• recover. Figure A-8 shows that the water levels have remained fairly uniform since 1993 even with <br />the decline in precipitation in 1994. The lazger storage value in the unconfined backfill aquifer and <br />partially saturated zone above the water table may delay the effects of dry and wet years. The GF-7 <br />response is considered a natural response to variations in recharge to this backfill aquifer. A small <br />amount of recovery from the A pit mining in this area may still be occurring. The response seen at <br />well P-8 is due to seasonal variations in recharge. <br />Water levels for wells GF-2 and GF-4 are presented in Figure A-9. Water levels in these <br />wells have been quite stable for a number of years. The U aquifer lies beneath the coal horizons. <br />Mining has not occurred near GF-4 in recent years thereby, not affecting its water levels. <br />Figure A-10 presents water levels for wells GF-3 (KLM aquifer) and Coy (alluvium). the <br />small increase seen at GF-3 is probably due to increased precipitation observed during 1995. Water <br />• levels at Coy have remained steady despite the significant increase in precipitation in 1995. The <br />third quarter 1995 reading is thought to be a measurement error. <br />Wells GF-6 and GF-11 are completed in the QR aquifer and QR backfill, respectively. <br />They aze located downgradient of the inactive E pit. GF-11 is 1150' upslope and upgradient of GF-6. <br />In 1995, both wells experienced similar water level increases between the first and fourth quarters <br />(Figure A-11). These increases observed in both wells are probably due to more recharge in 1995. <br />The water-level response in this backfill well responds similar to the confined QR aquifer. <br />The GP-1 and GP-2 wells (Figures A-12 and A-13) aze located in an undisturbed area near <br />the eastern boundary of the Permit Area. They provide a natural baseline for the QR and KLM <br />aquifers. Overall, the water levels have increased during 1995 in response to an increase in <br />precipitation. <br />2-7 <br />
