The EPA is proposing to undo its rules for four PFAS chemicals (PFHxS, PFNA, GenX, and a mix including PFBS) in drinking water because the original process wasn’t done right.

This helps water providers get ready without rushing, keeping our drinking water safe. The EPA wants your thoughts and will hold a public hearing in July 2026 to hear from everyone.
