Completion Report Doehring, Donald 0., Fabos, Julius Gy, Smith, Mark E. June 1975 35 pages ABSTRACT: The relation between land use changes and flood expectancies in southeastern New England is examined. The common assumption that urbanization affects only flood plains related to low return period events is also evaluated with respect to this region. Watershed morphometry, surficial character, and land use were considered to be the most important independent variables which could be quantified. Morphometry was taken from U.S. Geological Survey 789 quadrangles; surficial properties were derived from U.S.G.S. geologic quadrangles, Soil Conservation Service soils maps, and supplementary topographic map interpretation; and land use data for 1952 and 1972 were acquired from the Massachusetts Map Down series. The dependent variable and index of change in flood expectancy, is conceptualized as a response to land use change; morphometry and surficial character of a given basin are conceived as factors which condition the primary response. Mathematical models which were erected by multiple regression techniques are useful for predicting change in flood expectancies and account for more than 97% of the total variance.

Goodman, Joel M. 1975 19 pages Pub. in Environmental Law, v5 p727-738 1975. ABSTRACT: During the past five years there has been evidence of an extensive change in the perception of requirements for natural resource management at all levels of community organization. These changes have resulted in concerted efforts to better plan the utilization of these limited and occasionally unique environments. Amongthe more obvious resources of this type is the coastal zone which includes: (1) The upland, the traditional habitat of man and his institutions; (2) the water, an a r t i f i c i a l l y bounded (politically speaking) common resource; and (3) the meeting place of the two, the shoreline, a physically dynamic linear resource Delaware has been a leading proponent of improved coastal zone management and has undertaken a number of programs designed to help achieve the goal of wisely using these resources.

Graduate School of Public Health,.and Johns Hopkins Univ., Baltimore, Md. School of Hygiene and Public Health. ABSTRACT: The relationship between carbon monoxide exposure and heart attacks was studied in Baltimore, Maryland. Four hypotheses were tested: (1) Is there a relationship between sudden death and myocardial infarction and ambient carbon monoxide levels. (2) Are postmortem carboxyhemoglobin levels higher for ASHD sudden deaths as compared to sudden deaths from other causes. (3) Are there differences in postmortem carboxyhemoglobin levels between ASHDsudden deaths and living controls. (4) Is there any difference in the pathologic characteristics of ASHDsudden death with high or low carboxyhemoglobin levels. There was no evidence of clustering of either myocardial infarction or sudden ASHDon a specific day, nor between the number of cases per day and ambient carbon monoxide levels.

Completion Report Gates, Charles, D., Haith, Douglas A. 1975 90 pages ABSTRACT: Field, laboratory and s t a t i s t i c a l methods were used to study the influence of certain land uses on the waterborne export of certain wastes from a sewered urban area and from unsewered rural watersheds. Comparison, by means of mass balance analysis, of the amounts of biodegradable wastes in the Susquehanna River at stations above and below a 20.6 square mile developed area in Broome County, N.Y. indicated that the study area contributed carbonaceous BODBat the rate of 390 pounds per day per square mile to the River, averaged over the June-August 1973 and 1974 periods. The nature of the

relationship between land use in and plant nutrient outputs from eighteen rural watersheds in the Cayuga Lake Basin was studied through use of regression analysis. The development of regression equations for nitrate and phosphate outputs from individual watersheds did not lead to the development of un-ambiguous quantitative relationships between land uses and nutrient concentrations.

Office of Water Research and Technology, Washington, D.C. Virginia Univ., Charlottesville, Dept. of Environmental Sciences. Hornberger, G.M., Kelly, M.G., tederman, T.C. September 1975 102 pages ABSTRACT: This research project developed a mathematical model of a lake ecosystem and then tested its ability to indicate what ecological changes - ib particular eutrophication - would result from changes in the physical environment. The model was developed using a digital computer. In situ, enrichment experiments then were performed to assess the relationship between nutrient concentrations and the growth of phytoplankton. The model did deomonstrate that i t could provide useful qualitative information, A diversity index holds l i t t l e promise for use as a quantitative indicator indicator of eutrophic conditions. Growth parameters can be estimated on the basis of careful laboratory experiments, but extrapoiation of this data to field conditions proved questionable. Each model must be carefully designed for each specific application. PB-248 049/CCS NTIS Prices: PC$S.50/MF$2.25

ABSTRACT: EPA is conducting a research program on halocarbnn air pollutants and their possible interaction with stratospheric ozone. Principal compounds under study are fluorocarbon-ll, fluorocarbon-12, fluorocarbon-22, carbon tetrachloride, methyl cholorform, perchloroethylene, trichloroethylene, dichloroethane, methylene dichloride, and methyl chloride. Laboratory studies concern the rates of decomposition of these pollutants in the air and the identity and fate of their decomposition products. Field studies involve measuring concentrations of halocarbons and their decomposition products as functions of altitude and distance from sburces. Fluorocarbons are discussed in detail, with regard to emission sources, current control technology, and possible chemical substitutes. Problems of emissions control and EPA's regulatory authority are reviewed and the economic impacts of several regulatory options for fluorocarbons are considered.

