Per- and polyfluorinated alkyl substances (PFAS) are a large group of synthetic fluorine-containing chemicals. PFAS are particularly problematic because of their high mobility, resistance to breakdown, and ability to bioaccumulate. They are used in a wide variety of industrial and commercial products such as textiles, leathers, firefighting aqueous film forming foams (AFFF), metal plating, semi-conductors, paper and food packaging, coating additives, cleaning products, and pesticides.
PFAS can be found in virtually any environmental medium, as well as in living organisms, food, breast milk, and human blood serum worldwide. Certain compounds are suspected to be related to adverse health effects such as high cholesterol and blood pressure, thyroid disfunction, elevated uric acid associated with gout, altered liver function, certain types of cancer, and low infant birth weight.
Though there are thousands of PFAS compounds, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are the most researched to date. MDEQ adopted the 70 parts per trillion drinking water health advisory level for PFOS and PFOA combined, established by the EPA. The EPA also calculated residential soil screening levels, and established water quality standards for publicly owned treatment works (POTW) facilities for drinking water and non-drinking water for PFOS and PFOA. Regulations will likely continue to expand and evolve with further research as the knowledge base grows.
