Featuring Dr. Mark L. Brusseau, professor, University of Arizona recorded on April 2, 2024, from 12 – 1:30 PM (Central).
PFAS have been determined to be present in soils at numerous sites, originating from a variety of source inputs. One critical concern for sites with PFAS-impacted soils is potential leaching through the vadose zone and subsequent impacts to groundwater. This webinar will discuss the physical-chemical properties and mass-partitioning processes that influence the retention and leaching of PFAS in the vadose zone. Results from bench-scale experiments, mathematical-modeling studies, and field investigations will be used to illustrate the unique transport properties of PFAS. A recent case study that investigated the presence of PFAS in a managed aquifer recharge (MAR) site will be presented. Implications of the unique transport and fate properties of PFAS for MAR applications will be discussed.
