine: (1) which agencies are using indices, (2) the type of index being used, (3) the purpose of its use, and (4) the attitudes of agency personnel toward indices. One-fifth of the State and interstate agencies (12 out of 60) were classified as users of water indices. Of the 51 state agencies (including DC), 10 states (20%) were classified as index users. The National Sanitation Foundation Index was the most commonly used, by 7 of the 12 index users. The remaining agencies use Harkins ' index or various user-developed indices. A total of 16 additional State and one interstate commission are planning to evaluate indices for possible future application or are developing or evaluating indices at the present time; these were classified as ' potential users'. Six new indices have been developed by water pollution control agencies; their mathematical structures are documented. The main purposes expressed by index users for applying their indices are preparation of the annual reports required by Section 305(b) of P.L. 92-500, public information, and analysis of water quality trends. Most users feel that EPA should have a suggested index available (or a set of indices) for those agencies that wish to use a uniform index structure. There is clear evidence of a trend toward increased utilization of water quality indices. Several recommendations are included for meeting the needs of index users, attaining greater uniformity in water quality data analysis practices, and identifying future research needs.

Of the parameters examined, hematocrit, lactic dehydrogenase, and creatine phosphokinase were found to be the most significant indicators of stress due to repeated sampling. We showed that, under conditions similar to those of this investigation, daily and weekly sampling of approximately 0.2% of the body weight in blood produced decidedly deleterious effects of the test organisms. Starvation was a secondary stressor and is believed to have had an influence on blood characteristics as the study entered its later phases.

Cadmium and zinc did not act additively at sublethal concentrations when combined as mixtures; however, a joint action of the toxicants was indicated. Effects on survival showed that the toxicity of cadmium and zinc mixtures was little if any greater than the toxicity of zinc alone. Mechanisms of zinc toxicity in this test were similar to those in previous chronic tests of individual metals, indicating that the presence of cadmium did not influence the mode of action of zinc. Comparisons between metal residues in fish exposed to each individual metal or to the metal mixtures showed that the uptake of one metal was not influenced by the presence of the other.

Through the establishment of a permit program, the U.S. EPA 's Middle Atlantic Region III has brought the indiscriminate disposal of municipal and industrial wastes under control. The goal is to eliminate ocean disposal of harmful waste by January, 1981 through the development of sound, reasonable and environmentally acceptable land based alternatives. Until that goal is attained, an intensive monitoring program has been established to assess the fate and effects of all pollutants dumped into the Region 's waters.

The Los Angeles Hyperion Treatment Plant discharges 1.2 mgd of sludge through a 7 mile long outfall to a submarine canyon. The 40 acres of land formerly employed by the Los Angeles County Sanitation District for winnows in the composting of sludge are required for plant expansions. The San Francisco Bay area disposes of 55% of its sludge in landfills, 30% in storage lagoons, 10% by incineration , and 5% as soil conditioner. Ocean disposal of sludge in California has been banned by 1980 and real estate costs are becoming prohibitive. An estimated 16,000 acres of farmland would be required for land application of all the sludge produced. Anaerobically digested sludge, dewatered to 20% solids content, can be composted and sold for domestic and commercial landscaping. Sludge must have a 25-40% solids content for efficient combustion; thermal processing can produce polychlorinated biphenyls and vaporized mercury as well as other air pollutants. Improved thermal processing techniques are under investigation. Pyrolysis of sludge generates gases which can be used as a fuel source in plant operations but pilot plant studies have indicated problems with the technique.

The total contributing area of the watershed was 2.70 sq miles, which comprises about 20% of the total city land area. Approximately 70% of the basin has been developed, and consists primarily of middle-class, single-family dwellings, together with the usual scattering of multiple-family units, light industry, shopping markets, and roadside services. Impervious surfaces such as paved streets, driveways, parking lots, and rooftops cover about 19% of the total land surface of the basin. Upper reaches of the watershed remain as grasslands and evergreen forests. The study indicated that runoff contributed gross quantities of sediment to the watershed, and that treatment should focus primarily on solids removal. However, it was cautioned that a substantial portion of the sediment contained in the runoff samples appeared as colloidal particles that will not be removed by simple clarification.

Case histories illustrating sampling errors, errors in bacteriological sampling techniques, and problems with the Maximum Contaminant Level standard, are presented. Two proposals for further changes in microbiological regulations are presented. These simplify the monitoring process by prohibiting the presence of any coliforms in a certain number of samples rather than by setting acceptable levles of coliforms for samples.

This point is demonstrated by a discussion of certain general biological toxicity response mechanisms. For example, water soluble substances are likely to produce a stronger and more widespread effect than non-soluble substances. However, non-soluble materials can travel down a stream as an undiluted mass or slug, killing organisms in its path on contact. In other cases, a non-soluble material may be miscible forming a coating over the surface which asphyxiates or prevents proper feeding of some organisms. Toxic substances may act directly to kill life forms and juvenile stages are usually the most sensitive. Toxic substances may also act indirectly by destroying food sources or by reducing resistance to infection and stress. Recovery of damaged ecosystems is discussed with emphasis on the feasibility and desirability of intervening to aid or speed restoration. Careful analyses of genetic, physiological, and ecological factors are essential to deciding where, when, and how restoration attempts should be made.

Eggs, embryos, and newly hatched fry were not affected at 126.7%, but at about day 16 posthatch when the fish began swimming up deaths occurred rapidly, and at the end of the test post button-up mortality ranged from 99% at 126.7% saturation to 45% at 115.3% saturation. Bubbles in the mouth, gill cavity, and yolk sac caused flotation and severe respiratory difficulties. Rupture of yolk-sac membranes also caused death. No differences were noted in survival between fish exposed from egg to fry, and those exposed only from swim-up to fry stage. In summary, there were differences in susceptibility among steelhead life stages to air-supersaturated water; eggs, embryos, and pre-swim-up larvae were more resistant than swim-up and later fry stages.

The Safe Drinking Water Act, perhaps the law with the greatest impact in this area, is omitted from discussion. The statutes discussed are: (1) the 1972 Federal Water Pollution Control Act Amendments (FWPCA); (2) the Toxic Substances Control Act; (3) the 1976 Resource Conservation and Recovery Act; (4) the 1969 National Environmental Policy Act; and (5) two executive orders on the subject. Control of groundwater quality protection on federal lands and federal facilities is also discussed. The FWPCA requires waste-treatment management plans to include processes necessary to control groundwater quality. States are required to enforce any groundwater provision of any Section 208 agency. The federal Environmental Protection Agency (EPA) is required to issue guidelines for methods to control pollution resulting from the disposal of pollutants in subsurface excavation. The EPA may delegate to the states the power to issue permits controlling the disposal of pollutants into wells. The impact on groundwater protection by the other legislative acts is also discussed in detail. (Quarles-Florida) JF - Water and Sewage Works Vol. 125, No. 4, p 68-70, 1978.

