• monitored water quality parameters returned values at the Fish Creek alluvial wells typically within previously <br />established ranges during 1999. <br />Trout Creek Alluvial Groundwater: During 1999, one Trout Creek alluvial monitoring well (008-AT-1) required <br />monitoring for water levels and field parameters on a monthly basis, and water quality sampling on a quarterly <br />basis. All monitoring requirements were met at this site. Table 35 provides a summary of the 1999 Water Year <br />data collected. Figures 66 and 67 provide graphical representations of water level and field conductivity <br />infonttation to date. One additional well (Jones) required monitoring for water levels and field parameters on a <br />quarterly basis, and water quality sampling for full suite parameters on an annual basis and sulfate on a quarterly <br />basis. All monitoring requirements were met at this site. Table 36 provides the 1999 data for this well with <br />Figures 68 and 69 providing graphical representations of selected data. <br />Well 008-AT-I is monitored in conjunction with surface water site IOOi. Figure 66 depicts the water level <br />relationship between these t+vo sites. Water qualiq~ parameter values depicted on Table 35 are comparable to <br />other monitored alluvial wells located upstream on both Foidel Creek acid Fish Creek. <br />Middle Creek Alluvial Groundwater: Two Middle Creek alluvial wells (AVM-1 and AVM ~) were incorporated <br />into the monitoring network during 1996. Both require monthly monitoring of water levels and field parameters <br />with quarterly water quality sampling. AVM-1 lies in [he Middle Creek drainage approximately 3500' upstream <br />of [he confluence of Middle and Foidel Creeks. AVM ?lies in [he Middle Creek drainage approximately 7500' <br />• upstream of AVM-I. These v+•ells were installed in the fall of 1996. Tables 37 and 38 provide summaries of the <br />1999 Water Year data collected at each site. Tables 37a and 38a provide period of record statistical summaries of <br />collected data at each site. Figures 70 through 73 provide graphical representations of water levels and selected <br />water quality parameters recorded at each site. <br />Due to the limited time that data has been collected for these sites, new minimums and maximums continue to be <br />established for many tested parameters. <br />SURFACE WATER MONITORING <br />Foidel Creek: Three surface Flow monitoring sites on Foidel Creek in the vicinity of [he TCC mine portals and <br />facilities areas are utilized. Site 800 is located upstream of the portal and Flows are monitored by the USGS <br />(Station 09243300). Site 8 is located a short distance downstream of the portal area. Site 900 is located fitrther <br />downstream above the confluence with Middle Creek. Flows at site 900 are also are monitored by the USGS <br />(Station 09243900). During 1999, all three Foidel Creek surface water monitoring sites generally required <br />monthly Flow and field parameter measurements with quarterly water quality sample collection. The monitoring <br />requirements are further described to require 12 flow and field parameter monitoring instances to occur bet+veen <br />March and September along with 4 water quality sampling events. All required monitoring instances were <br />completed during 1999. <br />• <br />7 <br />
