This Seattle Brownfield redevelopment case study showcases the transformative impact of advanced site characterization and targeted in situ remediation technologies. Faced with complex subsurface contamination from decades of dry cleaning operations, the project team leveraged high-resolution imaging and precision application of REGENESIS solutions—including S-MicroZVI and 3-D Microemulsion—to achieve a remarkable 99.9% reduction in chlorinated solvent concentrations. This innovative approach not only accelerated the path to regulatory closure but also delivered substantial cost savings, paving the way for successful redevelopment into affordable housing and retail space.

• Exceptional Remediation Performance:
  The combined use of S-MicroZVI and 3-D Microemulsion technologies reduced total chlorinated volatile organic compounds (CVOCs) in groundwater by 99.9%, with most monitoring wells reaching or approaching non-detect levels—demonstrating the effectiveness of targeted in situ treatment.
• Significant Cost Savings:
  By integrating advanced site characterization (GeoTrax Survey) and focusing remediation only on active contaminant transport pathways, the project team achieved an estimated $3.7 million in cost savings compared to conventional broad-scale approaches.
• Accelerated Redevelopment and Regulatory Closure:
  The precision and efficiency of the REGENESIS solution enabled rapid progress toward regulatory closure without excavation or infrastructure removal, positioning the site for redevelopment into mixed-income housing and retail—delivering both environmental and community benefits.
