variations in recharge. These changes may lag the actual precipitation events due to the <br />time it takes the head change to move through the aquifer to the monitoring well. <br />Wells GP-1, GP-5 and GP-6 are useful in defining natural variations in the QR <br />aquifer for 2001. Water levels in wells GP-5 and GP-6 show a rising trend from 1995 <br />through 1998 with fairly steady water levels the last three years with some increase in <br />2001. Water levels in well GP-1 have been declining significantly over the last three years. <br />Well GP-8 has been used as a baseline for precipitation/recharge impacts on the KLM <br />aquifer and showed a significant decline in water levels during 2001. Mining is close <br />enough to this well in 2001 that its water level responses have to be used with caution <br />relative to baseline conditions. <br />Figure A-1 presents water levels versus time for wells GB-1, GB-5, GF5 and P-5. <br />The wells are completed in the KLM, HI, HI backfill and 2nd White Sandstone aquifers, <br />respectively. Fgure A-1 shows steady increases in water levels for GB-1 since air-lift <br />production ceased in 1993. Recovery in this well may still be from the earlier air-lift <br />production. Water levels in wells GB-5 and GF-5 were steady in 2001, while water levels in <br />well P-5 stayed low in this aquifer in 2001. HI well GP-7 (Fgure A-11) should show natural <br />variations in the HI aquifer for 2001 and water levels in this well showed a small decline in <br />2001. Water levels continue to rise in well GB-2, probably in response to recovery at its <br />location downgradient of a reclaimed pit (see Figure A-2). The last measurement indicates <br />a start of a decline. <br />The GC wells (GC-1, GC-2, GC-3, see Figure A-3) are located near the northeast <br />comer of the permit area (PA) slightly more than 1100 feet from mining activity in 2001. <br />These wells are completed in the HI, 3rd White and alluvial aquifers, respectively. The <br />water-level changes in these wells may not still be good indicators of natural recharge <br />2-4 <br />
