Well GF7 was completed in the Fall of 1977 in backfill <br />material where the HI coal seam was mined. Figure A-20 presents <br />water-level data collected for well GF7. This hydrograph <br />indicates that water levels are slowly rising in the backfill <br />material near well GF7. Figure A-21 presents the water-level <br />elevation plot for well GF11 which was installed in July 1988 in <br />backfill material where the OR coal was mined and upgradient of <br />well GF6. This data indicates that the water levels in the <br />backfill are responding to the lower precipitation rates. <br />Figure A-22 presents the water-level elevation data for OR <br />aquifer well GP1. Well GP1 is a flowing well and well head <br />pressures have been converted to feet of water above the well <br />head. Water-level elevations for well GP1 reflect the decline in <br />• total precipitation since 1986. <br />Well GP2 is completed in the KLM aquifer. The water-level <br />elevation plot is shown on Figure A-23. Levels have shown a <br />decline for the two years since mid-1986. Changes in water-level <br />elevation in the KLM aquifer near well GP2 are not from mining <br />activities as the nearest mining is approximately two and one- <br />half miles away. Water-level elevation data for wells GP1 and <br />GP2 is tabulated in Table A-6. <br />Wells GP3 and GP4 are flowing wells and pressure readings <br />far them have been converted to water-level elevataion. Water- <br />level elevation data for well GP3 is tabulated in Table A-b. <br />Figure A-24 presents the plot of water-level elevation data <br />versus time for well GP3. Water levels for well GP3 <br />significantly declined in late 1987. Water levels appear to be <br />2-9 <br />
