Minneapolis, MN, June 15, 2022 – Pace® Analytical Services, a division of Pace® Science and Technology Company and the preferred provider of in-lab, mobile, emergency onsite specialty contaminant, and regulatory testing and analysis services announced today they have received accreditation for EPA Draft Method 1633 for the US Department of Defense (DOD) Accreditation. The accreditation includes 40 PFAS compounds found in water, solids, and tissue.

The US DOD has required that all requests for PFAS analysis issued after January 1, 2022, be carried out using EPA Draft Method 1633. “As the leader in PFAS testing and one of the early adopters of the DOD quality control systems, we are pleased to be one of the first labs to be accredited by the DOD. We’re looking forward to supporting our federal and commercial clients’ testing requirements with this method at multiple Pace® facilities,” stated Mike McFadden, Federal Program Manager, at Pace®.

EPA Draft Method 1633 provides a standardized approach for measuring up to 40 PFAS in a diverse range of environmental matrices including: wastewater, surface water, groundwater, soil, biosolids, sediment, landfill leachate, and biological tissue. This draft method incorporates PFAS testing by isotope dilution, a technique used by Pace® that quantitates PFAS compounds. In addition to DOD facilities, EPA Draft Method 1633 will be used by many Pace® customers for commercial and industrial testing and reporting.