Because the results of the coliform test can be interpreted in different ways, problems are experienced with the test, especially in small systems. Problems with enforcement are also briefly considered. (See also W79-10127) (Small-FRC) JF - Evaluation of the Microbiology Standards for Drinking Water Report EPA-570/9-78-00C. p 211-214, 1978.

The original 1914 standard limited the detection of Bacillus coli to one out of five 10 cc portions of any sample. The 1942 and 1946 Public Health Service Drinking Water Standards required number of samples, standard portions, and standard samples. In 1971 the Interstate Carrier Water Supply Program came under the control of EPA. Carrier water quality had to meet all the limits of sections 3.2 and 3.1 of the 1962 standards. These systemized requirements resulted in improvements in reporting, upgrading or monitoring frequency, and improvements in plants and operations.

A mobile laboratory developed by the aquatic biologists of EPA Region III is capable of performing static and continuous flow toxicity tests near effluent discharge points. The mobile laboratory is designed to meet the specifications required by accepted methodology as identified in ' Methods for Acute Toxicity Tests with Fish, Macroinvertebrates and Amphibians, ' EPA-660/3-75-009, April 1975. Effluent, pumped to the laboratory , is proportionally mixed with the receiving water and delivered to test containers. Toxicity tests are conducted on different effluent concentrations for a standard 96-hour period; each exposure and controls are tested in duplicate. The fathead minnow is used as the test organism, because it is indigenous to most of the U.S., is easy to maintain and reproduce in the laboratory, and is commercially available. Testing requirements, construction materials, and equipment are discussed. The testing procedure is described. The results of toxicity tests conducted on 11 different discharges from five industrial types show all but two produced some level of measurable acute toxicity. Schematic diagrams illustrate the laboratory floor plan and the laboratory interior. (Davison-IPA) JF - Interstate Commission on the Potomac River Basin, Rockville Md. Technical Publication 78-2.

While the principle reason for this is conceptual soundness and utility, an effective technology transfer program has been central to its continued popularity with engineers and planners in both the public and private sectors. There are numerous key ingredients in the success of this technology transfer program. Included are: (1) good model documentation, including test data, which is updated concurrently with model changes; (2) a simple, informal and responsive mechanism for making the model available to users; (3) workshops to train potential users; and (4) a continuing commitment to maintain the model. Except for the last of these, technology transfer is accomplished with a minimal expenditure of resources. The SWMM Users Group currently numbers some 275 firms and individuals, and meetings feature a wide variety of presentations, including information on the application of a wide variety of models.

The 1977 legislation provides management and resource assistance needed to accelerate rural water quality management programs. Pollutants resulting from nonirrigated crop production include sediment, nutrients, pesticides, and organic matter. Application of irrigating cropland increases the likelihood of runoff and resultant pollution from salts, sediment, and sediment-related pollutants. Confined animal production facilities generate pollution from nutrients, organics, sediment, salts, pesticides, and pathogens. Animals on pasture or range can generate excessive sediment, nutrients, organic matter, and pathogens through elimination of protective vegetation caused by overgrazing. BMPs represent a pollution preventive; this report describes several of them. BMPs for erosion and sediment control on croplan include tillage measures, management of surface and vegetative covers, and soil and water conservation. Techniques for preventing loss of nutrients and pesticides generally involve proper application, optimum dosage, timing, and disposal of unused chemicals and containers. Prevention of overgrazing involves evaluation of the land 's forage capacity, animal grazing habits, soil characteristics and slope.

The study area extended 220 miles upstream from Great Falls to the confluence of the Savage River, and included the following tributaries: Monocacy River, Antietam Creek, Conococheague Creek, South Branch Potomac River, Cacapon River, and Shenandoah River. Study results are reported as estimated tons of plants containing P and N in terms of pounds for the upper Potomac River, Antietam Creek, and Conococheague Creek. The Monocacy, South Branch Potomac, Shenandoah, and Cacapon Rivers did not contain sufficient growths of aquatic plants from which standing crop estimates could be made. It is concluded that the rooted aquatic plants in the upper Potomac basin are not a significant factor in the nutrient budget of the lower Potomac River, because the quantities of P and N contained are equivalent to about 40% of the P and N in the waste waters discharged to the upper Potomac River in a single day.

Controlled amounts of numerous elements were introduced into the feed stream with the aid of a stock solution containing ten different compounds. Details of the relevant pilot plant layouts and flow diagrams are given. The lime neutralization process appeared to be the most economic of the three systems, adequate trace element removal being obtained in all cases with the exception of boron and phosphorus, and none of the three processes was completely effective in removing these two elements.

The contactors, representing various forms of commercially available equipment were the packed column, pressure injector and bubble diffuser versions. There was a highly significant log-log correlation between coliform reduction and ozone utilization for all types of contactor. Only the bubble contactor however was able to achieve the necessary ozone utilization (4.8 mg per litre) consistent with a decrease in the total and faecal coliform counts in the treated effluent to acceptable levels of 1000 and 200 organisms per 100 ml respectively.

The two methods were compared at different applied ozone levels, (3.0, 6.0, 9.0 mg ozone per litre). A significant difference between the two methods was observed only at the lowest dose level, but although the residual levels of coliforms varied appreciably from day to day as a result of variable quality of the influent, there was no overall difference in the results obtained by the two methods.

In addition epidemiological evidence is cited for increases in diseases of viral origin, probably owing to aerosol transmission, in collective farms in Israel which practice spray irrigation of sewage. The prevalence of illnesses of viral origin during the summer was increased, while in the winter when irrigation was suspended the level fell to that obtaining in control communities with alternative methods of disposal. While conclusive evidence of a public health risk is difficult to establish in most cases, the onus should be on the discharger to prove the absence of risk.

A pilot-scale rotary furnace with an afterburner operating at 1000C for fume incineration were employed and the mixed sludge feed was pumped into the furnace at a rate of 100 lb per h. Exhaust gas was scrubbed in a wet caustic scrubbing tower and the exit gases discharged through a stack fitted with a gas burner as an additional precaution. Adequate incineration was achieved, with a combustion efficiency always in excess of 99.99 per cent with a nominal residence time of 2 sec, while levels of kepone in the ambient air did not exceed the provisional upper limit of 25 ng per m3. Precautions designed to prevent the accidental spread of contaminated material at ground level are also outlined. JF - Land Disposal of Hazardous Wastes.

In the first instance, the three main variables tested, at contactor throughputs of 75 litres per min, were contactor design, ozone dose level, and day-to-day variation in effluent quality. Interaction effects between dose level or effluent quality and contactor type were also examined to assess the sensitivity of the comparative behaviour to variations in operating conditions. Data were also subjected to linear and stepwise multiple regression analysis with respect to selected sewage chemical and biological parameters. The results will be published separately.

