• conductivity information to date. One additional well (Jones) required monitoring for water levels and field <br />pazameters on a quarterly basis, and water quality sampling for full suite parameters on an annual basis and <br />sulfate on a quarterly basis. Noting that 2nd Quarter sampling was delayed until the first week of April, all <br />monitoring requirements were met at this site. Table 32 provides the 1997 data for this well with Figures 60 and <br />61 providing graphical representations of selected data. <br />Well 008-AT-1 is monitored in conjunction with surface water site 1005. Figure 58 depicts the water level <br />relationship between these two sites. Water quality parameter values depicted on Table 31 are comparable to <br />other monitored alluvial wells located upstream on both Foidel Creek and Fish Creek. <br />Middle Creek Alluvial Groundwater: Two Middle Creek alluvial wells were incorporated into the monitoring <br />network during 1996. Both will require monthly monitoring of water levels and field parameters with quarterly <br />water quality sampling. Wells AVM-1 and AVM-2 are located on the Middle Creek drainage. AVM-1 lies <br />approximately 3500' upstream of the confluence of Middle and Foidel Creeks. AVM-2 lies approximately <br />7500' upstream of AVM-1. These wells were installed in the fall of 1996. <br />Due to the limited time that data has been collected for these sites, new minimums and maximums were <br />established for most tested parameters. <br />SURFACE WATER MONITORING <br />Foidel Creek: Three surface flow monitoring sites on Foidel Creek in the vicinity of the TCC mine portals and <br />facilities azeas are utilized. Site 800 is located upstream of the portal and flows are monitored by the USGS <br />(Station 09243800). Site 8 is located a short distance downstream of the portal area. Site 900 is located further <br />downstream above the wntluence with Middle Creek. Flows at site 900 are also are monitored by [he USGS <br />(Station 09243900). During 1997, all three Foidel Creek surface water monitoring sites generally requtred <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 pazameter monitoring instances to occur between <br />March and September along with 4 water quality sampling events. All required monitoring instances were <br />completed during 1997. <br />Tables 34, 35, and 36 provide summaries of the 1997 Water Year data collected at each site. Tables 34a, 35a, <br />and 36a provide period of record statistical summaries of collected data at each site. Figures 64 through 71 and <br />104 through 107 provide graphical representations of water levels and selected water quality parameters <br />recorded at each site. Typical flow patterns were exhibited at these sites with spring runoff periods accounting <br />for the peak flows observed. Runoff magnitudes were higher than average during 1997 based upon comparison <br />with previous year's data. At all of these sites, the inverse relationship between flow and field conductivity <br /> <br />-8- <br />
