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 means public water systems won’t have to monitor or treat these chemicals for now. People and water providers should weigh in by July 20, 2026, and a virtual hearing happens July 7.

The EPA is giving water systems more time to meet safety rules for two harmful chemicals, PFOA and PFOS, by extending the deadline from April 2029 to April 2031 if they ask for it. 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.

This means certain limited uses of TCE won’t have to follow new restrictions just yet, while courts review the rules.
