However, the EPA plans to scrap MCLs for four other forever chemicals: PFNA, PFHxS, GenX, and PFBS.
"These four chemicals are the ones currently in use because industry developed them to replace PFOA and PFOS, so they are the chemicals most likely to increase contamination in the future," explained former senior EPA water official Betsy Southerland in a statement issued by the Environmental Protection Network on Wednesday.
"It is incredibly inefficient to regulate them years after the treatment has been installed only for PFOA and PFOS," Southerland added. "[EPA Administrator Lee] Zeldin's announcement on PFAS drinking water standards ensures that America's children will be drinking PFAS for another decade while he slows drinking water and wastewater PFAS treatment for years."
The EPA also pushed back the deadline for compliance with a Biden administration rule finalized last year aimed at ensuring polluters pay forever chemical cleanup costs, from 2029 to 2031. Earlier this week, the EPA said it is delaying a key PFAS reporting rule by one year.
"This is a betrayal of public health at the highest level," Environmental Working Group president Ken Cook said in response to Wednesday's announcement.
"You can't make America healthy while allowing toxic chemicals to flow freely from our taps.
The EPA is caving to chemical industry lobbyists and pressure by the water utilities, and in doing so, it's sentencing millions of Americans to drink contaminated water for years to come."
"The cost of PFAS pollution will fall on ordinary people, who will pay in the form of polluted water and more sickness, more suffering, and more deaths from PFAS-related diseases," Cook added.
"Zeldin's announcement on PFAS drinking water standards ensures that America's children will be drinking PFAS for another decade."
Approximately half of the U.S. population is drinking PFAS-contaminated water, "including as many as 105 million whose water violates the new standards," according to the Natural Resources Defense Council (NRDC), which added that "the EPA has known for decades that PFAS endangers human health, including kidney and testicular cancer, liver damage, and harm to the nervous and reproductive systems."
Forever chemicals—so called because some of them take up to 1,000 years to break down in the environment—have myriad uses, from nonstick cookware to waterproof clothing to firefighting foam. Increasing use of forever chemicals has resulted in the detection of PFAS in the blood of nearly every person in the United States and around the world.
"The PFAS contamination crisis is much larger than just two chemicals, and there is increasing evidence that other PFAS chemicals that pollute water harm health," Cook said. "Eliminating all PFAS chemicals from drinking water is an urgent public health priority."
"If this administration is serious about making America healthier, it needs to prove it by stopping PFAS from contaminating our drinking water," he added.
NRDC senior strategic director of health Erik Olson said Wednesday that "with a stroke of the pen, the EPA is making a mockery of the Trump administration's promise to deliver clean water for Americans."
"With this action, the EPA is making clear that it's willing to ignore Americans who just want to turn on their kitchen taps and have clean, safe water," Olson asserted. "The EPA's plan to retain but delay standards for two legacy forever chemicals may offer modest consolation to some, but throwing out protections against four others will be devastating."
"The law is very clear that the EPA can't repeal or weaken the drinking water standard. This action is not only harmful, it's illegal," Olson stressed. The Safe Drinking Water Act contains an "anti-backsliding" provision prohibiting the EPA from repealing or weakening the standard.
"With a stroke of the pen, the EPA is making a mockery of the Trump administration's promise to deliver clean water for Americans."
Kelly Moser, senior attorney and leader of the Water Program at the Southern Environmental Law Center—which successfully sued the industrial chemicals giant Chemours to stop PFAS contamination in North Carolina—said Wednesday that "when this administration talks about deregulation, this is what they mean—allowing toxic chemicals in drinking water at the request of polluters."
"This action also undercuts Administrator Zeldin's acknowledgment of the severe health harms of PFAS; what people need are protections from pollution, not press releases feigning concern," Moser added.
Food & Water Watch water program director Mary Grant said Wednesday that "today's decision is a shameful and dangerous capitulation to industry pressure that will allow continued contamination of our drinking water with toxic PFAS."
"Once again, the Trump administration has demonstrated that its priority is bending to corporate interests, not protecting the safety and well-being of everyday people," Grant continued. "Nothing is safe from Trump's greed-driven agenda—not even our drinking water."
"This will cost lives," she warned.
