The Woodridge, NJ Aerospace Manufacturing Facility was the subject of an ISRA remedial action. In support of site remediation, CODE was contracted to install a dual phase vapor extraction system in a nearly five acre tank farm field, which had been in operation since the 1940s.

The tanks ranged in size from 2,000 to 20,000 gallons and were located in tank farms in close proximity to the main manufacturing areas. In order to construct the dual phase vapor extraction system, CODE cleaned, demolished and removed a total of 45 USTs from the site. In excess of 10,000 tons of subsurface structures required demolition including building slabs, vaults, and concrete footings. Many of the tanks were encased in concrete and this had to be removed prior to demolition.

Site groundwater was contaminated with TPH from various grades of oils including waste oils and jet fuel.

CODE installed manholes at 30 well points and excavated and constructed the entire trench matrix system (in excess of 3,000 lf). CODE installed 2" electrical conduit and schedule 40 and 80 pvc piping ranging in size from 24" to 4". The system was piped to and connected with the facility’s existing wastewater treatment plant.

CODE installed and tested all system components, including all associated electrical work. Following the installation, the areas were restored with concrete and asphalt.

The project was performed during the final phase of the plant’s operation and the work had to be closely coordinated with the ongoing priorities of the scheduled shut downs.
