The Trump administration has announced a plan to eliminate drinking water limits on four PFAS ‘forever chemicals’ and delay implementation of standards for two other compounds. The proposal comes just two years after the US Environmental Protection Agency (EPA) set legally enforceable limits for six of the most dangerous PFAS compounds, which are linked to cancers and other serious health problems.
Details of the Proposed Rules
The EPA is proposing two separate rules to rescind and delay the limits. These rules must undergo an approval process that could take several years and are almost certain to face legal challenges. Public health advocates argue that reversing these limits would endanger the health of millions of Americans, as PFAS are estimated to contaminate drinking water for over 200 million people nationwide.
Statements from Officials
At a press conference on Monday, EPA Administrator Lee Zeldin and US Health Secretary Robert F. Kennedy Jr. announced the new plan. Zeldin stated, “The Trump EPA is committed to Make America Healthy Again by ensuring clean air, land, and water – and by taking on PFAS the right way, across the full life cycle and built to last.” Kennedy defended the move, claiming the administration is implementing a “clean water mandate” and that reports of rolling back protections are false.
Health and Environmental Concerns
PFAS, or per- and polyfluoroalkyl substances, are a class of at least 16,000 compounds used to make products water-, stain-, and grease-resistant. They are dubbed ‘forever chemicals’ because they do not naturally break down in the environment. Exposure has been linked to cancer, birth defects, decreased immunity, high cholesterol, kidney disease, and other serious health issues. In 2024, the Biden administration set limits of 4 parts per trillion (ppt) for PFOA and PFOS, and 10 ppt for combinations of other PFAS compounds, marking the first new drinking water standards in 27 years. The EPA estimated these limits would reduce exposure for 100 million people and prevent thousands of illnesses.
Criticism from Advocates
Public health advocates strongly condemned the proposed rollback. Dr. Anna Reade, director of PFAS advocacy at the Natural Resources Defense Council, said, “Zeldin and Kennedy are trying to sell potions out of the back of a covered wagon. The millions of Americans demanding safe drinking water are not going to fall for their hocus pocus.” The move is seen as contradictory to Donald Trump’s pledge to eliminate toxic chemicals from drinking water, and highlights tensions between the Make America Healthy Again (MAHA) movement and traditional MAGA priorities.
The Trump administration argues that the Biden EPA did not follow proper legal procedures and moved too quickly, and that the limits would not survive a court challenge. They plan to “redo” the process to determine appropriate limits for the four chemicals, which they claim will save time by avoiding litigation. However, critics warn that this approach delays critical protections and puts public health at risk.
