EPA added the Syncon Resins site in South Kearny, New Jersey to the Superfund National Priorities List on September 1, 1983 because hazardous chemicals were found in the soil and ground water. The 15-acre superfund site located in Hudson County contained a facility that manufactured paints, varnishes, and resins. The site contained two unlined lagoons, numerous large bulk storage tanks and underground storage tanks, and over 12 buildings. Prior to their removal, the site also contained approximately 12,800 55-gallon drums. Many of the 55-gallon drums have rusted and spilled contents onto the soil. During the production process, wastewater containing solvents was pumped to an unlined lagoon, left to evaporate or drain into the soil.
Investigations of the site found extensive contamination of the ground water, soil, buildings, vessels and tanks. The ground water is contaminated with heavy metals such as lead and nickel, as well as volatile organic compounds (VOCs), which are potentially harmful contaminants that can easily evaporate into the air. Soil and sediments are contaminated with heavy metals, VOCs, and PCBs.
As an immediate action, the state removed all of the exposed 55-gallon drums from the site between 1982 and 1984. In 1990, the site was fenced off to provide additional security during the cleanup.
EPA decided on a long-term cleanup plan. The plan includes: decontaminating on-site buildings and tanks; excavating lagoon liquids, sediment and contaminated soils; installing a cover over the site that will allow natural flushing of soils and groundwater; collecting and treating contaminated water; and evaluating the possibility of enhancing the effectiveness of the flushing and treatment of contaminated soils. By removing all the 55-gallon drums and securing the site, the threat of exposure to hazardous materials has been greatly reduced. The ground water treatment system is currently operating. Current human exposures at this site are under control.
