Litigation over per- and polyfluoroalkyl substances (PFAS) in the United States continues to garner news coverage and generate headlines. While these suits began as claims against manufacturers of PFAS itself, they are now beginning to appear further down the supply chain in an enormous variety of industries. With PFAS found in common household products from food wrappers to cosmetics and nonstick cookware to medical equipment, a wide array of policyholders now find themselves staring down the barrel of PFAS products liability lawsuits. Insurance companies are also poised to challenge whether liability insurance coverage for these claims exists and have already started attempting to rely on an old favorite provision to do so: the pollution exclusion. Fortunately for policyholders, courts have long held that the pollution exclusion is inapplicable for product liability claims like these.
