Regenesis - Model PlumeStop -Colloidal Activated Carbon
A patented colloidal activated carbon technology that adsorbs groundwater contaminants, including PFAS and CVOCs, directly in situ—immobilizing them and reducing risk.PlumeStop is an injectable colloidal activated carbon technology that rapidly captures and biodegrades a wide range of contaminants including PFAS and CVOCs. It distributes easily under low pressures to effectively halt contaminant migration, addresses back-diffusion, and protects sensitive receptors.
PlumeStop is a patented in situ remediation technology that uses sub-2-micron activated carbon particles to create a thin, permeable film on aquifer solids. This film rapidly adsorbs groundwater contaminants, including PFAS and CVOCs, reducing their mobility and exposure risk while maintaining natural aquifer permeability.
Once applied, PlumeStop coats aquifer materials with a highly adsorptive carbon layer that captures dissolved contaminants directly in place. For PFAS, this immobilization prevents plume migration. For CVOCs, PlumeStop can be paired with electron donors such as AquiFix or S-MicroZVI to stimulate sustained biodegradation, which regenerates sorption sites and extends treatment performance.
PlumeStop is effective at a wide range of contaminated sites, including industrial facilities, airports, federal installations, and military bases. It is well-suited for projects requiring rapid risk reduction, long-term protection, and a sustainable alternative to pump-and-treat.
