GF-6 (see Figure A-11). These increases observed in both wells are probably due to more <br />recharge in the last three years. The water-level response in this backfill well responds <br />similar to the confined QR aquifer. <br />The GP-1 and GP-2 wells (Figures A-12 and A-13) are located in an undisturbed <br />area near the eastem boundary of the PA. They provide a natural baseline for the QR and <br />KLM aquifers. Overall, the water levels in well GP-1 increased from 1995 through 1997 in <br />response to an increase in precipitation, while levels in well GP-2 increased only in 1997. <br />Figure A-12 also presents water levels for GP-7 and GP-8, which are located very <br />near the eastern boundary of the PA. They are completed in the KLM and HI aquifers and <br />provide undisturbed baseline data for these intervals. Wells GP-7 and GP-8 show overall <br />gradual increases in 1997. Both wells are interpreted as showing natural responses with <br />• a very dampened response to the higher precipitations the last three years. <br />Wells GP-3 and GPI are less than 1000 feet downgradient from A pit. Both are <br />flowing wells completed in the HI and KLM aquifers, respectively. Figures A-14 and A-15 <br />show similar responses from 1986 through 1997, with water level rises from the higher <br />precipitation. Water levels in well GP-3 are recovering to near pre-mine levels in this area <br />and indicate that the upgradient mining did not significantly affect the water levels in the HI <br />aquifer at well GP-3. <br />Well GMP-1 (Figure A-14) was completed in the HI aquifer to monitor ground- <br />water conditions downgradient of the ash disposal site immediately south of A pit. Water <br />levels have continued to recover from the A pit mining in this area. <br />Wells GP-5 and GP-6 are both completed in the QR aquifer. GP-5 is immediately <br />downgradient of A pit and GP-6 is immediately upgradient of the pit. Water-level data is <br />2-7 <br />
