Available in PDF, EPUB and Kindle. Book excerpt: More than 500 domestic, agricultural, and monitoring wells were identified in the Amargosa Valley. From this list, 80 wells were identified as potential hydrologic characterization wells, in support of the US Department of Energy (DOE) Underground Test Area/Remedial Investigation and Feasibility Study (UGTA/RIFS). Previous hydrogeologic studies have shown that groundwater flow in the basin is complex and that aquifers may have little lateral continuity. Wells located more than 10 km or so from the Nevada Test Site (NTS) boundary may yield data that are difficult to correlate to sources from the NTS. Also, monitoring well locations should be chosen within the guidelines of a hydrologic conceptual model and monitoring plan. Since these do not exist at this time, recompletion recommendations will be restricted to wells relatively close (approximately 20 km) to the NTS boundary. Recompletion recommendations were made for two abandoned agricultural irrigation wells near the town of Amargosa Valley (previously Lathrop Wells), for two abandoned wildcat oil wells about 10 km southwest of Amargosa Valley, and for Test Well 5 (TW-5), about 10 km east of Amargosa Valley.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this investigation is to estimate vertical fluid flux rates in saturated units penetrated by selected wells at the Nevada Test Site (NTS) using geothermal gradient data. Estimates of vertical fluid flux rates are critical in developing models for contaminate flow within, recharge potential to, and discharge from the groundwater system at the NTS. If temperature in the well is in equilibrium with the surrounding rocks, it is possible to detect the vertical flow of groundwater from the well's thermal profile. Heat in the subsurface is transported by conduction through the rock and by advection caused by subsurface water movement. Units in which vertical flow is occurring will produce a curve in the thermal profile within the well. Prior to the implementation of the Underground Test Area Remedial Investigation/Feasibility Study (UGTA RI/FS), investigation of thermal data from wells at the NTS was hindered by the completion of wells as open holes or without casing cemented in place. The open-hole type of completion allows cross-flow within the wellbore which can yield information about relative pressures between connected aquifers, but which renders thermal gradient data essentially useless, or at best highly suspect for interpreting in situ groundwater movement. Wells recently completed in the Department of Energy (DOE) Environmental Restoration (ER) Program have been completed with casing cemented to the surface (to prohibit cross-flow between units in the annular space between the casing and the wellbore) and with completion zones open to a single hydrologic horizon. This type of completion results in temperature gradient profiles more representative of actual thermal conditions in the units penetrated by the well. Results are presented of temperature profiles of 3 wells located in the Death Valley Groundwater Basin, outside the southern border of the NTS.

Available in PDF, EPUB and Kindle. Book excerpt: Monitoring for the migration of contaminants in groundwater or for the proper design of nuclear test emplacement holes at the Nevada Test Site (NTS) requires proper placement and completion of monitoring wells. This is only possible if the hydrogeologic system is understood in a regional and local context, necessitating data from existing wells and boreholes. Though the NTS Groundwater Characterization Project will be drilling wells, their great expense limits the number of new wells. However, there are many existing boreholes and wells on the NTS which have not been completely evaluated hydrologically. Some of these are incorporated in the Long Term Hydrologic Monitoring Program (LTHMP) of the US Environmental Protection Agency (EPA), others are related to the testing programs. In all cases, additional site investigation in necessary to properly interpret the hydrogeologic data from these wells. Monitoring wells on the NTS are poorly characterized with regard to aquifers penetrated, vertical hydraulic gradients, and vertical variations in water quality. One of the goals of the well validation program was to gain a thorough understanding of the parameters needed to interpret the source and fate potential hazardous and radioactive substances that may be detected in these wells in the future. One of the most critical parameters for monitoring is the knowledge of what aquifer or geologic unit is being sampled when a water sample is collected. Pumped water samples are weighted most heavily to the water quality of the most productive (highest transmissivity) aquifer penetrated by the well.

Book excerpt: The purpose of this environmental impact statement (EIS) is to provide information on potential environmental impacts that could result from a Proposed Action to construct, operate and monitor, and eventually close a geologic repository for the disposal of spent nuclear fuel and high-level radioactive waste at the Yucca Mountain site in Nye County, Nevada. The EIS also provides information on potential environmental impacts from an alternative referred to as the No-Action Alternative, under which there would be no development of a geologic repository at Yucca Mountain.
