fairly steady for the remainder of the year. These water level declines are thought to be due to <br />drilling for deeper coal in this area. Backfill well GD -3 is approximately 1200 feet upgradient of <br />well GD -2. It is topographically higher and closer to D pit. Water -level changes in well GD -3 have <br />been more gradual than changes in well GD -2. The unconfmed backfill aquifer's storage parameter <br />would be much larger than the storage coefficient for the confined aquifer at GD -2 and, therefore, <br />would be expected to dampen responses. <br />Water levels in well GP -9 gradually increased in 2006. This water -level change is likely <br />natural. <br />The GE wells (GE -1, GE -2, GE -3) are near 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-4 and A -5. Water levels in wells GE -1, GE -2 and GE -3 <br />were fairly steady with a small overall decline in the first half of 2006. Water levels in these three <br />wells did not respond to the larger precipitation in 2005 and 2006. These changes are likely due to <br />variations in recharge. Figure A -5 also presents water levels for wells 81 -03A and GLUX -1, which <br />are completed m the 3rd and 1st White Sandstone aquifers, respectively. The first half of 2006 <br />water levels in well 81 -03A overall were steady after declining in 2004 and previous years. Water <br />levels increased in 2006 in well GLUX -1 after a gradual decline for several years. The higher <br />precipitation in 2005 and 2006 stopped the decline. <br />Figure A -6 presents water levels for wells GF -7 and P -8. These wells are completed in <br />the HI backfill and 3rd White Sandstone aquifers, respectively. Water levels in well GF -5 (see <br />Figure A -1) and GF -7 (see Figure A -6) were steady in 2006 (both completed in the HI backfill). <br />The larger storage value in the unconfmed backfill aquifer may dampen the effects of dry and wet <br />years. The recovery from the A pit mining in this area may be complete. The water levels in well <br />P -8 very gradually declined in 2006. <br />Trapper Mining Company 2 -5 <br />2006 Annual Report <br />
