recovery from mining. The water-level response in this bacldill well has been greater over <br /> the last two years than in the confined QR aquifer at well GF-6. <br /> The GP-1 and GP-2 wells (Figures A-11 and A-12) are located in an undisturbed <br /> area near the eastern 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 for the last four years in <br /> response to an increase in recharge in the spring, while levels in well GP-2 also increased <br /> in the spring of 1998. <br /> Figure A-11 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 1998. Both of these wells show natural responses with a very <br /> . dampened response to higher precipitation over the last four years. <br /> Wells GP-3 and GP-4 are less than 1000 feet downgradient from A pit. Both are <br /> flowing wells completed in the HI and KLM aquifers, respectively. Figures A-13 and A-14 <br /> show similar responses to the increase in precipitation over the last four years, with water <br /> level rises. Water levels in well GP-3 have recovered to above pre-mine levels in this area <br /> and show that any depletion of water from upgradient mining has been replaced by <br /> recharge to the HI aquifer at well GP-3. The water level in well GP-4 has also recovered to <br /> pre-mine levels. <br /> Well GMP-1 (Figure A-13) 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 and will likely still <br /> • recover more. <br /> 2-7 <br />