Ramachandra, Rao, R. G. Srinivasa, Kashyap, R. L. August 1975 121 pages ABSTRACT: The ground water level fluctuations in an aquifier are affected by external causes such as precipitation, outflows from the aquifer, and pumping from the aquifer. Stochastic models are proposed for the fluctuations in ground water levels. Both multiinput-single output and multivariate models have been considered. In the univariate models, variables such as precipitation, stream flows and others which have been known to affect the ground water levels have been considered as external inputs. The fluctuations in ground water levels and the casual variables are directly built into the multivariate model. The parameter estimation and the residual tests are discussed in detail. The multivariate model was also tested by simulation. The results indicate that the ground water level series can be successfully modeled by stochastic models. These models can be used to evaluate the time lag between precipitation and changes in ground water levels, the effect of the streamflows on water levels in adjacent wells, and the ground water resources in a region.

INNOVATIVE TECHNOLOGIESFOR WATER POLLUTION ABATEMENT Water Purification Associates, Cambridge, Mass. National Commission on Water Quality, Washington, D. C. Final Report December 1975 544 pages ABSTRACT: The 1985 goal of the Federal Water Pollution Control Act of 1972 (P.L. 92-500) calls for the elimination of discharge (EOD) of pollutants. Innovative technologies capable of achieving or approaching EOD are examined and include land treatment, membrane separation, adsorption thermal separation, chemical oxidation, and suspended matter removal. Various options are examined for ultimate disposal of the pollutants removed from the wastewaters. The study indicates that innovative technologies can achieve or closely approach EOD for municipal and all major industrial sources. Costs generally f a l l in the range of $I to $S per I000 gallons (1973 dollars) but higher costs may be experienced for some technologies

in certain applications. Lower costs generally apply for land treatment systems where conveyance is not excessive. Land treatment alone does not achieve EOD but must be supplemented with other technologies to achieve salt ren~val. Research and development over the next decade should be directed to membrane separation, adsorption, land treatment and residuals disposal.

The principal elements of the model are {1) A data base describing the community's geography, population distribution, and typical building construction; (2) e date base describing the location and strength of noise sources; (3) energy summation of noise levels from each source at many locations; and (4) use of noise level versus human response transfer functions to determine the number of people adversely affected by this noise level. Summingthese for the whole community and dividing by the total population results in a tRolse Impact Index (NIL}' indicating the quality of the noise environment. Three basic types of countermeasures may be applied: (1) source reduction, (2) source rerouting, and {3) pathreceive treatments.

Final Report

July 1975 69 pages ABSTRACT: The report is a review and evaluation of the current knowledge of cadmium in the environment as related to possible deleterious effects on human health and welfare. Sources, distribution, measurement, and control technology are also considered. Cadmiumis widely distributed in the environment. The air over urban areas has contained generally less than O.l microgram per cubic meter, 24-hour average, but a 24-hour average as high as 0.73 microgram/cu m has been measured in the air of a community with a known cadmium source. The cadmium content of water generally is less than 1 part per billion although much higher values have been found. The cadmium content in foods varies widely. The estimated intake from foods is 25 to 75 micrograms per day. Food and tobacco smoke are the major sources except in the immediate vicinity of major sources of atmospheric emissions of cadmium.

produces 23 cm of runoff; whereas in northeastern Colorado, 37 cm annual precipitation gives only 5.B cm of runoff. Large applications of runoff liquid, up to 91 cm on grassLadino and 76 cm on corn in Nebraska did not decrease yields; however, in northeastern Colorado, the concentrated high-salt runoff required dilution before direct application to crops. The organic manure-soil interface severely restricts the movement of water, nitrates, organic substances, and air into the soil beneath feedlots. Feedlots contribute NH3, amines, carbonyl sulfide, ~$2S, and other unidentified substances to the atmosphere. Anaerobic conditions in feedlots are conducive to the production of carbonyl sulfide, H2S, and amines. Management practices, such as good drainage, that enhance aeration will decrease the evolution of these compounds. PB-246 242/CCS NTIS Prices: PC$60.OO/MF$2.B5

