• Well 81-03a is completed in the Third White Sandstone. <br /> Figure A-37 presents the water-level elevation data for well 81- <br /> 03a. Well head pressures for flowing well 81-03a were converted <br /> to water-level elevation . Water levels presented for the <br /> monitoring period have considerable scatter. <br /> The Glux-1 well was completed in the First White Sandstone <br /> in September 1988 in order to monitor pre-mine conditions <br /> upgradient of the Lux domestic well prior to mining in Browning <br /> and Colt pits. Water levels for well Glux-1 are presented on <br /> Figure A-38. <br /> 2.2 GROUND WATER-LEVEL ELEVATION <br /> • Three piezometric maps were developed to show the water level <br /> flow patterns for the OR, HI and Third White Sandstone aquifers <br /> at Trapper Mine. Water levels from the Fall of 1989 were used in <br /> the development of these maps. <br /> Map No. 2-1 presents the water-level elevations for the OR <br /> aquifer. The GP series wells that are shown on this map are the <br /> wells installed for the eastern portion of the permit . The <br /> water-level elevation is shown for the OR wells, GA1 , GD2, GE1 , <br /> GF6, GP1 , GPS and GP6 and backfill wells GD3 and GF11 . The <br /> ground-water flow in the OR aquifer is mainly to the north. <br /> Mining has affected the OR aquifer only close to the D and E pits <br /> by causing drawdowns very near the pit edges. The installation <br /> of backfill wells GD3 and GF11 have defined the depressed <br /> • elevations in the backfill areas. The backfill water levels will <br /> 2-14 <br />
