Video | PlumeStop Used to Treat PFAS and Protect Community Resources at Martha’s Vineyard Airport

Martha’s Vineyard Airport is used by a significant number of general aviation aircraft with a high number flying in during the summer months. Over the years, as required by the FAA, the airport has conducted fire training exercises releasing AFFF fire-fighting foams in an area adjacent to the runway. Beginning in November 2018 as awareness and concern about PFAS in AFFF were increasing, Martha’s Vineyard Airport proactively identified an approach to contain AFFF testing solutions. As a result of the AFFF releases, the groundwater has been impacted with PFAS contaminants that are now being proactively treated by the airport. Tasked with evaluating available options to address the PFAS impacts, TetraTech worked with REGENESIS to develop a remedial design incorporating permeable reactive barriers emplaced in situ using PlumeStop colloidal activated carbon.

Video | PlumeStop Cost-Effectively Treats CVOCs at Secure Government Facility

A large, secure government facility in the Mid-Atlantic region was designated a Superfund site under CERCLA. The high-security area had been used as a salvage yard where activities requiring cleaning solvents, among other volatile materials, had leached into the groundwater, creating a large plume in the sandy geology. Amentum, a leading American government and commercial services contractor, is the responsible party’s contractor and has worked with the client at this location for years, providing oversight and management of their contracting partners throughout this and other environmental remediation projects. A remedial approach was designed to reduce and degrade the CVOC contaminants while protecting against the groundwater plume’s migration beyond the site’s boundaries.

Video | FluxTracers Precisely Target Contaminants and Save $380,000 in Project Costs

This video reviews a former industrial site in downtown Indianapolis where chlorinated solvents in groundwater were threatening to impact the nearby White River. Wilcox Environmental, a leading consulting firm based in Indianapolis, collaborated with REGENESIS on a remediation solution incorporating PlumeStop and S-MicroZVI to treat the contaminants. FluxTracer®, a contaminant flux mapping tool from REGENESIS, was employed to identify the target treatment zones carrying contaminant mass. The use of FluxTracers enabled the team onsite to deliver PlumeStop and S-MicroZVI precisely to treat target contaminants, and also saved the client $380,000 in project costs.

Featured Article | Results Document the Biodegradation of Contaminants from Colloidal Activated Carbon

This article published in Remediation Technology provides an abbreviated overview of two laboratory experiments and a fieldwork demonstration that showed evidence for the biodegradation of contaminants from colloidal activated carbon (CAC). The CAC technologies developed by REGENESIS are often paired with biostimulating electron acceptors or donors to destroy adsorbed contaminants. Laboratory and field research on these technologies has shown the ability of bacteria to fully mineralize adsorbed contaminants and increase in population in the presence of CAC and electron acceptors or donors added to the system.

Article | New Study Confirms a More Sustainable Approach to Treat PFAS

This article published in Water Online discusses a new study outlining a long-term PFAS solution using colloidal activated carbon (CAC) at airport sites. The sustainable in situ CAC approach is poised to save billions of dollars in pump-and-treat system installation, operation & maintenance costs and eliminate millions of tons of harmful greenhouse gas emissions that power them. Over 40 in situ CAC treatments have been installed, including recent installations at airports and airfields across the U.S. and Great Britain. Additionally, the U.S. Department of Defense is funding several SERDP laboratory and field research projects to study the technology, as interest in the approach continues to surge.

Webinar Recording Now Available | In Situ Treatment of PFAS at the Air-Water Interface within a Source Zone using PlumeStop

In this webinar, we were pleased to have special guest speaker Rick McGregor, President of InSitu Remediation Services Ltd. His presentation discussed the in situ treatment of PFAS at the air-water interface within a source zone using PlumeStop. He was joined by Gareth Leonard, Managing Director of REGENESIS Europe, who discussed in situ treatment of PFAS using colloidal activated carbon to eliminate PFAS risk at a low cost. The recording is now available.
