1/ mine inflow water encountered in the mine workings east of the mains. The inflow rates documented during [he 1996 mine inflow survey are far below those predicted for this area of the mine. Historical mean flow rate information for sites 109 and 115 is presented on Table 50. During 1996, the mean discharge rate for these sites decreased again relative to recently recorded figures due to the previously discussed pump malfunction and the completion of mining in the Southwest Mining District which led to the cessation of site 115 discharges. In 1997, site 109 discharges are anticipated to cease as well as this water will also be routed into the old mine workings west of the mains rather than pumped to the surface. SUMMARY No significant unexpected hydrology impacts attributable to the activities or developments at the Foidel Creek Mine are observed to have occurred during the 1996 Water Year. The previously noted declining water level trend in Wadge Overburden well 91M006 appears to have continued during 1996 after stabilizing levels were noted during 1995. This trend may be related to localized dewatering of the formation as a result of mining activities in the vicinity. A marked decline in water level which co//rresponds temporally with development mining in the 9RT and 10 RT gateroads was noted to occur in wells 93~M001 and 93M003. No significant water quality degradation is noted for the Wadge Overburden formation as //a result of evaluating data collected during 1996. Water levels in the monitored Twentymile Sandstone wells remained comparable to previously collected data and stable. No significant water quality influences are noted to be evident in field data obtained during 1996. Water quality monitoring at wells FBR-11-B and FBR-2 was initiated in 1996. Localized dewatering of the Trout Creek Sandstone appears evident in the vicinity of well 001-83-106 although levels remain stable. The declining water level trend continues to be apparent at well 001-83-107. Slight declines were also noted at wells FCM#2 and 95M001 during the year. All of these declines may be attributable to the pumping of well 001-83-106. Well monitoring efforts at 95M001 during 1996 yielded water levels comparable to those previously documented at well FCM#2. Water quality characteristics recorded at this site are also comparable to those previously defined for well FCM#2. The water levels returned by this site and by well FCM#2 during 1996 are noted to be markedly lower than levels previously returned from well 006-83-48C. No inflows from the Trout Creek formation into the mine workings have been encountered to explain this difference in potentiometric surface or to suggest that dewatering of the formation is directly attributable to mining activities. No readily apparent water quality impacts associated with mining are noted for the Trout Creek Sandstone aquifer based upon data collected during 1996. U _,5_
