In times where so many seek to divide us, politicians on both sides of the aisle have come together to sponsor a much needed bill to regulate toxic PFAS Forever Chemicals in our drinking water. And they need our support to get it over the finish line.
Congressman Brian Fitzpatrick (R-PA) and Congresswoman Debbie Dingell (D-MI), Co-Chairs of the bipartisan Congressional PFAS Task Force, introduced H.R.4168, the PFAS National Drinking Water Standard Act of 2025—bipartisan legislation to codify the Environmental Protection Agency’s (EPA) first ever national primary drinking water regulation for certain PFAS chemicals.
The legislation codifies the EPA’s final PFAS National Primary Drinking Water Regulation—issued on April 26, 2024—establishing enforceable maximum contaminant levels (MCLs) for six of the most hazardous PFAS chemicals, including PFOA and PFOS, in public drinking water systems. Unfortunately, the EPA rescinded parts and delayed other parts of the regulation this year.
By giving this rule the full force of federal law, the bill ensures these standards remain durable, enforceable, and insulated from future regulatory uncertainty or reversal.
It’s time to show our support for a strong PFAS regulation bill that has good, old fashioned bipartisan support. Sign the petition to tell your U.S. Representatives to pass H.R.4168, the PFAS National Drinking Water Standard Act of 2025.
Background
PFAS (per- and polyfluoroalkyl substances) are a class of very toxic carcinogenic and endocrine disrupting chemicals known as Forever Chemicals because they don’t break down in the environment.
In April, 2024, the Biden EPA established the first-ever national, legally enforceable drinking water standards for six PFAS. The rule set maximum contaminant levels (MCLs) for the six specific PFAS chemicals linked to cancers, liver and heart disease, and immune and developmental damage, to protect public health. This action was part of a broader bipartisan strategy to address PFAS pollution and was allocated significant funding in the Bipartisan Infrastructure Law.
Under the second Trump administration, however, the EPA, having been stacked with chemical industry lobbyists in all major positions of management, announced in May 2025 that it would roll back several regulations on PFAS in drinking water.
- The EPA rescinded the Maximum Contaminant Levels (MCLs) for four PFAS compounds: perfluorohexane sulfonic acid (PFHxS), perfluorononanoic Acid (PFNA), hexafluoropropylene oxide dimer acid (HFPO-DA, also known as GenX), and perfluorobutane sulfonic acid (PFBS).
- The EPA will keep the regulations for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) but is delaying the compliance deadline for water systems. The original deadline of 2029 was pushed back two years to 2031.
- The requirement for water systems to use a “hazard index” to address the cumulative risk of certain PFAS mixtures was also eliminated.
The Trump EPA has announced plans to propose a new, less stringent rule and establish an exemption framework for certain water systems.
The rollback of hard-fought, bipartisan PFAS regulations for drinking water, a giveaway to the chemical industry, is unacceptable. Several environmental groups have filed lawsuits to defend the original 2024 standards. But the outcome is uncertain and we shouldn’t sit idly by while these lawsuits play out in the courts. We need to demand action from our elected officials to protect public health today.
Tell your U.S. Representatives to Pass H.R.4168, the PFAS National Drinking Water Standard Act now.
