RISK ASSESSMENTS 115 111 ------- IV ------- INTRODUCTION Environmental statistics is a complex subject that cuts across many disciplines and organizations. It is a crucial aid to designing and evaluating verifiable data collection systems and to making valid conclusions for appropriate regulatory response. Likewise, it is essential to determining the need for enforcement action, once those regulations are in place. Basically, it does that by providing a consistent mechanism for interpreting data and for making correct inferences from samples. This bibliography has pulled together citations from a wide range of recent documents and includes references that may be of particular interest to the statistical community and of general interest to environmentalists.

Sci., 113, Language: English Document Type: Proceedings Paper Subfile: MR (Mathematical Reviews) AMS Abstract Length: MEDIUM (16 lines) Summary: Regarding an ecological network as a communication channel, the information contained in the structure of an ecological network may be theoretically defined by the concept of mutual information. Optimal aggregation minimizes the difference of mutual information between object system and aggregated model. The information cannot increase (it generally decreases) during the process of network aggregation. First, we study what kind of patterns of structure of ecological networks result in no aggregation loss. Parallel structures are shown as special patterns of structure which result .in no loss of information. Parallel structures generally tend to minimize aggregation loss. Second, we show how grouping compartments so as to minimize the loss of mutual information creates collections of species, i.e., how aggregation identifies the macro- structure (e.g.\ hierarchical structure) of ecological networks. Approximate aggregation is applied to several real ecological networks."

B - SCI. & ENG VOL 49, NO. 9, Publ.Yr: 1989 SUMMARY LANGUAGE - ENGLISH; Diss. Ph.D. Order No.: DA8826376. Languages: ENGLISH This research compares three policy alternatives/institutions for managing environmental problems, discusses the reward systems inherent in each system and evaluates the relative efficiency of outcomes under the different alternatives using a timber harvesting/fish habitat case study and a mathematical model. Several policy options are available to resolve environmental conflicts. Regulations, common in the United States, are generally inefficient. Regulations fail to provide incentives to individuals to provide socially desirable resources, particularly those of a "public good" nature. Regulations offer incentives to transfer wealth between client groups rather than provide environmental benefits.

Two general approaches are outlined, based: on classic statistical methods and on Bayesian statistical methods. Their advantages and disadvantages are discussed in relation to the overall decision-making process. The article concludes by presenting an application of the Bayesian approach to the body of bioassay data available at the time of the regulatory decision concerning the link between saccharin and bladder cancer.

ENVIRON VOL 22, NO. 9, pp. 1957-1962, Publ.Yr: 1988 SUMMARY LANGUAGE- ENGLISH Languages: ENGLISH Simulated "empirical" data sets were generated to assess the effect of a normally distributed blank on the apparent frequency distribution of a constituent whose concentrations are actually lognormally distributed. When the standard deviation of the blank (s sub(blank)) is relatively small, on the order of 10-50% of the geometric mean, the major consequence is a significant downturn in the cumulative probability plot at the low end of the concentration scale. With larger standard deviations, the upper portion of the plot is also substantially affected; concentrations for a given cumulative frequency can be significantly higher than those which actually exist. Regression of the data above the detection limit (defined as 2 times s sub(blank)) can yield reasonably good estimates of the actual distribution parameters even when the standard deviation is comparable to the actual geometric mean. At higher standard deviations, regression analysis yields substantially biased results.

Date: Dec 87 Pages: 60p NTIS Price Code: PC A04/MF A01 Language: German Abstract: Mathematical models which consider the most relevant environmental transport and transformation processes, were developed for the description of the environmental fate of chemicals. Three models regarding the behaviour in soil (EXSOL), surface waters (EXWAT) and lower troposphere (EXAIR) together with another model (EXINT) which describes the exchange processes between these three media form the core of a system for exposure estimations. Two further models are available for special situations. For estimating ecotoxicological effects, use is made from toxicological single-species-tests (ETTOX). The release from the technosphere into the three media soil, water and air is determined from the production volume and the use pattern (RLTEC). Environmental hazard potentials are derived from release, fate and effect potentials, and applied to priority setting among existing chemicals. For this purpose, the models and the decision aids are combined in a computer program E4CHEM (Exposure and Ecotoxicity Estimation for Environmental CHEMicals). By means of E4CHEM, descriptors of the environmental hazard are calculated from substance data with predetermined environmental conditions. The descriptors are defined with the aim to correspond with the selection criteria of the German Chemicals Act. The final results of the calculations are lists of chemicals in the order of increasing hazard.

