OU1 - Site 4 LANDFILL WEST OF "D" GROUP
Site 4 is a 1-acre site located east of Macassar Road, which received approximately 10,200 tons of mixed domestic and industrial wastes from 1943 to 1960. Materials were placed in trenches, burned, and then covered with a thin layer of sandy soil. Pine trees were planted on much of the site in the early 1980s. Low levels of solvents and metals have been detected in shallow groundwater at the landfill boundaries. After significant investigation, no concentrated source area of solvents could be identified. HydroPunch samples collected during the 1995 Remedial Investigation field investigation did not detect any migration of the solvents into deeper aquifers. Polychlorinated biphenyls were found in one sediment sample at a very low concentration. The Record of Decision for remediation of this site was signed in August 1997. The selected remedy consisted of grading and capping the landfill, prohibiting use of groundwater in the adjacent area, and long-term periodic monitoring of groundwater conditions. Construction of the landfill cap was completed in July of 1998. The Navy conducts post remediation groundwater monitoring on an annual basis. The Third Five-Year Review was completed in March 2013. Because site-related COCs remain in groundwater at concentrations above NJDEP groundwater quality standards, continued monitoring and reporting are required.
OU1 - Site 5 Landfill West of Army Barricades
Site 5 is a landfill approximately 13-acres in size and received approximately 6,600 tons of mixed domestic and industrial wastes between 1968 and 1978. Wastes included paper, glass, plastics, construction debris, pesticide and herbicide containers, containers of paint, paint thinners, varnishes, shellacs, acids, alcohols, caustics, and small amounts of asbestos. Approximately 1 acre of the site was used as a skeet shooting range. The ROD for remediation of Site 5 was signed in August 1997. Capping, institutional controls, and long-term monitoring are the components of the selected remedy. Construction of the landfill cap was completed in July 1998. Lead-impacted soil from the shot fall area of the shooter's club skeet range was disposed off site. Site inspections are currently being conducted on an annual basis. Long term groundwater monitoring is conducted every two years. The Third Five-Year Review was completed in March 2013.
OU2 - Site 19 Paint Chip and Sludge Disposal Area
Paint chips and sludges from an ordnance maintenance area were disposed of, from the early 1940s until the early 1960s, in a topographic depression near Building S-34. Paint slurries and solvent residues were also discharged into an open drainage swale. The site is a 300-foot circular area; half is paved with asphalt and half is covered by gravel. The depression is 50 feet in diameter, with a depth ranging from five to 10 feet. The drainage swale runs from the depression to a small stream in the wetlands adjacent to the site. The asphalt paved portion of the site is currently used by the Navy for training of forklift operators. The ROD for remediation of Site 19 was signed by the Navy and EPA in August 1997. Excavation and off-site disposal of contaminated soils and sediments, institutional controls and long-term groundwater monitoring are the components of the selected remedy. In 1998, the Navy conducted several remedial measures, including the removal of vegetation and trees from the settling basin and ditch and excavation of contaminated sediments. Following the collection of confirmatory samples, the settling basin was backfilled to surrounding grade and paved with asphalt. The Third Five-Year Review was completed in March, 2013.
