There were several water level increases observed in 1994 that exceed those expected <br />from natural variations and are responses to mine activities. Wells GE1, GE2 and 81-03a had water <br />level increases which were probably due to a decrease in dewatering at the adjacent underground <br />mine. Well GMP-1's water level increases are most likely due to a reduction in dewatering at Pit <br />A from an average discharge rate of 10.5 gpm to a complete lack of dewatering occurring during <br />1994. The water level rises in well GD3 were due to a decrease in the dewatering rate at Pit D, or <br />were due to the moving of this pit farther from well GD3. Wells GB1, GB2 and GFS also had <br />increases in water-level, probably due predominately to mine activities. Mining is moving farther <br />away from these wells with time. <br />Water-level changes will be discussed in more detail in the following section. <br />• 2.1.2 WATER-LEVEL CHANGES I <br />1 <br />The water-level changes for the period of record dare presented as Figures A-1 through A- <br />39 (Appendix A).
