Harnessing the Power of Bubbles to Remove PFAS from Plumes and Source Zones

The presentation will summarize the results and learnings of the first in-situ implementation of foam fractionation for removal of PFAS from source soils and groundwater.  The trial utilized two paired recirculation wells to remove 107 g of PFAS from the treatment zone over the 12 weeks of the trial.