Super. Sant., Viale Regina Elena 299, 00161 Rome, Italy STAT. MED VOL f, NO. 2, pp. 201-206, Publ.Yr: 1989 SUMMARY LANGUAGE- ENGLISH Languages: ENGLISH Measures of chronic degenerative disease diffusion, such as incidence and prevalence rates, are a basic need for epidemiologists and others working in many fields of human sciences. Equations relating death probabilities to incidence and survival probabilities for chronic degenerative diseases are derived from a cohort point of view. A maximum likelihood approach is adopted for the estimation of incidence as a function of time related covariates. When time series of mortality data are available, the model can be used to describe and analyse levels and dynamics of morbidity. A trial application to lung and breast cancer is given for the province of Varese, Italy, where incidence data are available from the Lombardy Cancer Register.

Crucial information necessary to design such an accelerator is acquired by running the ROM computer code under instrumentation which shows how the computational load is distributed within the model and the data transfer rates between each step of the model execution. These data reveal that a model such as the ROM is not amenable to acceleration using a vector-type architecture because the computational burden is too inhomogeneous in space and time. Simulations show that an accelerator based on the tile machine architecture would be capable of executing the ROM up to 100 times faster than the host machine working alone.

Res., Private Bag No. 1, PO Mordialloc, Vic. 3195, Australia BOUNDARY-LAYER METEOROL VOL. 38, NO. 3, pp. 209-223, Publ.Yr: 1987 SUMMARY LANGUAGE- ENGLISH Languages: ENGLISH A set of concentration time series from ground-level plumes in the atmosphere has been used to generate conditionally sampled (zeros ignored) plume concentration statistics. These have been compared and contrasted with corresponding unconditionally sampled statistics. It is found that conditional statistics are much less sensitive to the location of the receptor (relative to the mean plume) and to averaging time. Indeed, most of the variation apparent in unconditionally sampled statistics (both explained and unexplained) resides in the intermittency, the fraction of non-zero readings. The data are used to test three commonly used models for the concentration frequency distribution. At the simplest level of modelling, it is assumed that conditional statistics are invariant; then the data are best represented by a clipped-normal distribution. However, an exponential distribution is only slightly conservative and has the advantage of simplicity. A log-normal distribution is clearly not supported by the data. With this simple approach the intermittency remains unspecified and this is a serious deficiency. [PA] NTIS No: PB88-202387/HDM Title: Dispersion Model for Elevated Dense Gas Jet Chemical Releases.

The Ooms model describes the release and subsequent dilution and trajectory of an elevated gas jet as a gas plume. If the plume falls to ground level, DEGADIS describes the resulting ground-level plume. DEGADIS can also be used to describe the release and dilution from a low-momentum, ground- level release. The necessary model-input information to simulate a denser-than-air gas release is summarized.

ISSN: 0097-4943 CODEN: CMAPDK Language: English Document Type: Journal Subfile: MR (Mathematical Reviews) AMS Abstract Length: MEDIUM (13 lines) Summary: A study of air pollution phenomena over a large space domain by a fairly general mathematical model is discussed. The space discretization of a model leads to huge systems of ODEs. The integration algorithms used in the solution of these systems must be efficient. If a 3D model is considered, then a vector processor is to be used. Moreover, the most time-consuming parts of the code are to be vectorized. The calculated results, concentrations of different air pollutants, must be reliable, because they have to be used by other specialists. Therefore different checks concerning the reliability of the results are carried out. In this paper it is shown that an efficient and reliable code for studying both sulphur and nitrogen pollution has been developed. Some simulation processes are also described briefly."

The same unsubstituted PAH have been determined in air samples collected near an aluminum reduction plant. Analysis by high-resolution gas chromatography-mass 18 ------- spectroscopy in the selected' ion mode showed concentrations in soil ranging from less than 1 ppb (detection limit) to 993 ppb for individual unsubstituted PAH. The highest concentrations are found close to aluminum plants. Correlation analysis and SIMCA pattern recognition show that the patterns of unsubstituted PAH in soil samples collected close to aluminum plants are different from those in soil samples collected from other areas. Soil samples from a bog environment show a somewhat different pattern of PAH than other soil samples. (Author abstract) 43 refs.

