Wells GP-5 and GP-6 are both completed in the QR aquifer. GP-5 is immediately • <br /> downgradient of A pit and GP-6 is immediately upgradient of the pit. Water-level data is <br /> tabulated in Table A-1 in Appendix A. Figures A-15 and A-16 present water level versus <br /> time plots. Both plots are similar, with an overall rising trend observed during the last four <br /> years. These responses are interpreted to be due to increased in recharge due to the <br /> Increased precipitation. The large distance to active QR mining, with the exception of the <br /> F pit mining that began in 1997, indicates that this water-level rise is a natural rise from <br /> increased recharge. <br /> Figure A-15 presents the change in water-level elevation for alluvial well P-1, <br /> located in the Pyeatt drainage north of the PA. This data demonstrates classic seasonal <br /> --responses, highs in winter/spring and lows in late summer/fall. An overall increasing trend <br /> occurred beginning in 1992 and has been followed by a gradual decline in the last one and • <br /> one-half years. Well P-3 is completed in the Lewis Shale outcrop, which is in contact with <br /> the Pyeatt alluvium. It demonstrates the same seasonal variations (Figure A-15) as the P-1 <br /> well. <br /> Water-level elevations for the Johnson Gulch alluvial well 3-1 are also presented <br /> in Figure A-15. The 3-1 water levels have remained fairly steady in 1998. <br /> 2.2 GROUND WATER-LEVEL ELEVATION (PIEZOMETRIC MAP SUMMARY) <br /> Hydro-Engineering developed three piezometric maps to show the water level <br /> flow patterns for the QR, HI and 3rd White Sandstone aquifers at Trapper Mine. Water <br /> levels from the Fall of 1998 were used to develop these maps. <br /> 2-8 <br />
