This 2026 updated course provides a comprehensive overview of PFAS site management including 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. This 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, F-53B, ADONA, and GenX related chemicals such as hexafluoropropylene oxide dimer acid (HFPO-DA). 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. Federal drinking water standards and drinking water treatment technologies are also covered.

Course Reviews (4.8/5):

Summary: This course provides a comprehensive overview of the transport, fate, and attenuation of metals in soil and groundwater using the "Scenarios Approach". The Scenarios Approach was developed by Savannah River National Laboratory to provide a quick and easy framework for improving the assessment and remediation of inorganic contaminated sites. The Scenarios Approach is based on the interpretation of plume geochemistry, geochemical gradients, and specific inorganic contaminant behavior in various geochemical settings (e.g., Cr(VI) instability under low redox conditions). Understanding metal behavior within various geochemical conditions provides an improved method for predicting metal contaminant transport and fate, and implementing effective remediation strategies. The course focuses on metals in soil and groundwater, and is also applicable to sediment, stormwater, and surface water.
