• 4.8.2.4 Operational Groundwater Quality <br />Data from numerous water samples of wells GA-1, GA-3, GB-2, GB-5, GD-1, GE-1, GE-2 and GE-3 are <br />given in Table 4.&10 for the operational groundwater monitoring. Data from these same wells prior to <br />mining are given In Table 2.7-22. Map M52 shows the locations of each of the monitoring sites. <br />Results of one analysis of water from the wells GF-1, GF-2 and GF3, and two analyses of samples <br />from wells GBB-1, GBB-2 and GBB-3 are given in the operational water quality Table 4.&10. Data <br />from chemical analysis of samples from two seeps near the old Empire Energy pit are given in Table <br />4.8-10, also. <br />Most parameters have not demonstrated any significant change in concentration since mining has <br />started. The iron concentration in the water from well GA-1 is an exception. Well GA-1 is completed in <br />the O and R coal seams. These seams are being mined appropmatey 2500 feet east of well GA-1 in <br />the Enfield pit. Flow patterns should be mainy to the north in this area of the Q-R aquifer system. <br />• <br />• <br />4-227b <br />P~-~I <br />_ ~Ax l ~._~s9a - <br /> <br />
