| Abstract: | Data on drilling operations, lithology, borehole geophysics, water level monitoring, core analysis, groundwater chemistry, pumping tests, and packer-injection tests are reported for test well USW H-5. The well is one of a series of test wells drilled in and near the southwestern part of the Nevada Test Site, Nye County, Nevada, in cooperation with the U.S. Department of Energy. These test wells are part of the Nevada Nuclear Waste Storage Investigations to identify suitable sites for storage of high-level radioactive wastes. Test well USW H-5 was drilled to a total depth of 1,219 m through volcanic rocks consisting mostly of ash-flow tuff. Depth of water in the well ranged between 703.8 and 707.2 m below land surface, at an approximate altitude of 704 m above sea level. Drawdown in the well exceeded 6 m after test pumping more than 3,000 min at a rate of 10 L/sec. Borehole flow surveys showed that about 90% of the water in the well is contributed by the zone between 707 and about 820 m below land surface. Two composite water samples collected after well completion contained 206 and 220 mg/L of dissolved solids. Sodium and bicarbonate were the predominant dissolved anion and cation. The concentration of dissolved silica was 48 mg/L in both samples, which is a relatively large concentration for most natural waters. (Author ‘s abstract) |
