• Rapid and Lasting Results: Achieved a 98.5% reduction in TCE within one month, with a 99.7% reduction sustained over 4.5 years of monitoring.
• Regulatory Approval for Low-Pressure Injection: S-MicroZVI’s unique chemistry allowed for safe, low-pressure application, preventing subsurface fracturing and meeting strict regulatory requirements.
• Facilitated Property Sale and Redevelopment: Successful remediation cleared the way for the site’s sale and future use, transforming a stalled brownfield into a valuable asset.

This case study reviews a former manufacturing site in Fullerton, CA, where a trichloroethylene (TCE) plume contaminated the groundwater and prevented the sale of the brownfield site. By combining large-diameter auger excavation with the injection of 50,000 gallons of sulfidated, micro-scale zero valent iron (S-MicroZVI®), the project achieved a rapid and sustained reduction in TCE concentrations—over 99.7% in the treatment zone—enabling regulatory approval, site sale, and redevelopment. This innovative, low-pressure injection approach delivered long-term results while overcoming challenging site conditions and regulatory constraints.
