EPA Tools & Resources Webinar

Chemical Risk Assessment for PFAS in Biosolids

Wednesday, June 21, 2023

3-4 pm ET

EPA committed in the agency’s PFAS Strategic Roadmap to conduct a biosolids risk assessment for two PFAS compounds, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), in biosolids. EPA’s Office of Water will discuss the current work related to assessing risk due to the presence of PFOA and PFOS in biosolids. The presentation will cover the regulatory context through which EPA regulates chemical contaminates in biosolids, a brief overview of PFAS monitoring, and actions that have occurred in the states. This will be followed by a discussion of the exposure assessment framework EPA has developed to evaluate impacts from biosolids through ingestion of drinking water, crops, milk and meat and how that framework may be implemented for PFOA and PFOS.
