    SourceStop Reduces PFAS by >99% Below Belgian Factory

    Innovative pilot project is first of its kind in Europe

    Case Study Highlights

    • PFAS leaches into groundwater beneath source area on industrial facility in West Flanders, Belgium

    • SourceStop Liquid, a colloidal activated carbon (CAC) technology designed for penetrating and permanently coating impacted soils in PFAS source areas, was applied in a proof-of-concept pilot.

    • Over five months of monitoring, total PFAS concentrations in groundwater decreased by more than 99%, demonstrating broad effectiveness in rapidly removing both short- and long-chain PFAS from the dissolved phase.

    Read the Case Study

    SourceStop® Liquid, a colloidal activated carbon (CAC) technology, was applied as a proof-of-concept pilot to reduce PFAS migration beneath a source area at a West Flanders, Belgium textile manufacturing facility. Over five months of monitoring, total PFAS concentrations in groundwater decreased by more than 99%, demonstrating an effective strategy for eliminating PFAS leaching into groundwater below this and other PFAS source areas. Monitoring will continue and the results and information gathered will enhance the design of the full-scale application, offering a better understanding of the anticipated outcomes and associated costs. The full-scale remediation plan is targeted for completion in the first half of 2025.
