Description
The Hawaii Department of Health Hazard Evaluation and Emergency Response (HEER) Office has updated its interim Soil and Water Environmental Action Levels (EALs) for per- and polyfluoroalkyl substances (PFAS). The February 2025 revision adds HFPO-DA (GenX) to the 'Primary Terminal PFASs' category due to its recalcitrance to breakdown in the environment and TOPs processing. The update includes new sample data input capability for HFPO-DA in the accompanying Total PFAS Risk calculator. Hawaii maintains one of the most comprehensive sets of risk-based PFAS action levels in the United States, covering 24 PFAS compounds.
