Regenesis - Model SourceStop -Colloidal Activated Carbon
A patented colloidal activated carbon material that locks PFAS contamination in place at the source, preventing migration and reducing risk. SourceStop stops PFAS from leaching into groundwater, protecting downgradient receptors. Its advanced colloidal activated carbon (CAC) technology penetrates and coats soils for fast, long-lasting treatment. Available in liquid or solid form, SourceStop offers an easy, cost-effective solution for PFAS sites.
PFAS contaminated soils in the source area
SourceStop Solid is an engineered aggregate combining colloidal activated carbon (CAC) and powdered activated carbon (PAC). Its particles are designed to be low-dust, highly wettable, and easy to handle with standard site equipment.
When mixed into impacted soils, the aggregate rapidly disintegrates on contact with water, releasing sub-2-micron colloidal carbon that penetrates and coats soil particles. This process immobilizes PFAS, reducing leachability and preventing migration into underlying groundwater.
SourceStop Solid is ideal for remediating PFAS-impacted soils in source areas. It can be used independently or combined with SourceStop Liquid or PlumeStop for complete source and plume control.
