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.

“A huge victory for public health”: EPA set limits on PFAS toxins in drinking water

By Shannon Kelleher

US regulators on Wednesday put in place the nation’s first legally enforceable limits for levels of six toxic PFAS chemicals in drinking water, saying the moves should prevent thousands of deaths and reduce serious illnesses in people across the country.

The rule is designed to reduce exposure to these per-and polyfluoroalkyl substances (PFAS) – also called “forever chemicals” – for about 100 million people nationwide, according to the US Environmental Protection Agency (EPA). Exposure to PFAS has been linked to “deadly cancers, impacts to the liver and heart, and immune and developmental damage to infants and children, the EPA said.

“Today we can celebrate a huge victory for public health in this country,” Rob Bilott, a lawyer who has become famous for his work against PFAS, said in a statement. Bilott has spent decades pushing for PFAS regulations and to hold PFAS manufacturers accountable for releasing the dangerous chemicals into the marketplace.

“It should never have taken this long to address such serious threats to public health and our environment,” Bilott said, noting that he first alerted the EPA to the presence of PFAS in US drinking water more than twenty-three years ago.

The new rule sets a limit of four parts per trillion (ppt) for two types of PFAS – perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), which are both known to be particularly hazardous.

The EPA acknowledged that there is “no level of exposure to these contaminants without risk of health impacts, including certain cancers,” and said it was setting a “non-enforceable health-based goal,” at zero for PFOA and PFOS.

Warnings of a “wave of lawsuits” as PFAS exemption debated

By Shannon Kelleher

Representatives of US water and waste systems told US lawmakers this week that hundreds of such operations across the nation could face unintended and overwhelming liabilities unless they are exempted from a proposal that would designate two types of per- and polyfluoroalkyl substances (PFAS) as hazardous substances.

The rule proposed by the Environmental Protection Agency (EPA) sets up “multiple avenues to drag innocent parties into extremely costly and complex litigation,” Michael Witt, a lawyer speaking on behalf of a coalition of water groups, told members of the US Senate Committee on Environment and Public Works in a hearing Wednesday.

Witt was one of multiple witnesses to address the committee on the hotly contested issue of how the government should address widespread PFAS environmental contamination. The EPA said in 2022 that it was preparing to designate perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) because they present “a substantial danger to human health or welfare and the environment.”

Such a designation allows the government to order responsible parties to clean up the environmental contamination and bear the costs of mitigation. The “polluter pays’ model is a core principle of CERCLA.

The debate now underway is about whether to provide an exemption from liability for “passive receivers” of PFAS – entities that don’t make or use PFAS but wind up with the chemicals in their water, land and waste. The EPA has said it won’t assign liability to passive receivers, but Witt and others speaking at the hearing said there is still concern that such entities could become embroiled in lawsuits over chemicals they never used or produced.

Texas farmers, watchdog group demand EPA act on PFAS in farm fertilizer

By Shannon Kelleher

In the wake of fresh evidence that US farms are being poisoned by PFAS-laden fertilizers, a watchdog group and two Texas farm families said Thursday they plan to sue regulators to try to force protective actions.

The Environmental Protection Agency (EPA) has violated the Clean Water Act by failing to regulate at least 12 per- and polyfluoroalkyl substances (PFAS) in treated sewage sludge (biosolids) applied to agricultural lands, allege Public Employees for Environmental Responsibility (PEER) and the farmers in a notice of intent to sue sent Feb. 22 to EPA Administrator Michael Regan. Studies have linked these particular PFAS chemicals to asthma, disrupted thyroid hormones, immune suppression, kidney problems, lung issues in children, and other health effects, the letter says.

The agency has also unlawfully failed to include in its regular biosolids reports at least 18 additional PFAS chemicals that scientific studies indicate are present in biosolids, PEER and the farmers allege.

PEER and the farmers will sue the EPA within 60 days if the agency does not take immediate action, said PEER executive director Timothy Whitehouse in the notice of intent to sue.

“EPA has deemed it acceptable for biosolids containing PFAS and other known toxic chemicals to be applied directly to soil as fertilizer, where these man-made contaminants then build up in the environment, exacerbating the PFAS contamination crisis,” wrote Whitehouse. “This is not protective of human health or the environment.”

“Because there are no standards, farmers, ranchers, and gardeners have no warning that they are potentially poisoning their soil, water, livestock, and pets with these biosolid fertilizer products,” Kyla Bennett, director of science policy for PEER, said in a press release. “Prompt, responsible regulatory action by EPA would prevent untold damage and heartache.”

Research ramps up but PFAS pollution remains tough to tackle

By Shannon Kelleher

As researchers rush to tackle global contamination from a class of toxic chemicals known as PFAS, a new study demonstrates a novel way to detect the substances in wastewater – but also underscores how far scientists are from figuring out how to effectively overcome this worldwide threat to human and environmental health.

The new method makes use of a sensor to identify one type of per- and polyfluoroalkyl substances (PFAS) called perfluorooctanoic acid (PFOA) in heavily contaminated water based on changes in light emissions from metals on the device’s surface, according to a Jan. 16 study in the journal Analytical Chemistry. The researchers plan to develop the early model in to a portable device, according to a press release.

