5/19/2026, 4:30:44 AM
Proposed Rollback of PFAS Drinking-Water Limits
On May 18, 2026 EPA Administrator Lee Zeldin announced that the agency will rescind the 2024 drinking-water limits for four PFAS—GenX (HFPO-DA), PFNA, PFHxS, and PFBS—while keeping enforceable limits for PFOA and PFOS. Utilities may apply for a two-year extension, pushing the compliance deadline from 2029 to 2031.
Legal and Policy Background
The 2024 rule, the first PFAS standard under the Safe Drinking Water Act, set 4 ppt limits for PFOA and PFOS and 10 ppt for PFNA, PFHxS, and GenX. EPA says the rule missed a public-comment period, breaching the act’s anti-backsliding provision.
Key Actors
Lee Zeldin, EPA Administrator – announced the rollback and $1 billion in grant funding.
Robert F. Kennedy Jr., HHS Secretary – co-presented the proposal and framed it as part of the “Make America Healthy Again” (MAHA) agenda.
Industry challengers include the American Chemistry Council and the National Association of Manufacturers; environmental opponents feature the Environmental Working Group, Natural Resources Defense Council, and Environmental Defense Fund.
Timeline of Recent Actions
2024 – Biden finalizes PFAS limits.
2025 – The American Chemistry Council and the National Association of Manufacturers, joined by water-utility groups, file lawsuits.
May 18 2026 – Trump EPA announces rescission and extension proposal.
July 7 2026 – Public hearing and 60-day comment period.
Extent of PFAS Contamination
EPA estimates PFAS appear in the drinking water of over 100 million Americans; other analyses suggest more than 200 million. Health effects include kidney and testicular cancer, immune suppression, developmental delays, high cholesterol, obesity, and reduced fertility.
Projected Health Impact
Eliminating limits for GenX, PFNA, PFHxS, and PFBS could raise exposure for millions, potentially reversing the 2024 rule’s projected cuts in kidney-cancer, bladder-cancer, low-birth-weight, and cardiovascular deaths. The two-year extension may delay mitigation in heavily contaminated areas.
Official Statements
Zeldin framed the change as “following the law and the science,” emphasizing that the new standards are “legally durable” and “gold-standard.” Kennedy described the action as a “clean water mandate” that corrects procedural shortcuts in the prior rule. EPA’s press release highlighted the $1 billion grant effort to help states address PFAS and other emerging contaminants.
Criticism & Opposition
Ken Cook warned the rollback “condemns millions of Americans to drink contaminated water for years.” Anna Reade called the move “incredibly concerning,” accusing Zeldin and Kennedy of “selling potions out of the back of a covered wagon.” EDF’s Maria Doa said the proposal is “contrary to MAHA.” Lawsuits allege a breach of the Safe Drinking Water Act’s anti-backsliding clause.
Conflicting Reports & Gaps
Sources differ on exposure estimates—EPA cites >100 million, while other analyses cite >200 million. EPA has not disclosed criteria for evaluating extension requests, leaving uncertainty about which utilities will qualify.

What’s Next
EPA will publish separate proposed rules for the four rescinded PFAS, open a 60-day comment period, and hold the July 7 hearing. Industry and environmental groups have signaled intent to pursue further litigation. Distribution of the $1 billion grant pool is slated to begin later in 2026, while the administration’s broader budget proposals may affect future funding for PFAS remediation.
