Description

We will develop two methods for the in situ remediation of PFAS contamination: downhole foam fractionation for in situ groundwater treatment, and in situ fluidisation for soil treatment, both separately and in combination. In these methods, PFASs are removed in the form of a foam, which is extracted as a liquid concentrate. The second method also washes fine particles - to which PFASs will be bound - from the soil. Preliminary results suggest that both techniques could enable PFAS removal efficiencies of greater than 90%, providing entirely new methods for the aggressive removal of PFAS from contaminated source zones. This project will develop the two methods by column and tank testing, and a field pilot trial at a PFAS-contaminated site.
