All the statements about PFAS are correct. PFAS are a group of man-made chemicals used in various products for their water-resistant and non-stick properties. However, they are widespread contaminants in drinking water and are known to be persistent organic pollutants that do not easily degrade in the environment. Their persistence leads to bioaccumulation in animal bodies, raising concerns for human health and wildlife.
