• stabilizing as values for 1988 showed little change. The HI <br /> aquifer in this area should not have been affected by mining in <br /> 1988. <br /> Figure A-25 presents the water-level elevation data for well <br /> GP4, which is completed in the KLM aquifer. Data prior to 1988 <br /> shows a great deal of variance with the third quarter of 1987 <br /> being significantly lower than previous measurements. Water- <br /> level elevations for 1988 have remained steady. <br /> The water-level elevation versus time plot for well GPS is <br /> presented in Figure A-26. The levels in the OR aquifer near well <br /> GP5 have been fairly steady through September 1987. Water levels <br /> in well GPS declined approximately 15 feet during 1988. This <br /> response reflects the drought conditions of 1988. Well GPb is <br />• completed in the OR aquifer and is located approximately 4700 <br /> feet south of well GPS. Water-level elevation versus time is <br /> presented in Figure A-27. Overall water levels have dropped <br /> slightly in the OR aquifer in this area since September 1987, but <br /> the decline is very small compared to the change in well GPS. <br /> Water levels in the OR aquifer at well GPb must not be as <br /> sensitive to changes in recharge as they are at well GPS. Water- <br /> level data for wells GP4, GPS and GP6 are presented in Table A-7. <br /> Well GP7 is completed in the HI aquifer at the easternmost <br /> side of the Trapper Mine permit boundary. Water-level elevations <br /> versus time for well GP7 are presented on Figure A-28. Levels <br /> have shown fairly little change since 1985. The September 1985 <br /> value is significantly higher probably due to drilling fluid left <br />. in the well after completion before water levels could stabilize. <br /> Figure A-29 presents the water-level elevation versus time <br />2-10 <br />