Specifically, the purpose of the study was to determine whether ground-water quality variables: (1) are normally distributed, (2) exhibit seasonal patterns, and (3) are correlated in time. The results of the investigation suggest that many ground-water quality variables: are not normally distributed, but have skewed right distributions; can exhibit seasonal fluctuations of various shapes and magnitudes, especially in shallow or highly permeable aquifers; and can exhibit significant serial correlation when samples are collected quarterly.

Date: 15 Dec 87 Pages: 18p NTIS Price Code: PC A03/MF A01 Language: English Abstract: The capability of the three-dimensional MATHEW-ADPIC atmospheric transport and diffusion models to simulate pollutant dispersion in a coastal, environment was evaluated by utilizing data from a series of meteorological and tracer experiments conducted across the Oeresund strait between Denmark and Sweden. These experiments, which were designed to study atmospheric dispersion processes associated with flows over cold water and warm land surfaces, included the release of a tracer from the upwind coastline. This tracer was transported over the Oeresund strait and subsequently sampled along the downwind coastline. The results of the comparisons between the simulated and the measured tracer concentrations reveal that in general the calculated maximum concentrations are higher than those measured by factors of up to 4. A statistical analysis of the individual sample comparisons indicated that approximately 50% of the comparisons are within a factor of 4. This overprediction is believed to be due to the development of a shallow stable layer over the cold water surface. 17 refs., 11 figs., 1 tab.

The objective is to identify sources of air pollution, to estimate the variation of total suspended particles (TSP) for the different sources and to calculate the annual average source contribution to TSP. The basis for analysis is the chemical mass balance equations. Factor analysis methods are used to identify major sources of pollution and the contribution from each of the sources to the variation in TSP is estimated by an additional multiple regression. Finally, the influence of serial correlations between daily element contributions is discussed and it is stressed that the result of the analysis is not seriously affected by these correlations.

Date: Apr 88 Pages: 60p NTIS Price Code: PC A04/MF A01 Language: English Abstract: The report describes the development of a model for predicting industrial firms' choices of boiler fuel for production of process steam. In contrast to fuel choice models currently in operation, the model described here predicts fuel choices probabilistically, rather than 26 ------- deterministically. In addition, the model is empirical, does not assume that the costs relevant to fuel choices necessarily are best summarized by a single, total annualized cost, and provides a way to represent the effects of non-cost factors that may influence industrial boiler fuel choice decisions. These characteristics enable the model to provide a considerably more accurate description of fuel choices than do deterministic models that assume these choices to be based only on considerations of total annualized costs. The work was instrumental in developing a clearer understanding of the relative importance of the factors at work that have major influence on the industrial boiler fuel choice decision.

For a series of experimental explosibility tests approximated by combustion zones that expand at a constant flame velocity, the mass fraction of airborne rock dust ahead of the flame front, as well as the mass fraction overtaken by the combustion zone, was calculated, A statistical analysis of ;the theoretical results demonstrated .with a high level of confidence that the propagating and nonpropagating test samples belonged to separate populations. This analysis was further supported by an independent model of the averagae temperature over the combustion zone. (Author abstract) 25 Refs.

In recent reports . on the analysis of data sets with known structure/good results were obtained. In order to further test the TTFA approach, additional simulated data sets have been created with varying degrees of collinearity of the source profiles and normally distributed uncertainty. The effect of the collinearity is to restrict the number of resolvable sources. The analytical error affects the identification of the number of sources and development of accurate profiles.

Although scrubbers reduce acid gas emissions, it has never been demonstrated that such reductions are needed to protect health. The authors believe that the EPA's analysis leads to the incorrect conclusion that scrubbers are necessary on new incinerators. They present an alternative assessment. The authors believe that the most 39 ------- likely technology-by-technology emission factors, and the geometric mean or average of any other correction factors applied should be employed to assess relative nationwide annual cancer risks. When appropriate statistical analysis of the emissions data is used, a wholly different risk picture emerges than that presented by the EPA. The authors recommend that the EPA focus on strategies to phase out the older, high- emitting facilities, if they feel that some regulatory strategy is needed. Srefs.

