PFAS – also known as PFOAs – are a family of highly toxic, fluorinated chemicals found in more than 2,800 communities across the United States, including much of Long Island. PFAS have been used mainly in industrial settings since the 1940s, and the family includes more than 5,000 chemicals, linked to cancer and other significant health issues. The two of the most common, PFOA and PFOS, are used to make everyday items such as nonstick pans, carpets and firefighting foam. Many communities in Long Island are well over the recommended safe level. Hicksville, where Simply PÜR Water Filtration is located, has 15,198x the recommended PFOA amounts in its water.
