levels in well GD-2 declined the first quarter of 2005 and rose the remainder of the year while levels <br />in well GD-3 in 2005 showed a rising water level. The water-level elevation in November 2005 for <br />well GD-2 rose several feet and should be used with caution until it is confirmed. Well GD-3 is <br />approximately 1200 feet upgradient of well GD-2. It is topographically higher and closer to D pit <br />and is completed in backfill. Water-level changes in well GD-3 have been more gradual than <br />changes in well GD-2. The unco~ned backfill aquifer's storage pazameter would be much lazger <br />than the storage coefficient for the confined aquifer at GD-2 and, therefore, would be expected to <br />dampen responses. <br />Water levels in well GP-9 gradually increased in 2005. This water-level change is likely <br />natural. <br />The GE wells (GE-1, GE-2, GE-3) aze neaz the northwest comer of the PA. They are <br />completed in the QR, HI and 2nd and 3rd White Sandstone aquifers, respectively. Water levels for <br />• these wells are presented in Figures A~ and A-5. Water levels in wells GE-1, GE-2 and GE-3 were <br />fairly steady with a small overall decline in 2005. Water levels in these three wells did not respond <br />to the lazger precipitation in 2005. These changes are likely due to variations in recharge. Figure A- <br />5also presents water levels for wells 81-03A and GLUX-1, which aze completed in the 3rd and 1st <br />White Sandstone aquifers, respectively. The 2005 water levels in well 81-03A overall increased in <br />2005 after declining in 2004. Water levels were fairly steady in 2005 in well GLiJX-1 after a gradual <br />decline for several years. The higher precipitation in 2005 stopped the decline in 2005. <br />Figure A-6 presents water levels for wells GF-7 and P-8. These wells are completed in the <br />HI backfill and 3rd White Sandstone aquifers, respectively. Water levels in well GF-5 (see Figure A- <br />1) and GF-7 (see Figure A-6) were steady in 2005 (both completed in the HI backfill). The larger <br />storage value in the unconfined backfill aquifer may dampen the effects of dry and wet years. The <br />• Trapper IvLning Company <br />2005 Annual Report <br />
