Superfund Record of Decision (EPA Region 2): Naval Air Engineering Center,(Operable Unit 4), Lakehurst, NJ. (Third Remedial Action), September 1991

摘要

The 7,400-acre Naval Air Engineering Center (NAEC) site, which contains manysubsites, is a naval research design and testing facility near the Jackson and Manchester Townships, Ocean County, New Jersey. Subsequent investigations in 1990 discovered a gasoline leak in an underground pipe, which apparently was the source of ground water contamination. Onsite actions have included repairing the leak and excavating and disposing of 65 cubic yards of visually-contaminated soil. The ROD provides an interim remedy for ground water contamination. The primary contaminants of concern affecting the ground water are VOCs including benzene, toluene, and xylenes; and other organics including PAHs. The selected remedial action for the interim remedy includes onsite pumping and pretreating ground water using precipitation and filtration to remove metals, solids and residual amounts of free product, and air stripping to remove VOCs; filtering the effluent from the treatment process water using a granular activated carbon polishing filter, and discharging the treated water onsite.
