THE IN SITU REMEDIATION OF PFAS-IMPACTED GROUNDWATER USING INJECTABLE ACTIVATED CARBON

This study involved the application of colloidal activated carbon at a site in Canada. PFOA and PFOS were detected in groundwater at concentrations up to 3,300 ng/L and 1,500 ng/L, respectively, before remediation. Colloidal activated carbon was applied using direct-push technology, resulting in the removal of the PFOA and PFOS to concentrations at and below the analytical detection limit (> 20 ng/L) over a 21-month period. Analysis showed that all PFASs analyzed were below their method detection limits. Examination of post-injection cores indicated that the colloidal activated carbon was successfully distributed within the target zone and was measured up to 5 m away from the injection point.