Following an assessment of the data a scheme for countercurrent water flow from the chiller to the prechiller, washer and scalder in series was implemented at a selected plant and comparisons were made between the chemical and bacterial quality of the final effluents from the recirculating system with that from a once-through system with make-up of fresh water at each stage . The results suggest that although all four stages showed a deterioration in water quality with the countercurrent re-use system, nevertheless the replacement of one third of the total make-up water to the scalder by recirculated water resulted in an improved bacterial quality in the product.

AN - 13559310; 448060 AB - The subject paper (Canale and Squire 1976) presents the results of the application of a steady-state mass balance model to chloride and total phosphorus data for Saginaw Bay in 1974. Richardson (1974, 1976) has modeled chloride in Saginaw Bay on both a steady-state and a time variable basis. In this work, the steady-state model was shown to be inadequate for this system, except during stable periods in summer and fall. Since most of the loading of pollutants to the bay does not occur at these times, the time variable model was developed. The purpose of this comment is to compare similar aspects of these projects and to contrast the steady-state and time variable approaches with respect to their ability to simulate observed phenomena and the utility of their results.

This agency has permit authority in these areas and for underground injection wells, while the Illinois Department of Public Health and the state Department of Mines and Minerals share responsibility for groundwater protection. The State Geological Survey and State Water Survey for groundwater protection. The State Geological Survey and State Water Survey engage in research and resource interest. After the 1970 passage of the Illinois Environmental Protection Act, the state was able to develop solid-waste rules and regulations, and now has sanitary landfills instead of open-burning garbage dumps. Both liquid and special waste may be incorporated into solid-waste landfills in some areas, upon issuance of a special supplementary permit. Direct sanitary landfilling, subsurface injection, surface absorption, consignment burial and land spreading are used.

The Marinette-Menominee Harbor has severe arsenic problems associated with leaching from an adjacent waste storage area. Polychlorinated biphenyl contamination of bottom sediments is common to both Saginaw River and Bay and Waukegan Harbor. Problems related to fish contamination, proper dredging techniques and disposal of bottom sediments are discussed.

Basic approaches to co-disposal include the use of sludge incinerators with the organic portion of solid wastes as a fuel to dry, burn, and reduce the volume of sludge; and the use of a solid waste incinerator, solid waste-fired steam generator, or waterwall combustion unit to burn dewatered sludge. The use of a fluidized bed furnace for co-disposal in an EPA-supported demonstration at Franklin, Ohio, is described. The facility at Franklin was also designed to recover a low grade paper fiber, ferrous and nonferrous metals, and glass from the solid waste stream and to use fuel derived from the non-recoverable organic portions of the waste to operate the sludge incinerator. Th modification of an existing multiple hearth sludge incinerator to accept refuse-derived fuel and operate in either an incineration or pyrolysis mode at a facility in Concord, California, is described. Experiences with the use of a solid waste incinerator as a sludge volume reduction unit are described for Ansonia, Connecticut; Norwalk, Connecticut; Holyoke, Massachusetts; and other municipalities. The direct use of heat from burning solid waste to dewater and burn sludge was demonstrated in Glen Cove, New York.

The specific conflict exists between preservation of white water for recreational purposes and development of the site for a major multiple-purpose reservoir. A simulation model is developed to investigate the storage yield relationship; the model incorporates a lag-one Markovian flow generating model to produce annual flows which are, in turn, disaggregated into monthly flows by using a procedure developed by Valencia and Schaake in 1973. The generated monthly flows are then routed through a simple reservoir model. Results demonstrate that substantial increase in capacity of the New Melones Reservoir may produce generally modest gains in reliability; more importantly, however, the results show how relatively simple analysis could assist in quantifying trade-offs among environmental values and the products of traditional water resources development.

S. drinking water standards, one must start first with the National Quarantine Act of 1878. This act was major codification of the fairly old concept of legislation to control the spread of disease. By 1890, sections of revised quarantine acts were dealing specifically with protection against water borne disease. The 1914 Treasury Standards for drinking water (known also as the first Public Health Service Drinking Water Standards) became the basis for all succeeding revisions of U. S. standards through 1974. Though the first standards prescribed limits on bacteria only, limits on various chemical constituents were added in later revisions as the need became apparent and as the technology for detecting these constituents became feasible. The National Interim Primary Drinking Water Standards effective last June extend these limits beyond interstate carrier systems to more than 240,000 community water supplies. Throughout the world, several basic principles have been applied in setting standards. These include (1) preventing the spread of disease, (2) aesthetic considerations, and (3) determining what degree of monitoring ability and compliance to a proposed standard is economically and technologically possible for community water supply systems.

The chamber was tested with several types of filter membranes; results show that polycarbonate membranes are superior. Experiments were conducted with eight representative species of bacteria, all recently isolated from environmental sources; these included five opportunistic pathogens and three indicators of water quality. Four of the five pathogens exhibited little variation in viable count over a seven day period; the survival rates of the other organisms are outlined. Bacterial viability in seawater is influenced by such factors as temperature, salinity, pH, and availability of nutrients. The survival of E. coli is a function of water temperature. As seasonal temperatures rose, so did fatalities, showing an inverse relationship between survival and water temperature. Since low temperatures may prolong the life of enteric bacteria in sea water, curtailment of wastewater disinfection during the cold winter months is inadvisable for many regions, particularly for those areas used extensively for the production and harvesting of fish and shellfish. Because of the wide variation in the persistence of both indicator organisms and enteric pathogens, marine water receiving treated wastes should be evaluated more closely.

Costs incurred in sewage sludge utilization systems at 15 sites in various parts of the United States are discussed. Cost factors for separate sectors of the process were used to develop a ' model ' community for use in estimating costs and determining economic feasibility of land application. The model community is based on a system that treats an average flow of 10 mgd and produces 800 tons/yr of stabilized sludge as dry solids. Annual costs for land application in such a system are estimated at $27,400 or $35/ton. The total annual operating cost is divided according to labor, fringe benefits, vehicle operation and maintenance, and miscellaneous expenses. The total annual cost of land disposal of sludge is also plotted against average daily raw waste water flow from a linear regression of data obtained during the survey.

Although well seals are buried to prevent problems of freezing or farm equipment running into exposed casing, the practice of burying actually creates more difficulty than it solves. Common methods of elevating casing have many deficiencies as well. Welding a section of pipe on top of the old casing is difficult due to cramped working conditions, and a bad weld can provide an avenue for pollutants. Threading the old casing requires equipment that is not readily available, while ' Dresser'type ' clamp connections yield too easily to lateral and pull-apart forces. Extending casing by using cement joints appears to be one of the simplest, most sanitary and most effective techniques. Laboratory tests at Bucknell University showed that cement joints constructed under simulated field conditions showed more than adequate strength under lateral and axial loads. The cement joint method is not recommended for plastic well casings. (Eberle-NWWA) JF - Water Well Journal Vol. 31, No. 9, p 47-50, September, 1977. 2 fig.

