The water-level changes for the HI aquifer have generally been influenced less by <br />slightly less than average recharge during the last sbc years. The mining upgradient of HI <br />wells G&5 and GF4, which occurred several years ago, has been long enough in the past <br />to allow water levels to fully recover. The water levels in these HI aquifer wells seem to be <br />varying only Blighty with changes in recharge rates. Water levels in these two wells were <br />fairly steady in 2003 with the slightly bekwv normal precipitation. Water levels are not likey <br />to ever rewver to their pre-mine level in well GB-5. The elevation of the backfilt springs <br />likey limits the head buildup in the backfill aqu""fifer, which, in tum, limits the maximum head <br />in the downgradient coal aquifer. Similar water-level responses are being observed in the <br />two baddill equivalent HI aquifer welts GF5 and GF7, Water levels seem to have reached <br />recovered levels in these two wells. The development of baddill springs may limit the <br />maximum water level in some of these areas of the A pit. <br />The water levels in the three GE wells stabil¢ed in approximatey 1990. This is <br />thought to be due to the length of time since dewatering stopped at the adjacent <br />underground operation. Gradualy declining water levels were observed in these three wells <br />with the below normal precipdation. <br />Water levels in the baddill areas are depressed and are not likey to ever recover to <br />pre-mine levels except near the northern end of the mine area. Map 2-1 shows that the <br />levels in the backfill and downgradient aquifers are similar. Well pairs GD-3 & GD-2 and GF <br />11 & GF6 present water levels that are very similar in water-level elevation for the backfill <br />and downgredient QR aquifer well. Mining is significantly increasing the permeability of the <br />baddill aquifers which is a benefit relative to potential yields from the aquifer. The <br />increased permeability will likey not allow water levels to recover to pre-mine levels in the <br />6-2 <br />
