The splits of <br />the BLM samples were analyzed for polychlorinated biphenyls (PCBs) by Evergreen Analytical, Inc., <br />an independent laboratory N Wheat Ridge, Colorado, using EPA Method 8080. <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 Conaact Laboratory Program (CLP) Practical <br />Quantitation Limit (PQL). These resulu 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 analydcal <br />results or the associated QA/QC data, but only cone-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 split 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-Continent 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 /> <br />" Sample Designations: <br />q1A Sample collected by BLM from azea of "yellow staining" <br />II1B Sample collected by BLM from azea of "red staining" <br />N1C Composite of samples collected by BLM from three azeas with "dark staining" <br />
