National Drinking Water Standard Issued to Protect 100M People from PFAS

April 10, 2024
Legally enforceable standard to protect communities from harmful per-and polyfluoroalkyl substances (PFAS), also known as ‘forever chemicals.’

WASHINGTON, DC — On April 10 the Biden-Harris Administration issued the first-ever national, legally enforceable drinking water standard to protect communities from exposure to harmful per-and polyfluoroalkyl substances (PFAS), also known as "forever chemicals." 

Exposure to PFAS has been linked to deadly cancers, impacts to the liver and heart, and immune and developmental damage to infants and children. This final rule represents the most significant step to protect public health under EPA’s PFAS Strategic Roadmap. The final rule will reduce PFAS exposure for approximately 100 million people, prevent thousands of deaths, and reduce tens of thousands of serious illnesses. Today’s announcement complements the Biden administration’s government-wide action plan to combat PFAS pollution.  

EPA is also making unprecedented funding available to help ensure that all people have clean and safe water. In addition to today’s final rule, EPA is announcing nearly $1 billion in newly available funding through the Bipartisan Infrastructure Law to help states and territories implement PFAS testing and treatment at public water systems and to help owners of private wells address PFAS contamination. This is part of a $9 billion investment through the Bipartisan Infrastructure Law to help communities with drinking water impacted by PFAS and other emerging contaminants—the largest-ever investment in tackling PFAS pollution. An additional $12 billion is available through the Bipartisan Infrastructure Law for general drinking water improvements, including addressing emerging contaminants like PFAS.

The announcement of the final standard was made by EPA Administrator Michael Regan who joined White House Council on Environmental Quality Chair Brenda Mallory at an event in Fayetteville, North Carolina. In 2017, area residents learned that the Cape Fear River, the drinking water source for 1 million people in the region, had been heavily contaminated with PFAS pollution from a nearby manufacturing facility. Today’s announcements will help protect communities like Fayetteville from further devastating impacts of PFAS.

“Drinking water contaminated with PFAS has plagued communities across this country for too long,” said EPA Administrator Michael S. Regan. “That is why President Biden has made tackling PFAS a top priority, investing historic resources to address these harmful chemicals and protect communities nationwide. Our PFAS Strategic Roadmap marshals the full breadth of EPA’s authority and resources to protect people from these harmful forever chemicals. Today, I am proud to finalize this critical piece of our Roadmap, and in doing so, save thousands of lives and help ensure our children grow up healthier.”  

Enforcement

EPA is taking a signature step to protect public health by establishing legally enforceable levels for several PFAS known to occur individually and as mixtures in drinking water. This rule sets limits for five individual PFAS: PFOA, PFOS, PFNA, PFHxS, and HFPO-DA (also known as “GenX Chemicals”). The rule also sets a limit for mixtures of any two or more of four PFAS: PFNA, PFHxS, PFBS, and “GenX chemicals.” 

EPA estimates that between about 6% and 10% of the 66,000 public drinking water systems subject to this rule may have to take action to reduce PFAS to meet these new standards. All public water systems have three years to complete their initial monitoring for these chemicals. They must inform the public of the level of PFAS measured in their drinking water. Where PFAS is found at levels that exceed these standards, systems must implement solutions to reduce PFAS in their drinking water within five years.

Implementation

The new limits in this rule are achievable using a range of available technologies and approaches including granular activated carbon, reverse osmosis, and ion exchange systems. For example, the Cape Fear Public Utility Authority, serving Wilmington, NC—one of the communities most heavily impacted by PFAS contamination—has effectively deployed a granular activated carbon system to remove PFAS regulated by this rule. Drinking water systems will have flexibility to determine the best solution for their community.

EPA will be working closely with state co-regulators in supporting water systems and local officials to implement this rule. In the coming weeks, EPA will host a series of webinars to provide information to the public, communities, and water utilities about the final PFAS drinking water regulation.

To learn more about the webinars, please visit EPA’s PFAS drinking water regulation webpage. EPA has also published a toolkit of communications resources to help drinking water systems and community leaders educate the public about PFAS, where they come from, their health risks, how to reduce exposure, and about this rule.

Additionally, EPA has a nationwide Water Technical Assistance program to help small, rural, and disadvantaged communities access federal resources by working directly with water systems to identify challenges like PFAS; develop plans; build technical, managerial, and financial capacity; and apply for water infrastructure funding.

Reactions

“We learned about GenX and other PFAS in our tap water six years ago. I raised my children on this water and watched loved ones suffer from rare or recurrent cancers. No one should ever worry if their tap water will make them sick or give them cancer. I’m grateful the Biden EPA heard our pleas and kept its promise to the American people. We will keep fighting until all exposures to PFAS end and the chemical companies responsible for business-related human rights abuses are held fully accountable,” said Emily Donovan, co-founder of Clean Cape Fear, a community action group working to restore and protect our air, soil, water and food supply from PFAS contamination.
United Association of Union Plumbers and Pipefitters (UA) General President Mark McManus hailed the final rule as an important step forward. 

“For generations, the plumber has protected the health of the nation and worked to deliver clean and safe water to our communities. This legally enforceable drinking water standard will ensure that we continue our essential work and remove deadly PFAS contaminants from our water supply,” said McManus. “The Biden Administration is committed to protecting public health and making sure all infants and children can grow up without the deadly scourge of these forever chemicals. At the United Association, our members are incredibly proud of the work we do each and every day to achieve that goal. We look forward to our continued partnership with the EPA and the Biden Administration to deliver a future where clean and safe water, free from PFAS and other contaminants, is the norm.”
