• aquifer as mining in the A pit moves away from this area . The <br /> rate of water-level rise seems to have decreased some since 1987 <br /> indicating a possible stabilizing of water levels. Levels <br /> probably recovered from mining in this area much faster due to <br /> the high precipitation during 1983 through 1986. The stabilizing <br /> of the levels and the slight decline in the last half of 1989 could <br /> be partially caused by the decline in recharge since 1986 (see <br /> Figure 2-1 ) . <br /> The GC wells are approximately two and one-half miles from <br /> the nearest mining in the H and I coal seams. Well GC1 is <br /> completed in the HI aquifer and has shown a considerable amount <br /> of water-level fluctuation which is all thought to be natural . <br /> • Figure A-6 shows that water levels have shown little variation <br /> since 1987 indicating very little change in storage in the HI <br /> aquifer in this area. Water levels responded to the increase in <br /> recharge in 1984 and 1985. <br /> The water levels from the Third White Sandstone well (GC2) <br /> show that water levels had been fairly steady in this well from <br /> 1984 through 1987. The hydrograph for this well shows a slight <br /> decline in late 1988 through 1989. Water levels from well GC2 and <br /> GB2 indicate that water levels in the Third White Sandstone have <br /> not significantly been affected by the precipitation variations. <br /> The hydrograph for alluvial well GC3 presents declining levels <br /> through 1988 and 1989 with the Spring 1989 water level showing a <br /> higher level . This corresponds well to the low amount of <br /> • precipitation received in 1988 and 1989. <br /> 2-6 <br />
