production. Water levels are slightly elevated at wells GB-5 and GF-5, probably due to the <br />significant 1995 precipitation. Small recovery is seen at well P-5, probably in response to increased <br />precipitation. Water levels continue to rise at GB-2, probably responding to recovery at its location <br />downgradient of a reclaimed pit (see Figure A-3 ). <br />The GC wells (GC-1, GC-2, GC-3-Figure A-4) are located near the northeast comer of <br />the permit area (PA) nearly two miles from mining activity. These wells are completed in the HI, <br />3rd White, and QAL aquifers, respectively. The water-level changes in these wells aze good <br />indicators of natural recharge impacts on these aquifers. Water levels in well GC-1 have been fairly <br />stable since the wet years 1983-1984. Water levels in wells GC-2 and GC-3 both reflect seasonal <br />variations with a slight lag from precipitation events. Increases were observed in all three wells due <br />to the increased 1995 precipitation. The deeper the aquifer, the more dampened the response (+/- <br />• 1 or 2 ft. for the 3rd White Sandstone). <br />Figure A-5 presents the static water-level elevations for wells GD-2, GD-3 and GP-9. <br />These wells aze completed in the QR, QR backfill and 3rd White Sandstone aquifers. Between 1988 <br />and 1992, water levels at GD-2 have varied over an annual range of five to ten feet, possibly <br />reflecting seasonal influences. A dramatic rise of 32 ft. was observed from September, 1992, to <br />October, 1993, followed by a significant decline in 1994. In 1995 water levels increased slightly <br />and remained fairly steady during the yeaz (as opposed to most previous years). The steadiness seen <br />in 1995 is probably due to a balancing of increased precipitation with increased dewatering at Pit <br />D. <br />GD-3 is approximately 1200 ft. upgradient of well GD-2. It is topographically higher and <br />• closer to D pit and is completed in bacl~'ill. Its 1993 water levels show the same response that <br />2-5 <br />
