• 2.6 Ground Water Monitorino <br />A water quality monitoring program has been established to monitor the effects <br />of the McClane Canyon and Munger Canyon mines on ground water in the area. The <br />ground water monitoring program will consist of the following observations, <br />measurements and sampling: <br />1. Quarterly monitoring of wells GW-1, GW-3, and GW-6 for Static Water <br />Level, pH, Temperature, and Specific Conductance. <br />2. Water quality sampling of mine water discharges as required by CDPS <br />permit. <br />3. Monitoring of all non-seep inflows into the mine to include source, <br />quantity, duration and quality (pH, Electrical Conductance, and <br />Temperature). <br />4. Monitor quantities of water discharged from the mine, consumed in the <br />mine, and imported for use in the mine. <br />Results of the quarterly ground water monitoring shall be submitted to the <br />Division immediately after data collection and analysis. Results of additional monitoring <br />will be submitted to the Division in an annual hydrological report. The annual report will <br />• detail inflows, discharges and consumption of water within the mine and shall be <br />structured around the normal "water year" (October 1 through September 30). <br />Water samples will be collected with a bailer after the depth to water table has <br />been measured. All monitoring wells shall be pumped at least once a year and prior to <br />sample collection with an air lift or a bailer. <br />The monitoring well GW-6, as shown on Figure 2.3-5, was installed and has <br />been sampled as required prior to the construction of the Munger Canyon Waste Rock <br />Pile. Water quality samples shall be taken and water levels established quarterly. <br />Analysis will be for the above noted parameters. <br />On March 20, 1984 the Division approved a revision to sample GW-6 in Munger <br />Canyon only during the period of temporary cessation. Since GW-6 has been dry since <br />installation, well GW-3 will be substituted and monitored quarterly for Static Water <br />Level, pH, Temperature and Specific Conductance. <br />Permit Renewal <br />2-30 <br />09/03 <br />
