Why Target PFAS Source Zones?

Targeting PFAS Source Zones:

• Accumulation of PFAS in the soil creates significant reservoirs of contaminant mass.
• These plumes represent a risk to downgradient environmental and human receptors such as potable drinking water wells, surface water bodies and the aquifer itself. These risks generate potentially significant liabilities for the landowners on which the source areas are located.
• The PFAS source-plume system can be treated through a targeted application of SourceStop in the source zone.

SourceStop® is a highly effective treatment for PFAS-contaminated soil and groundwater in source areas. It works by preventing the leaching of soil contamination and halting the migration of PFAS in groundwater, eliminating the risk to downgradient receptors. Available in solid and liquid forms, SourceStop offers a highly adaptable solution that can be customized to accommodate a wide range of site conditions and application-specific needs. SourceStop is applied to the soil vadose zone, capillary fringe, and groundwater to immobilize PFAS at their original point of release. SourceStop’s unique formulation contains our patented colloidal activated carbon (CAC) technology, which achieves unsurpassed distribution in a targeted treatment zone by penetrating and permanently coating impacted soils in PFAS source zones. SourceStop treatment can be combined with downgradient PlumeStop barriers to immediately halt the migration of PFAS plumes. Together, SourceStop and PlumeStop offer the world’s first full-spectrum solution to remediate the PFAS source-plume system in soil and groundwater.
