Key Laboratories: Analyses of 20-3 Special Sample and Production Liquor. Some of these <br /> analyses exceed drinking water standards for fluoride, sulfide, total dissolved solids, chromium, <br /> copper, nickel and zinc. The sulfide report indicates that particulates are present. Analyses <br /> should be of dissolved metals, not totals. <br /> Evergreen Analytical: Production Liquor 6/19 and 6/18. Both samples show exceedances of <br /> benzene. <br /> Given that the analyses appear to represent whole water analyses rather than dissolved <br /> constituents, it is not possible to make a realistic appraisal of the metals and other parameters. <br /> Likewise, if whole water analyses were used for organic analyses, then the presence of benzene <br /> in all of the samples and toluene in two analyses makes the analyses impossible to evaluate as <br /> organics may be present in the solid fraction rather than the liquid or, presumably, the <br /> bioavailable fraction. <br /> The current response is not adequate. If the Operator feels the samples are adequately <br /> representative of the process solutions, then clearly the process solutions should be protected <br /> from all potential receptors—human, aquatic, and agricultural/livestock—and from cross- <br /> contaminating USDW resources. However, the Division needs more definitive analytical <br /> information on the process solutions for use if an emergency response need arises. <br /> cc: Carl Mount <br /> Jim Pendleton <br /> 2 <br />
