About this file
This document is a Polarized Light Microscopy Bulk Asbestos Analysis Report prepared by Micro Analytical Services, Inc. for Cherokee Nation 35, LLC, focusing on samples collected from Building 122 at Fort Bliss, Texas. The laboratory analysis examined six different samples from the building, including black fibrous roof shingles and penetration materials, using EPA-approved testing methods. Notably, none of the tested samples were found to contain asbestos.
The report details the composition of the samples, which include roof shingles composed of 20% fibrous glass, 40% aggregate, and 40% asphalt, and penetration materials containing 10% cellulose and 90% other materials. The analysis was conducted on April 18, 2025, using Polarized Light Microscopy with Dispersion Staining, and the laboratory is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) and licensed by the Texas Department of State Health Services.

Samples have been analyzed by the EPA - 40 CFR Appendix E to Subpart E of Part 763, Interim Method of the Determination of Asbestos in Bulk Insulation Samples, EPA - 600/R-93/116: Method for the Determination of Asbestos in Bulk Building Material. The test results herein relate only to the sample submitted and analyzed. This report may only be reproduced in full with the approval of the Bulk Asbestos Laboratory of Micro Analytical Services (MAS). The above percentages are visual estimates of area percent. MAS is not responsible for any errors resulting from improper or incorrect sampling or shipping procedures. These samples will be retained for a period of 30 days. Accreditation by NVLAP in no way constitutes or implies product certification, approval, or endorsement by NIST. Some materials, especially floor tiles, contain asbestos fibers too thin to be detected by this method. NVLAP Lab Code: 200618 TDSHS License: 30-0341