To illuminate the relationship between visibility and meteorology, we present, in this technical note, a simple statistical analysis of visual range measurements in urban and rural areas of the eastern United States under different meteorological conditions. The eastern United States was divided into four areas. Eight subregions were produced when the four areas above were subdivided into urban and rural sections. Visibility data collected at airports were used. Days with high relative humidity are characterized by the lowest visual range. The 'continental' meteorological regimes are associated with higher visual ranges, while 'maritime' conditions have lower visual range. Coastal regions generally have higher visual ranges than central regions. 10 Refs.

The treatments were established by adding O3 in amounts that were proportional to ambient O3 concentrations or in constant amounts. The frequency of occurrence and level of peak O3 concentrations were greater for each proportional- addition treatment than for the corresponding constant-addition treatments. However, the seasonal mean O3 concentrations were nearly identical, and the yield response to O3 was similar for both types of O3 for 12 hr/day (1000 to 2200 hours EOT) was 10% less (three treatment levels combined) than in those receiving proportional addition for 7 hr/day (1000 to 1700 hours EDT). If other important crop species have a similar response to 03 late in the afternoon, previous national crop loss estimates based on seasonal 7 hr/day O3 exposures may be low.

Because of the high data density, dependable conclusions with respect to trends and mass balances may be drawn. It could be shown that in the past years the oxygen concentration has increased and the loads of organic carbon and anionic and non-ionic surfactants have decreased. Of the inorganic parameters, chloride and borate are stagnant while phosphate has decreased considerably. Altogether water quality has improved to an essential extent. (Author abstract) 38 Refs.

Specific mortality predictors included cigarette smoking, drinking water hardness, heating fuel use, and 1978-1982 annual concentrations of the following air pollutants: ozone, carbon monoxide, sulfate aerosol, particulate concentrations of lead, iron, cadmium, manganese, vanadium, as well as total and fine particle mass concentrations from the inhalable particulate network (dichotomous samplers). In addition, estimates of sulfur dioxide, oxides of nitrogen, and sulfate aerosol were made for each city using the ASTRAP long-range transport diffusion model, and entered into the analysis as independent variables. Because the number of cities with valid air quality and water hardness data varied considerably by pollutant, it was necessary to consider several different data sets, ranging from 48 to 952 cities. The relatively strong associations (ca. 5- 10%) shown for 1980 pollution with 1980 total mortality are generally not confirmed by independent studies, for example, in Europe. In addition, the US studies did not find those pollutants with known adverse health effects at the concentrations in question (such as ozone or CO) to be associated with mortality. The question of causality vs. circumstantial association must therefore be regarded as still unresolved. 59 refs., 20 figs., 40 tabs. (ERA citation 13:041161) [NT] 47 ------- II E.

Cluster analysis, based on the pattern of presence and absence of chemicals, was able to separate locations within and between the two types of building. The ten most critical chemicals in this respect were subjected to more complete statistical analysis in order to highlight further possible differences between the buildings.

Fluxes, along with other turbulence statistics, are computed in real- time and printed at end of each averaging period. The main elements of the program are (1) "detrending" (by use of running mean removal), (2) calculation of the entire stress tensor (which allows a three-dimensional coordinate rotation to be performed on the covariance), (3) software- adjustable timing delays for each instrument channel, and (4) real-time graphic presentation of the raw data as stripchart images, the first two of these program elements tend to relax the normal site and sensor-leveling requirements. Sample results are presented, and the -sensitivities of the calculated quantities to coordinate rotation and to mean removal time are examined for both ideal and non-ideal sites. [PA] 02298353 E.I.

Algebraic expressions for the modification of air velocity variance sigma super(2) and Lagrangian autocorrelation time-scale T sub(L), due to particle inertia effects, are derived. These expressions introduce only a very small computational overhead on the random-walk models for inertia-less particles of Wilson et al. (1983). Measurements of T sub(L) and sigma by Snyder and Lumley (1971) for four different particles are used to determine constants in the heavy- particle model. It is shown that the agreement between the model, for a single set of constants, and the dispersion measurements is good for the 47 mu m hollow glass, 87 mu m glass, and 47 mu m copper particles. The predictions 53 ------- for the 87 mu m corn pollen particles show less satisfactory agreement by underestimating dispersion measurements by 15% after 0.4 s.

