The analysis of PFAS by EPA 1633A and ASTM D8421 is part of the U.S. EPA’s Methods Update Rule (MUR) Rule 22. The action will promulgate EPA into 40 CFR Part 136. Also part of this action, PFAS method ASTM D8421 is proposed to be codified.
To support PFAS investigations, monitoring, and scientific studies, Merit Laboratories has expanded its list of available PFAS compounds for environmental laboratory testing. Merit now provides analytical testing for 46 PFAS compounds by LC/MS/MS with isotopic dilution. Results were validated by the laboratory in an October 2020 Method Detection Limit (MDL) study.
Four new compounds have been added to the State of Michigan’s minimum laboratory PFAS analyte list, bringing the total to 28. The list is maintained by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) for the testing of drinking water, groundwater, surface water, wastewater, soil, and landfill leachate.