Although chlorination has been the traditional means of disinfection in sewage treatment, the potential toxic effects of chlorine to aquatic life have led to the consideration of ozone as an alternative. Sewage treatment plants in the United States which have used ozone as of 1977 are listed. The use of ozone in the oxygen-activated sludge process and in the removal of total coliforms, viruses, and dissolved solids is described. Pilot plant studies on the use of ozonation prior to activated carbon adsorption have indicated that ozonation can increase removals of dissolved organic carbon compounds, prolong the life of the carbon bed, and result in odor reduction. Current research into the substitution of ozonation for chlorination in water treatment is discussed. Current industrial applications of ozone are examined for the destruction of cyanides and polychlorinated biphenyls and for the treatment of photo-processing, military hospital, and power plant cooling waste waters. Future potentials for ozonation in the United States are evaluated. (Schulz-FIRL) JF - Industrial Water Engineering Vol 14, No 5, p 14-19, September, 1977.

Basic methods of thermal co-disposal include the use of the organic portion of solids as fuel for sludge incinerators and the use of a solid wastes incinerator, solid wastes fired steam generator, or a waterwall combustion unit to burn dewatered sludge. Approximately 200 waste water treatment plants in the United States utilize thermal processes for sludge disposal. The use of a fluidized bed furnace at Franklin, Ohio is described. An EPA-supported demonstration in Concord, California of the use of a multiple hearth sludge incinerator with refuse-derived fuel (RDF) is described. This incinerator, modified to operate in either incineration or pyrolysis mode, is fed RDF mixed with sludge which has a solids content of 16%. incineration and spray drying at Ansonia, Connecticut produces dried sludge which is used by local residents for fertilizer. Incineration and rotary drying are used to dewater sludge at Holyoke, Massachusetts. Norwalk, Connecticut and Glen Cove, New York use incineration and furnace drying for waste disposal. Waterwall combustion thin film drying at Dieppe, France and waterwall combustion flash drying at Krefeld, Germany are described. Co-disposal of wastes is an energy-saving and possible fuel-producing technique of solid waste and sewage sludge disposal.

The fish spawned successfully 39 times in laboratory tanks under a simulated natural temperature and light regime at all DO concentrations tested. Fish at 2.5 mg/liter DO started and finished spawning at earlier dates than those at the higher oxygen concentrations; fish at saturation started and finished spawning at later dates than those at the reduced concentrations. The number of embryos from a single spawning ranged from 14,600 to 155,300. Number of spawnings, viability of embryos, hatching success, and survival through swim-up were similar between control fish and those exposed to reduced oxygen concentrations.

To solve the problem, a multiple approach was used combining laboratory and field studies to determine sources, effects, persistence, and prevention of supersaturation. Classical bioassays were used to determine effect, but additional tests were needed because of the unique nature of supersaturation. These tests included assessment of avoidance capability of fishes, assessment of depth compensation and temperature effects, and field surveys of aquatic organisms distribution in the affected areas. Data from the combined approaches were used to set safe levels for aquatic organisms. In addition, engineering expertise from other groups was applied in an attempt to prevent or mitigate the effects of supersaturation.

Several bands with consistently high concentrations of metals, in association with high organic carbon, have been partially identified and have persisted for at least fourteen months in and adjacent to the southern part of the sludge release site. Polychlorinated biphenyls (PCB's) were widely distributed in concentrations that may be inimical to marine organisms. The time distribution indicated cyclical inputs, possibly from the coastal zone. Localized areas of high impact, associated with other parameters from sewage sludge, have been identified. Mortalities of the mahogany clam, Arctica islandica, were indicated at loci in and near the ocean dumping activity. Detailed bathymetry of the persistently impacted area south of the sludge release site indicates gentle geomorphic features may affect the aggregation of dumped materials. Statistically significant changes of the benthic infaunal communities are occurring in the impacted area south of the sewage sludge release site. A preliminary indication of diseased macrofauna associated with the impacted area was found in February 1977. Molluscan shellfish in the vicinity of the sewage sludge site appear to harbor bacteria of sanitary significance.

Some experts predict the biological death of the oceans within out lifetime if the present trends continue. Several man-made processes contribute to ocean degradation. These include the destruction of natural ground cover by coastal development, the addition of toxic materials to the oceans, and deliberate discharges from ships. Several methods used in controlling operating discharges are explained in the article including the load-on-top technique and structural modification to vessels. the implementation of discharge standards is praised where present and called for where absent. The details of the treaty arising out of the Inter-Governmental maritime consultative Organization 's Conference on marine Pollution are discussed along with possible interpretations. Certain proposals of the united States that would go beyond the international treaty are examined. One area of deficiency in the international arena cited and discussed is that of liability and compensation for oil pollution damage. The authors note that advancements made at the United Nations Conference on the Law of the Sea appear to be negligible.

The Controversy over Section 404, Federal Water Pollution Control Act Amendments of 1972 AN - 60844128; 79J7772 AB - In 1976, both Houses of the 94th Congress passed amendments to section 404 of the Federal Water Pollution Control Act. However, the Joint Committee of the House & Senate was unable to write a compromise amendment, leaving the issue to be resolved during the following Congress. The environmental interests & political forces that led to the deadlock are discussed, & the merits of the various proposals that were considered are presented. Topics under discussion include the controversy of the wetlands, the Breaux Amendment, the Wright Amendment, the Administration's proposed bill, the Baker Amendment, & the Baker-Randolph Amendment. By analyzing the competing economic & ecological policies, a course of action is suggested for the 95th Congress to take in its reevaluation of the section 404 program. The Baker-Randolph bill is found to be the most environmentally responsible. Modified HA.

Mn++ failed to affect dopamine levels at concentrations of up to 2000 mg/liter of drinking water and six months of continuous exposure. A second objective of this work was to study the biological interactions between Mn++ and sodium hexametaphosphate ((NaPO3)6) administered simultaneously in drinking water. Some evidence was obtained that high concentrations of (NaPO3)6 depleted tissue Mn ++ and produced decreased body weight gains over the experimental period. Similarly, Mn++ in high concentrations resulted in decreased growth of weanling animals. Stoichiometric combinations of Mn++ and ((NaPO3)6) prevented the decreased rate of growth produced by either agent alone. On the basis of these results, we conclude that Mn++ in drinking water presents little hazard in terms of central nervous system involvement in a homogeneous population.

Gravity separation, solvent extraction, adsorption, combustion, and filtration are described. The demonstration treatment system was made up of four main systems plus an impounding reservoir. The water treatment unit reduces the organic COD of water impounded in the refinery prior to discharge. It consists of 12 identical adsorber cells, each cell containing a 4 m deep bed of carbon having a dry weight of approximately 22,100 kg supported by gravel. The carbon regeneration system utilizes selective oxidation of the organic impurities in the pores at high temperatures (900-970C) and with a controlled low oxygen atmosphere in a multiple hearth furnace. During the two-year project, 172,040,000 gallons of water was processed to load 747,000 kg of carbon with 165,000 kg or COD. The overall operating cost was 49 cents per 1000 gallons of water treated, or 524 kg of COD removal from the water. During the second year, the plant demonstrated the ability to operate at 40 cents per 1000 gallons of water treated.

