On April 25, 2019, the U.S. Environmental Protection Agency (EPA) released its Draft Interim Recommendations to Address Groundwater Contaminated with Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS) for public review and comment. The comment period ends on June 10, 2019.
PFOA and PFOS are two substances within the much larger group of per- and polyfluoroalkyl substances (PFAS), man-made chemicals that historically were widely used and presently are used across the country every day in a wide array of consumer and industrial products. Water resources known to have been contaminated by PFOA and PFOS are associated with releases from manufacturing sites, industrial sites, fire/crash training areas, and industrial or municipal waste sites where products are disposed of or applied. PFAS are highly resistant to degradation and are extremely persistent in the environment as well as in organisms, including human beings.
