support facilities aze monitored. In the Fish Creek Drainage, sites upstream and downstream of the Mine 2 area <br />and the Fish Creek Borehole mine dewatering facilities are monitored. During 1994 on Trout Creek, an <br />additional monitoring site was established downstream of the confluence with Fish Creek. During the 1996 <br />calendar year, monitoring was commenced on two additional Foidel Creek alluvium wells (FO-1 and FO-4) and <br />two additional Middle Creek alluvium wells (AVM-1 and AVM-2). <br />(Foidel Creek Alluvial Groundwater .During 1996, five Foidel Creek alluvial wells (009-S-IQ 001-5-5, 008-AV- <br />2, FO-l, and FO-4) required monitoring for water levels and field parameters on a monthly basis, and water <br />quality sampling on a quarterly basis. An additional well (008-AV-1) required only monthly monitoring for wafer <br />levels and.fi parameters. All monitoring requirements were met at these sites with monitoring wells FO-l <br />d FO-4 com cing in November, 1995. Tables 20 through 25 provide summaries of the 1996 Water Year <br />data collected at each site. Tables 20a through 25a provide period of record statistical summaries of collected <br />data at each site. Figures 35 through 47 provide graphical representations of water levels and selected water <br />quality parameters recorded at each site. <br />Water levels during 1996 remained generally consistent with established ranges and patterns and showed the <br />typical seasonal variability of elevated water levels in the spring. Well 009-5-10 provides data for the alluvial <br />aquifer upgradient from the mine portals. Well 001-S-5 is located just downgradient form the mine portals and <br />surface facilities location and is monitored in conjunction with surface water monitoring site 8. Figure 39 is <br />• indicative of the general relationship between the alluvial groundwater elevations and surface water elevations at <br />these [wo sites. Wells 008-AV-1 and 008-AV-2 are monitored in conjunction with surface water site 304 at a <br />point on Foidel Creek approximately 1000 feet upstream of the confluence of Foidel and Middle Creeks. Water <br />levels in these wells and the stream show the typical seasonal interrelationship of relatively rapid increases and <br />declines associated with spring runoff (Figure 40). The longer term trends in water levels at these sites generally <br />parallel the fluctuations observed in annual streamflows. Wells FO-1 and FO-4 are situated on Foidel Creek <br />approximately overlying the gateroads between the second and third panels to be mined in the EMD. Typical <br />seasonal fluctuations in water levels aze depicted at these sites on figures 44 and 46. <br />Field conductivity measurements in general at well 001-5-5 (1996 average approximately 2000) were again noted <br />to be higher than the upgradient site 009-5-10 (1996 average approximately 1250). Moving downgradient, field <br />conductivities at wells FO-4 and FO-I averaged 3780 and 3410 respectively based on the 1996 data. Further <br />downgradient, field conductivities at well 008-AV-2 are averaging approximately 1750. Conductivity values at <br />well 009-5-10 fluctuated within previously established ranges during 1996 with the exception of an unusually <br />high value recorded in November 1995. The generally increasing field conductivity trend noted in 1994 and 1995 <br />for well 001-S-5 appears evident again in the 1996 data although a marked decline was recorded during the latter <br />half of the year. Field conductivity measurements at wells 008-AV-1 and 008-AV-2 are comparable to <br />measurements at well 001-5-5 and occurred within previously established ranges for these sites.