Current PFAS detection methods take place in a laboratory using a tool called a mass spectrometer, which charges molecules in a sample and then accelerate them using magnetic or electric fields so that scientists can identify them.

“Existing approaches are time-consuming,” said Zoe Pikramenou, a professor at the University of Birmingham in the United Kingdom who is an author of the study. “Our approach offers significant advantages of greater speed, ease of analysis, and reduced cost over currently-used methods.”

The prototype can so far only measure one PFAS chemical out of thousands. And although the sensor appears to be sensitive enough to illuminate PFAS in industrial wastewater, it may take another decade before the technology can be used for drinking water, which contains much lower levels of the chemicals, said Pikramenou.

Many other promising new technologies to detect so-called “forever chemicals”, which do not naturally break down, remain in the early stages of development. The Biden administration has called on federal agencies to restrict PFAS from entering US water, air, land, and food; set goals for the government to better assess and reduce PFAS exposure; clean up existing pollution; and expand health effects information.

Ohio PFAS class action lawyers slam US judges; seek rehearing

By Shannon Kelleher

A federal appeals court should grant a rehearing in a class action lawsuit filed against the makers of toxic PFAS chemicals after a panel of three federal judges disregarded legal precedent and misstated crucial facts in rejecting claims of liability alleged against PFAS makers, according to a petition filed by plaintiffs’ lawyers in the closely watched legal battle.

The request for rehearing comes after last month’s ruling by the Cincinnati, Ohio-based 6th US Circuit Court of Appeals, which reversed a lower court’s approval of the lawsuit brought on behalf of Ohio residents who want PFAS makers 3M, DuPont and others to pay for medical monitoring and studies that will analyze the health impacts of PFAS contamination the residents have been exposed to. The plaintiff’s attorneys have requested either a panel rehearing; a hearing before all judges of the court; or permission for the plaintiff to refile.

Lead plaintiff Kevin Hardwick worked as a firefighter for 40 years and used PFAS-containing foams at work. He alleges that ten companies, including chemical giants 3M, DuPont, and related companies, caused his blood -and the blood of other Ohio residents – to become contaminated with potentially dangerous levels of PFAS chemicals. The judges who rejected the allegations said in their opinion that Hardwick could not trace the chemicals in his blood back to the ten defendants, citing “the thousands of companies that have manufactured chemicals of this general type over the past half-century.”

In the filing by plaintiffs’ lawyers on Monday, the lawyers for the class action said the judges were factually wrong on multiple fronts, including stating that there are thousands of PFAS manufacturers. One of the PFAS toxins found in Hardwick’s blood is perfluorooctane sulfonic acid (PFOS). PFOS has only been made by defendant 3M, for instance, a fact not even disputed by 3M, the petition states. Another type of PFAS found in his blood was perfluorooctanoic acid (PFOA).

“Defendants do not dispute that they caused PFOA (and other PFAS) to be created and deposited into human blood. Nor do they dispute that that these toxins did not exist before Defendants created them,” the Hardwick petition states. The defendants additionally have been identified by the US EPA as “known makers” of PFOA, according to the petition for rehearing.

PFAS may disrupt bone development in children and young adults, study finds

By Shannon Kelleher

Exposure to a widespread, toxic chemical called PFOS may interfere with bone development in children and young adults, potentially putting them at higher risk for osteoporosis and other bone problems later in life, according to a new study that focused mainly on Hispanic individuals from southern California.

Perfluorooctane sulfonic acid (PFOS), a widespread type of per- and polyfluoroalkyl substances (PFAS), was associated with lower bone mineral density in a group of 328 overweight Hispanic children and in a group of 158 young adults of mixed ethnicity. The study, published Dec. 6 in the journal Environmental Research, was unique in that it tracked associations between bone density and PFAS blood serum levels over time.

“Existing research had established associations between PFAS and bone health, but previous studies, most of them only collected information at one time point from participants,” said Emily Beglarian, a PhD student at the University of Southern California’s Keck School of Medicine and the lead author of the study. “Additionally, many existing studies were focused on non-Hispanic, white participants and many focused on older adults.”

Although Hispanic people are at high risk for developing osteoporosis as adults, they are often not included in research on bone health, said Beglarian.

There are over 12,000 PFAS chemicals, which do not break down naturally and have been found in at least 45% of US tap water, according to the US Geological Survey, and in the blood of about 97% of Americans, according to the US Centers for Disease Control and Prevention (CDC). Exposure to PFAS has previously been linked to numerous health problems, including kidney cancer, testicular cancer, thyroid disease, thyroid cancer, and ulcerative colitis.

Chemical found widely in the environment causes cancer, global experts determine

By Shannon Kelleher

A group of global scientific cancer experts this week classified a widespread chemical known as PFOA as carcinogenic to humans, confirming decades of research, and building on concerns about human and animal exposure to that chemical and to the larger class of manmade substances that are commonly known as “forever” chemicals because of their persistence in the environment. Separately, the experts deemed a related chemical called PFOS as possibly carcinogenic to humans.

