remainder of the year. The water-level changes in well GA2 for the <br />past year showed a Spring rise of approximately one and one half <br />feet which was greater than the 1989 Spring rise. The water levels <br />showed a net decline of approximately four feet for the year. <br />Water levels in the KLM aquifer in this area rose in the past due <br />to higher rates of recharge, while the decline the last four years <br />is thought to be mainly caused by the decline in recharge. <br />Well G$1 is completed in the sandstone below the I coal (KLM <br />aquiferl and is located at the base of the A pit, where the H and <br />I coal seams were mined. Mining occurred in this area during <br />1985. Figure A-3 shows that water levels were rising at a steady <br />rate during the period 1985 through September 1987. Well GB1 was <br />• airlifted for production in September in 1987, 1988. 1989 and 1990 <br />for monitoring of the recovery of water levels. Data presented <br />from September through September of each of the last threevears <br />shows the recovery of water levels after production. This data <br />indicates that the recovery of water levels in well GB1 is very <br />slow with water levels not reaching the aquifer static level prior <br />to being airlifted the next year. Well GB1 is monitored only for <br />water-level data and is airlifted annually to test the <br />responsiveness of the well. Due to the very slow recovery of <br />water levels, a more accurate static water-level would be obtained <br />by not air lifting this well. Monitoring of this well should be <br />dropped because the data is not useful and well GBS monitors~.the HI <br />• aquifer in this area. <br />Water levels in well GB2, which is completed in the Third <br />2-5 <br />
