EPA Releases Draft Interim Guidance for PFOS PFOA in Groundwater
WASHINGTON –Today, the U.S. Environmental Protection Agency (EPA) released draft interim guidance for addressing groundwater contaminated with perfluorooctanoic acid (PFOA) and/or perfluorooctane sulfonate (PFOS) for public review and comment. This is a key component of the agency’s PFAS Action Plan. These draft recommendations will help protect human health in communities across the country by providing clear and consistent guidance on addressing PFOA and PFOS in groundwater under federal cleanup programs. This information has been requested by other federal agencies and the states and could be used by other federal, state and tribal cleanup programs.
“Today, we are delivering on one of our most important commitments under the PFAS Action Plan,” said EPA Administrator Andrew Wheeler. “This interim guidance will support actions to protect the health of communities impacted by groundwater that contains PFOA and PFOS above the 70 parts per trillion level, and is a potential source of drinking water. This is a critical tool for our state, tribal, and local partners to use to address these chemicals.”
EPA developed this guidance based on the agency’s current scientific understanding of PFAS toxicity, including the agency’s PFOA and PFOS health advisories. The recommendations may be revised as new information becomes available.
EPA has opened a docket for a 45-day public comment period. The draft guidance describes EPA’s interim recommendations for screening levels and preliminary remediation goals (PRGs) to inform final cleanup levels for PFOA and/or PFOS contamination of groundwater that is a current or potential source of drinking water.
