SJR utilizes independent third party certified laboratories to analyze all samples taken throughout the course of a project. They ensure priority is given to samples when submitted and work to provide quick turnaround times and immediate responses. This is especially important in emergency response situations and adds substantial value to SJR’s services. These laboratories are fully accredited under the National Voluntary Laboratory Accreditation Program (NVLAP) for airborne asbestos fiber analysis and bulk asbestos fiber analysis. They perform analysis by polarized light microscopy (PLM) with dispersion staining techniques per EPA methodology (40 CFR 763, Subpart F), as well as Transmission Electron Microscopy (TEM) analyses according to the Interim Transmission Electron Microscopy Analytical Methods contained within AHERA (40 CFR Part 763 Appendix A, Subpart E). These 3rd party certified laboratories are also proficient in lead-based paint analysis of bulk, wipe, air and water samples by Atomic Absorption Spectroscopy (AAS).
