Testing and Implementation of a Passive Barrier/In Situ Treatment System for Surface and Shallow Groundwater

Addressing the release of PFAS into the environment from impacted stormwater or groundwater-to-surface water discharge remains an important goal for state-led PFAS efforts. For such releases, active ex-situ treatment (pump and treat with ion exchange/GAC) may not be technically or economically feasible for several reasons, such as intermittent/seasonal flows, restrictive access, etc. Independent lab scale batch and column testing were undertaken to evaluate the effectiveness and feasibility of a novel adsorption technology to mitigate PFAS release via stormwater and groundwater-to-surface water discharge, and to provide important data towards field scale applications. The preliminary configurations, conceptual approach, and performance data from the pilot-scale evaluation of the system will be presented. The feasibility of a novel adsorbent system at addressing PFAS migration via stormwater/surface water/groundwater was evaluated at the lab and field scale.
