    On August 3, 2020, the State of Michigan adopted new regulations limiting seven PFAS chemicals in municipal drinking water. The new drinking water standards also update Michigan's existing groundwater clean-up criteria of 70 ppt for PFOS and PFOA. The new groundwater standard is 8 ppt for PFOA and 16 ppt for PFOS.

    On December 21, 2020, the following 5 additional PFAS compounds became groundwater cleanup criteria: PFNA (6 ppt), PFHxS (51 ppt), PFHxA (400,000 ppt), PFBS (420 ppt), and HFPO-DA (370 ppt).  EGLE staff use all 7 PFAS criteria to guide groundwater investigations, protect public health, and identify MPART PFAS sites.
