In situ PFAS treatment with PlumeStop®

PlumeStop is the only in situ remedial technology proven to eliminate the environmental risk of PFAS in groundwater. PlumeStop is liquid, colloidal activated carbon that is injected under low pressure into PFAS plumes to prevent further contaminant migration. PlumeStop coats the aquifer matrix within the contaminant flux zones with a micron-scale layer of activated carbon. This creates a purifying filter in the subsurface, which will sorb the PFAS, removing it from the groundwater. This allows low regulatory standards to be rapidly achieved and maintained long-term, eliminating PFAS risk to downgradient receptors. The short video on the right-hand side explains how PlumeStop works.
