Hydrogeology of rocks penetrated by test well JF-3, Jackass Flats, Nye County, Nevada

Analysis of aquifer tests conducted in boreholes USW WT-10, UE-25 WT No. 12, and USW SD-7, 1995-96, Yucca Mountain, Nevada

“…It is doubtful that the drawdown rate would change significantly when the borehole was being pumped at a discharge rate that was far below its maximum yield. Transmissivities determined from the 24-hour specific-capacity estimates are within the range of estimates determined in other Yucca Mountain area wells (Thordarson, 1983;Thordarson and Howells, 1987;Plume and La Camera, 1996). Additional aquifer tests at higher discharge rates are needed to better define the transmissivity at this site.…”
