<br />pit aril is completed in backfilL Water-level changes in well GD-3 have been more gradual than <br />changes in well GD-2. The unconfined backfill aquifer's storage parameter would be much larger than <br />the storage coefficient for the confined aquifer at GD-2 and, therefore, would be expected to dampen <br />responses. <br />Water levels in well GP-9 gradually increased in 2004. This water-level change is Irkely <br />natural. <br />The GE wells (GE-1, GE-2, GE-3) are near the northwest corner of the PA. They are <br /> <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-4 and A-5. Water levels in wells GE-1, GE-2 and GE-3 were <br />fairly steady with a small overall decline in 2004 after a rising trend during the higher precipitation <br />years. These changes are likely due to variations in recharge. Figure A-5 also presents water levels <br />for wells 81-03A and GLUX-1, which are completed in the 3rd and 1st White Sandstorm aquifers, <br />respectively. The 2004 water levels in well 81-03A declared steadily ar 2004 after a rise in late 2003. <br />Water levels show an overall gradual decline over the last few years in well GLUX-1 hlcely due to less <br />precipitation the last seven years. <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 and GF-7 (see <br />Figure A-1) gradually declined in 2004 (both completedm the HI backfiln. The larger storage value in <br />the unconfined backfill aquifer may dampen the effects of dry and wet years. The recovery from the A <br />pit mining in this area maybe complete. The water levels ar well P-8 overall gradually declined in 2004 <br />except for a questionable dry level in the second quarter. <br />Water levels for well GF-4 are presented in Figure A-7. A large rise in water level in well <br />GF-4 was observed in the last half of 1999 after the repay of the casing on September 29, 1999. Water <br />levels were overall steady in 2004 in well GF-4 with a small increase in tbe second quarter due to <br />Trapper Mining Company <br />2004 Annual Report <br />
