The Special Projects Section (SPS) of Reynolds Electrical & Engineering Co., Inc. (REECO) is responsible for characterizing the subsurface geology and hydrology of the Area 5 Radioactive Waste Management Site (RWMS) at the Nevada Test Site (NTS) for the US Department of Energy, Nevada Operations Office (DOE/NV), Environmental Restoration and Waste Management Division, Waste Operations Branch. The three Pilot Wells that comprise the Pilot Well Project are an important part of the Area 5 Site Characterization Program designed to determine the suitability of the Area 5 RWMS for disposal of low-level waste (LLW), mixed waste (MW), and transuranic waste (TRU). The primary purpose of the Pilot Well Project is two-fold: first, to characterize important water quality and hydrologic properties of the uppermost aquifer; and second, to characterize the lithologic, stratigraphic, and hydrologic conditions which influence infiltration, redistribution, and percolation, and chemical transport through the thick vadose zone in the vicinity of the Area 5 RWMS. This report describes Pilot Well drilling and coring, geophysical logging, instrumentation and stemming, laboratory testing, and in situ testing and monitoring activities.

Both in terms of volume and toxic pollutants, drilling muds and drill cuttings are the most significant waste streams from exploratory and development activities in the oil and gas industry. Under the Clean Water Act, the US Environmental Protection Agency (EPA) regulates discharges of all contaminants, including drilling muds, into the waterways and offshore areas of the United States. EPA employs technology-based effluent standards in issuing discharge permits to both onshore and offshore operators. This paper examines the regulatory approaches used by EPA to limit toxicity in drilling muds at offshore drilling platforms and discusses other measures EPA has adopted to reduce toxicity of drilling muds discharged offshore. This effort focuses on an innovative approach that emphasizes pollution prevention used by EPA Region X for offshore Alaska, which is contrasted with a more traditional command and control regulatory approach used by other EPA regional offices. The Region X approach includes collection of influent and effluent data, development of a comprehensive data base of technical information, and prescription of specific mud formulas. This influent-effluent approach reduces uncertainty and guesswork, enhances use of innovative technology, and lowers toxic discharges compared to the standard EPA command and control approach. The influent-effluent approach provides …

Geraghty & Miller, Inc. of Midland, Texas conducted geologic and hydrologic feasibility studies of the potential applicability of Jack McIntyre`s patented process for the recovery of natural gas from coalbed/sand formations in the Piceance Basin through literature surveys. Jack McIntyre`s tool separates produced water from gas and disposes of the water downhole into aquifers unused because of poor water quality, uneconomic lifting costs or poor aquifer deliverability. The beneficial aspects of this technology are two fold. The process increases the potential for recovering previously uneconomic gas resources by reducing produced water lifting, treatment and disposal costs. Of greater importance is the advantage of lessening the environmental impact of produced water by downhole disposal. Results from the survey indicate that research in the Piceance Basin includes studies of the geologic, hydrogeologic, conventional and unconventional recovery oil and gas technologies. Available information is mostly found centered upon the geology and hydrology for the Paleozoic and Mesozoic sediments. Lesser information is available on production technology because of the limited number of wells currently producing in the basin. Limited information is available on the baseline geochemistry of the coal/sand formation waters and that of the potential disposal zones. No determination was made of the …

The Volatile Organic Compounds (VOCs) in Non-Arid Soils Integrated Demonstration (ID) was initiated in 1989. Objectives for the ID were to test the integrated demonstration concept, demonstrate and evaluate innovative technologies/systems for the remediation of VOC contamination in soils and groundwater, and to transfer technologies and systems to internal and external customers for use in fullscale remediation programs. The demonstration brought together technologies from DOE laboratories, other government agencies, and industry for demonstration at a single test bed. The Savannah River Site was chosen as the location for this ID as the result of having soil and groundwater contaminated with VOCS. The primary contaminants, trichlorethylene and tetrachloroethylene, originated from an underground process sewer line servicing a metal fabrication facility at the M-Area. Some of the major technical accomplishments for the ID include the successful demonstration of the following: In situ air stripping coupled with horizontal wells to remediate sites through air injection and vacuum extraction; Crosshole geophysical tomography for mapping moisture content and lithologic properties of the contaminated media; In situ radio frequency and ohmic heating to increase mobility, of the contaminants, thereby speeding recovery and the remedial process; High-energy corona destruction of VOCs in the off-gas of vapor recovery …

A technique was developed to extract iodine from groundwaters with very low concentrations of iodine (on the order of {mu}g/L or ppb). Sufficient iodine was necessary (approximately 5 mg Agl) for analysis of the {sup 129}l/{sup 127}l on the Tandem Accelerator Mass Spectrometer (AMS). The technique for separating iodine from groundwater was developed for the field to eliminate shipping of thousands of liters of water back to the laboratory. The technique was field tested on several springs and wells at the Nevada Test Site (NTS). Preliminary isotope ratios are presented along with total iodine concentrations of the waters. It was also determined that iodine may be used as an early radionuclide migration tool.
