provide undisturbed baseline data for these intervals. Wells GP-7 and GP-8 show fairly • <br />stable water levels for the last two years. Both wells are interpreted as showing natural <br />responses with a very dampened response to the 1995 and 1996 recharge events. <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-14 and .A-15 <br />show similar responses from 1986 through 1996, with a sharp decline in water levels seen <br />in 1994, as well as a fairly sharp rise in 1996. Recent water-level increases in these wells <br />may be reflecting the increased precipitation/recharge occurring in 1995 and 1996. Water <br />levels in well GP-3 are recovering to near pre-mine levels in this area and indicate that the <br />upgradient mining did not significantly affect the water levels in the HI 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. V'Jater <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 />tabulated in Table A-1 in Appendix A. Figures A-16 and A-17 present water level versus <br />time plots. Both plots are similar, with an overall rising trend observed during the last two <br />years. These responses are interpreted to be due to seasonal variations in recharge due <br />to the large distance to active QR mining. <br />Figure A-16 presents the change in water-level elevation for alluvial well P-1, <br />located in the Pyeatt drainage north of the PA. This data demonstrates classic seasonal <br />responses, highs in wintedspring and lows in late summer/fall. An overall increasing trend <br />occurred beginning in 1992. Well P-3 is completed in the Lewis Shale outcrop, which is in <br />2-8 <br />
