. Wells GF6 and GF11 are completed in the QR aquifer and QR bacldill, <br />respectively. Bacld'ill well GFii is located on the downgradient side of the inactive E pit, <br />while well GF6 is located downgradient of the pit. GFil is 1150 fleet upslope and <br />upgradient of GF6. An overall small rise was observed in well GF6 for 2003 while steady <br />levels were observed in well GFl! (see Figure A-10). The head in well GFli is greater <br />than 17 feet above the head in well GF6. The water levels in the bacld'ill aquifer may be <br />near the fully recovered level from mining. <br />Figure A-li also presents water levels for GP-7 and GP-8, which are located very <br />near the eastern boundary of the PA. They are completed in the l4_M and HI aquifers and <br />may provide undisturbed baseline data for these intervals but could be influenced by mining <br />for the last few years. Water levels in well GP-7 gradually declined in 2003 while a larger <br />decline was observed in well GP-8 for the last three years. Both of these wells are thought <br />to be showing natural responses but could be influenced by the mining that is greater than <br />2200 Feet away. The larger decline in well GP-8 indicates mining may be causing some of <br />this decline. <br />Weil GP-2 (Fgure A-12) is located in a previously und'~sturbed area near the <br />eastern boundary of the PA. Water levels were overall steady in well GP-2 in 2003. These <br />steady water levels followed a rise in 2002 which were preceded by a larger decline. <br />Wells GP-3 and GP-4 are less than 1000 feet downgradient from A pit. Both are <br />flowing wells completed in the HI and IaM aquifers, respectively. Fgures A-13 and A-14 <br />show similar responses in water levels due to changes in precipitation. Water levels in well <br />GP-3 have recovered to above pre-mine levels in this area and show that any depletion of <br />water from upgradient mining has been rep4aoed by recharge to the HI aquifer. The <br />gradual declines in water levels in well GP-3 over the last five years are probaby a function <br />2-7 <br />
