Two of the most commonly encountered perfluorinated compounds (PFCs) are perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), both of which are considered emerging contaminants and potential carcinogens. These are persistent once in groundwater and do not readily degrade or metabolise. Treatment of these plumes has always been difficult and costly.

With the development of PlumeStop®, REGENESIS® is able to offer a new tool to address these challenging contaminant plumes.

REGENESIS R&D has tested the adsorption efficacy of PlumeStop with individual adsorption isotherms (PFOA and PFOS) measured in the laboratory. The isotherms were fit according to the Freundlich model and the parameters were then used to model the expected treatment efficiencies with PlumeStop. The results show effective capture of the contaminant plume through adsorption (see figures on this page).
