• 2.0 GROUND-WATER LEVELS <br /> Water levels or~prP°-- ave been measured in 39 wells <br /> at Trapper Mine. ^ J^~~ ?, GP3, GP4, and well 81-~3a <br />/W <br /> are flowing wells ~-~, <br />;s on these wells have been <br /> converted to stati ~`~~ above land surface. Well <br /> GD1 is not measured _.~use a pump is installed in <br /> this well. Monitorir.~ wells GD3, GF11 and GLUX-1 were installed in <br /> 1988 and well GMP-1 was installed in 1990. <br /> The locations of these monitoring wells are shown on enclosed <br /> Maps No. 2-1 to 2-3. Wells GD1 and GF1 are completed in the Twenty <br /> Mile Sandstone, while well GF2 is completed below the R coal in the <br /> U aquifer system. Seven wells, GA1, GE1, GD2, GF6, GP1, GP5 and <br /> GP6 are used to monitor the QR aquifer. Wells GA2.

Wells GB2, GC2, P8, 81-03a and GP9 are used to <br /> monitor the Third White Sandstone aquifer. Wells GE3 and P5 are <br /> completed in the Second White Sandstone between the G and F coals, <br /> while Glux-1 is used to monitor the First White Sandstone. Well P3 <br /> is perforated in the Lewis Shale. Four alluvial wells. GC3, P1. J1 <br /> and COY are used to monitor the Flume, Pyeatt and Johnson <br /> alluviums. Wells GF5 and GF7 are completed in the backfill aquifer <br /> in an area where the HI seams were mined. Wells GD3 and GF11 were <br /> completed in backfill aquifers in areas where the QR aquifer was <br />mined. <br /> <br />2-1 <br /> <br />
