Overview
At an operating manufacturing facility, free phase petroleum hydrocarbons were discovered underneath the facility. Soil concentrations of PHCs included:
- BTEX (maximum concentration of 5 μg/g )
- F1 & F2 (maximum concentration of 4,920 μg/g )
- F3 & F4 (maximum concentration of 44,000 μg/g )
Scope of Work
- Acquired all relevant permits to complete the remediation program
- Designed and optimized an in- program to maximize treatment efficiencies
- Implemented a program that minimized capital expenditures and infrastructure
The Vertex Approach
- Chemical oxidation and enhanced aerobic biodegradation
- Three applications
- Under floor slab and footing
- Injection of chemical oxidant
- 950 kg of RegenOx
- Injections completed using:
- Horizontal & vertical wells
- Direct placement
Outcome
- Over 7,000 L of oxidant solution delivered to impacted areas
- Operations not interrupted
- Remediation objectives met:
- BTEX
- F1 & F2
- F3 & F4
- Free phase treated in-situ
- Record of Site Condition Obtained
