Reduction of the well test data for test well USW H-1, adjacent to Nevada Test Site, Nye County, Nevada

The drawdown and recovery data for three pump tests, three recovery tests and six injection tests in well USW H-1 are reduced to determine hydraulic conductivity and storativity, assuming the medium is homogeneous, isotropic, and porous. Conductivity ranges from about 10-5 m/s in the upper zone tested to 10-10 m/s in the lower test zone, and storativity ranges from about 5 x 10-7 to about 0.5. This study was conducted to support assessment of the behavior of the groundwater system at Yucca Mountain near the Nevada Test Site in southwest Nevada. After the work for the report was completed, the US Geological Survey published estimates of hydraulic conductivity based on the same test data analyzed here. This report is therefore also an independent confirmation of hydraulic conductivity estimates for well USW H-1 for the saturated zone, as well as a listing of storativity estimates. 5 refs., 23 figs., 3 tabs
