Eliminate the Risk of PFAS with Colloidal Activated Carbon

In situ remediation with colloidal activated carbon eliminates risk of PFAS contamination in soil and groundwater at a low-cost. By coating flux zones of an aquifer with colloidal activated carbon, a permeable sorption barrier is created in situ, purifying groundwater as it passively migrates. PFAS constituents from up-gradient source zones are rapidly sorbed to the carbon and removed from the mobile dissolved phase. By removing PFAS from the mobile phase, the route of exposure to down-gradient receptors is eliminated, thereby eliminating the down-gradient public health risk associated with PFAS.
