Arlington County Statement on EPA’s Proposed PFAS Regulations

Published on March 15, 2023

The U.S. Environmental Protection Agency (EPA) announced Wednesday proposed regulations for six types of per- and polyfluoroalkyl substances (PFAS) in drinking water. 

PFAS are a family of hundreds of man-made chemicals used in a wide variety of commercial, industrial, and household products including cookware, toiletries, paints, fabrics and fire-fighting foams. PFAS have been manufactured for at least 50 years.

Arlington has been closely following these proposed regulations and working with regional partners on this issue to ensure the County’s water supply continues to meet or exceed all U.S. Environmental Protection Agency and Virginia Department of Health safety standards. Prior testing of Arlington’s drinking water by the Washington Aqueduct and Virginia Department of Health have shown low levels of some PFAS compounds. None of the test results have exceeded the proposed regulatory limits, and most of the test results have not detected the PFAS compounds in our drinking water.
