Water levels for the GF Wells are tabulated in Tables A-4, <br />A-5, and A-6 of Appendix A. Plots of water level versus time are <br />presented for each well. GF1, GF2, GF3, and GF4 are located <br />downslope and downgradient of A and E pits, slightly greater than <br />1000" downgradient of the A pit. These wells are downgradient from <br />the A and E pits in native ground. The wells are completed in the <br />20 Mile, U, KLM, and HI aquifers, respectively. The GF1 and GF3 <br />are flowing wells, The GF2 previously flowed until the casing was <br />extended in 1985. Water levels in the GF1 (Figure A-14) have <br />varied over a five foot range during the last year but overall are <br />stable to slightly decreasing. The GF2 (Figure A-15) is very <br />stable. The 20 Mile and U aquifers both lie beneath the coal <br />horizons. The changes in the GF1 and GF2 most likely represent <br />natural variations in recharge, The GF3 water level had been <br />fairly steady from 1988 through 1992, then exhibited a 16 ft. <br />downward spike, recovering to near the previous year's level in <br />October. The August, 1993, value may be due to a measurement <br />error. Well GF4 has been quite stable. Wells GF3 and GF4 <br />demonstrate recovery and stabilization of the KLM and HI aquifers <br />at this site. <br />Well GF5 is completed in "HI" backfill and is located <br />approximately 2800' WSW of GF4. Figure A-18 shows a gradual <br />declining trend from recovery in 1988 to late 1992, when a slight <br />rise commenced, possibly in response to increased precipitation and <br />recharge. Well GF7 is 3300' east of GF5 and is also completed in <br />backfill. Figure A-20 shows an increase similar to GF5. Wells at <br />2-7 <br />
