<br />the water-level elevation in well GP1 in 1990 has to be natural due <br />to the location of this well. <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 small <br />decline for the three years from mid-1986 to 1989. A small rise <br />was observed in 1990. Changes in water-level elevation in the KLM <br />aquifer near well GP2 are not from mining activities as the nearest <br />mining is approximately two miles away. Water-level elevation data <br />for wells GP1 and GP2 is tabulated in Table A-6. <br />Wells GP3 and GP4 are flowing wells and pressure readings for <br />them have been converted to water-level elevation. Water-level <br />elevation data for well GP3 is tabulated in Table A-6. Figure <br />• A-24 presents the plot of water-level elevation data versus time <br />for well GP3. Water levels for well GP3 significantly declined in <br />late 1987. Water levels continued to decline to late 1989. A <br />water level rise was observed during 1990 in the HI aquifer near <br />this area which may have been caused by mining upgradient. <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. A water <br />level rise has been observe in 1990 in well GP4. <br />~- The water-level elevation versus time plot for well GP5 is <br />,. presented in Figure A-26. :The:levels'in the QR aquifer near well <br />GP5 have been gradually declining since 1985. Water levels in well <br />• GP5 declined approximately 15 feet during 1988 and remained low <br />2-11 <br />
