upstream of AVM-l. Well AVM-1 was installed in September 1996. Table 33 provides 1996 data collected <br />from this site. Well AVM-2 was not installed until November. Data will be provided in the next Annual <br />Hydrology Report. <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 areas 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 confluence with Middle Creek. Flows at site 900 are also are monitored by the USGS <br />(Station 09243900). During 1996, 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 between <br />March and September along with 4 water quality sampling events. All required monitoring instances were <br />completed during 1996. <br />Tables 34, 35, and 36 provide summaries of the 1996 Water Year data collected at each site. Tables 34a, 35a, and <br />36a provide period of record statistical summaries of collected data at each site. Figures 64 through 71 and 104 <br />11 through 107 provide graphical representations of water levels and selected water quality parameters recorded at <br />each site. Typical flow patterns were exhibited at these sites with spring mnoff periods accounting for the peak <br />flows observed. Runoff magnitudes were higher than average during 1996 based upon comparison with previous <br />years data. A[ all of these sites, the inverse relationship between flow and field conductivity is evident. Water <br />quality parameter analyses conducted at site 800 during the year returned values within previously established <br />ranges with the exceptions of a new maximum bicarbonate and total alkalinity values and a new minimum SAR <br />figure reported in June, and a new maximum field conductivity noted in August. Analyses results outside of <br />previously established ranges for site 8 include new maximum total recoverable iron and lab conductivity values <br />noted in April, new maximum total recoverable-mercury and total alkalinity values recorded in June, and new <br />minimum SARs documented in June and August. Site 900 data has not been required prior to the 1996 AHR. <br />However, new historical minimum values for lab conductivity and TDS were recorded at this site in April. New <br />maximum magnesium, hardness, and TDS values were subsequently noted in September. <br />Fish Creek:: Five surface flow monitoring sites on Fish Creek are utilized. Site 16 is located upstream of the <br />Mine 2 area; site 302 is located downstream of the Fish Creel Borehole mine dewatering site; site 1002 is located <br />approximately 2 miles further downstream and is monitored in conjunction with alluvial we11006-AW-2; site 27A <br />is located near the Fish Creek Tipple; and site 1003 is located downstream of the Fish Creek Tipple. During <br />1996, the Fish Creek surface water monitoring sites generally required monthly flow and field parameter <br />measurements with quarterly water quality sample collection. The monitoring requirements for all sites except <br />-9- <br />
