Each and everyday the impact of PFAs in our environment comes more and more to the forefront of our industry. Legislatures and scientists alike are working tirelessly to establish remedial standards, develop more accurate methods of analysis, and identify potential remedial solutions.
The people over at REGENESIS are amongst those searching to find a way to deal with sites that have been impacted by this “forever chemical.” They have found that colloidal activated carbon can be used as a low-cost method of eliminating PFAS risk. By coating the 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.
