wells GF5 and GF7, were used in the development of this map. Wells <br />GF5 and GF7 are completed in the backfill in the area where the H <br />and I coal seams were mined. Flow in the HI aquifer has been <br />changed mainly near the A, D, and E pits and the former B and C <br />pits, now recovering. The overall flow regime in this aquifer is <br />northerly, similar to that observed in 1992 (see Hydro-Engineering, <br />1993). The ground-water gradient between the backfill aquifer and <br />the unmined HI aquifer downgradient is relatively flat as it is in <br />the QR backfill. The main change in the HI contours is near the <br />active A pit in the Pyeatt drainage. <br />The 3rd White Sandstone aquifer water-level elevations are <br />presented on Map No. 2-3. Wells GB2, GC2, GE3, P8, 81-03a, and GP9 <br />• were used in the development of this map. Flow direction in the <br /> 3rd White Sandstone is mainly toward the north, as expected. <br />Additional data from wells GE3 and 81-03a indicate that the 3rd <br />White Sandstone eater flows toward the west between these two wells <br />and probably toward a discharge to an adjacent aquifer or to the <br />surface. <br /> <br />2-13 <br />
