• 1988. The 1989 levels showed little change from the 1988 levels. <br /> Water- level rises have been much less in the Third and Second <br /> White Sandstone and the greatest in the OR aquifer. Mining has <br /> occurred within 2000 feet of these wells in an adjacent <br /> underground permit, while the closest mining in Trapper ' s B and C <br /> pits is approximately 3000 feet from these wells. The majority of <br /> the drawdowns observed at these wells were probably not from <br /> Trapper Mine dewatering . The reduction in the rate of recovery <br /> of water level should gradually occur as the length of time since <br /> dewatering increases. This is likely the cause of the slower <br /> rates of water-level recovery in the GE wells, but the decline in <br /> precipitation and/or the dewatering that started in the C pit in <br /> • 1988 could be a cause. <br /> Water levels in the GF wells are tabulated in Tables A-4 , A- <br /> 5 and A-6 of Appendix A. Wells GF1 and GF3 are flowing wells, <br /> while the casing on well GF2 was extended in 1985 so it is no <br /> longer a flowing well . Figure A-14 shows the water-level <br /> elevations in the Twentymile Sandstone at GF1 . Water levels had <br /> shown little change since August 1987 . Water levels in well GF1 <br /> declined in early 1989 by approximately eight feet and have shown <br /> a recovery since then to a final 1989 level near those seen in <br /> previous years data. Water levels were gradually increasing in <br /> well GF2 (see Figure A-15) until mid-1987 when the levels <br /> declined . Levels in 1988 compared well with values seen in late <br /> 1986 and early 1987 . These values are approximately two feet <br /> . higher than Late 1987 values. The 1989 water levels are all <br /> 2-8 <br />