The simulation is based on a large set of total phosphorus data from the Potomac River. To assure that the simulated records have realistic 54 ------- properties, the data are modeled in a multiplicative fashion incorporating flow, hysteresis, seasonal, and noise components.

The predominate type of damage and the function of the barrier are dominant type of damage and the function of the barrier are found to depend on the initial moisture conditions of the subsoil. For desiccated soils, the barrier must prevent the infiltration of rainfall into the shrinkage cracks to stop the development of roughness. For wet soils, the barrier must prevent excessive drying under the edge of the pavement. The barrier depth is chosen base on the maximum crack depth and the shrinkage of the pavement edge that would occur under the most severe drought intensity expected during the lifetime of the pavement. The drought intensity is chosen based on a 57 ------- statistical analysis of meteorological data for the site. (Edited author abstract). 30 Refs.

Sediment rates always showed the same relative- five-fold difference at a primary site within each estuarjne area. Samples from 11 ancillary sites indicated biodegradation rates in sediments can be subdivided into two groupings which were independent of seasonal differences (excluding temperature). Spatial variations in rates, therefore, may be of minor environmental significance for the chemical in estuarine areas.

The system uses 60 ------- knowledge and inference rules obtained from hydrodynamic experts to classify and predict buoyant jet mixing. CORMIX1 gathers the necessary data, checks for data consistency, assembles and executes the appropriate hydrodynamic simulation models, interprets the results of the simulation in terms of the legal requirements including toxic discharge criteria, and suggests design alternatives to improve dilution characteristics. The results of the hydrodynamic simulation are in good to excellent agreement with field and laboratory data. In particular, CQRMIX1 correctly predicts highly complex discharge situations involving boundary interactions and buoyant intrusions, a result not predicted by other currently available initial mixing models.

This article focuses on the information needs of water quality management and how these needs are best met for monitoring systems that require many trace-level measurements. It proposes that the limit of detection (LOD) or the limit of quantitation (LOQ) not be used to censor data. Although LOD and LOQ aid in the interpretation of individual measurements, they hinder statistical analysis of water quality data. More information is gained when a numerical result and an estimate of measurement precision are reported for every measurement, as opposed to reporting 'not detected1 or 'less than'. Subjects covered include statistical analyses, monitoring information, and system error. 42 Refs.

To run these models, a variety of input data on receiving water-body properties arid water-quality parameters that define a range of environments and influence the chemical-specific rate coefficients must be developed. A data base that contains selected hydrologic and water quality parameters has been developed by EPA for 15 major U.S. river basins. .Galled the Canonical Environments Data Base, the file brings together information developed by public and private organizations on each reach of the rivers as well as individual lakes and reservoirs in the basins. Coupling raw data with a data base management system in the environmental file will facilitate entry into and deletions from the data base and development of data input to the Exposure Analysis Modeling System (EXAMS) and other similar exposure assessment mathematical models.

Date: Dec 88 Pages: 36p NTIS Price Code: PC A03/MF A01 Language: English Abstract: The study illustrates the use of indicator geostatistics for interpreting complex alluvial stratigraphy from qualitative borehole logs. Locations of relatively high and low permeability regions are described by inferring relative permeability from borehole descriptions and assigning binary indicator values of either 1 or 0 to intervals in the borehole logs. The resulting indicator data can then be used to compute experimental variograms and construct three-dimensional variogram models. The 64 ------- approach is applied to a groundwater contamination site in Santa Clara Valley, CA. Computed indicator variograms are consistent with known stratigraphic features. They describe details in the spatial structure of the deposits that reflect differing depositional environments. Indicator kriging consistently weights all the available data on the basis of a three-dimensional, anisotropic variogram model and provides an estimate of uncertainty in the hydrostratigraphic correlation.

