the backfill near well GF7. The average yearl;~ water levels for • <br />the past three years have been increasing slightly. Figure A-21 <br />I <br />presents the waterilevel elevation for wel] GE11, which is <br />I <br />upgradient of well GF6. This data indicates that the water levels <br />in the backfill of this area fluctuate seasonally due to recharge. <br />Figure A-22 presents the water-level elevation data for well <br />GP1. Well GP1 was a flowing well but the water levels declined to <br />below the top of the casing. This large decli~ie for well GP1 in <br />1990 and 1991 has to be natural due to the locat:.on of this well in <br />relation to mining. ~ <br />The water-level elevations for cell GP2 i.s shown on Figure <br />A-23. Levels have shown a small decline durir~.g the three years <br />from mid-1986 to 1989. A small rise was observed in 1990, and in . <br />1991 the water level 'returned to the 1989 value. These changes in <br />water-levels for the KLM aquifer near well GP2 a.re not from mining <br />activities since the nearest mining is approximately two miles <br />away. Water-level ',elevation data for welly GP1 and GP2 is <br />tabulated in Table A-6 (page A-51). Water-level elevation data for <br />well GP3 is tabulated in Table A-6 also. Figure A-24 presents the <br />plot of water-level elevation data versus time f~~r well GP3. Water <br />levels in this well significantly declined in late 1987. Water <br />levels continued to decline to late 1989. A water level rise was <br />observed during 1990 through the first half cif 1991 in the HI <br />aquifer near this area, which may have been ca~ised by upgradient <br />mining. <br /> <br />2-10 <br />
