1On March 14, 2023, EPA announced a proposed NPDWR for six PFAS (GenX chemicals, PFBS, PFOS, PFOA, PFHxS, and PFNA). After EPA has considered public comments and publishes a final PFAS NPDWR, EPA will update the reference concentrations for these six PFAS as appropriate
2ppt: Parts per Trillion, equivalent to two drops of water in an Olympic-sized swimming pool
3 Hazard Index: A unitless value that represents additive health risk from chemical mixtures
