A breakthrough has been achieved with in-well fractionation, eliminating the need for water extraction and aboveground treatment. PFAS circulating well remedial design has been successfully implemented through demonstrations and full-scale applications, confirming its effectiveness in reducing PFAS concentrations while safeguarding valuable groundwater resources. This PFAS treatment technology builds upon the established circulating well concepts which have seen successful deployment at sites worldwide, with tailored adaptations to address the unique characteristics and chemical properties of PFAS compounds.  In this innovative approach, the remediation process centers on boosting foam production within the circulating well (fractionation) and subsequently extracting the foam to the surface. This eliminates the necessity of pumping large volumes of water to the surface, a key distinction from traditional foam recovery methods. Moreover, besides PFAS compounds, this alternative technology has proven effective in treating a wide range of constituents.  Multiple PFAS circulating wells treatment systems have been installed and operated successfully. The concentrations of PFAS in the recovered foam have consistently surpassed subsurface water concentrations. Substantial reductions in concentration levels have been verified through water samples collected from the remedial wells and monitoring locations. Field results at a full site implementation in NJ , including groundwater and foam concentrations along with mass reduction data, will be presented and discussed.
