Geothermal waste treatment biotechnology: Progress and advantages to the utilities

Description: Development of biotechnology for treatment of geothermal residual waste is aimed at the application of low-cost biochemical processes for the surface treatment and disposal of residual geothermal sludges. These processes, in addition to the lowering of disposal cost, are designed to be environmentally acceptable. Recent studies at Brookhaven National Laboratory (BNL) have shown that optimization of several process variables results in fast rates (<24h) of metal removal from residual sludges at … more

H-Area Seepage Basins

Description: During the third quarter of 1990 the wells which make up the H-Area Seepage Basins (H-HWMF) monitoring network were sampled. Laboratory analyses were performed to measure levels of hazardous constituents, indicator parameters, tritium, nonvolatile beta, and gross alpha. A Gas Chromatograph Mass Spectrometer (GCMS) scan was performed on all wells sampled to determine any hazardous organic constituents present in the groundwater. The primary contaminants observed at wells monitoring the H-Area Se… more

Trace elements in the terrestrial environment of a coal-fired powerhouse

Description: A coal-fired powerhouse at the Savannah River Plant, Aiken, South Carolina operated for more than 20 years without electrostatic precipitators and consumed about 360,000,000 kilograms of coal per year. Twenty-nine trace elements were measured in fly ash, and in samples of soil, vegetation, and ground water collected along a 29-km traverse centered on the powerhouse. There were statistically significant effects of the stack releases upon the concentration of Ba, Be, Cu, Hg, Mn, Se, and Sr in soi… more

Mercury-binding proteins of Mytilus edulis

Description: Mytilus edulis possesses low molecular weight, mercury-binding proteins. The predominant protein isolated from gill tissue is enriched in cysteinyl residues (8%) and possesses an amino acid composition similar to cadmium-binding proteins of mussels and oysters. Continuous exposure of mussels to 5 ..mu..g/l mercury results in spillover of mercury from these proteins to high molecular weight proteins. Antibodies to these proteins have been isolated, and development of immunoassays is presently un… more

Geochemistry and hydrothermal alteration at selected Utah hot springs. Final report: Volume 3 (revised)

Description: Application of Na-K-Ca geothermometry to warm springs in Utah indicates several areas with sufficiently high apparent temperatures to be of interest as geothermal exploration targets. A zone of warm springs in the Bonneville Basin show Na-K-Ca temperatures from 150/sup 0/C to 233/sup 0/C. Examination of Great Salt Lake, Bonneville sediment pore water, and Jordan Valley well-water chemistry indicates that mixing a small percent of these fluids with warm spring water can cause substantial errors … more

Health and environmental effects document on geothermal energy: 1981

Description: Several of the important health and environmental risks associated with a reference geothermal industry that produces 21,000 MW/sub e/ for 30 y (equivalent to 20 x 10/sup 18/ J) are assessed. The analyses of health effects focus on the risks associated with exposure to hydrogen sulfide, particulate sulfate, benzene, mercury, and radon in air and arsenic in water. Results indicate that emissions of hydrogen sulfide are likely to cause odor-related problems in geothermal resources areas, assuming… more

Analysis of mercury diffusion pumps

Description: Several mercury diffusion pump stages in the Tritium Purification process at the Savannah River Site (SRS) have been removed from service for scheduled preventive maintenance. These stages have been examined to determine if failure has occurred. Evidence of fatigue around the flange portion of the pump has been seen. In addition, erosion and cavitation inside the throat of the venturi tube and corrosion on the other surface of the venturi tube has been observed. Several measures are being exami… more

Benefit-cost framework for analysis of trace element emissions from coal-fired power plants. [103 references]

Description: The major conclusions of this report may be summarized in the following four points: (1) It is probable that atmospheric emissions of trace elements from Southwestern coal-fired power plants will not cause major problems over the next 20 years. But monitoring for trace element build-up (especially mercury, selenium, and arsenic) in the mountains of southern Colorado, Navajo Reservoir, and other local hot spots would be an important and desirable step. (2) It appears that damage from trace eleme… more

Biological fate of cobalt-60 released during the corrosion of neutron-activated stanless steel in seawater

Description: Passing seawater over radioactive Type 347 stainless steel in a sediment/seawater laboratory system and exposing marine animals to this environment provided information on the bioaccumulation of /sup 60/Co from radioactive structural material. Exposure of marine organisms to radioactive corrosion products and directly to radioactive stainless steel in seawater simulated some of the possible conditions which could arise from the deposition of radioactive stainless steel on the ocean floor.

Distribution of mercury in the environment at Almaden, Spain

Description: An ecological survey of the concentration and distribution of mercury in terrestrial and aquatic systems near the mercury mine at Almaden, Spain, was initiated in 1974. Field studies were completed in 1977, and chemical analyses were completed in 1979. Sample collection at Almaden followed a trophic-level approach in which certain compartments were sampled at a given instant in time (fall 1974, fall 1975, spring 1976, fall 1976, spring 1977). Mean total mercury concentration in terrestrial plan… more

Trace-element geochemistry of coal resource development related to environmental quality and health

Description: This report assesses for decision makers and those involved in coal resource development the environmental and health impacts of trace-element effects arising from significant increases in the use of coal, unless unusual precautions are invoked. Increasing demands for energy and the pressing need for decreased dependence of the United States on imported oil require greater use of coal to meet the nation's energy needs during the next decade. If coal production and consumption are increased at a… more

Soft-sphere model for liquid metals

Description: A semi-empirical soft-sphere model of fluids is modified for application to the thermodynamic properties of liquid metals. Enthalpy, volume, and sound speed are computed as functions of temperature for 13 metals and compared with experimental data. Critical points and coexistence curves are also computed and compared with experimental data, where these have been measured. Strengths and weaknesses of the model are discussed.

Determination of low-level mercury by cold vapor generation and atomic absorption spectroscopy

Description: A procedure for determining mercury in liquid samples by cold vapor flameless atomic absorption spectroscopy was developed. The optimum parameter values were determined and mercury standard storage conditions investigated. The effect and tolerance levels of twenty-seven ions, including those ions common to Tank Farm Operations and the Synthetic Wastes, were measured. Standard deviation for the procedure is less than 1%. The procedure can be used to determine mercury at the part per billion leve… more
