PFAS OUT Cannot Replace Broad Drinking Water Protections
PFAS OUT is an EPA outreach program for public water systems. EPA contacts systems with elevated PFOA or PFOS and points them to treatment guidance and funding information. The enforceable limits come from EPA’s drinking water rule. EPA has said it plans to rescind and reconsider the parts of that rule covering PFHxS, PFNA, GenX and chemical mixtures. This analysis explains why outreach cannot stand in for enforceable limits. It also covers what a narrower rule means for water systems, regulated companies and communities in PFAS litigation.

Common questions
What is EPA's PFAS OUT program?
PFAS OUT, short for PFAS Outreach, is an EPA program launched on April 14, 2026. EPA identifies public water systems with elevated PFOA or PFOS and contacts them directly. It connects them with treatment guidance, funding information and technical-assistance resources. EPA says the program itself provides no direct funding or direct technical assistance.
Which PFAS drinking water limits is EPA reconsidering?
On May 14, 2025, EPA said it would keep the national drinking water standards for PFOA and PFOS. It also said it intends to rescind and reconsider the limits for PFHxS, PFNA and HFPO-DA, known as GenX, along with the hazard index for mixtures. That announcement was a plan to revisit those parts of the rule through further rulemaking.
Does rescinding a PFAS limit mean the chemical is safe?
No. A rescission changes the rule, and it makes no finding about safety. The effect in litigation is on evidence. A federal standard is a strong reference point in a contamination case. Without one, plaintiffs may have to work harder to show why PFHxS, PFNA, GenX or combined exposure is still a serious health and legal issue.
