pit near well GF-4. The overall flow regime in this aquifer is northerly, similar to that <br /> observed in 1998 (see Hydro-Engineering, 1999). The ground-water gradient between the <br /> backfill aquifer and the un-mined HI aquifer downgradient is relatively flat as it is in the QR <br /> backfill. The contours in the HI aquifer have also been changed on the east side of the <br /> active A pit. <br /> The 3rd White Sandstone aquifer water-level elevations are presented on Map <br /> No. 2-3. Wells GB-2, GC-2, GE-3, P-8, 81-03A, and GP-9 were used in the development of <br /> this map. Flow direction in the 3rd White Sandstone is mainly toward the north, as <br /> expected. Data from wells GE-3 and 81-03A indicate that the 3rd White Sandstone water <br /> flows toward the west between these two wells and probably toward a discharge to an <br /> adjacent aquifer or to the surface. The 1999 contours are very similar to those observed <br /> over the last few years. • <br /> • <br /> 2-10 <br />
