monitoring of this well does not produce data of value and should be discontinued. Well B-5 was measured and drv in Decenber, 1992. 'This data was omitted fran the AEi12. B-6': Well B-6 has been dry since it was installed in 1982. Continued monthly monitoring of this well does not produce data of value arcs should be discontim~ed. Well B-6 was moaci~red and drv in Decenber. 1992. This data was omitted from the AHR. B-7: Well B-7 provides consistent water level ++~a~~rements and a sampling point to detect groundwater impacts stemming from the East Mine facilities.

Continued monthly monitorirg of this well does not produce data of value and should be discontinued. Well B-8 was measured and drv in December. 1992. This data was omitted from the AHR. SM-5: Well SM-5 is located outside the potential subsidence zone. No mining which could be reasonably e~ec-ted to affect this shallow aquifer has taken place to date. A sufficient water quality database has been established to define the pre-mining water quality at this location. Therefore, only one full suite analyses was conducted during 1992. well: pH = 7.7; EC = 690; T~ C° = 15. Monitories frequency at this location should be reduced as no subsidence impacts can reasonably be anticipated to effect this location. SM-6: Well SM-6 is located outside the potential subsidence zone. No mining which could be reasonably e~ec:ted to affect this shallow aquifer has taken place to date. A sufficient water quality database has been established to define the pre-mining water quality at this location. Therefore, only one full suite analyses was cordttcted during 1992. wall: off = 7.8: EC = 630; TLS C° = 13. Monitorir-g frequency at this location should be reduced as no subsidence impacts can reasonably be anticipated to effect this location. ShI-7: Well SM-7 is located outside the potential subsidence zone. No mining which could be reasonably expected to affect this shallow aquifer has taken place to date. A sufficient water quality database has been established to define the pre-mining water quality at this location. 12 fanalyses coDV enclosed).
