Abstract: Poly- and perfluoroalkyl substances (PFAS) are a large group of organic contaminants that have been detected nationally in the aquatic environment. Two PFAS compounds, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), have been observed in >95% of the blood samples collected during multiple U.S. national surveys at health-relevant concentrations. Contaminated drinking water is a major source exposure to PFAS for the general public. The U.S. EPA has recently set a drinking water advisory on the combined level of PFOA and PFOS at 0.070 μg/L, making removal of PFAS from drinking-water sources a priority issue. The goal of this project is to develop an innovative treatment system that can effectively and practically remove PFAS from landfill leachate and groundwater. The results of this project have important implications for technological improvements in water purification. Water treatment plants, the water industry, water resources personnel, and the broader education and research communities who are concerned about PFAS contamination would benefit from the results of this proposal.
