Why We Need a New Approach to PFAS Remedial Investigations
Summary
Remediating per- and polyfluoroalkyl substances (PFAS) in groundwater presents numerous challenges, necessitating a site characterization workflow that differs from the industry standard. In this presentation, learn about a more strategic, effective approach to remediating complex sites, one that incorporates the use of 3D subsurface mapping — by way of Environmental Sequence Stratigraphy (ESS) — to target the PFAS groundwater sampling program and address critical data gaps. Implementing this approach reduces the cost and duration of PFAS investigations and provides a process-based conceptual site model that can be used to assess risk and design efficient remedial solutions for PFAS.
