while 1998 through 2002 were below. Water levels in many of the wells reflect the natural <br />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-5 and GP-6 are useful in defining natural variations in the QR aquifer for <br />2002. Water levels in wells GP-5 and GP-6 show a rising trend from 1995 through 1998 <br />with an overall gradual rise from 1498 to 2002. Water levels in well GP-1 have been <br />declining significantly over the last three years. Well GP-8 has been used as a baseline for <br />precipitation/recharge impacts on the KLM aquifer and showed a significant decline in <br />water levels during 2001 and 2002. Mining is close enough to this well that its water level <br />responses cannot be used relative to baseline conditions for the last two years. <br />Figure A-1 presents water levels versus time for wells GB-1, GB-5, GF-5 and P-5. <br />S~ ~ <br />P~ <br />The wells are wmpleted in the KLM, HI, HI backfill and 2nd White Sandstone aquifers, <br />respectively. Figure 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 gradually declined in 2002, while water <br />levels in well P-5 stayed near the bottom of this well in 2002. Water level in HI well GP-7 <br />(Figure A-11) show a small decline in the HI aquifer for 2002 which is probably natural. <br />This well has to be used with caution as an indicator of natural changes due to the <br />closeness of mining. Water levels continue to rise in well GB-2, probably in response to <br />recovery at its location downgradient of a reclaimed pit (see Figure A-2}. The last two <br />measurements indicate a larger rise in the water level. <br />The GC wells (GC-1, GC-Z, GC-3, see Figure A-3) are located near the northeast <br />corner of the permit area (PA) slightly more than 1100 feet from mining activity in 2002. <br />These wells are completed in the HI, 3rd White and alluvial aquifers, respectively.
