BULK SAMPLE ANALYSIS REPORT ^ CLIENT: City of Everett PRE#: 11331 3200 Cedar Street Report#: 897092 _ Everett, WA 98201 Report Date: 08/20/97 Project: 3510 Colby Ave Date Received: 08/12/97 ^ Date Analyzed: 08/13/97-OB/20/97 Page : 1 of 7 Analyst: Fred Golloway Attached are the results of analysis of33 bulk samples submitted for asbestos identification, lab ID #897092 through #897121 and #897259 through#897261. Samples were analyzed in accordance with method EPA-600/M4-82-020: "Interim Method for the Determination of Asbestos in Bulk Samples". Each sample was initially examined under a Nikon SMZ - 2T stereoscopic microscope at a magnification of 10X to 50X. Fibrous material was examined for morphology and content. Representative fibers from each sample were immersed in a fluid with a knowr. refractive index. The specimens were examined under polarized light using a Nikon Labophot microscope with a McCrone Dispersion Staining objective under 100X magnification. Optical characteristics of the fibrous material were examined to determine the mineralogy of the , fiber. The observed optical characteristics include angles of extinction, sign of elongatiun and refractive indices. Separate layers of inhomogeneous samples were analyzed and reported separately. Unless otherwise stated, asbestos content was quantified by calibrated visual estimation (CVES). �� Samples in which asbestos was not observed were reported "none detected". Test results pertain only to the samples submitted for analysis. This report can not be represented by the client to claim product endorsement by NVLAP or any agency of the U.S. Government.
