The Hawaii Department of Health (HDOH) in December updated its PFAS Environmental Action Levels (EALs). The updates include adding soil and groundwater action levels for 6:2 Fluorotelomer sulfonate (an action the agency noted as important given a recent release of AFFF at a Navy fuel facility in the state); revising action levels for HFPO and PFHxA to reflect U.S. EPA toxicity factors; and updating action levels for PFOS, PFOA, PFHxS, and PFNA to reflect ATSDR toxicity factors. The ATSDR toxicity factors have also been incorporated into EPA’s Regional Screenings Levels guidance.
The agency anticipates additional updates to the EALs in 2023 as new guidance on key compounds of interest, laboratory methods, toxicity studies, and related information are compiled and reviewed by HDOH staff. This includes review of EPA’s interim drinking water advisory levels for PFOA and PFOS, anticipated publication of EPA’s draft Maximum Contaminant Levels for the same compounds, and increased understanding of health impacts from exposure to individual PFAS.
