• Reduced dissolved-phase PCE concentrations by 99.96% and TCE concentrations by more than 99.8% within one year, effectively controlling contaminant migration and protecting off-site receptors.
• Combined rapid plume stabilization with ongoing treatment, leveraging PlumeStop for immediate sorption and S-MicroZVI for abiotic degradation within a reactive treatment barrier.
• Delivered a practical in situ solution for a challenging site, overcoming heterogeneous geology, shallow groundwater conditions, and high contaminant concentrations while maintaining operations at an active industrial facility.
• Completed installation in approximately two weeks and within budget, providing an efficient, cost-effective approach to managing chlorinated solvent impacts and reducing off-site migration risk.

An active industrial facility in Rio de Janeiro, Brazil faced the challenge of preventing a high-concentration chlorinated solvent plume from migrating beyond its property boundary. REGENESIS implemented a compact in situ permeable reactive barrier (PRB) using PlumeStop® colloidal activated carbon and S-MicroZVI® sulfidated colloidal zero valent iron, providing immediate contaminant mass flux control and long-term treatment within the subsurface. The solution was installed quickly, on budget, and delivered dramatic reductions in contaminant concentrations within just one year.