The principal advantage of remote sensing is its ability to examine the whole picture at once; it is also more cost-effective than more conventional monitoring techniques (an important consideration since resources required to perform all of the monitoring needed are unavailable). The present form and strategy of the remote sensing program is described in terms of providing operational remote sensing support and developing advanced techniques to meet critical monitoring needs. Three types of remote sensing: earth reflected differential absorption systems, airborne light detection and ranging (LIDAR) systems, and laser fluorosensing systems can be used for oxidant transport studies, plume inventories, plant siting studies, model verification, measuring inversion layer height, determining plume dimensions, positioning other monitoring platforms, supporting model efforts , characterizing oil spills, determining vegetation stress, monitoring selected water pollutants, mapping chlorophyll, and studying dye dispersion.

The proposed impoundment will have a normal pool area of 387 acres and will drain 29,658 acres. Agricultural and livestock production and natural conditions are the only pollution sources; potential pollution problems are foreseen in the E-5 and E-6 arms. Fecal coliform densities ranged from 130-5600/100 ml in May and 100-2200/100 ml in August. Salmonella were isolated at four of five stations sampled in May. Nitrogen and phosphorus concentrations were occasionally high. Postimpoundment water quality was predicted by the Hydrocomp Simulation Programming model; no major violations of Georgia water quality standards were forecast. Major conclusion: (1) High fecal coliform densities plus Salmonella isolations represent stormwater runoff under free-flowing stream conditions; following impoundment retention, time will decrease both parameters and should produce water quality suitable for body contact recreation. (2) Eutrophication potential will depend on such nutrient source control factors as assimilation by swampy areas. (3) Attempts should be made to contain runoff from livestock feeding areas and to limit fertilizer use.

Whitehouse, Florida AN - 19205368; 7907778 AB - An on-site treatment process was developed for six abandoned waste oil pits in Florida which contained high levels of polychlorinated biphenyls (PCB). Sampling of the ponds, which had a total surface area of about 5 acres and depths ranging from 5-15 ft, indicated they contained a bottom layer of thick oily sludge underlaying a layer of water and covered by a layer of oil. Pit pH was 1.0, permitting the PCBs to be soluble in the oil/water mixture. PCB concentrations in the sludge samples ranged 8.7-23.3 ppm and significant levels of copper, lead, zinc , cadmium, and chromium were measured. To reduce PCB levels to within 1 ppb, activated carbon was selected. Because adsorption columns were not considered practical in this instance, a powdered activated carbon adsorption system was developed which incorporated a collection sump, a carbon mixing chamber, a sedimentation basin, and a sand filter. The sump drained the pits into the mixing chamber where carbon was added at 27 ppm to the influent. The carbon-PCB sludge was then transferred to a 22 ,500 gal stabilization basin for at least 6.25 hrs, followed by filtration through a sand filter. The treated effluent was discharged into the St. Johns River.

Resins and other solids of varying specific gravity and particle size were tagged with a metal salt or fluorescent material and added to a waste stream as a synthetic suspended solid to determine the collection efficiency of the samplers. Recovery of the metal salt or fluorescene was used as the indicator of solids recovery. A 832 ,000 liter/day (220,000 gallon/day) raw domestic wastewater flow was used to conduct the test. Recovery of solids in the hydraulic jump below the Parshall flume, and at the 0.6 depth in the approach channel above the flume was 25% below the theoretical homogeneous concentration indicated by the resin feed rate. The results indicate the need for a method of evaluating the wastewater characteristics for proper sample intake tube placement.

The system provides for simultaneous injection onto two independent columns equipped with individual detectors. The gas chromatographic output is processed by the computer into a report for each column, listing the names and concentrations for compounds of interest. The system has sufficient reliability to allow detection of chlorinated pesticides at the picogram level and organophosphorus pesticides and phthalates at the nanogram level. This system can be readily incorporated into currently accepted methods for pesticide residue analysis, and once the system is calibrated, 42 samples can be analyzed for 45 parameters without operator intervention. Use of the semi-automatic pesticide analysis system will enable more effective use of available manpower in water monitoring programs. The system has been employed successfully to analyze drinking waters, surface waters, waste waters, biological (fish) extractions and sediment extractions.

VOC emissions from vacuum producing systems may be controlled by passing non-condensable vapors to a fire-box, incinerator, or to a compressing system. Waste water separator emissions may be minimized by covering forebays and separator sections; types of covers suitable for these areas are described. Process unit turnabouts, such as shutdowns, repairs, inspections, and start ups, may incorporate systems where vapors are added to the fuel gas system, flared, or vented to the atmosphere; VOC emissions will be minimized if vapors are combusted with fuel gas or flared until the pressure in the vessel is close to atmospheric pressure. An economic analysis of control systems considers all the technical parameters used in developing control costs. The impacts of these emission control technologies on energy and the environmental are discussed briefly. Regulatory aspects reviewed include the identification of plants to which regulations would apply, the selection of an appropriate format, and recommendations for compliance and monitoring techniques.

Volume 3. Summaries of Technical Data for Combined Sewer Overflows and Stormwater Discharge. 1976 Needs Survey AN - 19193610; 7901308 AB - A well defined, consistent nationwide methodology was applied for development of present and 1990 capital, operation, and maintenance cost estimates for combined sewer overflow correction and control of storm waters. Estimates were based on attainment of quality criteria in the areas of esthetics, Fish and wildlife, and recreation. A computer model, called the Needs Estimation Model for Urban runoff, was developed from intensive work with the literature of a detailed analysos of ten specific urbanized areas. The model calculates the combined sewer and stormwater control needs for each urbanized area and then these estimates are summed on a state and territory basis to provide national estimates. The estimated needs obtained using this model are significantly lower than those developd by earlier surveys as a result of the following factors: (1) consideration of receiving water assimilative capacity; (2) a relatively small design storm; (3) a well defined area for storm water control; and (4) a nationwide consistent methodology. Cost estimates for treatment and/or control of stormwater discharges are of better quality variables affecting costs in this area.

Radioactive mercury-203, in the forms of mercuric acetate, methylmercuric chloride, and phenylmercuric acetate, were used. Two distinct varieties of the garden pea Pisum sativum were used, a dwarf variety, Little Marvel, and a normal variety, Alaska. The seeds were planted in soils contaminated with the mercury compounds. After maturation, stems , leaves, and pods were harvested and analyzed by gamma spectroscopy. Utilizing a least squares three-way analysis of covariance coupled with a Studentized Range Test, significant differences were noted among the levels of the three mercury compounds in the plants, between mercury levels in the two pea varieties, and among mercury levels in the different pea tissues examined. Phenylmercury levels differed consistently from levels of ionic mercury and methylmercury, suggesting a separate pathway for it in peas with regard to metabolism and storage.

