About this file
This is a Certificate of Analysis from Pace Analytical Services documenting asbestos testing results for bulk samples collected at Colorado Northwestern Community College. The testing was conducted for Mesa Environmental on behalf of Project ID 26005190, with samples collected on February 7, 2026, received on February 13, 2026, and analyzed on February 16, 2026. The laboratory tested eight sample groups containing multiple layers totaling fifteen individual samples using EPA-approved methods (EPA 600/R-93/116 and 40 CFR Appendix E to Subpart E of Part 763) for detecting asbestos in bulk building materials and insulation samples. The samples included various building materials such as drywall, joint compound, insulation, texture coatings, tape, and paper wrapping, with physical descriptions and composition percentages documented for each layer.
All tested samples returned non-detectable (ND) asbestos results, indicating no asbestos was identified in any of the bulk samples analyzed. The testing was approved by analyst Rasha Abdelmalak and signatory Miguel Ines Pace at the El Monte facility located at 3565 Lexington Ave., El Monte, California. The client contact was John Witkamp at Mesa Environmental, 3006 Vin Rose Way, Grand Junction, Colorado 81504. The report was issued on February 17, 2026, providing clearance documentation for the construction materials at the Colorado Northwestern Community College project.

General Notes
Notes Required by NVLAP
● Pace Analytical Services, LLC is not responsible for the sampling activity.
Pace Analytical Services - El Monte

● ND indicates no asbestos was detected; the method detection limit is 1 %.
● All regulated asbestos minerals (i.e. chrysotile, amosite, crocidolite, anthophyllite, tremolite, and actinolite) were sought in every layer of each sample, but only those asbestos minerals detected are listed.
● Tile, vinyl, foam, plastic, and fine powder samples may contain asbestos fibers of such small diameter (< 0.25 microns in diameter) that these fibers cannot be detected by PLM. For such samples, more sensitive analytical methods (e.g. TEM) are recommended if greater certainty about asbestos content is required. Semi-quantitative bulk TEM floor tile analysis is accepted under NESHAP regulations.
● These results are submitted pursuant to Pace® Building Sciences' current terms and conditions of sale, including the company’s standard warranty and limitation of liability provisions. No responsibility or liability is assumed for the manner in which the results are used or interpreted.
● This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST, or any agency of the Federal Government.
● This test report relates only to the items tested.
● This report is not valid unless it bears the name of a NVLAP-approved signatory.
● Any reproduction of this document must include the entire document in order for the report to be valid.
● Unless notified in writing to return the samples covered by this report, Pace® Building Sciences will store the samples for a minimum period of thirty (30) days before discarding. A shipping and handling charge will be assessed for the return of any samples.
● Pace® Building Sciences does not guarantee the results of tape lifts, microvacs, wipe, and/or debris samples. Accurate analysis cannot be performed due to particle size, media used, and/or amount of material given. Analysis of these materials should be performed by a TEM. A result of ND does not indicate that the sample area does not contain asbestos. It means the analyst could not identify asbestos in the specific sample for the reasons listed above.
● "When joint compound and/or tape is applied to a wallboard it becomes an integral part of the wallboard and in effect becomes one material forming a wall system," EPA 40 CFR Part 61. Pace® Building
Sciences cannot distinguish joint compound from the same material used as skim coat. Therefore, it is very important that individuals collecting the samples clearly describe the sample composition so Pace®
Building Sciences knows that the drywall system can be composited. If only joint sampling areas show layers with >1% asbestos, then material is joint compound. If samples from both joint sampling area and non-joint areas show layers with >1% asbestos, then the material should be considered "skim coat" or add-on material.
