THE IN SITU REMEDIATION OF A PFAS PLUME USING COLLOIDAL ACTIVATED CARBON
McGregor, R. | 2019 Real Property Institute of Canada (RPIC) Federal Contaminated Sites Regional Workshop, 4-5 June, Halifax, Nova Scotia. 20 slides, 2019
PFOA and PFOS were detected in a shallow aquifer at a site in Canada at concentrations up to 3,300 ng/L and 1,500 ng/L, respectively. Colloidal activated carbon (AC) was applied over a 26-month period using direct push technology to remove PFOA and PFOS to levels at or below the analytical detection limit of 20 ng/L. Post-injection analyses showed that all PFAS were below method detection limits. Detailed examination of cores taken post-injection indicated that the colloidal AC was successfully distributed within the target zone of the impacted aquifer and was measured up to 5 m away from the injection point. http://rpic-ibic.ca/images/2019_FCSRW/presentations/The_In-Situ_Remediation_of_a_PFAS_Plume_Using_Colloidal_Activated_Carbon.pdf
