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. The strong carbon-fluorine bond that allows for the manufacture of oil- and water-resistant products also makes it difficult for PFAS to break down in the environment. This is why many consider PFAS “forever chemicals.”
