Case Study | Treatment Solution for TCE Saves Client $380,000

This case study reviews a former manufacturing facility in Indianapolis that had released high levels of chlorinated solvents into the groundwater, creating a large plume. Wilcox Environmental Engineering, Inc., a leading engineering and consulting firm based in Indianapolis, was hired by the responsible party to investigate the site. After evaluating the remedial options, Wilcox worked with REGENESIS to design a solution for in situ remediation of the TCE plume using biogeochemical reduction in the onsite plume area and sorption-enhanced chemical reduction in the offsite plume. This combined in situ remediation solution rapidly mitigated a threat to a nearby river and saved the client $380,000.

Case Study |  Pilot Projects at Two UK Airports Demonstrate Successful PFAS Remediation

This case study reviews two airport sites in the United Kingdom where the groundwater was contaminated with PFAS that had originated from the use of Aqueous Film Forming Foams (AFFF). An in situ approach using colloidal activated carbon permeable reactive barriers (PRB) combined with successful pilot study results allowed for regulatory permission for full-scale PlumeStop PRB installations on both sites. The PlumeStop PRB converts the contaminant flux zones in the treatment area into subsurface filters, which adsorb incoming contamination and stop offsite migration. This prevents risk to downgradient receptors, removes offsite liability from the site owner and allows Enhanced Natural Attenuation (ENA) of the downgradient PFAS plume.

Case Study | PlumeStop Treats PFAS and Protects Island Community Resources

This case study reviews a site at Martha’s Vineyard Airport where a PlumeStop permeable reactive barrier (PRB) was used to treat PFAS. PlumeStop PRBS filter PFAS out of groundwater, sorbing the contaminants onto the aquifer matrix and preventing further plume migration. In less than four months, PlumeStop has eliminated PFAS mass flux immediately downgradient of the barrier and significantly reduced PFAS concentrations further away, as monitoring continues. The cost-effective and sustainable solution to remove PFAS exposure risk provides an alternative to expensive and ineffective pump & treat (P&T) systems.

Sustainable PFAS treatement

Video | Low-Cost, Sustainable PFAS Treatment, Explained

This video explains a solution to eliminate PFAS risk at a fraction of the cost of pump and treat methods. Pump and treat mechanical systems require significantly more money to operate, produce millions of tons of carbon emissions, and represent what remediation experts have coined “remediation in perpetuity.” A newer, more cost-effective, sustainable and guaranteed proven method is replacing these pump and treat mechanical systems for PFAS. PlumeStop Colloidal Activated Carbon works below ground surface, filtering out PFAS contaminants as they migrate with the natural flow of groundwater.

Download Case Study | PetroFix PRB Prevents Offsite Risk at Gas Station

This case study reviews an active gas station in the United Kingdom where dissolved phase contamination at high concentrations in groundwater migrated beyond the site boundary, resulting in a potential off-site liability. An in situ permeable reactive barrier (IPRB) using PetroFix colloidal activated carbon was installed to prevent offsite risk. Environmental consulting firm SLR Consulting partnered with REGENESIS to design and apply the solution, which quickly met site objectives. The PetroFix IPRB was the most sustainable option for the site. Substantial energy savings were made when compared with operating a groundwater pump and treat system. The project was completed for <£100K ($127,300 USD), with only minimal disruption to site operations.

Remediating petroleum contamination

Video | A Practical Approach to Remediating Petroleum Hydrocarbon Plumes

This video explains a simple, proven and cost-effective approach to quickly remediate sites with petroleum contamination. PetroFix is a micron-scale colloidal activated carbon fluid with electron acceptors injected under low pressure to sorb and biodegrade petroleum hydrocarbons in groundwater. Engineered to provide immediate and long-lasting results for a variety of sites including retail gas stations and industrial petroleum spills, PetroFix is a cost-effective in situ treatment for petroleum hydrocarbon contamination.
