Remediating, Insuring, and Litigating PFAS Claims Abstract PFAS are a group of chemicals found in a variety of products (e.g., Teflon®) and have been used widely in industrial and environmental processes (e.g., oil recovery, firefighting). They do not break down, and over time can accumulate in the body and the environment. While largely no longer used in the United States, they continue to be used internationally. Studies have shown they have adverse health effects on humans and animals. In this article the authors discuss the history and impact of PFAS, insurance coverage for claims relating to PFAS contamination, the practice of “insurance archaeology,” maximizing insurance coverage, and, finally, existing and anticipated litigation arising from environmental damage and bodily harm from PFAS.