The classifications, published Thursday in The Lancet Oncology, were determined by a working group of 30 experts from around the world through the International Agency for Research on Cancer (IARC), an arm of the World Health Organization (WHO). The experts convened in Lyon, France Nov. 7-14 to review published literature on the health risks of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). Both are types of per-and poly fluoroalkyl substances (PFAS).

“This latest action highlights and reaffirms the concerns we have been raising for decades that these man-made ‘forever chemicals’ present a serious threat to human health, mandating that appropriate steps be taken to prevent and address exposures,” said Rob Bilott, an environmental lawyer for the Ohio-based firm Taft Law who has spent over two decades exposing the dangers of PFAS chemicals.

In classifying PFOA as carcinogenic, the IARC scientists said they found “sufficient” evidence for cancer in experimental animals exposed to PFOA and “strong” evidence that the chemical affects gene expression and immune response in humans exposed to PFOA. They also found limited evidence for cancer in humans, identifying a link to renal cell cancer and testicular cancer.

The scientists said that the research shows PFOS is “possibly” carcinogenic to humans. They said they found strong mechanistic evidence that the chemical affects gene expression and immune response in exposed humans, along with several other key characteristics of carcinogens. They also found limited evidence linking PFOS to cancer in experimental evidence but ‘inadequate evidence’ linking it to cancer in humans.

It remains to be determined how, or if, the new classifications may impact thousands of lawsuits that are pending in US courts against PFAS makers DuPont and 3M. The companies have been sued by individuals as well as by drinking water utilities and municipalities over alleged harms tied to PFAS contamination.

On Monday, a US appeals court turned back a large class action lawsuit brought on behalf of Ohio residents, finding there was not sufficient proof that the companies caused the exposure alleged in the case. Lead plaintiff Kevin Hardwick, who worked as a firefighter for 40 years and used PFAS-containing foams, brought the suit in 2018, alleging that the companies caused his blood to become contaminated with potentially dangerous levels of PFAS chemicals. Hardwick asked for a panel of scientists to study the effects of PFAS in his body and for medical monitoring.

PFAS chemicals linked to thyroid cancer, human data suggests

By Shannon Kelleher

Exposure to some per- and polyfluoroalkyl substances (PFAS) may increase thyroid cancer risk, according to a study published Tuesday.

The analysis, which compared blood samples from 88 people who developed thyroid cancer with samples from people who did not, is the first to document an association between PFAS and thyroid cancer, which had been previously hypothesized. Past research has linked these endocrine-disrupting chemicals to thyroid disease, a condition in which the gland produces too many or too few hormones. The new research adds to a growing list of health problems linked to PFAS, including kidney cancer, testicular cancer, ulcerative colitis, high cholesterol, and hypertension during pregnancy.

The study, which looked at eight different types of so-called “forever chemicals,” found that doubly high levels of perfluorooctanesulfonic acid (PFOS) in the blood corresponded with a 56% higher risk for thyroid cancer diagnosis. The PFAS chemicals perfluorononanoic acid (PFNA), perfluorooctylphosphonic acid (PFOPA), and perfluorohexanesulfonic acid (PFHxS) were also found to be associated with thyroid cancer.

“Although preliminary, this is an important study highlighting the risk of thyroid cancer derived from PFAS contamination of water and soil,” said Luca Chiavato, a professor of endocrinology at the University of Pavia in Italy who was not involved with the study.

Historic 3M PFAS settlement gets preliminary court approval

By Shannon Kelleher

A federal court on Tuesday granted preliminary approval for a “landmark” $12.5 billion payout by chemical conglomerate 3M to resolve claims in a class action lawsuit and help public drinking water providers remove toxic per- and polyfluoroalkyl substances (PFAS) from communities around the United States.

The court approval comes a week after DuPont and related companies received preliminary approval for a $1.185 billion settlement that similarly addresses class action claims over toxic PFAS contamination in US water systems. Together, the deals mark the largest drinking water settlements in history.

Both settlements relate to water system contamination by PFAS in aqueous film-forming foam (AFFF), used as a firefighting agent and widely used by military and civilian airports as well as municipal fire departments.

The AFFF litigation is one aspect of more extensive and ongoing litigation against 3M and DuPont that blame the companies for knowingly contaminating the environment with PFAS for decades despite evidence that the substances pose a risk to human health. Lawyers representing plaintiffs in the litigation have uncovered internal corporate records dating back to the 1960s revealing corporate concerns about PFAS that were not shared with the public or regulators.

“These new proposed settlements for public water providers in the AFFF litigation represent not only historic amounts of potential recoveries for victims of PFAS contamination, but also reflect the decades of work our team has undertaken to make sure the information these companies had – but withheld – as to the threat these ‘forever chemicals’ pose to human health and the environment is finally revealed to the public, and that the proper parties are held financially responsible for the enormous damage caused,” plaintiffs’ attorney Rob Bilott, who has led PFAS litigation for more than 20 years, said in a press release.
