Environmental Protection Plan, Schwartzwalder Mine 12-1 <br />J <br />• <br />r? <br />?J <br />12. WATER QUALITY MONITORING PLAN <br />A Water Quality Monitoring Plan for surface water and groundwater is in effect at the Schwartzwalder <br />Mine in compliance with License Condition 23.0 and 23.2 of RML 369-03S; Amendment 08. Table 12-1 <br />summarizes the sampling stations and sampling frequency in surface water, while Table 12-2 lists the <br />active groundwater monitoring wells and sampling stations. The Monitoring Plan is also attached. <br />Surface water monitoring is conducted monthly at five sampling locations on Ralston Creek (Table 12-1). <br />Samples are analyzed for a limited analytical suite (dissolved uranium, suspended uranium and radium- <br />226) or for an extended analytical suite. The extended analytical suite includes 30 parameters (major ions, <br />physical properties, total metals, dissolved metals and dissolved radionuclides). Groundwater monitoring is <br />conducted quarterly at ten monitoring wells and one domestic well (Table 12-2). Samples are analyzed for <br />a limited analytical suite (dissolved uranium) or for an extended analytical suite. The extended analytical <br />suite in groundwater is the same as that used for surface water extended analysis (30 parameters, including <br />major ions, physical properties, total metals, dissolved metals and dissolved radionuclides). One or two <br />wells are sampled for the extended analytical suite each quarter. In addition, samples from the domestic <br />well are analyzed quarterly for the limited analytical suite (dissolved uranium, suspended uranium, and <br />radium-226). <br />Additional samples may be collected at surface water station SW-ARH (above Red Hill) and at Sump 1 and <br />Sump 3, although monitoring at these stations is not required under the currently approved monitoring plan. <br />Water samples from the sumps are typically analyzed for dissolved uranium, only. Water quality in the <br />flooded mine shaft is also typically sampled quarterly, and analyzed for the extended analytical suite. <br />Table 12-1.
