A patented colloidal activated carbon material that locks PFAS contamination in place at the source, preventing migration and reducing risk.
Engineered for rapid results and long-term treatment.
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. SourceStop offers an easy, cost-effective solution for PFAS sites.
SourceStop successfully reduces PFAS leaching by 99% at Michigan national guard site
What does it treat?
PFAS contaminated soils in the source area
What is it?
SourceStop is an engineered microaggregate using colloidal activated carbon (CAC) to treat PFAS. Its particles are designed for better distribution, to be low-dust, and are easy to handle with standard site equipment.
How does it work?
When mixed into impacted soils, the microaggregate 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 discharge into underlying groundwater.
Is it right for my site?
SourceStop is ideal for remediating PFAS-impacted soils in source areas. It can be used independently or combined with PlumeStop for complete source and plume control.
