Figure A-1 presents water levels versus time for wells GB-1, GB-5, GF-5 and P-5. The wells are completed in the KLM, HI, HI backill and 2nd White Sandstone aquifers, respectively. Figure A-1 shows steady increases in water levels for GB-1 since air-lift production ceased in 1993. Recovery in this well may still be from the earlier air-fift production. Water levels in wells GB-5 and GF-5 were steady in 1999 after a gradual rise over the last few years. HI wells GC-1 and GP-7 should show natural variations in the HI aquifer for 1999 and their water levels showed a small decline in 1999. Water-level elevations in well P-5 have been fairly steady for the last few years. Water levels continue to rise in well GB-2, probably in response to recovery at its location downgradient of a reclaimed pit(see Figure A-2). The GC wells (GC-1, GC-2, GC-3, see Figure A-3) are located near the northeast comer of the permit area (PA) nearly one-half of a mile from mining activity. These wells are completed in the HI, 3rd White and alluvial aquifers, respectively. The water-level changes in these wells are still good indicators of natural recharge impacts on these aquifers. Water levels in well GC-1 gradually declined due to less recharge in 1999. Water levels in wells GC-2 and GC-3 both show a similar gradual water-level decline in 1999. The declines in all three wells are due to the decreased 1999 precipitation. The alluvial aquifer response is generally of a larger magnitude. Figure A-4 presents the static water-level elevations for wells GD-2, GD-3 and GP-9. These wells are completed in the QR, QR backfill and 3rd White Sandstone aquifers. In 1999, water levels in wells GD-2 and GD-3 were fairly steady with an overall small decline. The water-level elevation in 1999 for well GD-3 is several feet higher than the level downgradient at well GD-2. Well GD-3 is approximately 1200 feet upgradient of well 2-4
