Site Description The Brooklyn Navy Yard Voluntary Cleanup Program site consists of 264 acres of the 353 acre Brooklyn Navy Yard Industrial Park. The site is generally bounded by the East River on the north, Flushing Avenue to the south, Kent Avenue to the east and Navy Street to the west. The Navy Yard itself is an idustrial/commercial area, while the property surrounding the Navy yard is mixed commercial and residential use. The main site features include large dry docks used for ship repair, several older buildings, roadways and a newly-constructed movie studio. The site is currently used as an industrial park, including manufacturing, warehousing and the making of films. The surrounding area is commercial and residential. The site was used as a ship building and repair facility from the 1800's to the mid-1900's. These activities included metal fabrication, painting and sand blasting, as well as various support activities including the maintenance of their electrical system. These functions may have resulted in the release of metals, solvents and PCBs. The site has had two areas completey studied and remedies have been selected. The remaining property has undergone a comprehensive study, and a final decision on remediation is expected in mid-2008.
Site Environmental Assessment Former use of the site as a ship building and maintenance facility may have resulted in the release of metals, solvents, petroleum and PCBs to the ground surface. The nearby Navy Yard Basin, Walabout Bay and the East River could potentially receive contamination via overland flow of contaminated soils and/or groundwater. Studies performed to date have not indicated that the Voluntary portion of the Brooklyn Navy Yard site is likely to contribute significant contamination to these receptors, however, studies are on-going.
Site Health Assessment Site soil and groundwater have been contaminated with volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs) and heavy metals. Exposure to site-related contaminants in soil is unlikely since removal and disposal of contaminated soil has been performed and buildings and pavement also cover the majority of the site. The remaining soil is inaccessible and lies at depth. Exposure to site-related contaminants in drinking water is unlikely since the area is served by public water supply. Soil vapor intrusion does not appear to be a potential exposure pathway at this time.
