through 1994. Both wells are interpreted as showing natural responses with a very dampened <br />response and lag to recharge events. Figure A-30 presents the natural variations in water levels for <br />the 3rd White Sandstone aquifer in well GP9. Note that water-level elevations decreased fi~om a <br />high of 6558 ft. in 1986 to a stable level of 6548 R. +/- in 1992-1994. <br />Figure A-31 presents the changes in water-level elevation for alluvial well P 1 located in <br />the Pyeatt drainage north of the PA. This data demonstrates classic seasonal responses, highs in <br />winter/spring and lows in late summerlfall. The overall trend is continuing the decline begun in <br />1988 with a slight recovery observed in 1994. Well P3 is completed in the Lewis Shale outcrop, <br />which is in contact with the Pyeatt alluvium. It demonstrates the same seasonal variations (Figure <br />A-32) as the P 1 well. <br />Wells PS and P8 are located in the E. Pyeatt drainage below A pit. P8 is above PS and <br />within 600' of A pit. They aze completed in the outcrop of the 2nd White Sandstone and 3rd White • <br />Sandstone aquifers, respectively. Each well demonstrates an overal! declining trend ~3Rth <br />superimposed seasonal variations. These wends are interpreted as natural. <br />Water-level elevations for the Johnson and Flume Gulch alluvial wells, Coy and Jl, are <br />presented in Figure A-35 and A-36. Coy shows the natural response of the alluvium to a decline in <br />recharge. The J1 water levels are fairly steady, increasing in early 1994 then declining to slightly <br />lower than the 1993 levels. <br />Well 81-03a is a flowing 3rd White Sandstone well northwest of the PA. Figure A-37 <br />illustrates a decreasing trend with seasonal variations. A net increase of 13.16 ft. from September <br />of 1993 to August of 1994 was reported. This well may be impacted by dewatering at the adjacent <br />underground mine. <br />2-8 <br /> <br />
