| Site Name | Naval Air Warfare Site | |
| Site Location | West Trenton, NJ | |
| Site Type | Naval Air Station | |
| Cleanup Program | Environmental Security Technology Certification Program | |
| Entity Responsible for Cleanup | Navy | |
| Project Name | Naval Air Warfare Site | |
| Project Technology | Conductive Heating (In Situ Thermal Treatment) | |
| Scale | Field Demonstration/Pilot | |
| Vendor | Not Specified | |
| Project Status | Complete | |
| Contaminants of Concern | cis-1,2-Dichloroethene Vinyl chloride Trichloroethene |
|
| Media Type | Groundwater Dense Non-aqueous Phase Liquids (DNAPLs) |
|
| Extent/size of area of contamination | The treatment area 400 square feet and included a volume of 740 cubic yards. | |
| Description of geology/hydrogeology | Mudstone bedrock in the area exists at 5 feet below ground surface. | |
| Cleanup goals or remedial objectives | The objectives of the thermal conductive heating pilot scale treatment effort were to reduce the contaminant lifespan in the fractured bedrock and reduce aqueous-phase contaminant flux and concentrations in the treatment area. | |
| Performance data available? | Yes | |
| Summary and description of performance data | After a 14-week pilot study, approximately 530 pounds of chlorinated VOCs were removed from the bedrock by vapor extraction and an additional 30 pounds of VOCs were removed from the water and condensed steam. Results showed that VOC concentrations in from the treatment area were reduced from 277 milligram/kilogram (mg/kg) prior to heating to below 5 mg/kg after heating. | |
| Comments | The Thermal Conductive Heating (TCH) pilot study operated continuously for 98 days, injecting 493,000 kilowatt-hour (kWh) of electricity into the treatment zone. The system involved 15 heater borings each with a vapor extraction screen to a depth of 55 feet below ground surface. Electricity was applied to reach a target temperature of 100 degrees Celsius. Air, stream, and fluids were extracted and contaminated water, and CVOC vapors went through an off-gas vapor and liquid treatment system. | |
