variations. A net decline of 12.69 ft. from September of 1992 to <br />August of 1993 was reported. This well may be impacted by <br />dewatering in the adjacent underground mining permit. It should be <br />noted that wells completed in this interval at undisturbed sites <br />show a similar overall decreasing. trend. <br />The Glux-1 well water level plot (Figure A-38) is very similar <br />to the nearby 81-03a well. The Glux-1 is completed in the 1st <br />White Sandstone aquifer; 81-03a in the 3rd White. It is shallower <br />than the 81-03a, which may account for the increase in the spring <br />of 1993. <br />Well GMP-1 was completed in the HI aquifer to monitor ground- <br />water conditions downgradient of the ash disposal site immediately <br />south of A pit. Water levels have continued the increase begun in <br />1992, up 4.5 ft. during this report period. <br />2.2 GRODND WATER-LEVEL ELEVATION (PIEZOMETRIC MAP SQl4lARY) <br />Hydro-Engineering developed three piezometric maps to show the <br />water level flow patterns for the QR, HI and 3rd White Sandstone <br />aquifers at Trapper Mine. Water levels from the fall (August) of <br />1993 were used to develop these maps, which follow this section. <br />Map No. 2-1 presents the water-level elevations for the QR <br />aquifer. The water-level elevation is presented for the QR wells: <br />GA1, GD2, GE1, GF6, GP1, GP5, and GP6 and backfill wells GD3 and <br />GF11. The ground-water flow in the QR aquifer is mainly to the <br />north. Mining has only affected the QR aquifer close to the D and <br />E pits by causing drawdowns very near the pit edges.
