Performance Summary: In Situ Colloidal Activated Carbon Treatment of PFAS-Impacted Groundwater
There is a rapidly growing need to identify technically practicable and cost-effective remedies to treat PFAS substances in groundwater and reduce the exposure risk to potential human and environmental receptors downgradient of PFAS-release sites. One remedial method is the in situ chemical sorption treatment of PFAS by colloidal activated carbon (CAC), with several Department of Defense-funded studies examining the treatment process now underway. To date, 17 in situ PFAS-contaminated groundwater remediation treatments using CAC have been installed. While most of these have occurred within one to two years, five sites have at least two years of performance data following CAC injection. This performance summary provides technical details on the design and application for PFAS treatment and summarizes the post-application groundwater results relative to baseline conditions at these five sites. These results will help inform groundwater remediation practitioners, project stakeholders, and regulators when considering remediation options for addressing PFAS in groundwater.
