A key component of a company’s risk management function is to keep a close eye on new and developing sources of liability and to put in place appropriate insurance to respond in the event those liabilities ripen. In recent years, there has been a significant increase in legal and regulatory attention on per- and polyfluoroalkyl substances, more commonly known as “PFAS” or “forever chemicals.” PFAS are used in countless applications, and many companies across the country bear potential liability, from chemical companies to manufacturers to retailers to corporate end users. PFAS-related enforcement is focused on remedying impacts to both the environment and human health. Importantly, a company’s liability for PFAS-related contamination or bodily injury may be covered under historic general liability policies and/or modern-day pollution liability policies. As regulation and litigation relating to these ubiquitous substances continues to surge, corporate policyholders with potential exposure should be proactive to examine their insurance portfolios and position themselves for potential insurance coverage in the event they become a PFAS liability target.
