Remedial Approaches for Passive Management of PFAS Contaminated Groundwater, Surfacewater, Stormwater, and Sediment

With the focus of PFAS active PFAS remediation being on protecting drinking water, there have been a number of locations with ongoing PFAS exposure due to shallow soil, groundwater, and surface water impacts. Such locations may not have a regulated level for which remediation may be targeted, yet the present an opportunity to demonstrate passive technologies that can mitigate ongoing PFAS exposure risk. This work proposes several approaches for managing sites with impacted soil, sediment, surface and/or stormwater with a passive treatment solution based on a combination of proven amendments for PFAS removal and a delivery mechanism that can allow for permeable treatment in a low-cost fashion.
