Fire-fighting activities using aqueous film-forming foams (AFFFs) have caused widespread contamination of per-, and polyfluoroalkyl substances (PFAS) in the environment. Because polyfluoroalkyl substances account for a significant portion in AFFF formulations, understanding the transformation of these chemicals is crucial for accurately assessing the contamination extent and fate. Dr. Shan Yi will describe her research on using a combination of analytical methods to investigate the biotransformation of a principle PFAS in common AFFF formulations under both aerobic and anaerobic conditions. This session will also give you an overview of the current knowledge on PFAS composition found in AFFF formulations, as well as PFAS biotransformation and its implications on site investigation and remediation efforts.