The high temperature of the waste water was a critical factor which influenced all phases of operation. Warm sewage seemed to cause nitrification in the plant even though the facility was not designed to nitrify. Settleometer tests indicated the formation of extensive gas bubbles, probably nitrogen, which caused excessive floating of sludge in both the settlometer and the clarifier. Recommendations are made to reduce the degree of nitrification. A carefully controlled sludge wasting program should be established during start up, and the system may need to operate at less than design hydraulic detention times. The final clarifier should operate to minimize sludge detention times. One or more of the reaeration basins may be used as an N2 stripping basin. Process control tests and data analyses should be continued to further process control analyses.

The filtration media consisted of anthracite in particle sizes ranging 1.0-2.0 mm, with or without sand with effective particle sizes of 0.4-0.9 mm. The media depth in the filter was varied over 38-64 cm for the anthracite and 30-38 cm for sand. Hydraulic loadings on 0.1 sq m filters were varied over 3-9 gpm/sq ft. Breakthrough of suspended solids in the activated sludge treated waste water occurred during tests with single media anthracite with particle sizes of 1.65 and 2.0 mm. Breakthrough was observed to increase at higher flow rates. With a dual media of 2.0 mm anthracite and 0.9 mm sand, higher quality effluent was obtained with higher suspended solids loadings and longer run times. Backwashing tests of the dual filter media demonstrated that a 13% bed fluidization at a 35 gpm/sq ft flow rate was effective in cleaning. The growth of filamentous organisms and Nordica species interfered with some of the experiments, as did low suspended solids concentrations in some of the activated sludge influent.

Research and development are now underway to reduce uncertainties of oil shale production costs, sources of capital, competition from other oil sources and other energy sources, and environmental costs. Most of the oil shale (and the most valuable part) is found largely on federal land in the Green River Formation of Colorado 's Piceance Basin (85% of western high grade shale), Utah 's Uintah Basin (10%), and in Wyoming (5%). An estimated 80 billion barrels of oil can be recovered using current technology, and 800 billion barrels may ultimately be recovered. The oil is extracted through heating, which breaks the chemical network and cracks the heavy kerogen molecules into smaller molecules. This releases the valuable liquid hydrocarbon mixture, combustible gases, and a coke-like residue. Recovery of one barrel of shale oil uses 2-6 barrels of water, 1-2 tons oil shale, and 100 sq ft of land and produces .33 lb airborne dust, 2.5 lbs polluting gases, 2-5 gal contaminated water, and 1-1.5 tons spent shale. A one-million bbl/day operation, including towns, will occupy about 80,000 acres of land. Direct effects include land and habitat disruption, dust and gas air pollution (currently exceeding federal and state standards), surface and groundwater depletion, increased river salinity, and possible water pollution.

A detailed evaluation is presented of data acquired prior to, during, and after recovery operations. An initial recovery effort conducted by EPA resulted in a 30% removal of the PCB. The Corps of Engineers removed the remaining Aroclor using a Pneuma dredge, thus increasing the total PCB recovered to approximately 92%. The second recovery effort was conducted without significant redistribution of toxic materials and bacteria associated with the dredged sediments. No appreciable amount of PCB returned from the disposal ponds to the river because of the design of the land disposal area and the use of a filtration-adsorption treatment unit. Water, which drained from the dredged spoils in the disposal pond, contaned some Mn, N-NH3, N-TKN, oil and grease, and total coliform, but only traces of Cd, Fe, Zn and total P. Apparently most of the pollutants and bacteria were associated with or scavenged by particulate matter and settled in the disposal ponds. Only small concentrations of toxic materials, nutrients, and suspended solids were observed to be released into the overlying river water during dredging operations. The release of pollutants from sediments during dredging could be only partially predicted by use of the elutriate test and evaluation of the interstitial water. The elutriate test was valid for most metals, nutrients, and oil and grease, but both tests failed to predict the amount of PCB released.

Septic tank pumpings, generated at an estimated volume of 13 million cu m/yr , were introduced into a 1,980 gpd activated sludge pilot plant on a continuous flow basis and on a shock load basis. Batch aeration tests were also conducted for the shock load studies. A control unit treating only primary effluent was also operated over the four month study period. The municipal activated sludge pilot plant was able to accommodate both continuous and intermittent loads of septic tank wastes without significant interference with effluent quality. While the strength and organic loading of the septic wastes introduced on a continuous feed basis influenced the response of the activated sludge system, wastes with COD levels below 3 g/g mixed liquor volatile suspended solids/day did not disrupt treatment performance. Unacclimated activated sludge systems were also able to accommodate septage. Results of the study also indicate that sufficient excess aeration, especially for shock septage loads, and adequate sludge handling facilities are necessary for municipal activated sludge treatment of septic wastes.

The EPA neutralization facility at the Crown Mine Drainage Control Field Site near Morgantown, West Virginia, contained two parallel treatment trains in which acid mine drainage could be cycled from the turbine flow meter into: (1) a lime reactor, an aerator , and a thickener; (2) a limestone reactor, an aerator, and a thickener; or (3) a limestone reactor, a lime reactor, an aerator, and a thickener. Limestone neutralization was investigated as an alternative to lime treatment because of its cheaper costs and low-volume, high-density sludge. With limestone treatment, most effective neutralization was at a 20% sludge recycle rate, a pH value near 7, a 30-min detention time with vigorous mixing in the reactor, 4-6 hours detention in the aeration system, and the addition of coagulants at a 7 mg/liter rate. Lime treatment involved a 7-min reaction time, less than a 2-hr oxidation time, and a coagulant addition of 5 mg/liter. Although the limestone process was effective under certain conditions, the process was considered infeasible for general application to acid mine water containing more than 50 mg/liter of ferrous iron.

The study was requested by the Five County Association of Governments, the local ' 208 ' water quality management planning agency. Water, sediment, and benthic samples were collected at selected locations throughout a total stream reach of 174 km. Study results indicated a gradual degradation of water quality downstream from Zion National Park. Violations of recommended criteria/standard levels were most common for the salinity parameters, but concentrations of arsenic, iron, manganese, and mercury also exceeded recommended levels. In addition, high concentrations of suspended solids impaired the quality of water throughout much of the study area.

Also, emphasis on detailed daily logs of operation conditions and trend charts, was stressed for future operation. There were some problems with denitrification. After additional training of personnel, the oxidation ditch effluent BOD and total suspended solids level were expected to improve. Toxic substances were to be eliminated from the sewer system. If problems continue with denitrification, surface skimmers may need to be installed on the final clarifier.

The municipal plants surveyed were small to medium in size with throughputs of less than 100 mgd. A cost analysis indicated that landspreading liquid sludge was far less expensive than landspreading sludge dewatered by vacuum filtration. Communities that disposed of liquid sludge had an average cost of $32.00 per dry ton, while those that dewatered their sludge averaged $87.00 per dry ton. Personnel costs represented the largest single cost item for both liquid and dewatered sludge landspreading. Liquid sludge was more acceptable to farmers than dewatered sludge because the municipality spread the liquid sludge. Dewatered sludge was more difficult to spread.

