EPA announces two steps to address PFAS in wastewater

The US Environmental Protection Agency (EPA) has announced two steps to address per- and polyfluoroalkyl substances (PFAS) in wastewater.

Under the first step, EPA issued a memorandum that details an interim National Pollutant Discharge Elimination System (NPDES) permitting strategy in order to address PFAS in EPA-issued wastewater permits.

As per the second step, the agency informed about the progress in developing new analytical methods to test for PFAS compounds in wastewater and other environmental media.

After the validated analytical methods are finalised, these steps will ensure the commencement of federally-enforceable wastewater monitoring for the substances.

EPA administrator Andrew Wheeler said: “Better understanding and addressing PFAS is a top priority for EPA, and the agency is continuing to develop needed research and policies. For the first time in EPA’s history, we are utilizing all of our program offices to address a singular, cross-cutting contaminant and the agency’s efforts are critical to supporting our state and local partners.”

EPA assistant administrator for water David Ross said: “Managing and mitigating PFAS in water is a priority for the Office of Water as we continue our focus on meeting 21st century challenges. These actions mark important steps in developing the underlying science and permitting techniques to address PFAS in wastewater where the discharge of these chemicals may be of concern.”

EPA, in collaboration with the US Department of Defense, is developing analytical methods to test for PFAS in wastewater and other environmental media, such as soils.

The agency is issuing a list of 40 PFAS chemicals that are the subject of analytical method development.

EPA expects the multi-lab validated testing for PFAS to be finalised next year.
