variations. GC2 and GC3 both reflect seasonal variations with a <br />slight lag from precipitation events. The deeper the aquifer, the <br />more dampened the response (+/- 1 or 2 ft. for the 3rd White <br />Sandstone). <br />Figure A-9 presents the static water-level elevations for <br />flowing well GD2. Between 1988 and 1992, water levels have varied <br />over an annual range of five to ten feet, possibly reflecting <br />seasonal influences. A dramatic rise of 32 ft. has been observed <br />from September, 1992, to October, 1993. This well is completed in <br />the QR aquifer and is located downgradient of a reclaimed area <br />containing backfill. This water-level increase is resulting from <br />recovery in the upgradient reclaimed area, the shut-down of <br />dewatering wells in D pit, and an increase in precipitation/ <br />recharge (Figure 2-1). <br />GD3 is approximately 1200 ft. from GD2. It is topographically <br />higher and closer to D pit and is completed in backfill. Its water <br />levels show the same response as GD2 indicating it is being <br />influenced by similar factors. <br />The GE wells (GE1,1 GE2, GE3) are near the northwest corner of <br />the PA. They are completed in the QR, HI, and 2nd and 3rd White <br />aquifers, respectively. Water levels for these wells are presented <br />in Figures A-11, A-12, and A-13. Each well demonstrates recovery <br />and the shallower GE2 and GE3 show slight declines from 1990-1993. <br />With the closure and reclamation of B and C pits, the 1990-1993 <br />changes are presumed to be natural. <br />2-6 <br /> <br />
