<br />Cripple Creek & Victor Gold Mining Company Exhibit G Cresson Project Amendment 13 9 <br />Aluminum (mg/L) Dissolved Iron (mg/L) Total Recoverable Zinc (mg/L) Dissolved <br />Cyanide [WAD] Lead (mg/L) Total Recoverable <br />3.2 Groundwater Monitoring <br />There are currently 53 active wells used for various monitoring activities at the site. Twenty-seven of these wells are monitored on at least a quarterly basis at most locations with some locations sampled more frequently. Groundwater data are submitted to DRMS on a regular basis and are provided in Appendix 6 of this Amendment 13 permit. <br />Groundwater monitoring information includes at least five successive calendar quarters of data for existing wells, which have been summarized for approximately 27 monitoring wells in the Cresson Project area, excluding Grassy Valley. Another 29 wells have been installed and monitored in Grassy Valley to provide overall water quality and elevation. As noted in prior submittals, deep diatreme groundwater is not developed for use in this area and is not anticipated to be developed for use in the future in light of the overall lack of groundwater. <br />Groundwater quality and depth to groundwater is monitored on a quarterly basis at the following locations: downgradient of the AGVLF in Arequa Gulch (CRMW-3A, CRMW-3B, CRMW-3C, CRMW-5A, CRMW-5B, CRMW-5C, and CRMW-5D) and Wilson Creek (WCMW-3 and WCMW-6); downgradient of the SGVLF in Squaw Gulch (SGMW-5, SGMW-6A, SGMW-6B, SGMW-7A, and SGMW-7B); downgradient of the East Cresson Mine area at two locations in Vindicator Valley (VIN-2A and VIN-2B) and five locations in Grassy Valley (GVMW-8A, GVMW-8B, GVMW-22A, GVMW-22B, and GVMW-25); downgradient of the North Cresson Mine area in Poverty Gulch at three locations (PGMW-2, PGMW-3, and PGMW-4); and downgradient of the External Storage Pond (“ESP”) in Arequa Gulch (ESPMW-1). <br />A list of groundwater monitoring wells is provided in Table G-3, and parameters analyzed are listed in Table G-4. <br />Table G-3: Groundwater Monitoring Sites <br />Site Number Location Monitoring Frequency <br />CRMW-3A <br />Arequa Gulch – Downgradient Quarterly CRMW-3B <br />CRMW-3C
