impacts on these aquifers due to the upgradient mining. Water levels in well GGi were <br />higher in 2002 and 2003 than they were in 2000 and 2001 but within natural variations. <br />Similar water level changes were observed in well GC-3 in 2003. Water levels in well GC-2 <br />very gradualy increased in 2003. These changes in these three wells are probaby natural. <br />The alluvial aquifer response is generaly of a larger magnitude. <br />Fgure A-4 presents the static water-level elevations for wells GD-2, GD-3 and GP- <br />9. These wells are completed in the QR, QR baddill and 3rd White Sandstone aquifers. In <br />2003, water levels in wells GD-2 and GD-3 gradualy increased above the 2002 levels. The <br />water-level elevation in 2003 for well GD-3 is several feet higher than the level <br />downgradient at well GD-2. Well GD-3 is approximatey 1200 feet upgradient of well GD-2. <br />It is topographicaly higher and doser to D pit and is completed in bacldill. Water-level <br />changes in well GD-3 have been more gradual than changes in well GD-2. The unconfined <br />. backfill aquifer's storage parameter would be much larger than the storage coefficient for <br />the confined aquifer at GD-2 and, therefore, would be expected to dampen responses. <br />Water levels in well GP-9 gradualy incneased in 2003. This water-level change is <br />likey natural. <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, respectivey. <br />Water levels for these wells are presented in Fgures A-5 and A-6. Water levels in wells GE- <br />1, GE-2 and GE-3 were fairy steady with a small overall decline in 2003 after a rising trend <br />during the higher precipitation years. These changes are likey due to variations in <br />recharge. Figure A-6 also presents water levels for wells 81-03A and GLUX-1, which are <br />completed in the 3rd and 1st White Sandstone aquifers, respectively. The 2003 water levels <br />in well 81-03A varied significantly but overall were steady. Water levels show an overall <br />2-5 <br />
