Wondering what PFAS are and how Trump's latest policy shift could affect your drinking water? Per- and polyfluoroalkyl substances, commonly called forever chemicals, have been a growing health concern due to their persistence in the environment and links to serious illnesses like cancer, liver damage, and reproductive issues. With the Environmental Protection Agency (EPA) now proposing to weaken key federal rules on PFAS in drinking water, questions are mounting about the health and safety of millions of Americans who rely on municipal water systems.
PFAS have been widely used since the 1940s in products such as nonstick cookware, water-repellent fabrics, and food packaging. They earned the nickname forever chemicals because they don’t easily break down in the environment or human body. Alarmingly, research shows these chemicals are now detectable in over 45% of U.S. tap water and in the bloodstream of the vast majority of Americans.
The health risks tied to PFAS exposure include cancer, weakened immune systems, hormonal disruption, and developmental issues in infants and children. Given these dangers, the EPA under the Biden administration had previously issued the first legally enforceable national limits on six of the most common PFAS compounds—PFOA, PFOS, PFNA, PFHxS, HFPO-DA (GenX), and PFBS.
The current administration is walking back those landmark protections. This week, the EPA—under direction from President Donald Trump—announced proposed rollbacks that would remove several of the regulated chemicals from the list, extend compliance deadlines from 2029 to 2031, and allow more exemptions for water systems. Most notably, GenX substances, initially introduced as safer alternatives to older PFAS, may be dropped from regulation despite mounting evidence of their risks.
This means fewer legally enforced limits on PFAS in your tap water, potentially leaving communities exposed to dangerous levels for years to come.
The rollback has triggered fierce criticism from environmental watchdogs and public health advocates. “Today’s decision is a shameful and dangerous capitulation to industry pressure,” said Mary Grant, water program director at Food & Water Watch. She warned the move will inevitably lead to more contaminated water systems and serious health consequences.
Advocacy groups are especially concerned that these changes favor chemical manufacturers and water utilities at the expense of public health. While industry groups applaud the “flexibility” and cost savings, critics argue that Americans shouldn't have to trade clean water for corporate convenience.
According to EPA Administrator Lee Zeldin, the agency’s updated timeline and relaxed regulations are meant to relieve small, rural water systems of the financial burden of immediate compliance. The National Rural Water Association echoed this view, citing high treatment costs and the need for affordable filtration technologies. However, delaying enforcement means communities could remain exposed to toxic chemicals for even longer.
With PFAS clean-up estimated to cost billions, and companies like 3M already settling lawsuits for hundreds of millions of dollars over contamination, many experts believe prevention through regulation is the more cost-effective and ethical solution.
Several states have already signaled they won’t wait for weakened federal guidelines. New Jersey, for instance, just secured a $450 million settlement with 3M over PFAS pollution and maintains its own stricter water safety rules. Legal challenges to the EPA’s proposed rollback are likely, especially from states that have invested heavily in clean water initiatives.
Environmental lawyers say the EPA may struggle to justify a reversal of science-backed policies without new evidence. Any move to water down standards could face intense scrutiny in court and from Congress.
If you’re concerned about the safety of your tap water, now is a critical time to stay informed. You can request a local water quality report from your utility provider and consider investing in a certified water filtration system designed to remove PFAS. Public support and pressure on local, state, and federal lawmakers are also essential in ensuring that health remains the top priority.
As PFAS contamination remains one of the most pressing environmental and public health issues in the U.S., weakening federal protections threatens to undo years of progress in clean water advocacy.
