redaimed pits except near the northern (down-dip) end of the mined area, where levels may be limited by the elevation of backfill springs from the northern pits in this area. Significant drawdown has developed adjacent to the p'~ts but the extent of these drawdowns is very limir~d due to the small tiansmissivity in these aquifers. Recovery of the water levels has occurred over a few years as the pits have moved away from an area. Some water levels will likely not recover to their pre-mine levels due to the different flow characteristics developed wdh the backfill aquifer and the controlling of the maximum head by bacldll springs. Variations in natural recharge to the 2nd White Sandstone affect this aquifer greatly. Mining effects on the system have not been detected. The TDS of water in baddill welts GD-3 and GF5 are somewhat higher but similar to those of the native aquifers in these areas. TDS for GF5 is approximately 1.5 times the pre-mine value but is within natural variability of this aquifer. TDS values for badcfill wells GF7 and GFll are much higher than the naturally observed concentrations. TDS in well GF7 has shown some decline from the peak values in the early 1990's and has been fairly steady for the last six years at a slightly lower level. The TDS in well GFil is lower and may have reached its peak in 2001. It is likely that the TDS will remain higher for many years before returning to pre-mine concentrations in these two wells. The change in major constituent concentration in water in these two wells will likely gradually decline as readily soluble constituents are removed. The water quality in QR wells GD-2 and GF6 has been only slightly atTected, if at all, by the upgradient mining. The 2003 TDS values for well GE-1 increased after declining to its pre 1990's values. These changes are within natural variations and may or may not be caused by mining. The remainder of the QR wells are 6-3
