The samples were received May 17, 1991, and initial results were <br />,:faxed to you on May 21, 1991. The objective of this a.Mlysis was to determine the presence <br />,hf asbestos using polarized light microscopy (pLM) and to visually estimate the percent by <br />I:. volume of asbestos and non-asbestos fibrous components. This report presents the results of <br />;:~ur analysis. <br /> <br />;PLM analysis has resulted in the detection of asbestos in 10 of the 24 samples submitted. <br />" <br />~Ana1ytical results and sample data are summarized in Table I. Each sample was examined for <br />'homogeneity. If a sample contains layered components, each layer is analyzed separately. <br />,< e results from the layers are then combined in proportion to their abundances for a single <br />fnalYSis of the sample. <br /> <br />8uIk asbestos analysis was conducted in accordance with the Environmental Protection <br />f gency's (BPA) method 40 CFR, Part 763, Ch. 1, (7-1-87 edition), subpart F, appendix A. <br />:~ality control information is available upon request. <br />~: <br />~ <br /> <br />rks <br /> <br />Intertec Environmental, Inc. is accredited by the National Institute of Standards and <br />,echnology (NIST), National Voluntary Laboratory Accreditation Program (NVLAP) #1234 <br />. r selected test methods. for bulk asbestos identification.
