What are PFAS contaminants?
Per- and polyfluoroalkyl substances (PFAS) are a class of thousands of synthetic chemicals used to make products resistant to water, heat, and stains. PFAS, often referred to as “forever chemicals,” do not easily break down in the environment and are difficult to destroy.
Are PFAS still used?
