Overview
At an industrial site in New Jersey, historical leakage from a UST released petroleum hydrocarbons into the underlying groundwater and soil creating a health and ecology risk to overlying and down gradient receptors. Soil concentrations of PHCs included:
- BTEX (maximum concentration of 1,140 μg/g)
- F1 & F2 (maximum concentration of 4,200 μg/g)
- F3 & F4 (maximum concentration of 1,100 μg/g)
Scope of Work
Vertex staff:
- Acquired all relevant permits to complete the remediation program
- Designed and optimized an in-situ program to maximize treatment efficiencies
- Implemented a program that minimized capital expenditures and infrastructure
The Vertex Approach
- Chemical oxidation
- Overburden formation
- Multiple applications
- Under parking lot and roadway
- Injection of chemical oxidant
- Activated Persulphate
- Hydrogen peroxide activator (Klozur)
- Injections completed using:
- Vertical wells
Outcome
- Over 40,000 L of oxidant solution delivered to impacted areas
- Minimal disruption to operations
- Nearby structures not affected
- Persulphate solution effectively distributed thoroughout impacts areas
- Remediation objectives met for:
- BTEX
- F1 & F2
- F3 & F4
- Record of Site Condition Obtained
