newly installed well is the Glux-1 well outside Trapper's permit <br />area to the northwest. Table 1-1 presents the basic well data <br />for all the Trapper Mine ground-water monitoring wells. <br />Single-well pump tests were conducted on the three new wells <br />and backfill well GF7 which was completed during 1987. <br />Transmissivity for backfill well GD3 was calculated to be 1445 <br />gal/day/ft with a permeability of 4.G3 ft/day. The backfill <br />material in D pit has a much higher transmissivity than other <br />backfill areas and the native material in D pit (well GD2> has a <br />high transmissivity when compared to other native QR aquifer <br />wells. <br />Wells GF7 and GF11 had transmissivities of 160 gal/day/ft <br />and 116 gal/day/ft far the backfill in A pit and E pit, <br />• respectively. The backfill material in general seems to be <br />approximately ten times mare permeable than the native material. <br />The Glux-1 well was completed upgradient of the Lux domestic <br />well in the First White Sandstone. The single-well pump test on <br />it yielded a low transmissivity of 25 gal/day/f t. All pump tests <br />were analyzed with the Jacob method which uses the straight line <br />fit of the drawdown versus time since pumping started data to <br />obtain transmissivities and permeabilities. Table 2-1 presents <br />the summary of aquifer properties for Trapper Mine wells as of <br />1988. Appendix D presents the pump-test data and the plots of <br />the drawdown data versus time since pumping started for the <br />respective wells. <br />u <br />2-15 <br />
