Wakhcr <br />Ezeculive Director <br />Michael B. long <br />Division Director <br />The Division received your notice to change labs for urocessing water samplrxs from the required <br />' ~" monitoring stations. You intend to ship all your water samples to the SVL Agalytical, Inc, lab in <br />^°I Kellogg, Idaho. <br />~• Pursuant to T.R.-06, the lab must be certified by the E.'A (Colorado Department of Public Health <br />I and Environment) and must comply with sample procc ssing protocol. You provided a copy of an <br />acceptable certification (which expires August 31, 2001) and a list of reporting limits and <br />processing methods which aze acceptable. The detectic n limits for three analytes seem to be too <br />high. I believe the detection limit should be at or less ti an 0.001 mgll for silver, cadmium and <br />lead. The reporting limits on page one (0.001 mg/1 for ~~Il but cadmium, which is 0.0001 m~,9) <br />would be acceptable detection limits. Submit an updated cert.ncate to the Division by October 1, <br />2001 and address the proposed detection limits for silvc r, cadmium and lead. <br />Remember, the samples must be shipped and received i) a chilled state (4 degrees Fahrenheit). <br />Failure to do so could compromise the analyses. In addil ion, all holding time linoitations must be <br />abided by in order to ensure accurate test results. <br />If you have any questions, please give me a call. <br />Sincerely, <br />lames Dillie <br />Environmental Protection Specialist <br />
