Analysis of sediments and soils for chemical contamination for the design of US Navy homeport facility at East Waterway of Everett Harbor, Washington. Final report. [Macoma inquinata; Mytilus edulis]

Contaminated sediments in the East Waterway of Everett Harbor, Washington, are extremely localized; they consist of a layer of organically-rich, fine sediments overlying a relatively cleaner, more sandy native material. The contaminated layer varies in thickness throughout the waterway from as much as 2 meters to only a few centimeters. Generally, the layer is thicker and more contaminated at the head of the waterway (northern end) and becomes thinner and less contaminated as one proceeds south… more

Quantitative mammalian cell mutagenesis and mutagen screening: study with CHO cells

The CHO/HGPRT system has been developed and defined for quantifying mutation induced by various physical and chemical agents at the hypoxanthine-guanine phosphoribosyl transferase (HGPRT) locus in Chinese hamster ovary (CHO) cells. In all direct-acting chemical mutagens studied, mutation induction increases linearly as a function of the concentration, with no apparent threshold. Some chemicals induce mutation at non-cytotoxic concentrations. The mutagenicity of ethyl methanesulfonate has been q… more

Ground-water surveillance at the Hanford Site for CY 1982

Operations at the Hanford Site since 1944 have resulted in the discharge of large volumes of process cooling water and other waste waters to the ground. These effluents, which have reached the unconfined ground water, contain low levels of radioactive and chemical substances. The movement of these constituents in the unconfined ground water is monitored as part of the Ground-Water Surveillance Program. During 1982, 324 monitoring wells were sampled at various times for radioactive and chemical … more

Separations areas effluent treatment: The preparation of a simulated effluent for system development and testing

A fundamental parameter in the design of the Effluent Treatment Facility (ETF), the effluent composition, has recently been investigated by analyzing samples from both separations areas. As a result of this characterization program, we can now project the composition of the ETF feed stream. The anticipated feed composition is presented here for the purpose of making system projections; and a formula is provided for a simulant to use in testing evaporation, filtration, and reverse osmosis (RO) e… more

Microwave-assisted chemical process for treatment of hazardous waste: Annual report

Microwave energy provides rapid in situ uniform heating and can be used to initiate chemical processes at moderate temperatures. We investigate the technical feasibility of microwave-assisted chemical processes for detoxification of liquid hazardous waste. Trichloroethylene, a major constituent of waste streams, was selected for this detoxification study. Experiments were performed to investigate the oxidative degradation of trichloroethylene over active carbons (with and without catalysts) in … more

Electrochemical processing of nitrate waste solutions

Nitrate and nitrite have been almost completely removed from the synthetic effluent steam with good efficiency by affecting a separation across a pair of ion exchange membranes. In addition to recovering acid and base in this process, the volume of the remaining effluent is reduced considerably by transport of water across the membrane. One of the problems that remains with this process, however, is the stability of the membranes and particularly the stability of the anion exchange membrane. Th… more

Hanford Site ground-water monitoring for April through June 1987

Pacific Northwest Laboratory (PNL) is conducting ground-water monitoring at the Hanford Site. Results for monitoring by PNL and Westinghouse Hanford Company (WHC) during April-June 1987 show that certain regulated hazardous materials and radionuclides exist in Hanford Site ground waters. The presence of regulated constituents in the ground water derives both from site operations and from natural sources. The major contamination problems defined by recent monitoring activities are carbon tetrach… more

Effect on air and water emissions of energy conservation in industry

Environmental emissions for five large energy-consuming industries plus others are estimated for four US energy system scenarios for 1985 and 2000. Emissions are estimated by specifying fuel mixes to steam boilers and direct heat, combustion efficiencies, shifts in the relative shares of alternative industrial processes use of industrial cogenerators, and penetration of pollution-control technologies. Analyses show that emissions do not vary significantly among scenarios principally because of … more

Delisting petition for 300-M saltstone (treated F006 sludge) from the 300-M liquid effluent treatment facility

This petition seeks exclusion for stabilized and solidified sludge material generated by treatment of wastewater from the 300-M aluminum forming and metal finishing processes. The waste contains both hazardous and radioactive components and is classified as a mixed waste. The objective of this petition is to demonstrate that the stabilized sludge material (saltstone), when properly disposed, will not exceed the health-based standards for the hazardous constituents. This petition contains sampli… more

Repair of radiation damage in mammalian cells: its relevance to environmental effects

Assessment of the potential biological hazards associated with energy production technologies involves the quantitation of risk on the basis of dose-effect dependencies, from which, it is hoped, some safety guidelines can be developed. Our current knowledge of the biological importance of damage/repair processes stems by and large from radiation studies which clearly demonstrate that cellular response to radiation depends upon the ability of cells to repair the damage. Apparently, the same is t… more

Dispersion calculations for non-radiological hazardous chemical emissions from the Defense Waste Processing Facility and related activities

The Environmental Protection Agency's (EPA) Industrial Source Complex -- Short Term (ISCST) air dispersion model was used to examine potential atmospheric impacts of routine benzene and mercury emissions from the Defense Waste Processing Facility (DWPF), In-Tank Precipitation (ITP) facilities, and the Saltstone Facility. The highest model estimated 8-hour average ground-level benzene concentrations were found to occur in the immediate vicinity of the ITP filter/stripper building (241-96H). Subs… more

Environmental control technology survey of selected US strip mining sites. Volume 2A: Ohio: water quality impacts and overburden chemistry of Ohio study site

An intensive study of water, overburden, and coal chemistry was conducted at a large surface mine in Ohio from May 1976 through July 1977. Sampling sites were chosen to include the final mine effluent at the outflow of a large settling pond and chemically-treated drainage from a coal storage pile. Samples were collected semimonthly and analyzed for total dissolved solids, total suspended solids, alkalinity, acidity, sulfate, chloride, and 16 metals. Field measurements included pH, flow rate, di… more

Marine mammal fauna of potential OTEC sites in the Gulf of Mexico and Hawaii

Twenty-seven marine mammal species have been recorded for the Gulf of Mexico, including 7 Mysticetes or baleen whales, 17 Odontocetes or toothed whales, 1 Sirenian (manatee), and 1 or 2 Pinnipeds or seals. The most common species in the Gulf is the bottlenosed dolphin, an inshore species. Offshore, the spotted dolphin, is fairly common. Most other species are recorded from very few sightings or strandings. None of the endangered species is common in potential OTEC sites in the Gulf of Mexico. T… more

This evaluation provides estimates of performance and cost data for advanced technology, high-Btu, coal gasification facilities. The six processes discussed reflect the current state-of-the-art development. Because no large commercial gasification plants have yet been built in the United States, the information presented here is based only on pilot-plant experience. Performance characteristics that were investigated include unit efficiencies, product output, and pollution aspects. Total install… more

Man's effect on stratospheric ozone

Since McDonald, at the beginning of this decade, first proposed that water vapor from SST exhaust would lead to increases in skin cancer, about a dozen man-induced mechanisms have been suggested as threatening to modify our stratospheric ozone uv-shield. Possible thinning of the ozone layer has been attributed to one or more of the catalytic ozone destroyers, water vapor (HO/sub x/), oxides of nitrogen (NO/sub x/), chlorine (ClX); or bromine (BrX). The original catalyst, HO/sub x/, rather quick… more
