Study outlines long-term PFAS solution using colloidal activated carbon for airport site remediation
A new study featured in the Winter 2022 issue of the REMEDIATION Journal assessed the factors affecting in situ colloidal activated carbon (CAC) remediation of PFAS at airport sites.
The research study, titled Longevity of colloidal activated carbon for in situ PFAS remediation at AFFF-contaminated airport sites, was authored by Dr. Grant Carey, an expert groundwater modeler and President of Porewater Solutions. Coauthors include researchers at the University of Waterloo, Carleton University, and Rick McGregor, leading environmental remediation practitioner and President of InSitu Remediation Services, Ltd.
Aqueous film-forming foam (AFFF) releases at military and civilian airport sites are among the leading causes of PFAS contamination of groundwater, creating some of the most serious health risks to communities and fueling a worldwide search for the most effective remedies to reduce PFAS exposure. Further, the massive scope of the PFAS problem has created an urgent need for developing low-cost and sustainable treatment methods to reduce the exposure risk. The patented CAC material, commercially known as PlumeStop®, has recently emerged as a solution to meet this need.
