2.6-1 <br />2.6.1 Ground Water Monitoring_ <br />A water quality monitoring program as been established to monitor the effects of the <br />McClave Canyon and Munger Canyon mines on ground waterin the area. The groundwater <br />monitoring program will consist of the following observations, measurements and sampling: <br />1. Quarterly monitoring of wells GW-2, GW-3, GW-4, GW-6 and GW-8 for <br />Static Water Level, pH, Temperature, and Specific Conductance. <br />2. Water quality sampling of mine water discharges as required by NPDES <br />and CDOH permit. <br />3. Monitoring of all non-seep inflows into to mine to include source, quantity, <br />duration and quality (pH, Electrical Conductance, and 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 groundwater monitoring shall be submitted to the Division .. <br />immediately after data collection and analysis. Results of additional monitoring will be <br />submitted to the Division in an annual hydrological report. The annual report will detail <br />inflows, discharges and consumption of water within the mine and shall be structured around <br />the normal 'tivater year" (October 1 through September 30). <br />Water samples will be collected with a bailer after the depth to water table has beeri <br />measured. All monitoring wells shall be pumped at lease once a year and prior to sample <br />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 been sampled as <br />required prior to the construction of the Munger Canyon Waste Rock Pile. Water quality <br />samples shall be taken and water levels established quarterly. Analysis will be for the above <br />noted parameters. <br />On March 20, 1984, the Division approved a revision to sample GW-6 in Munger Canyon only <br />during the period of temporary cessation. Since GW-6 has been dry since installation, well <br />GW-3 will be substituted and monitored quarterly for Static Water Level, pH, Temperature, <br />and Specific Conductance. <br />Mu VOLUMEI 1.9-96 <br />
