Well GAl (QR aquifer) water levels (Figure A-1) were fairly steady in late 1991 and early <br />1992, probably reflecting a balance in natural recharge and de~vatering in the adjacent D pit. A <br />slight rise in water level was noted in December, 1992, followed by a large increase of 19.9 ft. <br />between March and June, ]993, remaining at that level for the rest of the year. A decline was <br />observed in ] 994 due primarily to a decrease in annual precipitation. The KLM and QR wells, used <br />as a baseline for precipitation/recharge impacts on undisturbed aquifers (GPI, GP2, and GPb) <br />showed declines in water-level elevation due to the decreased precipitation received during 1994. <br />Well GA2 (KLM aquifer) is adjacent to GAl. Although completed in an aquifer above <br />the QR aquifer and sepazated from it by an aquitard, the water levels in this well decreased in a <br />manner similar to GA1. The well is very likely responding to the same factors affecting GA1. The <br />water-level elevation (8/94) in GA2 is approximately 30 ft. higher than in GAI. <br />Wells GB1, GB2, and GBS are located west of the active areas of the A pit, and near • <br />back-fill azeas in the A pit. These wells are offset to both the east and west by areas of backfill. The <br />wells are completed in the KLM, 3rd White, and HI aquifers, respectively. Figure A-3 shows steady <br />increases in water levels for GB1. The sharp decreases are representative of periods after air-lift <br />production. Recovery in this well may still be from the earlier air-lift production. GB2 (3rd White) <br />(Figure A-4) shows a gradual rise in water levels and is probably responding to recovery at its <br />location downgradient of a reclaimed pit. Figure A-5 (well GBS) illustrates a small recover}' of the <br />HI aquifer even with the 1994 below normal precipitation. The minor variations over the last few <br />years reflect natural recharge. <br />The GC wells (GCl, GC2, GC3-Figures A-b, A-7, A-8) are located near the northeast <br />comer of the permit area (PA) nearly two miles from mining activity. These wells are completed <br />2-4 <br /> <br />
