ORIN achieved over 99% reduction in chlorinated solvents using innovative combination of BAM and ABC+ technology through strategic injection methods.

ORIN conducted large scale treatment of groundwater contaminated with chlorinated solvents using BAM, a pyrolized cellulosic material, and ABC+, a soybean EVO mixed with zero valent iron. BAM was mixed with water and injected through 14 DPT points and ABC+ was mixed with water and injected through 6 DPT points encompassing MW-04 and MW-07. 20 points were injected around each well for a total of 40 points, 2,800 gallons of BAM and 1,200 gallons of ABC+. A barrier wall was made around MW-44 with a mixture of BAM and ABC+ DPT points. During injection activities, BAM and ABC+ were observed in MW-04 and MW-44. Treatment extended from 20 feet below ground surface (ft bgs) to approximately 30 ft bgs.

A large-scale groundwater remediation project has demonstrated remarkable success in treating chlorinated solvents through an innovative combination of BAM and ABC+ technologies.

The Treatment Strategy

The team implemented a comprehensive dual-treatment approach:

  1. BAM Treatment:
    • Pyrolized cellulosic material
    • 2,800 gallons injected
    • 14 DPT injection points
    • Strategic placement around monitoring wells
  2. ABC+ Treatment:
    • Soybean EVO mixed with zero valent iron
    • 1,200 gallons injected
    • 6 DPT injection points
    • Complementary placement strategy

Implementation Details

The project utilized sophisticated delivery methods:

  • Total of 40 injection points
  • Treatment depth: 20-30 feet below ground
  • Barrier wall installation around MW-44
  • Combined BAM/ABC+ mixture for optimal results
  • Verified treatment distribution through well observations

Outstanding Results

Post-treatment monitoring revealed exceptional success:

  • MW-04: 95.3% reduction in all COCs
  • MW-07: 99.9% reduction
  • MW-44: 99.8% reduction
  • Results confirmed through three sampling rounds

Key Success Factors

Several elements contributed to the project’s effectiveness:

  1. Strategic combination of treatment technologies
  2. Precise injection point placement
  3. Optimal treatment depth targeting
  4. Comprehensive monitoring program
  5. Barrier wall integration
