Per- and polyfluoroalkyl substances (PFAS), known for their grease-resistant, water-repellent and insulating properties, include a large category of chemicals used for decades in consumer, commercial and industrial applications. Over the past decade, PFAS have become a major regulatory and litigation target for state and federal agencies and plaintiffs’ firms. The trend does not appear to be changing. Product manufacturers, importers, distributors and retailers across numerous industries face increasing risks based on their current and former manufacture, import, sale, use and disposal of products containing PFAS.
