relationship between these two sites. Water quality parameter values depicted on Table 20 are comparable <br />• to other monitored alluvial wells located upstream on both Foidel Creek and Fish Creek. <br />SURFACE WATER MONITORING <br />Foidel Creek: Two surface flow monitoring sites on Foidel Creek in the vicinity of the TCC mine portals <br />and facilities areas are utilized. Site 800 is located upstream of the portal and flows are monitored by the <br />USGS (Station 09243800). Site 8 is located a short distance downstream of the portal area. During 1994, <br />both Foidel Creek surface water monitoring sites generally required montlily flow and field parameter <br />measurements with quarterly water quality sample collection. The monitoring requirements are further <br />described to require 12 flow and field parameter monitoring instances to occur between March and <br />September along with 4 water quality sampling events. The majority of monitoring requirements were <br />fulfilled at these sites in 1994 with the exception that flow and field parameter data collection was not <br />initiated anal April and "make up" monitoring instance was not completed in order to provide the required <br />12 instances. This result is again attributable to miscommunicationbecween personnel during transition of <br />the hydrology monitoring duties. TCC has identified these omissions and will take appropriate steps to <br />ensure compliance with the monitoring program, <br />• Tables 21 and 22 provide summaries of the 1994 Water Year data collected at each site. Tables 21a and <br />22a provide period of record statistical summaries of collected data at each site. Figures 41 through 49 <br />provide graphical representations of water levels and selected water quality parameters recorded at each site. <br />Typical flow patterns were exhibited at these sites with spring runoff periods accounting for the peak flows <br />observed. Runoff magnitudes were somewhat lower than normal during 1994 based upon comparison with <br />previous years data. At both sites, the inverse relationship between flow and field conductivity is evident. <br />Water quality parameter analyses conducted during the year returned values within previously established <br />ranges with the exception of elevated field conducavifies at site 800 evident from July through September <br />and a new maximum total recoverable iron value (1020 ug/1) evident at site 8 in September. The elevated <br />conductivities at site 800 may be at least partially related to the unusually low flows experienced during the <br />year although the overall trend of steadily increasing field conductivity values appears to continue (see Figure <br />45). The elevated iron value at site 8 is a relatively insignificant increase from the previous maximum level <br />of 860 ug/1. Historically, iron values have fluctuated markedly and TCC would anticipate values returning <br />to more normal ranges in the future. <br />Fish Creek: Five surface flow monitoring sites on Fish Creek are utilized. Site 16 is located upstream of <br />the Mine 2 area; site 302 is located downstream of the Fish Creel Borehole mine dewatering site; site 1002 <br />is located approximately 2 miles further downstream and is monitored in conjunction with alluvial well 006- <br />. AW-2; site 27A is located near the Fish. Creek Tipple; and site 1003 is located downstream of the Fish <br />Creek Tipple. During 1994, the Fish Creek surface water monitoring sites generally required monthly flaw <br />-7- <br />
