About this file
This document is a laboratory asbestos analysis report from Mountain Laboratories for bulk samples submitted by the U.S. Bureau of Reclamation (USBR) - California on February 7, 2025. The analysis was performed for the Shasta Maintenance Center External Sample Project (Project #1) at 16349 Shasta Dam Boulevard, Shasta Lake, CA 96019. The testing method employed was 40 CFR, Part 763, Subpart E, Appendix E using Polarized Light Microscopy (PLM) supplemented by Dispersion Staining (PLM/DS). Mountain Laboratories holds NVLAP accreditation (Lab Code 101890-0) and is located in Spokane Valley, WA.
The report documents analysis results for 69 bulk samples (plus three sub-samples) collected from the Shasta Maintenance Center. Of the samples analyzed, asbestos was detected in 11 samples: samples 6, 7, 10, 11, 30, 32, 33, 34, 41, and 42 contained chrysotile asbestos at 3-5% concentration in gray layers, while sample 6 also showed 3-5% chrysotile. The remaining 58 samples tested negative for asbestos (N.D. - Not Detected). All samples were treated through teasing, crushing, and/or heating processes. The report includes detailed composition data for each sample, noting the presence of non-fibrous materials such as quartz, paint, aggregate, and other mineral content. Chain of custody documentation is provided, with all samples received and analyzed on February 7, 2025 by Laboratory Manager Heidi L. Porret. Mountain Laboratories disclaims responsibility for sample procurement and notes that negative or minimal PLM results should be confirmed with SEM or TEM analysis for greater certainty.
