chromium, copper, lead, mercury, nickel, selenium, and silver for WCSW -01 were less <br />than the analytical detection limits. Trace metal data also are provided in Table 4 -6. <br />4.1.3.4 MLE2 Impacts to Surface Waters <br />No impacts are anticipated to the surface water resources in Wilson Creek drainage <br />(including Theresa Gulch and Bateman Creek) due to MLE2. Flows and water quality <br />conditions are expected to remain consistent with historic measurements. Water quality <br />conditions for selected parameters at T -3 may continue to show improvements from the <br />Independence Tailings closure project in 2007. <br />The flow and water quality conditions in the surface waters of Wilson Creek will <br />continue to be monitored by T -1, T -2, T -3, WCSW, BCSW, and WCSW -01. <br />4.1.4 Ground Water <br />4.1.4.1 Monitoring Program <br />Ground water conditions in the Wilson Creek drainage are assessed by three monitor <br />wells (Figure 2 -2). All the monitor wells are located in the Bateman Creek drainage. <br />The monitor wells are designated WCMW -2, WCMW -3, and WCMW -6. WCMW -2 is <br />completed in the alluvium /shallow bedrock. WCMW -3 and WCMW -6 are completed in <br />the bedrock. All the monitor wells are located in the granites adjacent to the Diatreme. <br />Field parameters and water quality samples are collected quarterly at WCMW -3 and <br />WCMW -6 and analyzed for the parameters listed in Table 3 -2. Field parameters and <br />water quality samples also are collected quarterly at WCMW -2 and analyzed for the <br />parameters listed in Table 3 -2. Pressure transducers were installed in WCMW -2, <br />WCMW -3, and WCMW -6 in July of 2011 to more frequently (4x/day) monitor the water <br />level. The data are periodically downloaded and compiled. <br />4.1.4.2 Data <br />The period of record and compiled field and water quality data (number of <br />measurements, less than detection events, maximum value, minimum value, average <br />value, standard deviation, and median value) for the monitor wells WCMW -2, WCMW- <br />3, and WCMW -6 are provided in Tables 4 -7, 4 -8, and 4 -9, respectively. Figure 4 -3 <br />shows the hand level measurements and the Hobo data for WCMW -2, WCMW -3, and <br />2 "Alluvium" refers to soil, colluvium, and alluvium materials in the subsurface. <br />3 The pressure transducer is the Hobo model manufactured by Onset, Inc. This transducer is the only model used by CC &V for <br />ground water monitoring. <br />'Cripple Creek & Victor Gold Mining Company <br />Cresson Project Hydrologic Evaluation for Mine Life Extension 2 <br />8 <br />
