- Turbidity (SM 2130-B) <br />- Total Suspended Solids (TSS) (SM 2540-D) <br />- Oil and Grease (EPA 1664) <br />2.. Drinking Quality Parameters (DQP) include: <br />- Sulfate -Iron <br />- Nitrate -Sodium <br />- Chloride -Fluoride <br />- Carbonate -Total Dissolved Solids (TDS) <br />- Bicarbonate - pH <br />- Calcium -TotalColiform <br />- Magnesium <br />3. Sfate of Colorado Mandatory Drinking Water Parameters (SDWA) specifically include: <br />- Arsenic -Fluoride <br />- Barium -Sodium <br />- Cadmium -Antimony <br />- Chromium -Beryllium <br />- Copper -Nickel <br />- Lead -Thallium <br />- Mercury -Cyanide <br />- Selenium -Sulfate <br />4. Sampling locations proposed are reflective of the anticipated progress of mining. "All" sampling locations <br />includes monitoring wells CRMW 1-7, 9, 16, and 39-42. <br />5. Each sampling event shall include any and all dewatering waters being discharged to recharge wells <br />tested at the source (mine sump or silt pond). <br />The DQP's are an indicator of how the users would view the water at the tap and the SDWA measurements <br />are for chronic or toxic levels with regard to human consumption and are standard sets analyzed by <br />Colorado Analytical Laboratories, Inc. (Appendix A). A sample set will also be collected from water being <br />delivered to recharge sites (if any) and tested for the same set of parameters proposed for the groundwater <br />monitoring wells. <br />4.1 Samale Collection <br />Field parameters will be recorded during the well purging process associated with each sampling event on a <br />standard Groundwater Sampling Record (refer to form in Appendix B) along with: <br />1) Site location and conditions; <br />2) Current and previous weather conditions; and <br />3) Field personnel. <br />Samples will be split into bottle containers which are provided by the laboratory with appropriate chemical <br />preservatives and stored on ice. Data collected during the field events will be analyzed after receipt of <br />laboratory testing results and a summary report will be issued based on the proposed schedule. <br />If a contaminant "spike" or marked increase is observed during field sampling or when laboratory results are <br />received, a letter report would be written to the DMG describing the issue and proposed action. If the <br />observed issue presented an immediate public health risk, this information would also be reported to the <br />CDPHE and local agencies. Potential mitigation measures are discussed in Section 4.3 below. <br />Groundwater Sampling and Analysis Plan October 2005 <br />Lupton Lakes Project -3- <br />
