Site Description Location Description: This site includes multiple parcels including property located at 275-297 Locust Avenue, 881 East 139th Street, 880-908 East 140th Street, 900-902 East 141st Street and 901-903 East 140th Street, Bronx, New York, Bronx County. This site is 1.83 acres in size. Site Features: The site is made up of three adjacent lots. Lot 46 comprises an entire block and includes an industrial warehouse. Lots 74 and 86 are two small fenced parking lots situated across E 140th Street from the Lot 46 warehouse. Current Use: The site is currently vacant. The intended use is industrial. Surrounding Uses: The surrounding parcels are currently used for industrial purposes. A dry cleaner and a heating fuel distribution center neighbor the site. Historical Source(s) of Contamination: Prior uses that appear to have led to site contamination include a manufactured gas plant, a gas holder, industrial storage, petroleum/diesel stations, and automotive service stations. Site Geology and Hydrogeology: Soil borings completed to date show the Site is immediately underlain by a fill layer comprising a mix of sand, silt, gravel, cobbles, and anthropogenic materials. Beneath this fill layer is a highly organic layer that most likely represents river or marsh deposits. Bedrock was not encountered during any of the soil borings, however, regional bedrock is known to consists of Paloeozoic Age rocks which may include either a metamorphic amphibolite shist, known as the Manhattan Formation, or the Proteriozoic Age Fordham Gneiss, a tightly banded quartzose rock. Groundwater is present beneath the Site, at approximately three (3) to five (5) feet bgs. Groundwater is assumed to flow in a southeasterly direction towards the East River and it appears that groundwater elevation and flow direction may be influenced by tidal conditions. Groundwater flow direction may also be influenced by building construction utilities and subsurface variations in geology. Investigations/Actions Performed to Date: As of this update, completed investigations include a Phase I and Phase II Site Assessment (2009). Current Actions: This site is the subject of a Brownfield Cleanup Program (BCP) Application, which is currently under review by the Department of Environmental Conservation.
Site Environmental Assessment Nature and Extent of Contamination: Based on the investigations conducted to date the primary contaminants of concern at the site known at this time include chlorinated solvents and BTEX (benzene, toluene, ethylbenzene, xylene) compounds. Soil - Concentrations of PCE found in on-site soils(5 ppm to 370 ppm) significantly exceed the soil cleanup objectives for the protection of groundwater (0.47 ppm) and the industrial SCO (300 ppm). The greatest PCE concentration in soil was found on the northwest corner of lot 46. Concentrations of Benzo(a)pyrene (.4 ppm - 7.3 ppm) exceed the industral SCO of 1.1 ppm. Groundwater - Concentrations of PCE found in on-site groundwater (5 ppb - 39,000 ppb) exceed the groundwater standard of 5 ppb. PCE breakdown products, TCE, cis-1,2 DCE, and vinyl chloride were found in exceedance of standards at maximum concentrations of 6,900 ppb, 40,000 ppb, and 16,000 ppb respectively. Detections of benzene, toluene, ethylbenzene, and xylenes also exceeded standards at maximum concentrations of 1,400 ppb, 400 ppb, 2,000 ppb, and 1,600 ppb respectively. Special Resources Impacted/Threatened: Studies are ongoing to determine if releases from the site have impacted/threatened any special resources.
Site Health Assessment Information submitted with the BCP application regarding the conditions at the site are currently under review and will be revised as additional information becomes available.
