<br /> <br />DOCUMENT TITLE: Groundwater and Surface Water Monitoring Plan <br />1. Page 10, Water Quality Parameters List 1, and List 2. <br />a. For baseline groundwater samples, the DMG does not find it necessary to analyze the <br />following parameters. <br />phenol alkalinity <br />chemical oxygen demand <br />total suspended solids <br />cyanide <br />total nitrogen <br />ammonia <br />b. For baseline surface water samples, [he DMG does not find i[ necessary to analyze the <br />following parameters: <br />phenol alkalinity <br />cyanide <br />total nitrogen <br />ammonia <br />c. For baseline surface and groundwater samples, the following analyzes should be added to <br />the lists and the following corrections should be made: <br />pH (tenths of units, not units) <br />antimony <br />bicarbonate alkalinity <br />carbonate alkalinity <br />cobalt <br />total nitrate + nitrite <br />sulfide (as HAS) <br />thallium <br />uranium <br />gross alpha <br />gross beta <br />d. Analytical methods should be selected to detect the regulated parameters at the most <br />conservative regulatory levels. For instance, the aquatic standard for silver is lower than <br />the drinking water standard, so samples should be analyzed to detect silver at levels that <br />would affect aquatic life. Because of the high salinity of some waters, we would fully <br />anticipate that some parameters will not be detectable using the most rigorous methods. <br />In those cases, the operator should have the analytical labs verify the detectable limits for <br />future use. Detection limits were discussed recently with American Soda representatives. <br />We anticipate that a revised analyze and detection level list will be submitted very soon <br />and the DMG will review that list immediately. <br />
