Course Reviews (4.8/5): 
This course provides a comprehensive overview of the transport, fate, and remediation of per- and polyfluoroalkyl substances (PFAS) in soil, surface water, and groundwater. 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 common forms detected in the environment including the ionized perfluoroalkyl acids (PFAA) such as perfluorooctanoate (PFOA), perfluorooctanesulfonate (PFOS), PFAA precursors, and newer PFAS including perfluorobutanesulfonate (PFBS), fluorotelomer substances, F53B, ADONA, and GenX related chemicals such as hexafluoropropylene oxide (HFPO) dimer acid. The course then focuses on more advanced topics including PFAS transport, fate, site characterization, analytical methods, and effective remediation strategies for soil, surface water, and groundwater.
