Well GP-2 (Figure A-10) is located in a previously undisturbed area near the eastern <br />boundary of the PA. Water levels rose in the second quarter of 2005 in well GP-2 then gadually <br />declined the remainder of the year. The overall decline the last three years followed a rise in 2002 <br />which were preceded by a larger decline. <br />Wells GP-3 and GP-4 are less than 1000 feet downgradient from A pit. Both are flowing <br />wells completed in the HI and KLM aquifers, respectively. Water Ievels in these two wells had <br />shown similar responses in water levels due to changes in precipitation but the 2005 water level <br />changes were different (see Figures A-11 and A-12). Water levels in well GP-3 have recovered to <br />above pre-mine levels in this azea and show that any depletion of water from upgradient mining has <br />been replaced by recharge to the HI aquifer. The overall gradual declines in water levels in well GP- <br />3 in the years just prior to 2005 are probably a function of below normal precipitation during this <br />period The water level in well GP-4 has also recovered to pre-mine levels but observed variable <br />levels in 2005. <br />Well GMP-1 (Figure A-11) is completed in the HI aquifer to monitor Bound-water <br />conditions downgadient of the ash disposal site immediately south in A pit. Water levels became <br />steady in 2001 and stayed fairly steady the last five yeazs with a small increase in 2005. <br />Figure A-12 also presents water levels for the well COY (allu,,A'um). Water levels at the <br />COY well overall rose in 2005 likely due to an increase in recharge. The unconfined alluvial aquifer <br />generally responds gadually to rechazge changes. a <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 upgadient of the pit. Water-level data is tabulated <br />in Table A-1 in Appendix A. Figures A-13 and A-14 present water level versus time plots. Both <br />plots aze fairly similar, with fairly steady water levels in wells GP-5 and GP-6 in 2005.