The survey included three distinct parts: a Phase I survey of streams in the mid- Atlantic region; a Screening survey designed to assess the need for future Phase I studies in the United States; and an Episodes Pilot survey designed to provide a preliminary assessment of the frequency, duration, and characteristics of storm episodes in the mid-Atlantic states. The report describes the survey planning, protocol development, personnel requirements, field operations, and logistical aspects of all three components of the National Stream Survey. Because of the large scope and geographical area covered by the survey, sampling regions were subdivided into four areas, each containing approximately the same number of streams. Samples were collected, shipped at 4 degrees C, and received within 24 hours by a central processing laboratory. Sampling was completed on schedule, and 447 out of a total of 479 streams were sampled. A detailed evaluation of episodes sampling is provided with recommendations for future consideration.

An extensive quality assurance program has been established in support of the objective. To evaluate the effectiveness of the quality assurance program, several types of quality assurance and quality control samples were collected and analyzed during a pilot survey that was conducted prior to the initiation of National Stream Survey Phase I field activities. The report presents a statistical analysis of results obtained for field duplicate samples, blank samples, and audit samples used in the pilot survey. The results show that even overall estimated within-batch precision was adequate to meet the analytical data quality objectives established for the National Stream Survey and that detection limit goals were achieved at the contract analytical laboratories. The observed system decision limits and system detection limits, however, must be considered in interpreting the pilot study data and data from future surveys that employ similar sampling, processing, and analytical methods.

If a single detection limit is used for the entire study, existing nonparametric statistical methods, modified for ties, are applicable. If, however, the detection limit varies during the course of the study, resulting in multiple detection limits, then the commonly used trend detection methods are not appropriate. A statistic similar to Kendall's tau, but based on expected ranks, is proposed. Monte Carlo simulations show that the normal approximation to the distribution of this statistic is quite good, even for small samples and a large proportion of censored observations.

WASP4 simulates the transport and transformation of conventional and toxic pollutants in the water, column and benthos of 72 . ------- ponds, streams, lakes, reservoirs, rivers, estuaries, and coastal waters. The WASP4 modeling system covers four major subjects-hydrodynamics, conservative mass transport, eutrophication-dissolved oxygen kinetics, and toxic chemical-sediment dynamics. The WASP4 modeling system consists of two stand-alone computer programs, DYNHYD4 and WASP4, that can be run in conjunction or separately. The hydrodynamic program, DYNHYD4, simulates the movement of water and the water quality program, WASP4, simulates the movement and interaction of pollutants within the water. The latter program is supplied with two kinetic sub- models to simulate two of the major classes of water quality problems-- conventional pollution (dissolved oxygen, biochemical oxygen demand, nutrients, and eutrophication) and toxic pollution (organic chemicals, heavy metals, and sediment). The substitution of either sub-model constitutes the models EUTRO4 and TOXI4, respectively. [NT] 73 ------- 74 ------- Ill B.

QUAL VOL. 15, NO. 1, pp. 13-16, Publ.Yr: 1986 SUMMARY LANGUAGE- ENGLISH Languages: ENGLISH : Solid filtered or centrifuged potato processing wastes were obtained from three potato processors in Idaho. The waste samples were dried and ground to pass a 2-mm sieve and added to soils at rates of 0,2.5, 10, and 25 g/kg. The 100-g samples of Portneuf silt loam soil containing the waste material was incubated at. 26 degree C and decomposition of the added wastes was determined by measuring CO sub(2) evolution in a flowing air stream passing over the soil in the incubation flask. Each increment of added organic waste material increased the amount of J carbon evolved during the 12-week incubation. The waste materials contained 6.8, 20.4, or 65.5 g N/kg waste. However, these differences in N did not change the amount of CO sub(2) evolved at the 12-week incubation, although the evolution curves were shaped somewhat differently during the 12 weeks. Regression analyses of the cumulative carbon resulted in highly significant R super(2) values being obtained for each potato processing waste material. Decomposition of the solid waste materials ranged from 24 to 92% depending upon the source and application rate. The rapid decomposition of the solid wastes verified field research indicating that potato wastes have not more than 1 yr residual fertilizer value.

Present waste load allocations for toxicants generally rely on simple dilution calculations for low stream flow conditions. The paper examines the new water quality criteria for toxicants and the modeling strategies used to implement the criteria. The new criteria specify an acute threshold concentration and a chronic-no-eff~ct concentration for each toxicant as well as tolerable durations and frequencies of exposure at or above the two concentrations. Methods for using steady-state and dynamic models to derive waste load allocations based on the new criteria are reviewed. Physical/chemical, and biological processes affecting toxicants in the mixing zone .and far-field regimes of streams are summarized.

