Regulatory Agency: New Jersey Department of Environmental Protection
Contaminants: Petroleum Hydrocarbons and Chlorinated Solvents Remediation: Pump & Treat and Soil-Vacuum Extraction
Treatment: Suspended Solids Separation; Dissolved Metals Sequestering; Oil/Water Separation; Air Stripping; and Thermal Oxidation
Scope: Investigate, Investigate, Design, Build and OperateProject Summary
- ESI committed to investigate, design, build, and operate a remediation program to meet regulatory requirements for closure.
- Two separate systems were identified as the most cost-effective method to obtain closure, because an evaluation showed that adding a second system in the first few years greatly reduced the time to closure, and the costs.
- After installation, the tray stripper was found to be operating at 99.9% removal efficiency, eliminating the need for further treatment prior to discharge.
This 5-acre, active printing supply facility was underlain by separate and dissolved phase contaminants. Product thickness ranged from a trace to approximately one-foot, and consisted of a mixture of light end volatile petroleum hydrocarbons and chlorinated solvents.
