The Trump administration is facing mounting criticism from environmental organizations, public health advocates, and clean water campaigners after the Environmental Protection Agency announced plans to weaken and delay major federal drinking water protections targeting toxic “forever chemicals,” a move critics say threatens to expose millions of Americans to dangerous contaminants for years to come. The proposal marks one of the most significant environmental regulatory reversals of President Donald Trump’s second term and has intensified accusations that the administration is prioritizing chemical industry interests and corporate lobbying pressure over public health protections.
The EPA announced Monday that it intends to delay compliance deadlines for limits on two widely studied PFAS chemicals, PFOA and PFOS, while eliminating federal restrictions altogether for four additional compounds: PFBS, PFHxS, PFNA, and HFPO-DA, also known as GenX. The changes would roll back portions of the Biden administration’s landmark drinking water regulations, which environmental advocates had previously praised as the first major nationwide effort to limit exposure to PFAS contamination in public water systems.
Per- and polyfluoroalkyl substances, commonly referred to as PFAS, are known as “forever chemicals” because they persist in the environment and in living organisms for extremely long periods without naturally breaking down. The chemicals have been widely used for decades in industrial manufacturing and consumer products including firefighting foam, food packaging, nonstick cookware, and water-resistant fabrics used in clothing and furniture. Scientific concern surrounding PFAS contamination has grown steadily as researchers and public health experts linked exposure to serious health conditions including cancer, liver damage, developmental problems, and elevated risks for children and pregnant women.
The Biden administration’s original PFAS drinking water standards were widely described as historic because they established enforceable federal limits designed to reduce exposure to some of the most dangerous and widespread PFAS contaminants. Environmental groups had pushed the administration to regulate an even broader range of PFAS chemicals, arguing that contamination had already spread through water systems across the country and that many communities had waited years for meaningful federal intervention.
The Trump administration is now arguing that the Biden-era standards failed to properly comply with federal law and that the new proposals align with Trump’s “Make America Healthy Again” agenda. EPA Administrator Lee Zeldin and Health and Human Services Secretary Robert F. Kennedy Jr. defended the rollback Monday by promoting “innovative” technologies and additional funding support for states addressing PFAS contamination in drinking water systems.
The proposed rules are expected to be published in the Federal Register and will enter a 60-day public comment period before any final action is taken. The EPA has also scheduled a public hearing for July 7. Environmental organizations, however, immediately condemned the proposals and warned that delaying or eliminating PFAS protections would extend toxic exposure for communities already dealing with contaminated drinking water.
Anna Reade, director of PFAS advocacy at the Natural Resources Defense Council, accused administration officials of attempting to disguise deregulation as a public health initiative while abandoning communities that have long demanded stronger protections from industrial contamination.
“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,” Reade said in a statement.
“By repealing and delaying PFAS standards, EPA is abandoning communities in desperate need of drinking water protections, especially those who live near polluting industries,” she added.
Critics of the rollback argue that the consequences of prolonged PFAS exposure are not theoretical because contamination has already been identified in communities throughout the United States, particularly near industrial facilities, military installations, airports, and manufacturing centers where PFAS-containing products were heavily used for decades. Environmental advocates say federal standards were considered essential because local governments and residents often lacked the financial resources and legal authority necessary to force large-scale cleanup efforts on their own.
Food and Water Watch water program director Mary Grant warned that the Trump administration’s proposal would leave millions vulnerable to ongoing contamination while weakening hard-fought public health protections secured only after years of organizing and scientific research.
“With today’s proposals, the Trump administration is telling the public to drink poison,” Grant said. “It has once again shown that it represents the interests of billionaire corporate polluters—not the health of people in this country.”
Grant also argued that communities affected by PFAS contamination have spent decades demanding stronger protections against chemicals that continue to circulate through public drinking water systems.
“One thing is absolutely clear, we cannot roll back or delay protections against PFAS,” she said. “For decades, communities have been sounding the alarm and demanding action on these toxic forever chemicals. Instead of implementing commonsense regulations, Trump’s EPA has doubled down on weakening our drinking water protections. Every person deserves and needs clean, safe water, and today’s proposed rules are threats to millions of people.”
Grant called on the EPA to halt its deregulatory effort entirely and pursue broader restrictions targeting PFAS chemicals as a class rather than limiting oversight to only selected compounds.
“EPA must not delay or roll back these hard-won limits on toxic PFAS contaminants in drinking water,” Grant said. “It must immediately cease these deregulatory actions, stop approving new PFAS chemicals, ban all nonessential uses, hold polluters accountable for clean up, expand protections to regulate the entire class, and ramp up support to ensure that every community has access to safe, affordable water.”
The Environmental Working Group, which has tracked PFAS contamination across the United States and publicly released extensive findings documenting affected communities, also condemned the administration’s proposal and accused federal regulators of siding with chemical industry lobbyists and water utility pressure campaigns rather than protecting public health.
“You cannot make America healthy again while allowing toxic PFAS to flow freely from our taps,” said Ken Cook, president and co-founder of the Environmental Working Group.
“The Trump EPA is caving to chemical industry lobbyists and water utility pressure—and in doing so, it is condemning millions of Americans to drink contaminated water for years to come,” Cook added.
Cook warned that the long-term consequences of weakening federal standards would ultimately be borne by ordinary residents exposed to contaminated drinking water over extended periods.
“The price of this decision will be paid by ordinary people, in the form of more PFAS-related diseases,” he said.
The legal battle over the proposed rollback may become a central issue as environmental organizations prepare challenges based on the Safe Drinking Water Act. While Trump administration officials argue that the Biden EPA improperly implemented the original regulations, environmental groups contend that weakening or repealing the standards may itself violate federal law. The Environmental Working Group pointed to provisions in the Safe Drinking Water Act requiring that any revision to drinking water standards must “maintain, or provide for greater, protection of the health of persons.”
Melanie Benesh, vice president of government affairs at the Environmental Working Group, said the administration’s proposal represented a conscious decision to weaken protections despite known health risks linked to PFAS exposure.
“This is a deliberate decision to expose American families to chemicals linked to cancer and other serious health harms,” Benesh said.
“Rolling back limits on four PFAS and then allowing water systems to push compliance deadlines to 2031, when contamination is ongoing, is unconscionable,” she added.
Benesh also warned that the communities least able to protect themselves financially or politically would likely experience the greatest consequences from delayed enforcement and weakened standards.
“The communities least able to protect themselves will pay the highest price,” she said. “That is not regulatory reform. It is an environmental injustice.”
Another environmental advocate quoted in the source material criticized the administration’s broader approach to public health protections and argued that weakening PFAS standards directly contradicts scientific evidence regarding the dangers associated with exposure.
“There’s nothing gold-standard about tearing down the science-based protections that help keep our drinking water safe,” the statement said. “PFAS are highly toxic, even at very low levels, and are linked to liver damage, cancers and other health problems for children and pregnant women. Needlessly exposing millions of Americans to PFAS prioritizes the interests of polluters over the rest of us. It’s another way the Trump administration is making life more dangerous for American families.”
Environmental advocates say the administration’s proposal now sets the stage for a major national fight over water safety, chemical regulation, and the future of environmental enforcement as public health groups, affected communities, and environmental organizations prepare to challenge the rollback during the public comment process and likely in court.
