• (9/92-8/93) of 6.4 ft. and GP4 a 0.9 ft. increase. Water-level <br />declines in well GP3 may be reflecting upgradient mining operations <br />but some of the changes are likely due to seasonal variations in <br />recharge. <br />Wells GP5 and GP6 are both completed in the QR aquifer. GP5 <br />is immediately downgradient of A pit and GP6 is immediately <br />upgradient of the pit. Water level data is tabulated in Table A-7. <br />Figures A-26 and A-27 present water level versus time_ Both plots <br />are similar, particularly since 1990. Both show increases in late <br />1992 with a decrease in mid-1993. GP5 demonstrates a maximum <br />increase of 15.7 ft. ending the year (9/92-8/93) with a net <br />increase of 9.2 ft. from 1992. GP6 had a maximum increase of 3 ft. <br />with a net annual change of +1.5 ft. These responses are <br />interpreted to be due to seasonal variations in recharge. <br />Wells GP7 and GP8 are located very near the eastern boundary <br />of the PA. They are completed in the KLM and HI aquifers and <br />provide undisturbed baseline data for these intervals. GP7 (Figure <br />A-28) indicates stable water levels following a gradual decline <br />from 1988 to 1989. GPS (Figure A-29) shows a steeper decline from <br />1988 to 1989 flattening to a lower rate of decline. Both wells are <br />interpreted as showing natural responses with a very dampened <br />response and lag to recharge events. These wells are in steep <br />terrain where recharge may be limited~by rapid runoff. Figure A-30 <br />presents the natural variations in water levels for the 3rd White <br />Sandstone aquifer in well GP9. Note that water-level elevations <br /> <br />2-9 <br />
