The splits of <br /> the BLM samples were analyzed for polychlorinated biphanyls(PCBs)by Evergreen Analytical, Inc., <br /> an independent laboratory in Wheat Ridge, Colorado, using EPA Method $080. <br /> You will note that the analytical results for all Aroclors in all three of the samples were below the <br /> laboratory analytical detection limits or EPA's Contract Laboratory Program (CLP) Practical <br /> Quantitation Limit (PQL). These results are not consistent with those referenced by the EPA <br /> previously. In- my previous discussions with Mr. Fred Burnside, who is with. EPA's Criminal <br /> Investigations Bureau in Denver, he,indicated that he has not reviewed either BLM's analytical <br /> results or the associated QA/QC data, but only a one-page summary. At the direction of Mr. Fred <br /> Burnside with EPA, I have contacted Mr. Alan Kraus with BLM to obtain a copy of BLM's <br /> analytical results and QA/QC data for its spilt of the samples. I have been advised by Mr. Kraus <br /> as recently as this morning that he cannot release BLM's results to either Mid-Continue resources <br /> or to myself. <br /> If you have questions on the above or if I can provide any additional information, please feel free <br /> to call me. <br /> Sample Designations: <br /> #1A Sample collected by BLM from area of 'yellow staining' <br /> #1B Sample collected by BLM-from area of "red staining" <br /> #1 C Composite of samples collected by BLM from three areas with "dark'staining' <br />
