Water level in well GP-5 is useful in defining natural variations in the QR aquifer for <br />2007. Water levels in well GP-5 show a rising trend from 1993 through 1998 with an overall <br />steady level from 1998 to 2002. Water levels in these two wells have been fairly steady the last five <br />years with a small increase in the levels in 2007. Well GP-8 has been used as a baseline for <br />precipitation/recharge impacts on the KLM aquifer and showed a significant decline in water levels <br />during 2001 through 2005 followed by a rise in 2006 and steady water level in 2007. Mining is <br />close enough to this well that its water level responses cannot be used relative to baseline <br />conditions for the last seven years. <br />Figure A-1 presents water levels versus time for wells GF-5 and P-5. The wells are <br />completed in the HI backfill and 2nd White Sandstone aquifers, respectively. Water levels in well <br />GF-5 slightly rose in 2007, while well P-5 stayed dry in 2007. Water Level in HI well GP-7 (Figure <br />A-9) shows an overall small decline in the HI aquifer during the last few years. This well has been <br />used in the past to observe natural changes in this aquifer. <br />The GC wells (GC-1, GC-2, GC-3, see Figure A-2) are located neaz the northeast corner <br />of the permit area (PA) slightly more than 1100 feet from mining activity in 2007. These wells are <br />completed in the HI, 3rd White and alluvial aquifers, respectively. The water-level changes in these <br />wells may not still be good indicators of natural recharge impacts on these aquifers due to the <br />upgradient mining. Water levels in well GC-1 were higher in 2002 through 2006 than they were in <br />2000 and 2001 but within natural variations while water levels declined in 2007. Arise and decline <br />in water level was observed in well GC-3 in 2007 but within natural changes previously observed. <br />Water levels in well GC-2 gradually rose in 2007. These changes in these three wells are probably <br />natZU~al. The alluvial aquifer response indicates less recharge in 2007 than in 2005. <br />Figure A-3 presents the static water-level elevations for wells GD-2, GD-3 and GP-9. <br />These wells are completed in the QR, QR backfill and 3rd White Sandstone aquifers. In 2006, <br />water levels in wells GD-2 and GD-3 declined sharply the first quarter of 2006 and then became <br />Trapper Mining Company 2'`l <br />2007 Annual Report <br />• <br />• <br />• <br />
