• <br />gradually rising until a significant drop in late: 1989, after which <br />levels have continued gradual decline. <br />The GLUX-1 well is used to monitor pze-mine conditions <br />upgradient of the Lux domestic well prior to mining in Browning and <br />Colt pits. Water levels for well GLUX-1 are p^esented on Figure <br />A-38. The last two years show an annual Spring increase and then <br />a decline throughout the remainder of the year. Water levels in <br />well GLUX-1 show an overall declining trend. This decline is <br />probably due to the drier conditions during the last few years that <br />has caused similar, natural declines in several other White <br />Sandstone wells. Well GMP-1 was completed in the HI aquifer in <br />order to monitor ground water conditions do~rngradient of the <br />proposed ash disposal site located just to the south in A pit. The • <br />water level for the past year has remained very stable (Figure A- <br />39). <br />2.2 GROIIND WATER-LEVEL ELEVATION (PIEZOMETRIC IiAP SIIM2lARY) <br />Hydro-Engineering developed three piezometric maps to show the <br />water level flow patterns for the QR, HI and Third White Sandstone <br />aquifers at Trapper Mline. Water levels from the Fall of 1991 were <br />used to develop these maps, which follow this s~:ction. <br />Map No. 2-1 presents the water-level elevations for the QR <br />aquifer. The water-level elevation is rising 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 C, D <br />1 <br />~ 2-14 <br />
