in the HI, 3rd White, and Qal aquifers, respectively. The water-level changes in these wells are <br />good indicators of natural recharge impacts on these aquifers. Water levels in well GCl (Figure <br />2-])have been fairly stable since the wet years 1983-1984. Water levels in wells GC2 and GC3 both <br />reflect seasonal variations with a slight lag from precipitation events. The deeper the aquifer, the <br />more dampened the response (+/- 1 or 2 ft. for the 3rd White Sandstone). <br />Figure A-9 presents the static water-level elevations for flowing well GD2. Between 1988 <br />and ]992, water levels have varied over an annual range of five to ten feet, possibly reflecting <br />seasonal influences. A dramatic rise of 32 ft. was observed from September, 1992, to October, <br />1993, followed by a significant decline in 1994. This well is completed in the QR aquifer and is <br />located downgradient of a reclaimed area containing backfill. This water-level decrease likely <br />resulted from a decrease in precipitation/ recharge (Figure 2-1). <br />GD3 is approximately 1200 ft. upgradient of well GD2. It is topographically higher and <br />closer to D pit and is completed in backfill. Its 1993 water levels show the same response that <br />occurred in 1993 in well GD2 but water levels in well GD3 did not similarly decline in 1994. <br />The GE wells (GEI, GE2, GE3) are near the northwest comer of the PA. They are <br />completed in the QR, HI, and 2nd and 3rd White aquifers, respectively. Water levels for these wells <br />are presented in Figures A-11, A-12, and A-13. Wells GE1 and GE2 are showing slight recovery <br />since 1993 while GE3 has remained steady after a decline from 1989 to 1992. The water level rise <br />in wells GEl and GE2 could be due to a lag in recharge for these deeper aquifers or could be a result <br />of recovery after the B and C pit mining in this area. <br />Water levels for the GF wells are tabulated in Tables A-4, A-5, and A-6 of Appendix A. <br />Plots of water level versus time aze presented for each well. GF1, GF2, GF3, and GF4 are located <br />i <br />2-5 <br />
