Underwriters Wary of PFAS Amid ‘Superstorm’ of Litigation, Regulation

As litigation and regulation increase around per- and polyfluoroalkyl substances (PFAS), insurance underwriting is tightening across lines. Insurance professionals who specialize in PFAS say insurers are mandating coverage exclusions and, in some cases, declining to write liability policies at all in PFAS-exposed industries.

Robin Kelliher, environmental solutions group counsel at USI, described the current insurance landscape as being hit by a “superstorm” of factors related to PFAS.

“The insurance underwriters are just seeing lawsuits, lawsuits, lawsuits,” she said, and they don’t know how those lawsuits are going to play out.

Industrial manufacturing company 3M reached a $10-plus billion settlement in June 2023 with a collection of U.S. public water systems to resolve PFAS water pollution claims. Around the same time, Dupont reached an estimated $1.19 billion settlement with a collection of U.S. public drinking water systems.

A new EPA rule and recent Insurance Services Office changes are also shaping how underwriters view the risk. Just a few months ago, the EPA set a limit on how much PFAS can be in drinking water. And, last year, ISO published endorsements broadly excluding PFAS-related claims for insurers to use in CGL policies.

“It touches everything,” Kelliher said of PFAS. “And the carriers are seeing the lawsuits. Their insureds are being sued, and they’re submitting them as claims. That’s why the carriers are reacting the way they are. Because it’s coming from all different avenues.”

The EPA reports that PFAS are widely used, long-lasting chemicals, the components of which break down very slowly over time. Studies have shown that exposure to the chemicals may be linked to harmful effects in humans and animals.

PFAS can be found in drinking water, fire extinguishing foam, food, personal care products and more. Per the EPA, it can be found in the air and soil. On its website, the EPA said current peer-reviewed studies link certain levels of exposure to reproductive and developmental effects, as well as an increased risk of some cancers and reduced immune system ability.

Lisa Williams, global head of casualty at Zurich Insurance Group, explained that PFAS exposure predominantly tends to fall in two major categories: premises exposure and products liability exposure.

A recent USI report said litigation is prompting the reassessment of approaches to PFAS underwriting, coverage, risk management and claim handling. The report says that most insurers are mandating exclusions on general liability and products liability policies on all renewal accounts, regardless of industry or exposure to loss, but especially manufacturing, hospitality, retail and owners of real estate.

USI anticipates that finding PFAS coverage in the environmental insurance marketplace will be more difficult for product exposure, including supply chain and distribution risks and site-specific risks.

Kelliher said PFAS surfaced on pollution liability underwriters’ radar around 2018—and as state regulations on the coasts began to surface, carriers began to pay attention. Underwriters used to be more willing to write the exposure, she said, but that has changed in the past year because of the liability that stems from the Comprehensive Environmental Response, Compensation, and Liability Act.

“When the EPA started talking about adding PFAS as a hazardous substance under CERCLA, then, all of a sudden, the underwriting scrutiny became tenfold more,” Kelliher said. “And we started seeing PFAS exclusions being added to our pollution policies.” Increased litigation is also creating what she described as a “reactive” market.

Kelliher has seen exclusions extend beyond the pollution liability line and into contracting operations, product liability and more. She sees a connection between this and ISO’s approval of PFAS-specific exclusions for commercial general liability and umbrella policies.

“So, this year, all of our clients are starting to see, on their standard lines of business like their GL policies, a PFAS exclusion,” she said. That “is really causing a lot more havoc in the marketplace.”

Kelliher said she doesn’t know if carriers are adding PFAS exclusions carte blanche to standard policies, “but if you’re a manufacturer, you’re seeing a PFAS exclusion. And it’s for your products, so that becomes really problematic for our insureds.”