DIRECT USE OF COAL IN A FUEL CELL: FEASIBILITY INVESTIGATION Stanford Research Inst., Menlo Park, Calif. National Environmental Research Center, Research Triangle Park, N. C. Control Systems Lab. Final Report 26 June 74 - 28 Feb 1975 Weaver, Robert D., Tietz, Laura, Cublcciotti, Daniel June 1975 64 pages ABSTRACT: The report gives results of the f i r s t phase of a study of the feaslbillty of using coal to produce electricity directly in a fuel cell that uses a moltencarbonate electrolyte, a coal anode, and an air cathode. The cell voltage, the polarization of the anode, and the nature of the gaseous products formed were investigated. Electrodes made from charred coal yielded opencircuit voltages close to l V. At 975 K, the activation plus concentration polarization was about 200 mV at current densities of lO0 mA per sq cm and larger. At higher temperatures smaller polarizations were observed. The gaseous anode products were primarily C02, with some CO. Current efflciencies were possibly due to losses of anode gases by mechanical means. Coal ash added to the molten electrolyte did not appear to be deleterious to cell operation. Descriptions of possible future engineering systems and thermodynamic limitations are presented.

Final Report See, G.G., Bode, C.A., Kacholia,K.K. October 1975 If6 pages ABSTRACT: The development and preliminary characterization of an electrolytic technique for destruction of microorganisms in potable and waste water were successfully completed. The technique employs low level cyclic voltages at chemically inert electrodes to pass an alternating current through the process water. The program was directed toward (a) expanding the design of the electrochemical bioclde reactor, (b) determining the engineering parameters which affect process effectiveness and efficiency and establishing hypotheses for the microorganism k i l l mechanism(s),and (c) preparing recoIFmmndations for scaling the process to both United States Army Medical Research and Development Command(USAMRDC) and the National Aeronautics and Space Administration (NASA) requirements. The report describes the experimental hardware, the methodology and

microorganism k i l l results with three bacteria: Escherichia cell, Pseudomonas aeruglnosa and Klebsiella pneumoniae), two viruses (Polio ] and Coxsackl B), one yeast (Sacchare~ces cerevisiae), and the normal flora of microorganisms found in domestic raw settled sewage. A literature search was conducted on prior research and development efforts related to the electrolytic disinfection of water and waste water. AD-AOI8 176/CCS NTIS Prices: PC$5.50/MF$2.2S

National Science Foundation, Washington, D.C. Office of National Centers and Facilities Operations. Technical Note Martell, Edward A. fiay 1975 54 pages Sponsored by National Science Foundation, Washington, D. C. Office of National Centers and Facilities Operations. ABSTRACT: Environmental transport of plutonium (Pu) is governed i n i t i a l l y by the physical and chemical properties of liquid and air effluents and subsequently by the modification of these properties in terrestrial and marine environments. Public exposure to Pu.will result from the i~halation of particulate plutonium dioxide and from Pu uptake via the food chain. An assessment of inhalation exposure is particularly dependent on the size distribution of Pu02 in airborne effluents, the air reentrainment of deposited Pu02 by natural processes, and the recycling of Pu02 by human and vehicular activity. Uptake of actinides via the food chain will result, from a complex array of environmental processes. Present knowledge and some of the more pertinent available literature bearing on these processes are reviewed. PB-245 727/CCS NTIS Prices: PC$4.50/MF$2.25

A CRITICAL EVALUATIONOF CURRENT RESEARCH REGARDINGHEALTHCRITERIA FOR SULFUROXIDES Tabershaw/Cooper Associates, Inc., Rockville, Md. Federal Energy Administration, Washington, D.C. Office of Energy Conservation and Environment. Technical Report Utidjian, H.M.D., Gaffey, W.R., Husting, E.L., Tabershaw, L.R~ April II 1975 128 pages ABSTRACT: The report is concerned with the scientific and technical bases for the ambient air quality standards for sulfur dioxide (SO2) and its derivatives, j o i n t l y designated 'Sulfur Oxides' (SOx) in community atmospheres. I t evaluates the evidence bearing on SOx and separates I t from t h e overall measurements and health effects of community air pollution. The rationale for examining S02 as an air pollutant is the fact that

191

combined sulfur in varying amounts is present in all fossil fuels. Oil, coal, and shale, when burned as energy sources, release sulfur oxides into the air and hence, the AAQS for S02 becomes a crucial determinant of the acceptability of such fuels. This report considers the ability of the body to absorb the toxicant in relation to functional and metabolic factors and defense mechanisms which negate, enhance or modify the effect. Analysis includes animal and human toxicology and evaluation of evidence for SO2 as a cause of death. PB-245 651/CCS NTIS Prices: PC$6.00/MF$2.25
