CNN: What exactly are PFAS chemicals? They are in nonstick surfaces; they’re used in firefighting foams, protecting packages from grease, and waterproofing of carpets and your clothing. Because of the structure of these chemicals, they’re able to have these (nonstick, water-repellent and temperature-regulating) properties. Water is a common route of exposure — drinking water from your municipal water sources in your home are contaminated with PFAS chemicals. There are new ones being created all the time, so we don’t even know all the potential PFAS chemicals that are out there.
