EPA Announces New Method 533 for PFAS in Drinking Water
On December 18th, EPA announced the new validated Method 533 for testing additional short chain per- and polyfluoroalkyl substances (PFAS) in drinking water. Method 533 measure PFAS by isotope dilution anion exchange solid phase extraction and liquid chromatography/tandem mass spectrometry (LC-MS/MS). The lowest concentration minimum reporting levels (LCMRLs) for the method analytes are provided in a table and range from 1.4 to 16 nanograms/L ((ng/L) or parts per trillion (ppt)). The combination of this new method and existing EPA methods can now measure 29 different PFAS compounds in drinking water.