This measure is illustrated using data from a domestic sewage treatment plant. Pain/vise correlations were determined for violations of influent biochemical oxygen demand (BOD), suspended solids (SS), and average flow design limits. BOD and SS violations were positively correlated with each other and negatively correlated with flow violations. Similar results were obtained for effluent violations. Three-way correlations for both influent and effluent were significant and negative, suggesting that flow was a common causative factor for the noncompliance events in this plant.

This paper examines the potential for management of on-lot systems by a municipal or regional management agency. Such management, because more frequent inspection and pumping of on-lot systems would occur, promises reduced ground and surface water pollution and reduced potential for public health hazard. It can reduce the costs of inspections and pumping on a per system basis due to possible economics of scale and management efficiencies. This paper also estimates the annual fee required to support municipal septic management, with and without the assumption by the municipal agency of all repair, replacement, 81 ------- and rehabilitation costs for the systems under its management. These latter costs are estimated by combining a statistical analysis of failures and repairs over the past 36 years in Amherst, Massachusetts, and the reported costs for typical repair and replacement actions.

Desulfurization slag is formed by application of calcium carbide to hot metal for the purpose of sulfur removal from original concentrations in the range of 0.04% to acceptable concentration of 0*01%. The resulting slag contains excess of calcium carbide, some calcium oxide and sulfide, and iron oxides. The elemental composition of desulfurization slag is distinctly different from other metallurgical slags. Typically it contains 45-48% of iron, 10-15% of calcium and 1.5- 1;.6% of sulfur. The treatment effects of the desulfurization slag are based on a release of sulfide and hydroxide ions on its contact with water, and on sorption qualities of the iron oxide. A high concentration of iron in this slag indicates a possibility of its recycle to the blast furnace after sintering. Only a high sulfur contents in this material may affect adversely the attractiveness of the slag reuse. However, the same utilization of the slag may be considered also after its use for wastewater treatment. The wastewater treatment sludge can be dewatered, dried, sintered, and directed to the blast furnace. The recycled material will contain much less sulfur than the original slag.

Three phases of the project were identified: (1) to collect existing literature and data; (2) to select, develop, and test the utility of methods to quantify the relationships between land use, cover types, soils, hydrology, and water quality (as represented by sediment); and (3) to apply selected methodologies to several sites within the Yazoo Basin of Mississippi. Methods developed focused on linking a simulation of water and sediment movement to a computerized geographic information system. The authors had several objectives for the resulting model. The authors desired that it should estimate the importance of bottomland hardwoods as a cover type that performs the functions of erosion and sediment control.

Blue Mesa Reservoir was chosen for two reasons: (1) the impoundment is 20 years old, and should have attained trophic equilibrium; and (2) there is a relatively large amount of data with which to assess the impoundment's biological, chemical, and physical structure and function over time. The data were analyzed for historical trends. Evidence of such trends was interpreted and used to assess present reservoir trophy, to predict future reservoir trends, and to indicate future management possibilities.

As an application, WATERSHED is used to assess options to improve the quality of highly eutrophic Delavan Lake in Wisconsin. WATERSHED is flexible in that several techniques, such as the Universal Soil Loss Equation or unit-area loadings, can be used to estimate nonpoint-source inputs. Once the model parameters are determined (and calibrated, if possible), the spreadsheet features can be used to conduct a sensitivity analysis of management options. In the case of Delavan Lake, it was concluded that, although some nonpoint controls were cost-effective, the overall reduction in phosphorus would be insufficient to measurably improve water quality.

Lake selection involved a variable probability sampling design. Fish communities were surveyed using gill nets, trap nets, beach seines, and angling. Duplicate surveys were conducted for 10 of the 49 lakes as part of the quality assurance/quality control protocol. Fish were collected in 47 of the 49 lakes surveyed. Extrapolation of the results to the Eastern Lake Survey Phase II target population suggests that 99.4% of the lakes in the area support fish. For the 49 survey lakes, the number of fish species caught per lake (species 95 ------- richness) was lower in seepage lakes (without inlets or outlets) than in non-seepage lakes and was also lower in lakes with lower pH, ANC, calcium (and other base cations), DOC, and silica and with higher levels of extractable aluminum. In contrast to the large number of variables associated with fish presence/absence and species richness, variations in the numbers of fish caught and catch per unit effort among lakes appeared to be independent of lake characteristics.

