of higher precipitation. A similar response was observed in the other 3rd White Sandstone <br />well, GC-2, that must be responding to natural variations. <br />The GE wells (GE-1, GE-2, GE-3) are near the northwest comer of the PA. They <br />are completed in the QR, HI and 2nd and 3rd White Sandstone aquifers, respectively. <br />Water levels for these wells are presented in Figures A-6 and A-7. Wells GE-1 and GE-2 <br />continue to gradually recover since 1993 while, overall, GE-3 has remained fairly steady <br />over this same period. The water-level rise in wells GE-1 and GE-2 is likely due to recovery <br />from previous mining in the area. Figure A-7 also presents water levels for wells 81-03A <br />and GLUX-1, which are completed in the 3rd and 1st White Sandstone aquifers, <br />respectively. At 81-03A an increasing trend has been observed since 1993. This may be <br />due to a decrease in dewatering at an adjacent underground mine. Water levels have been <br />steady for the last two years in well GLUX-1. <br />Figure A-8 presents water levels for wells GF-1, GF-7 and P-8. These wells are <br />completed in the 20 Mile, HI backfill and 3rd White Sandstone aquifers, respectively. Well <br />GF-1 is a flowing well. Water levels in GF-1 sharply declined from mid-1993 through early <br />1995 and have increased since then. Water levels in this deep aquifer would not be <br />expected to quickly respond to either a low or high precipitation event, but seems to be <br />affected by the variations in precipitation. As with GF-5, well GF-7 (both completed in the <br />HI backfill) continues to gradually recover. The larger storage value in the unconfined <br />backfill aquifer may dampen the effects of dry and wet years. A small amount of recovery <br />from the A pit mining in this area may still be occurring. The response seen at well P-8 is <br />due to seasonal variations in recharge. <br /> <br />2-6 <br />
