• due to the slightly below normal precipitation. The alluvial aquifer response is generally of <br />a larger magnitude. <br />Figure A-4 presents the static water-level elevations for wells GD-2, GD-3 and <br />GP-9. These wells are completed in the QR, QR backfill and 3rd White Sandstone aquifers. <br />In 2000, water levels in wells GD-2 and GD-3 declined. The water-level elevation in 2000 <br />for well GD-3 is several feet higher than the level downgradient at well GD-2. Well GD-3 is <br />approximately 1200 feet upgradient of well GD-2. It is topographically higher and closer to <br />D pit and is completed in backfill. Water-level changes in well GD-3 have been more <br />gradual than changes in well GD-2. The unconfined backfill aquifer's storage parameter <br />would be much larger than the storage coefficient for the confined aquifer at GD-2 and, <br />therefore, would be expected to dampen responses. <br />• ~ Water levels gradually declined in well GP-9.likely due to less to precipitation. <br />This water-level change is likely natural. <br />The GE wells (GE-1, GE-2, GE-3) are near the northwest wmer 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-5 and A-ti. Wells GE-1 and GE-2 <br />have continued to gradually recover since 1993, while levels in well GE-3 gradually <br />dedined in 2000 after a rising trend during the higher precipitation years. The water-level <br />rise in wells GE-1 and GE-2 is likely due to recovery from previous mining in the area. <br />Figure A-6 also presents water levels for wells 81-03A and GLUX-1, which are completed in <br />the 3rd and 1st White Sandstone aquifers, respecctivvely. The 2000 water levels in well 81- <br />03A have been steady but slightly greater than the 1998 values. Water levels show an <br />• overall gradual decline over the last few years in well GLUX-1. <br />2-5 <br />
