• 006-AZ-3 (Table 31), new maximum values were recorded for field conductivity, dissolved calcium, dissolved <br />selenium, and dissolved magnesium. At we11006-AW-2 (Table 32) new minimum values were recorded for field <br />pH, and dissolved calcium. New maximum values were recorded for field pH. At we11008-AW-3 (Table 34) a <br />new minimum value was recorded for dissolved manganese. Anew maximum value was recorded for field <br />conductivity. Other monitored water quality parameters returned values at the Fish Creek alluvial wells typically <br />within previously established ranges during 2001. <br />Trout Creek Alluvial Groundwater: Dicing 2001, one Trout Creek alluvial monitoring well (008-AT-1) <br />required monitoring for water levels and field parameters on a monthly basis, and water quality sampling on a <br />quarterly basis. All monitoring requirements were met at this site. Table 35 provides a summary of the 2001 <br />Water Year data collected. Figures 66 and 67 provide graphical representations of water level and field <br />conductivity information to date. One additional well (Jones) required monitoring £or water levels and field <br />parameters on a quarterly basis, and water quality sampling for full suite parameters on an annual basis and <br />sulfate on a quarterly basis. All monitoring requirements were met at this site. Table 36 provides the 2001 data <br />£or tlus well with Figures 68 and 69 providing graphical representations of selected data. <br />Well 008-AT-1 is monitored in conjunction with surface water site 1005. Figure 66 depicts the water level <br />relationship between these two sites. Additionally, at well 008-AT-1 (Table 35) new minimum values were <br />recorded for lab conductivity, and dissolved sodium calcium. At the Jones well (Table 36) new maximum values <br />were recorded for dissolved iron, bicarbonate, and for dissolved manganese <br />• Middle Creek Alluvial Groundwater: Two Middle Creek alluvial wells (AVM-1 and AVM-2) were <br />incorporated into the monitoring network during 1996. Both require monthly monitoring of water levels and field <br />parameters with quarterly water quality sampling. AVM-1 lies in the Middle Creek drainage approximately <br />3500' upstream of the confluence of Middle and Foidel Creeks. AVM-2 lies in the Middle Creek drainage <br />approximately 7500' upstream of AVM-1. These wells were installed in the fall of 1996. Tables 37 and 38 <br />provide summaries of the 2001 Water Year data collected at each site. Tables 37a and 38a provide period of <br />record statistical summaries of collected data at each site. Figures 70 through 73 provide graphical <br />representations of water levels and selected water quality parameters recorded at each site. <br />Data has been collected for these sites for a limited time, although the 2001 data is wmparable to the 2000 water <br />year. Well AVM-1 recorded a new minimum for dissolved sodium, and new maximum for molybdenum. Well <br />AVM-2 recorded a new minimum for dissolved sodium, and new maximmns for dissolved manganese and <br />sulfate. <br />3.3 Surface Water Mouitorint= <br />Monitorin¢/Samnlin¢ Requirements: Technical Revision 38 (TR38, August 2001) requires documentation of <br />the quantity and quality of area stream flows, the discharge from sedimentation control ponds, mine water <br />. discharge, and the quantity and quality of springs. Monitoring sites and sampling frequencies are set forth in <br />TR38, Exhibit 14, Table A, and in CDPS Permits CO-0027154, CO-0036684, and CO-0042161. Site locations <br />are shown on Map 13A, Hydrologic Monitoring Plan of TR38. Table A of TR38 specifies two general <br />9 <br />
