Home / PFAS Testing / DOD Test Methods
The DOD QSM (Quality Systems Manual) Is not a test method per se. Instead, it is a set of protocols to be used for DOD projects. QSM 5.3 and 5.4 are also applicable to civilian projects upon the client organization’s direction (e.g., In the absence of an applicable final US EPA test method), and Pace® adheres to them unless other SOPs are required for regulatory purposes.
QSM v5.3 Table B-15 lists the specific requirements for analyzing PFAS in matrices other than drinking water. QSM v5.4 was published in late 2021, adding Table B-24 to refine Draft Method 1633 for DOD projects. Both QSM v5.3 an v5.4 are currently valid, but it’s anticipated that these versions will be superseded by QSM v6.0 when it is finalized. (Expected in late 2022)
Military installations are heavy users of AFFF. Although newer foams are formulated without PFAS, they have yet to be cleared by the FAA or the DOD for use in an aviation emergency. AFFF also has a long shelf life and the chemical ingredients aren’t always clearly listed. To support compliance with MIL-SPEC, the DOD has developed this method for testing the PFAS content in these foams.
DOD has been collaborating with EPA on the development of Draft Method 1633 and SW-846 Draft Method 8328. These methods will be universally required for civil and DOD testing along with QSM 5.3 and 5.4 adding additional quality control requirements.
We’re certified/accredited by NELAC, ISO, DOD, DOE, and in every state with a PFAS lab certification program.
For emergencies, our Rapid Response Team can provide defensible results in as little as 24 hours.
We are committed to helping our customers advance their important work through building strong relationships, delivering upon expectations, and providing exceptional customer service.
We can test for PFAS in both solid and aqueous matrices, including potable and non-potable waters, soils, and biota.
We’re on the leading edge of science, working with EPA, DOD, ASTM, and others to develop new methods for analyzing PFAS.
