Figure A-8 presents water levels for wells GF-1, GF-7 and P-8. These wells are '. completed in the 20 Mile, HI backfill and 3rd White Sandstone aquifers, respectively. Well GF-1 is a flowing well. Water levels in GF-1 rose in early 1997 but declined for the remainder of the year. Water levels in this deep aquifer would not be expected to quickly respond to either a low or high precipitation event, but seems to be affected by the variations in precipitation. As with GF-5, well GF-7 (both completed in the HI backfill) continues to gradually recover. The larger storage value in the unconfined backfill aquifer may dampen the effects of dry and wet years. A small amount of recovery from the A pit mining in this area may still be occurring. The response seen at well P-8 is due to seasonal variations in recharge. Water levels for wells GF-2 and GF-4 are presented in Figure A-9. Water levels in these wells have been quite stable for a number of years. The U aquifer lies beneath the '. coal horizons. Mining occurred south of well GF~ in the early 1980's and seems to have made the water levels in this area of the HI aquifer very steady. Water levels in the upgradient unconfined backfill aquifer do not fluctuate as much as the confined HI aquifer. Figure A-10 presents water levels for wells GF-3 (KLM aquifer) and Coy (alluvium). Small increases were observed at GF-3, probably due to increased precipitation observed during 1995, 1996 and 1997. Water levels at Coy have gradually increased since late 1995 due to the significant increase in precipitation during 1995, 1996 and 1997. The unconfined alluvial aquifer responds gradually to recharge changes. Wells GF-6 and GF-11 are completed in the QR aquifer and QR backfill, respectively. They are located downgradient of the inactive E pit. GF-11 is 1150 feet upslope and upgradient of GF-6. The rise in 1997 has been larger in well GF-11 than in ', 2-6
