• have been collected at these sites. However, none of these values fell outside the typical historical range of other wells in this aquifer. ,~ / Fish Creek Sandstone: During 2000, two Fish Creek Sandstone wells (91M001 and 91M004) required monitoring for water levels on a quanerly basis. Monitoring requirements were met during the 2000 Water Year at these wells. An additional well (Ashley required semi-annual monitoring for water levels and field parameters,-and annual water qua`~ty sampling. Tables 21, 22, and 23 provide summaries of the 2000 Water Year data collected at each site. Figure 40 provides graphical representation of the period of record water levels measured a[ sites 91M001 and 91M004. The seasonal fluctuation apparent in well 91M001 in prior years seems to have stabilized in 2000. Water levels at the Ashley well (Figure 41) dropped appreciably after subsidence, but are continuing to recover in 2000. Field measurements and water quality parameters for the Ashley well are provided on Table 23. This well established many new maximum and minimum values for tested parameters in 2000, due to the limited period for which values have been collected. However, none of these values are anomalous relative to the typical historical range of sandstone aquifers in this area. ALLUVIAL GROUNDWATER MONITORING Alluvial deposits containing groundwater are monitored in the Foidel Creek, Fish Creek, Trout Creek and Middle Creek drainages. In the Foidel Creek drainage, sites both upstream and downsVeam of the TCC portals and • support facilities are monitored. In the Fish Creek Drainage, sites upstream and downstream of the Mine 2 area and the Fish Creek Borehole mine dewatering facilities are monitored. Foidel Creek Alluvial Groundwater: During 2000, five Foidel Creek alluvial wells, 009-5-10, 001-5-5, 008-AV- 2, FO-l, and FO-4, required monitoring for water levels'and field parameters on a monthly basis, and water quality sampling on a quanerl~asis. An additional well, 008-A V-I er quired monthly monitoring for only water levels and field parameters. All monitoring requirements were met at these sites. Tables 24 through 29 provide summaries of [he 2000 Water Year data collected at each site. Tables 24a through 29a provide period of record statistical summaries of collected data at each site. Figures 43 through 55 provide graphical representations of water levels and selected water quality parameters recorded at each site. Water levels during 2000 remained generally consistent with established ranges and patterns and showed the typical seasonal variability of elevated water levels in the spring. Well 009-S-]0 provides data far the alluvial aquifer upgradient from [he mine portals. Well 001-5-5 is located just downgradient form the mine portals and surface facilities location and is monitored in conjunction with surface water monitoring site 8. Figure 47 is indicative of the general relationship between the alluvial groundwater elevations and surface water elevations at these two sites. Wells 008-AV-] and 008-AV-2 are monitored in conjunction with surface water site 304 at a point on Foidel Creek approximately ]000 feet upstream of the confluence of Foidel and Middle Creeks. Water levels in these wells and the stream show the typical seasonal interrelationship of relatively rapid increases and declines associated with spring runoff (Figure 48). The longer-term trends in water levels at these sites generally parallel the fluctuations observed in annual stream Flows. Wells FO-1 and FO-4 are situated on Foidel Creek 5
