Featured Case Study | PlumeStop Shuts Down Pump and Treat System at Superfund Site

This case study reviews a large federally operated Superfund site where REGENESIS Remediation Services (RRS) completed a large-scale PlumeStop application to eliminate the risk of exposure to chlorinated solvents. The PlumeStop treatment prevented plume migration, protecting nearby community drinking water wells. This sustainable approach eliminates the massive carbon footprint created by outdated pump-and-treat approaches.

Amentum, a leading American governmental and commercial services contractor, is the responsible party’s contractor. Amentum has worked with the client at this site for years, providing oversight and management of their contracting partners. The project’s sensitive nature required an enhanced awareness of health, safety, and security issues and seamless coordination between RRS, Amentum, and their client.

Press Release | REGENESIS’ PlumeStop Technology Finalist in Prestigious Fast Company Awards

We are excited to share that REGENSIS’ PlumeStop colloidal activated carbon technology has been recognized as a Finalist in Fast Company’s Innovation by Design Awards for 2023. With proven efficacy in treating groundwater contaminants including PFAS and chlorinated solvents, this patented solution eliminates the risk of “forever chemicals” and tackles the urgent need to resolve groundwater contamination for communities impacted globally. PlumeStop PFAS treatment transforms underlying geology into a purifying filter and prevents PFAS from migrating further.

Article | Combined Remedy Rapidly Achieves Targets to Address Chlorinated Solvent Impacts

This article reviews an active industrial facility in Southern California impacted by PCE and TCE, where a technology-based solution from REGENESIS quickly reduces CVOC concentration below targets, priming the site for future closure. The remedy included a permeable reactive barrier (PRB) in which the co-application of PlumeStop and S-MicroZVI combines a massive surface area for contaminant sorption with the rapid degradation of CVOCs to non-toxic end products such as ethene, ethane, and carbon dioxide. These end products, which do not bind to carbon, free up PlumeStop’s sorption sites on the aquifer matrix. As PlumeStop is regenerated, the PRB’s treatment capacity is further extended.

Case Study | PlumeStop and S-MicroZVI Effectively Treat CVOCs to Expedite Site Closure

In addition to the RemTec article, this case study provides a more in-depth overview on an active industrial facility in Southern California where PlumeStop and S-MicroZVI successfully treated CVOC contamination. The combined remedy quickly reduced CVOC concentrations below targets, priming the site for future regulatory closure. The responsible party retained Roux, a leading environmental remediation consultant, to complete the remediation project. Specifically, the remedy needed to (1) reduce CVOCs in soil, soil vapor, and groundwater to background contamination levels; (2) minimize disruption to the site tenant occupying the building; (3) coordinate with offsite property owners to complete the work; and (4) complete all work within established budgets and timeframes.

Case Study | PlumeStop Eliminates PFAS for Seven Years

This case study reviews the first known full-scale in situ PFAS treatment worldwide completed in 2016 at a manufacturing and former firefighting training site in Ontario, Canada, where aqueous film-forming foams (AFFF) were used. A single application of PlumeStop resulted in the reduction of contaminant concentrations to non-detect levels, with reductions maintained for 7+ years since the injection. Remediation company IRSL collected critical treatment zone information to ensure a successful application. An independent fate and transport modeling expert predicts that PlumeStop will halt PFAS migration out of the treatment zone for more than 60 years, preventing exposure risk and reducing liabilities for the site owner.

Upcoming Webinar | Novel Electron Donor Development: Supporting Evidence Through Genomics and Metabolomics

Dr. Paul Erickson, Director of Research & Development at REGENESIS, will be a guest presenter for a technical webinar presentation with Microbial Insights on Tuesday, September 12th at 9am pacific/12pm eastern. Dr. Erickson will present on the first-ever solid, micron-scale colloidal electron donor designed to be compatible and co-injected with PlumeStop. The development and field testing of AquiFix included the use of Microbial Insights’ QuantArray™ to demonstrate the efficacy of the new electron donor technology. Dr. Erickson will provide an overview of the development and field-testing of AquiFix in addition to how his research and development scientists incorporate microbial testing into the design and testing processes at REGENESIS.
