This course provides a comprehensive overview of per- and polyfluoroalkyl substances (PFAS) transport, fate, and remediation. PFAS have been in use since the 1940s, are highly toxic, resist degradation, and are becoming increasingly regulated. The training begins with a review of PFAS sources, toxicity, and the common forms detected in the environment including perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), newer GenX related chemicals including hexafluoropropylene oxide (HFPO) dimer acid, and perfluorobutane sulfonic acid (PFBS). The course then focuses on more advanced topics including PFAS transport and fate, site characterization methods, and effective remediation strategies. Common PFAS site types and regulatory status will also be discussed.