Present ground water monitoring programs, however, were designed mainly to assess the quantity and quality of ground water available for a particular use. To prevent contamination of ground water resources, a monitoring program must go beyond this and must provide a systematic approach to detecting and delineating ground water pollution before the pollution reaches the point of use. In response to this challenge, a monitoring methodology has been developed under the sponsorship of the U.S. Environmental Protection Agency. The methodology is briefly discussed and the published reports that contain details on it are summarized and referenced.

The Agency recently signed a consent decree (June 1976) as a result of litigation brought about by five public interest groups. The consent decree requires the EPA to establish revised effluent limitations and standards regulating the discharge of up to 65 classes of pollutants from pulp, paper, and paperboard mills and converting plants. The regulations must be promulgated within three years and would be applicable to new facilities, to existing facilities (on or before 1983), and to users of publicly owned waste water treatment facilities.

The method (described in the appendix) employs potassium fluoride and potassium pyrosulfate fusions to compose a 10-gram sample, barium sulfate precipitations, solvent extraction and electro-deposition to isolate the plutonium, and alpha spectrometry to measure the plutonium. The single laboratory evaluation demonstrated that the overall within-laboratory precision of the method can approach the precision of nuclear counting statistics alone. The interlaboratory collaborative test showed the coefficient variation representing differences between laboratories to be approximately 10% for concentration levels exceeding one disintegration per minute per gram. Also discussed are several problem areas associated with environmental actinide analyses, including difficulties that may be anticipated in requiring monitoring laboratories to adopt a specific complex method of this type. Suggestions for improving agreement between laboratories include establishing criteria for analytical results rather than requiring specific methodology.

Costs are assessed for chlorine, chlorine dioxide, and ozone as direct disinfection agents. The cost of aeration as a means of removing chloroform and other trihalomethanes (the potentially carcinogenic by-products of chlorination) is examined. An in-depth analysis of the costs associated with the use of granular activated carbon as a general means of removing organics is prepared; costs both with and without separate contractor systems and an examination of the possible cost savings associated with regional regeneration are included. The costs presented are intended for the development of planning estimates only and not for the preparation of bid documents or detailed cost estimates. Exact capital and operating costs are location-dependent and highly variable. Costs are presented to facilitate adjustments to the reported costs when local information is available. Standardized levels for a selected set of design parameters are assumed and sensitivity analysis is performed for the majority of the parameters. The values for 1, , 10, 100, and 150 mgd plants for all treatment alternatives examined are given in a table. Chlorination was found to be the cheapest of all the treatment technologies.

Economic welfare concepts are related to major phases of the fishing industry, and empirical estimates of these values are surveyed in the literature. The exvessel price of landed species is cited to be a conservative estimate of net benefits realized by all phases. The literature survey reveals that most economic studies of fishery benefits are conducted without any apparent knowledge of valid welfare concepts. This gap between empirical and theoretical constructs must be eliminated if economic values are to be plausible and meaningful.

This legislation includes the: (1) Federal Water Pollution Control Act Amendments of 1972; (2) Toxic Substances Control Act; (3) Resource Conservation and Recovery Act of 11972; (4) Federal Insecticide, Fungicide, and Rodenticide Act; (5) Federal Environmental Pesticide Control Act of 1972; (6) Atomic Energy Act of 1954; and (7) National Environmental Policy Act of 1969. There are other statutes which have some bearing on groundwater quality protection--for example , court interpretations of statutes protecting Indian water rights, executive orders, and control of groundwater quality protection on Federal lands and Federal facilities. It would appear that, for most situations in which federal action is involved, some consideration of groundwater quality is authorized.

The legal status of the regulations is reviewed, and food industry studies are reviewed. Legal issues include jurisdiction, and ranges of limitations for certain plants versus national uniform standards. Influences and constraints which may affect food processing regulation include the energy shortage and other environmental legislation. The requirements of the Federal Water Pollution Control Act Amendments (PL 92-500) and other environmental legislation have sparked interest in the recovery reuse, and conservation of process wastes and water. There is an increasing trend toward by-product recovery, reuse, recycle, and water conservation, along with end-of-pipe treatment.

These substances may cause clogging of sewer systems, creating maintenance problems, and they may impede treatment processes. In addition, they may cause sheens, surface and sediment deposits, and produce long term BOD which depletes dissolved oxygen in streams. It was hoped that a linear relationship could be established between FOG and BOD5. Parameters of the defining line were used to calculate the expected BOD5/FOG ratio to obtain FOG limits so that BOD5 would be the limiting factor for readily degraded wastes. FOG limits would be reached first for slowly oxidizing wastes or those which oxidize at extreme receiving stream conditions. Data resulting from investigations revealed the existence of significant relations for the parameters. The amount of BOD5 attributable to FOG could not be inferred from the results, but BOD5 did increase linearly with FOG values. There was appreciable scatter about the regression line. There was no difference between regression lines for industrial and sewage treatment plant effluents. It was concluded that neither BOD5 nor FOG would be sufficient as a single parameter. A dual standard, using BOD5 limits for degradable FOG and FOG concentrations for poorly oxidizable wastes, was suggested.

Two objectives of watershed management for municipal water supplies are: to maintain or enhance water quality through the control or elimination of contamination sources, and to maintain or improve total water yields from watersheds. The former receives the greater attention. Physical contaminants, chemical containments, and microbiological contaminants are the major pollutants. There should be adequate control of turbidity, color, temperature, setteable solids, taste, and odor. Measures should be taken against municipal and industrial wastes discharges, and other chemical contaminant sources such as agricultural runoff and roadway runoff. Diversion of storm runoff can be helpful in these instances. Recreational uses of watersheds could be prohibited or limited to prevent contamination from all classes of pollutants. Primarily, frequent analysis and inspections and a knowledge of contamination sources are needed to ensure watershed water quality.

AN - 17988273; 5260770 AB - Temp, salinity, bottom-sediment type, and zinc concn all influenced Cd uptake by 4 marine bivalves (Mya arenaria, Mytilus edulis, Mulinia lateralis and Nucula proxima) in short-term static assay systems using Super(109)Cd as a tracer. The experimental system consisted of aquaria containing 20l of seawater maintained under controlled light and temp conditions. The water contained either 5 or 20 {mu}g /l Cd and tracer. Distribution and kinetics of the metal were monitored in the water column and organisms. The results demonstrate that Cd uptake rates differed widely among the organisms tested. An increase in temp increased Cd uptake rate by all test organisms. A decrease in salinity increased Cd uptake by all organisms tested. The presence of bottom sediment depresses Cd accumulation in some benthic animals. Zinc in concns of 0.5 mg/l substantially decreased Cd uptake by M.edulis and M.lateralis. It is suggested that all important spp and environmental variables be considered when studying heavy-metal uptake by marine organisms or when establishing water-quality criteria.

