Companies to pay billions in "forever chemical" water pollution settlements

• They also follow the Environmental Protection Agency tightening regulations on per- and polyfluoroalkyl substances (PFAS), which are a family of more than 12,000 chemicals.
• The chemicals have contaminated thousands of drinking water systems around the country, and most people living in the U.S. have some amount of PFAS in their blood, according to the Centers for Disease Control and Prevention.
• The health effects of the chemicals are still being studied, but exposure to certain levels of PFAS has been linked to adverse health effects in humans and animals, including increased risk of kidney or testicular cancer.

Driving the news: Chemours, DuPont and Corteva said Friday they reached a $1.19 billion settlement with water providers around the country.

• The water providers had alleged that the companies were responsible for environmental pollution from firefighting foams they manufactured that contained PFAS.
• Though the companies denied the allegations, the settlement would resolve hundreds of lawsuits against them that were consolidated in the federal district court for South Carolina, which must finalize the settlement for it to take effect.

What they're saying: John O'Connell, the board president of the National Rural Water Association, said in a statement that the settlement "is the beginning of helping our utility members in the fight against PFAS."

• The group works with 50 state associations representing more than 31,000 water and wastewater utility systems, and helped filed a lawsuit on behalf of its members.

Yes, but: Not included in the settlements are systems operated by states and the U.S. government, some smaller drinking water systems, and systems in the lower Cape Fear River Basin of North Carolina, which has been plagued by high levels of PFAS.

• Chemours, which produces products containing PFAS nearby, faces several lawsuits over PFAS exposure in the area.

How it works: The durable synthetic chemicals, which resist degradation by repelling oil and water and withstanding high temperatures, have been used in hundreds of nonstick, water- and oil-repellent, and fire-resistant products.

• If the chemicals enter the environment through production or waste streams, they can resist breaking down for hundreds of years while contaminating water sources and bioaccumulating in fish, wildlife, livestock, and people.

• Research has shown that reducing levels of PFAS in drinking water or switching to other water distributors will likely require municipalities to invest millions of dollars into new infrastructure and incur ongoing maintenance costs.
• For example, officials in Cape Fear allocated $46 million and a recurring annual operating cost of $2.9 million to upgrade a treatment plant designed to filter PFAS from drinking water.

Meanwhile, 3M — a major PFAS producer — has also reached a tentative settlement worth at least $10 billion with water providers, Bloomberg reported Friday.

• News of a potential settlement came just days before the company's first federal trial over PFAS pollution claims.
• Facing extensive PFAS litigation — including a lawsuit from the Dutch government — 3M announced in December 2022 that it would stop manufacturing and using the chemicals by the end of 2025.
• "The parties are making material and significant progress toward a resolution of this matter, and have jointly requested a continuance," a 3M spokesperson said in a statement to Axios on Monday.
• "As we have previously disclosed, we are in active, ongoing, and confidential mediation sessions."
