Stop EPA’s Proposed New Rules to Allow Continued Poisoning of America’s Drinking Water with Toxic PFAS Chemicals
In a recent EPA <a href="https://www.epa.gov/newsreleases/epa-advances-comprehensive-pfas-strategy-legally-defensible-practical-scientifically" target="_blank">announcement</a>, EPA Admini strator Lee Zeldin, alongside HHS Secretary Robert F. Kennedy, Jr., proclaimed the agency was Making America Healthy Again by tackling the issue of <a href="https://toxinfreeusa.org/education/what-are-pfas-forever-chemicals-and-how-to-avoid-them/" target="_blank">toxic PFAS chemicals</a> in the nation’s drinking water.
In the bizarre statement, Zeldin said the solution to removing toxic PFAS chemicals in our drinking water was not to regulate and remove PFAS in drinking water, but to deregulate.
In 2024, the Biden EPA finalized the <a href="https://www.epa.gov/newsreleases/biden-harris-administration-finalizes-first-ever-national-drinking-water-standard" target="_blank">first-ever legally enforceable PFAS National Primary Drinking Water Regulation</a> to begin protecting Americans from PFAS pollution. The rule set limits for six individual PFAS: PFOA and PFOS limits were set at 4.0 parts per trillion (ppt) maximum contaminant level (MCL). The MCL for PFNA, PFHxS, and HFPO-DA (also known as GenX) was set at 10 ppt. The rule also set a limit for mixtures of any two or more of four PFAS: PFNA, PFHxS, PFBS, and GenX chemicals. Overall the rule would have regulated six of the most widely-used PFAS.
The rule would have given public water systems until April 26, 2027 to complete the first round of PFAS testing and reporting, and until April 26, 2029 to implement treatment and reduce PFAS to meet the standards.
This rule was proposed after years of reviewing extensive research and independent peer-reviewed science, and after a public comment period that amassed over 120,000 comments from the public, including GMO/Toxin Free USA, overwhelmingly in support of the rule.
But now, Trump’s EPA has proposed rescinding the Biden-era rule and is proposing two new rules instead.
In the first rule, the EPA is “proposing to rescind its regulatory determinations to regulate four PFAS PFHxS, PFNA, HFPO-DA, commonly known as GenX, and mixtures of these three PFAS plus PFBS under the Safe Drinking Water Act. The EPA is also proposing to rescind all associated regulatory provisions currently codified in the EPA's 2024 PFAS National Primary Drinking Water Regulations.”
In the second rule, the EPA “proposes a federal exemption that will extend the dates of compliance with the Maximum Contaminant Levels (MCLs) for PFOA and PFOS from April 26, 2029, to April 26, 2031.”
In plain English: what the EPA wants to do is to drop regulation on four of the six PFAS and delay the regulation of the remaining two. Keep in mind that there are potentially over 15,000 PFAS chemicals used in manufacturing. So regulating six PFAS was only a start.
Unfortunately, gaslighting by Lee Zeldin and an EPA <a href="https://toxinfreeusa.org/the-environmental-protection-agencys-revolving-door-the-foxes-are-now-guarding-all-the-hen-houses/" target="_blank">stacked with chemical industry lobbyists</a> have become the norm.&nbsp;
Activists across the country have advocated and fought for decades for action on removing PFAS from drinking water. We cannot allow this ultra-corrupt administration, beholden to the chemical industry, to roll back progress in protecting public health.
“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. By repealing and delaying PFAS standards, EPA is abandoning communities in desperate need of drinking water protections, especially those who live near polluting industries,” <a href="https://www.commondreams.org/news/trump-pfas" target="_blank">said Anna Reade</a>, director of PFAS advocacy at the Natural Resources Defense Council.
By law, the EPA must provide a public comment period on these changes. Because the EPA wants to make commenting difficult, they have created two separate dockets, one for each proposed rule. The suggested comment texts are editable and we encourage you to write them in your own voice.

ACTION 1 of 2: Stop the EPA Rescission of PFAS Drinking Water Regulation

I strongly oppose EPA’s proposal to rescind PFAS contamination standards in drinking water.

PFAS “forever chemicals” are linked to cancer, immune system harm, reproductive and developmental problems, and other serious health risks. New research shows PFAS are now present in 98.8% of human blood samples tested in the United States.

The EPA, an agency with a core mission to “protect human health and the environment,” should strengthen protections for public health — not roll them back. This new rule to rescind maximum contaminant levels for the four PFAS chemicals is a giveaway to the chemical industry and polluters and is unacceptable.

The agency must keep and enforce strong PFAS drinking water limits, hold polluters accountable, and prioritize clean, safe drinking water for everyone.

Do not rescind PFAS contamination standards in drinking water

I oppose EPA’s proposal to rescind protections against PFAS contamination in drinking water.

PFAS are toxic “forever chemicals” that persist in the environment and accumulate in the human body. Exposure has been linked to cancer, liver damage, immune system suppression, developmental harms, reproductive problems, and other serious health effects. Nearly every American is already carrying PFAS in their blood, and drinking water remains one of the most significant pathways of exposure.

Weakening drinking water standards would place the interests of the chemical industry and polluters above the health and safety of communities. Families should not have to worry that the water coming from their taps contains chemicals known to pose long-term health risks.

EPA’s responsibility is to protect public health and ensure access to safe drinking water. The agency should maintain and fully enforce strong PFAS drinking water standards for PFNA, PFHxS, PFBS, and GenX, accelerate cleanup efforts, and hold polluters accountable for the contamination they have caused.

NO rescission of PFAS contamination standards in drinking water

I urge EPA to reject its proposal to weaken PFAS drinking water regulations.

For decades, communities across the country have been exposed to PFAS contamination without their knowledge or consent. These chemicals are extraordinarily persistent, do not break down naturally, and have been associated with cancer, immune dysfunction, developmental impacts, reproductive harms, and other serious health concerns.

Rolling back existing protections would force affected communities to bear the burden of continued contamination while responsible corporations avoid accountability. Many of the hardest-hit communities are already facing economic and environmental challenges and cannot afford further delays in addressing this public health crisis.

The EPA’s mission is to protect human health and the environment. That mission requires stronger action on PFAS, not weaker standards. EPA should preserve current drinking water protections, enforce compliance, make polluters pay, and ensure that every community has access to clean, safe, PFAS-free drinking water.