Possibly, its most important aspect is that of specifying that there should be an On-Scene Coordinator (OSC) to serve as the single Federal executive agent on-scene to direct cleanup and removal operations. The plan accomplishes its purpose by establishing a flexible organization consisting of the OSC and advisory groups capable of providing expertise and assistance as required. Generally, Federal On-Scene Coordinators are furnished by the Coast Guard for the coastal waters, the Great Lakes, and ports and harbors, and by the Environmental Protection Agency (EPA) for inland waters.

Some of the specific effects that oil has on living systems or populations include but are not necessarily limited to, the following: death as a result of coating and asphyxiation; death through contact poisoning, death from exposure to water-soluble toxic compounds; destruction of sensitive juvenile forms; destructions of food sources or support populations, incorporation of sublethal amounts, resulting in the reduced resistance of species to infection or stresses; and incorporation of sublethal amounts, producing an off-flavor or taint in exploitable species, thereby causing an economic loss to man.

First, the Federal Environmental Protection Agency was created, centralizing responsibility for water pollution control. Second, the Federal Water Pollution Control Act Amendments of 1972 were passed. Concern about non-point pollution sources also emerged at this time. The 1972 Act contains provisions that encourage public participation in pollution control. In addition, it calls for an annual assessment of statewide water quality problems and authorizes federal resources to solve the problems. The water quality management section of the Act, the most comprehensive part of the Act, provides information for sound decision making by state and local officials and is the only authority under federal law to control non-point source pollution. Section 303 of the Act establishes water quality goals and standards for water quality improvement; section 402 implements a rational permit program to control the discharge of pollutants into waterways from point sources. It also contains enforcement provisions. Section 404 authorizes the Corps of Engineers to issue permits for discharging dredged or fill material.

Recommendations were presented for handling the hide in an efficient manner. Various chemical and biological treatment processes for production waste streams were discussed in terms of the different process steps involved. Automatic control of solution quantities and computer calculation of variables, such as times, weights, temperatures, and ingredients were suggested. Reusing purified water and reclaiming chemical and metal resources were primary concerns. Two processing systems were considered for the pollution treatment section. One was a conventional physical, chemical, and biological process. The other employed dilution with a silt laden stream. It was noted that this tannery design was a hypothetical one which assumed unlimited financial resources for implementation.

The 1972 Federal Water Pollution Control Act Amendments were badly needed. They have far reaching results for industry, government and the public. The National Pollutant Discharge Elimination System (NPDES) program is a major new source of regulation. This is a permit program based on effluent requirements. Schedules for control of effluent are also included. The program calls for state-federal implementation and enforcement. The permit is treated as if it were a contract. The past laissez-faire arrangement between polluters and administrators is gone. Penalties include fines of $25,000 per day and one year in jail for the first offense and $50,000 in fines and two years in jail for subsequent offenses. A major effort is needed to increase public awareness of pollution control and clean-up legislation. These amendments may accomplish this, as they provide for citizen suits and the awarding of court costs and attorney fees to either side.

There are six bases upon which a facility may be listed for noncompliance, all indicating some type of court action having been taken against it. A facility might also be listed as ineligible under conditions which do not include a conviction. There is some dispute over this due to unclear legislative history, but the EPA sees its actions as justified. The Office of Federal Activities administers the program. A breakdown of responsibilities within the EPA and the procedure for listing are also set out. The program could be of real value if the EPA moved to ensure that all products come from facilities in compliance. ' National goals clauses ' could be put in contracts between the government and facilities to implement this. The procedure has been used twice as of November 1976 against unconvicted violators, and this could be an effective leverage for speedy compliance.

The author discusses the background of the decree and evaluates the progress that the Environmental Protection Agency (EPA) has made towards implementing toxic pollutant control. The statutory framework of the FWPCA is explored, and the EPA 's initial efforts to control toxic pollutants is reviewed. The evolution of the integrated toxic strategy resulted in an industry approach implementing effluent limitations and pretreatment standards. The program following the consent decree has resulted in major steps forward in the implementation of the FWPCA, First, standards were finally promulgated under Section 307 (a). Second, the scope of regulation of toxic pollutants has broadened and become more effective since the EPA has begun to implement numerous sections of the FWPCA. Finally, the emphasis on regulation of toxic pollutants reflects the priorities stressed by Congress and President Carter.

Any attempt by a coastal state to influence the development and transportation of Alaskan crude oil, presumably based on the constitutional exercise of the state 's police powers aimed at protecting the quality of its coastal waters, would raise a number of legal issues. The issues include: (1) what is the current jurisdictional framework of federal and state relations regarding the transportation of crude oil in the coastal zone; (2) what are the federal constraints upon the exercise of state power; (3) what bases exist for state control of the marine transport of oil; and (4) what effect will the national Coastal Zone Management Act of 1972 have on the balance between state and federal power in the coastal zone. Examined in this context are the Federal Water Pollution Control Act Amendments of 1972 and the Trans-Alaska Pipeline Authorization Act. The author concludes that the issue of defining the relative roles that state and federal governments should play in controlling oil transportation in the coastal zone has yet to be determined by the courts.

The program was designed to overcome environmental problems of sludge utilization and disposal options. The present state of the art is adequate to dewater sludge, and incineration is well established except for air emissions control. Coincineration of sludge plus solid waste and pyrolysis technology are just emerging. Technological gaps which exist and are being studied include the high costs of sludge processing and disposal, and methods for converting sludge into beneficial by-products. Other problems include limited confidence in the efficacy of local industrial pretreatment programs for metals removal, lack of understanding of the risks of land application, and lack of sure methods for the removal of toxicants at the treatment plant.

It is a pioneering effort in collaborative planning among the federal government, the states, and local communities for use of the land. All thirty coastal states and three of the four territories are participating in the voluntary program established by the law. The goal of the program is to encourage the states to balance needs and make deliberate choices among myriad claims on coastal resources. The basic role of the Environmental Protection Agency (EPA) under the CZMA is to participate in the development of management plans and to insist that the Secretary of Commerce not approve a management plan unless the EPA 's views have been ' adequately considered ' by the state. One of the EPA 's major responsibilities is to issue permits for acitivities which affect the coastal zone. However, permits are to be issued only if the activity is consistent with approved state management plan. Since, the water quality control requirements of the Federal Water Pollution Control Act are the primary control mechanisms in the coastal zones, these standards may not be altered by the states under the CZMA planning authority.

While food availability possibly restricted B. longirostris, other species were not affected by this parameter. Algae were consumed in only small numbers and did not contribute significantly to density changes in the plankton. Light and predation had little influence on all species.

Since raw leachate frequently contains levels of heavy metals in excess of those permitted by the official drinking-water standards, strenuous efforts must be made to prevent leachate from contaminating ground-water systems utilized for public water supplies. Iron, although not toxic to man is invariably present in leachate and serves as a useful visual index of contamination from solid wastes. JF - Disposal of Residues on Land.
