• Wells GA-1 and GA-2 were selected as monitoring wells at the GA Bile to monitor the Q and R seams, <br />and SS above ~ aquifers. These wells were removed by the advancement of Dertinger Pit in 1995. <br />Wells GA-3 and GA-4 were not included in the monitoring program because they are completed in the Q <br />and R aquifer also. Wells GB-2 and G8-5 are used to monitor the SS above H seam, and H and 1 seam <br />aquifers. Well GB-1 monitors water level only because well GF-3, which is nearby, monitors close to the <br />same strata. Wells GC-1 and GC-3 are monitored to obtain adtlilional pre-mine water levels. Fluctuation <br />of constituents far away from any mining will be of interest. <br />Well GD-1 was dropped as a sample well with the construdion,.of GD-1(2)(see MR-115). The GD-1 (2) <br />well currently supplies Trappers domestic water needs wHh GD•t the approvetl domestic backup well. All <br />three of the GE wells are proposed for monitoring because of their strategic location. These three wells <br />are located down gradient of the Deninger, Colt and oki Empire Energy pits. Wells GE-1, GE-2 and <br />GE-3 are completed in aquifers of the Q and R, H and I, and F coal seams and below SS, respectively. <br />The GF-1, GF-2 and GF-3 wells are perforated in the Twenty-Mile Sandstone, U Complex and K-L-M <br />Complex aquifers. All three of these wells are proposed for monitoring. Wells GBB-1, GBB-2 and GBB-3 <br />were used as monitoring wells until July 1, 1987. These wells were then abandoned and an Empire <br />Energy well (Empire Well 81-03a) is now used. <br />Ashmore Pit shortens and lengthens w8h various cuts as it progresses east. Any ground water <br />recharged to the spoils can be expelled to accumulate in the northern end of the cut that extends the <br />• farthest north. In order to monitor groundwater for utility waste effects, a series of wells have been <br />installed or proposed. <br />Well GF-5 was established (1984) in regraded spoils at the north end of Ashmore Pit in No-Name <br />Drainage. Well GF-7 was installed in regraded spoil at the north end of Ashmore Pit in 1987. <br />• 4248 <br />Pe-4 <br />ft?RY 1 3 1998 <br />