GIS can be used to quantify rates of regional resource loss by comparing data layers representing different years. A cumulative impact evaluation method involving aerial photointerpretation, multivariate statistical analysis, and GIS techniques was developed and used to relate past and present wetland abundance with stream water quality in the Minneapolis-St. Paul metropolitan area. The results demonstrate the importance of wetland position in the watershed to water quality, a relationship which would have been difficult to detect without the benefit of GIS assisted analysis.

It was found that CH//2CI//2 remained stable in Tedlar bags for at least four weeks. The analytical method selected was gas chromatography with flame 102 ------- ionization detection (GC/FID); The range of concentrations from the sources was 100 ppm to 27,000 ppm CH//2CI//2. A statistical analysis of samples collected simultaneously showed no difference in the samples, proving good precision in both sampling and analysis. Some of the sample bags returned from the test sites developed leaks indicating that immediate on-site analysis is best. A comparison of results obtained in the field and the two laboratories showed that inter- and intra-laboratory precision was within 10 percent. (Edited author abstract) 8 refs.

Notes: Sponsored by Environmental Protection Agency, Cincinnati, OH. Risk Reduction Engineering Lab. Date: Jan 89 Pages: 26p NTIS Price Code: PC A03/MF A01 Language: English Abstract: The report summarizes the results of EPA's research program to evaluate the current performance of 25 commercially available volumetric test methods for the detection of small leaks in underground gasoline storage tanks. The leak rate measurable by these systems ranged from 0.26 to 6.78 L/h (0.97 to 1.79 gal/h) with a probability of detection at 95% and probability of false alarm of 5%. Five of the methods achieved a performance that was better than 0.57 L/h (0.15 gal/h). The measured performance was considerably poorer than the often claimed 0.19 L/h (0.05 gal/h). The performance of the methods evaluated here was limited by current protocol and practice rather than by hardware. Such limitations can be overcome by rather modest modifications to testing practice rather than by major system redesign.

Life table analysis of cancer bioassays is discussed. Current assumptions about the lethality of treatment and tumor can lead to incorrect interpretation of results. An introduction to the concepts of Bayesian statistics and how the application of judgmental probabilities can assist in reaching broad conclusions is presented. Bayesian methods to estimate the likelihood of bioassay outcomes given short-term test data are discussed. A Bayesian method is used to integrate data from different bioassays of the same substance.

Quantitations on the one hand are based on secondary data, i.e. the computation and workup of statistical data, on the other hand, on own analyses of houshold waste. Both quantitatibn ; schemes were put into relation and have been evaluated. Two potentials of harmful matters (heavy metals and halogenes) were computed from the results of chemical analyses of household waste and unused product samples together with the mass related data. With the workup of secondary data the origins of harmful matter concentrations are traced and their relevance to waste treatment techniques is briefly outlined. Alternative packaging materials are discussed by means of scenarios, to minimize the evironmental effects related to their production and disposal. (orig./RHM). (TIB: FR 1087+a.)

Date: C1988 Pages: 10p NTIS Price Code: PC A02/MF A01 Language: English Abstract: Results of the laboratory tests are used in assessing the environmental risk of exposure to industrial chemicals. The combined effects of dose-level exposure ana1 time-duration exposure are tested in the laboratory, but only a single endpoint reflecting the dose-level exposure at the end of the test period is routinely reported and used. At times, this might be sufficient, or the data otherwise inappropriate for calculation of more than a single endpoint. Nevertheless, an approach that makes a more complete use of existing sufficient test information is needed. One method is presented in the paper, the focus of which is the evaluation of an LC50 endpoint at a calculated exposure time. This calculation determines a condition for the toxicity curve to become established along the time axis. The authors refer to this condition of the dose-response curve as an asymptotic state and the LC50 calculated from it as the asymptotic LC50. An analysis of 152 toxicity tests using fathead minnows show that the 96-hr LC50 is 25% more conservative than the asymptotic LC50. The calculation of LC50 under asymptotic conditions better enables comparing toxicities of different chemicals on the basis of comparable dose-level and time-duration exposures.
