NEWMONT <br /> GOLDCORR <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 <br /> of these wells are monitored on at least a quarterly basis at most locations with some locations <br /> sampled more frequently. Groundwater data are submitted to DRMS on a regular basis and are <br /> provided in Appendix 6 of this Amendment 13 permit. <br /> Groundwater monitoring information includes at least five successive calendar quarters of data <br /> for existing wells, which have been summarized for approximately 27 monitoring wells in the <br /> Cresson Project area, excluding Grassy Valley. Another 29 wells have been installed and <br /> monitored in Grassy Valley to provide overall water quality and elevation. As noted in prior <br /> submittals, deep diatreme groundwater is not developed for use in this area and is not anticipated <br /> 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 <br /> locations: downgradient of the AGVLF in Arequa Gulch (CRMW-3A, CRMW-3B, CRMW-3C, <br /> CRMW-5A, CRMW-5B, CRMW-5C, and CRMW-5D) and Wilson Creek (WCMW-3 and WCMW- <br /> 6); downgradient of the SGVLF in Squaw Gulch (SGMW-5, SGMW-6A, SGMW-6B, SGMW-7A, <br /> and SGMW-7B); downgradient of the East Cresson Mine area at two locations in Vindicator Valley <br /> (VIN-2A and VIN-21B) and five locations in Grassy Valley (GVMW-8A, GVMW-8B, GVMW-22A, <br /> GVMW-22B, and GVMW-25); downgradient of the North Cresson Mine area in Poverty Gulch at <br /> three locations (PGMW-2, PGMW-3, and PGMW-4); and downgradient of the External Storage <br /> Pond ("ESP") in Arequa Gulch (ESPMW-1). <br /> A list of groundwater monitoring wells is provided in Table G-3, and parameters analyzed are <br /> listed in Table G-4. <br /> Table G-3: Groundwater Monitoring Sites <br /> FrequencySite Number Location Monitoring <br /> CRMW-3A <br /> CRMW-3B Arequa Gulch — Quarterly <br /> Downgradient <br /> CRMW-3C <br /> Cripple Creek&Victor Gold Mining Company Exhibit G <br /> Cresson Project Amendment 13 <br /> 9 <br />
