Firefighting foam company reaches $750 million PFAS settlement

By Shannon Kelleher

The company Tyco Fire Products today reached a $750 million settlement to help resolve claims related to its firefighting foam, which allegedly contaminated drinking water systems with harmful PFAS chemicals for decades.

Once the settlement is approved, an estimated 7,000 to 8,000 US public water systems could receive money to treat contaminated drinking water, said Joe Rice, co-lead attorney for the plaintiffs with the Motley Rice law firm. Water systems that test positive for PFAS by May 15 may be eligible to benefit from the settlement.

“$750 million towards this problem, that is a huge contribution,” said Rice.

Tyco, a subsidiary of Johnson Controls, does not admit liability or wrongdoing by agreeing to the settlement.

The announcement builds on last summer’s landmark settlements from the companies 3M, Dupont, and others, which could total up to nearly $14 billion to assist affected water systems as they test for and clean up PFAS contamination. 3M’s settlement received final approval April 1.

Earlier this week, US regulators announced the nation’s first legally enforceable limits for levels of six toxic per- and polyfluoroalkyl substances (PFAS) in drinking water, a move the US Environmental Protection Agency (EPA) says should prevent thousands of deaths and reduce serious illnesses in people across the country.

Unsafe levels of PFAS contaminate global water sources, study finds

By Shannon Kelleher

A large part of the world’s surface waters and groundwater contains toxic PFAS chemicals at levels higher than regulators consider safe for drinking water, according to a new analysis of data from more than 45,000 water samples collected from around the world.

The data points to Australia, China, Europe and North America as hotspots for contamination by per- and polyfluoroalkyl substances (PFAS), although the authors suggest this may be skewed due to higher levels of sampling in these regions.

The findings, which were published April 8 in the journal Nature Geoscience, come as regulators in the United States prepare to set the first enforceable drinking water limits for certain types of PFAS. Many US states and other countries have already set regulations for PFAS in drinking water.

“I was surprised to find out the large fraction of source waters that are above drinking water advisory recommendations,” Denis O’Carroll, an engineering professor at the University of New South Wales in Australia and an author of the study, said in a press release.

The number of samples considered unsafe was higher in countries that have stricter PFAS drinking water guidelines and regulations. In Canada, which has one of the strictest recommendations for PFAS in drinking water, 69% of groundwater samples had levels that surpassed that country’s threshold, while only 6% of samples from the European Union failed to meet its criteria.

PFAS in firefighting foam linked to testicular cancer in new study

By Grace van Deelen

A study of over 1,000 Air Force servicemen shows that exposure to firefighting foam containing PFAS may be linked to a higher risk of developing testicular cancer.

The research, led by scientists from the National Institutes of Health (NIH), a federally funded research center, adds to a collection of scientific work investigating the links between certain kinds of PFAS and a range of human health harms.

The new study specifically looked at PFAS as an ingredient in aqueous film-forming foams (AFFFs) used on military bases, and analyzed PFAS exposures of Air Force servicemen who worked regularly with AFFF for years.

The findings may give new credence to mounting lawsuits from military veterans claiming PFAS exposure in firefighting foam made them sick while manufacturers hid the health risks. Thousands of other lawsuits are pending against PFAS manufacturers 3M and DuPont, among other companies, alleging they spread harmful PFAS throughout the environment despite knowing of risks to human health.

“We were still under the perception that firefighting foam was safe,” said Kevin Ferrara, a retired former Air Force firefighter who used AFFFs on a regular basis for 15 years during his military career. While Ferrara has never had testicular cancer, he suffers from other health issues he believes are linked to PFAS exposure. He says that no one ever told him or his colleagues that the firefighting foam might have posed a health risk, and they didn’t usually take extra precautions to avoid direct contact with the foam.

“Now we know the truth,” he said.

Q&A: Tackling PFAS-contaminated water with technology

Amid growing evidence of the health risks associated with per- and polyfluoroalkyl substances (PFAS), a wave of technology companies are developing strategies to remove toxic PFAS chemicals from drinking water and wastewater.

The moves come as the US Environmental Protection Agency (EPA) is taking action to crack down on PFAS pollution, particularly on two of the most widely used PFAS, which have been linked to an array of health problems.

Cleaning up the contamination is a significant challenge, however; one recent study warned that PFAS contamination is so ubiquitous globally that advanced technological intervention is needed.

One tech company seeking to tackle the problem, 374Water, has created waste processors called AirSCWOs that use an oxidation method to convert toxic sludge – including PFAS-contaminated waste streams – into clean water.
