Colloidal Activated Carbon for In Situ Remediation of PFAS: A Review of Multiple Case Studies
Chad Northington, P.E., Southeast District Manager, REGENESIS
With the increasing awareness to the widespread contamination of PFASs coupled with their resistance to degradation, there is a need for new, low cost strategies to address these contaminants. The ability to implement an in situ barrier of activated carbon to amend the effective foc of an aquifer and increase the natural retardation factor for these contaminants is an appealing strategy to manage these plumes. This risk-based approach removes PFAS from the mobile phase and eliminates the route of exposure to downgradient receptors. This presentation reviews data from multiple field sites where colloidal activated carbon has been utilized to remediate PFAS contamination.
