Former Co-op—Central Nebraska

ORIN successfully treated Benzene contaminated groundwater utilizing ORIN’s patented Bioavailable Absorbent Media (BAM). ORIN utilized DPT in order to effectively cover the injection area around MW-1 . A vacuum truck was utilized during chemical injection to remove highly contaminated groundwater and to provide hydraulic control. Eleven injection points received a combined total of 1,100 gallons of treatment chemistry.

The Challenge

The site presented specific treatment needs:

• High benzene concentration: 7.544 mg/L
• Site-specific target: 6.970 mg/L
• Single well focus area (MW-1)
• Need for precise treatment
• Regulatory compliance requirements
• Path to site closure

The Solution: Targeted BAM Implementation

The team executed a precise treatment strategy:

1. Treatment Design:
   • 11 strategic injection points
   • 1,100 gallons total treatment volume
   • DPT application methodology
   • BAM technology deployment
   • Focused area treatment
2. Implementation Controls:
   • Vacuum truck deployment
   • Hydraulic control maintenance
   • Contaminated water removal
   • Treatment optimization
   • Distribution verification

Impressive Results

The treatment exceeded all objectives:

• Initial concentration: 7.544 mg/L
• Target level: 6.970 mg/L
• Final result: Non-detect
• Achievement: 100% reduction
• Exceeded compliance goals

Path to Closure

Current status and next steps:

• Quarterly monitoring program
• Continued verification
• Progress toward closure
• Regulatory compliance tracking
• Long-term effectiveness confirmation

Key Success Factors

Several elements contributed to perfect results:

1. Precise injection placement
2. Strategic BAM application
3. Effective hydraulic control
4. Focused treatment area
5. Comprehensive monitoring
