SAN CLEMENTE, Calif.–(BUSINESS WIRE)–REGENESIS, the recognized leader in soil and groundwater remediation solutions and vapor intrusion mitigation technologies, is proud to announce a major milestone in the effective treatment of PFAS contaminants using its patented colloidal carbon amendment, PlumeStop®. Scott Wilson, CEO and president of REGENESIS, announced in a recent webinar that PlumeStop has been applied or is planned for application on more than 100 PFAS sites globally and will continue to grow in adoption due to its proven efficacy and acknowledged cost-competitiveness compared to other PFAS treatment approaches.

Proven to Reduce PFAS to Regulatory Clean-up Levels on All Applications Completed

PlumeStop PFAS treatments have proven successful with the target PFAS compounds reduced and maintained below their regulatory clean-up levels on all applications completed to date including industrial manufacturing facilities, Department of Defense sites, U.S. EPA Superfund sites and more. Compared to ex situ PFAS treatment approaches, such as pump and treat, PlumeStop in situ treatments do not generate new waste streams that transfer the liability to landfills or incineration facilities; and PlumeStop project life-cycle costs are a fraction of any other treatment technology available today.

Widely Adopted to Eliminate PFAS Risk

Since the introduction of PlumeStop in 2014, environmental experts have shown great interest in the science behind the innovative technology, which features the unique use of micron-sized carbon particles suspended in water through a proprietary dispersion chemistry. This innovation allows PlumeStop to flow into the subsurface at low pressure and achieve consistent, reliable distribution that is unparalleled in the industry. Already proven as an effective treatment method for groundwater contaminants such as chlorinated solvents and petroleum hydrocarbons, PlumeStop is now being widely adopted to eliminate the dangers of PFAS.

Ideal for Airports, Industrial Sites and Residential Communities Impacted by PFAS Contaminants

PlumeStop’s micron-scale activated carbon technology is designed to inhibit the spread of contaminant plumes and is the only in situ amendment effectively addressing PFAS risk. It can be applied using low-pressure injection techniques, avoiding the excessive installation, operation and maintenance costs incurred with pump and treat systems. With the ability to remove PFAS and other contaminants rapidly from groundwater, it is ideal for sites like airports, active industrial operations and residential communities where a pump and treat system is either cost-prohibitive or disruptive to infrastructure.

Transforms Groundwater Aquifer into Purifying Filter to Prevent PFAS Migration

PlumeStop involves injecting and coating the subsurface soil grains with one to two micron-sized activated carbon particles, which chemically sorb the PFAS compounds and other organic contaminants from the groundwater as it naturally flows through a treatment zone. Employing a proprietary organic polymer dispersion chemistry that prevents agglomeration, PlumeStop’s activated carbon particles can pass through the smallest soil pores, achieving wide distribution in the subsurface. This treatment process transforms the underlying geology into a purifying filter, preventing the PFAS from migrating further. PlumeStop treatments for PFAS are designed to last for decades with a single application as corroborated through independent, peer-reviewed, third-party studies.

Sustainable, Cost-Effective, Less Disruptive and Faster

Abinash Agrawal, Ph.D., a groundwater and soil remediation professor at Wright State University, was quoted in a recent article acknowledging PlumeStop as “cost-effective, less disruptive and faster than other treatment methods currently available.”

EWG Reports Drinking Water for 200 Million Americans Affected

The Environmental Work Group (EWG), a non-profit, non-partisan organization focused on the environment, reports PFAS contaminants have been found in the drinking water of over 200 million Americans and the issue is one of the environmental challenges the Biden administration is committed to addressing in the new term.

“Our commitment to developing groundbreaking environmental solutions is unparalleled in the industry and we are excited about the impact PlumeStop is having on sites where PFAS poses a risk to communities globally,” explains Wilson. “We expect PlumeStop to continue to grow in demand as community awareness of this pollutant increases and the regulatory community begins to establish and enforce cleanup standards.”
