The EPA is finalizing National Primary
Drinking Water Regulations for six per- and polyfluoroalkyl
substances (PFAS) including perfluorooctanoic acid (PFOA),
perfluorooctane sulfonic acid (PFOS), perfluorohexane sulfonic acid
(PFHxS), perfluorononanoic acid (PFNA), hexafluoropropylene oxide
dimer acid (HFPO-DA, commonly known as GenX Chemicals), and
perfluorobutane sulfonic acid (PFBS). The EPA is finalizing Maximum
Contaminant Level Goals (MCLGs) for PFOA and PFOS at zero and the
enforceable Maximum Contaminant Level (MCL) at 0.0000040 mg/L or
4.0 ppt for each of these contaminants. The EPA is also finalizing
individual MCLGs and is promulgating individual MCLs for PFHxS,
PFNA and HFPO-DA at 10 ppt. Lastly, the EPA is finalizing a Hazard
Index (HI) of 1 (unitless) as the MCLG and MCL for any mixture
containing two or more of PFHxS, PFNA, HFPO-DA and PFBS.
