The Environmental Protection Agency (EPA) has significantly ramped up its focus on water safety in April 2026. While the primary initiative targets “forever chemicals” (PFAS), the agency has simultaneously expanded its scope to include other emerging contaminants.
Here are five major recent updates regarding this initiative:
Launch of the “PFAS OUT” Initiative
On April 14, 2026, the EPA launched the PFAS OUTreach (PFAS OUT) program. This initiative specifically targets roughly 3,000 water systems nationwide that are known to have significant challenges with PFOA and PFOS. The goal is to provide technical assistance and funding to help these communities reduce exposure years ahead of the federal compliance deadlines.
Microplastics and Pharmaceuticals Added to Priority List
In a landmark move on April 2, 2026, EPA Administrator Lee Zeldin added microplastics and pharmaceuticals to the draft Sixth Contaminant Candidate List (CCL 6). This is the first time in history that microplastics—found in human blood and organs—have been elevated to a priority group, unlocking federal research and paving the way for future enforceable limits in drinking water.
Compliance Deadline Extension for PFOA/PFOS
As part of the April 2026 rollout, the EPA finalized a rule to extend the compliance deadline for the two most common “forever chemicals,” PFOA and PFOS. While the Biden-era standards of 4 parts per trillion remain in place, the deadline for water utilities to meet these limits has been moved from 2029 to 2031. This change is intended to give smaller, rural water systems more time to secure funding and install filtration technology.
Rescinding of Limits for “GenX” and Other PFAS
The EPA has confirmed plans to rescind specific drinking water regulations for four less-common PFAS chemicals, including GenX (HFPO-DA), PFHxS, PFNA, and a “Hazard Index” for chemical mixtures. The agency stated it will reconsider these regulatory determinations to ensure they follow a more “flexible” legal process, though environmental groups like the NRDC have vowed to fight this rollback in court.
New PFAS Reporting Deadlines for Manufacturers
Effective April 13, 2026, the EPA finalized a rule under the Toxic Substances Control Act (TSCA) regarding PFAS recordkeeping. This mandate requires companies that manufactured or imported PFAS at any time since 2011 to report detailed data to the EPA. This massive data-collection effort is designed to help the agency map the “cradle-to-grave” lifecycle of these chemicals to better protect water sources from industrial runoff.
