Colloidal Activated Carbon for in situ Remediation of PFAS: A Low-Cost Risk Mitigation Strategy
Chad Northington, P.E., Southeast District Technical Manager, REGENESIS
With the increasing awareness to the widespread contamination of PFAS coupled with their resistance to degradation, there is a need for new, low-cost strategies to address these contaminants. The current remediation method is pump and treat systems equipped with activated carbon or a resin, however the associated costs can be exorbitant. This presentation reviews data from multiple field sites where colloidal activated carbon has been utilized to remediate PFAS contamination. Further important questions, including cost comparisons, the long-term efficacy, and design considerations, will also be addressed.
