Regenesis launches proprietary PFAS remediation solution

San Clemente, California-based soil and groundwater remediation solutions company Regenesis has launched SourceStop, a proprietary remediation solution that eliminates the risk of per- and polyfluoroalkyl substances (PFAS) in soil and groundwater.

Eliminating PFAS exposure risk has become a global priority, with more than 57,000 PFAS-contaminated sites in the U.S. prompting new regulations that aim to safeguard public health and the environment.

Regenesis says its newest offering is able to target highly contaminated soils in the source area, neutralizing the risk from these contaminants quickly and effectively. Combined with PlumeStop, a colloidal activated carbon technology treating PFAS in groundwater, these technologies enable full-spectrum treatment of PFAS contamination in the ground.

SourceStop is a highly engineered technology that uses 1-2 micron-sized particles of activated carbon, available in liquid and solid form. It works by preventing the leaching of soil contamination and halting the migration of PFAS in groundwater, eliminating the risk to nearby communities. SourceStop’s formulation of activated carbon enables distribution by penetrating and coating impacted soils. SourceStop can be customized to the meet the needs of any impacted site and can be used in conjunction with PlumeStop for what the company says is the world’s first end-to-end, in situ PFAS remediation approach.

“We developed SourceStop to address a critical gap in the market for a rapid, low-cost solution that targets soil and groundwater contamination at the source,” Regenesis President and CEO Scott Wilson says. “By adding SourceStop to our toolbox, we are providing an efficient, resilient and adaptive technology for use at defense sites, airports and industrial manufacturing sites, eliminating the significant risk of PFAS while helping to reduce and preserve resources.”

PFAS do not degrade naturally, and because of this contaminated sites have historically relied on pump-and-treat systems, resulting in contamination being brought to the surface for treatment and disposal in landfills.

Regenesis says SourceStop has been proven effective in the field, with leaching of PFAS from soil found to be reduced by more than 99 percent within days and eliminated to “below laboratory detection limits” in samples collected after six months.
