Site Description[1]
This site is a 9 acre parcel.  Roughly one quarter of the site is paved with a small three story building in the northwest corner. The remaining portion is vacant, unpaved, and covered with scrub brush. It is only occasionally used for storage by the utility. The surrounding parcels are commercial and industrial. The nearest residential property is 200 yards to the south on the far side of the railroad. The site's historic use as a manufactured gas plant has led to coal tar contamination escaping from the gas holders, tar separator, and various independent disposal areas in the north and west portions of the site, including the bulkhead area north of Beach Channel Drive. A Record of Decision was issued for the site in October, 2004. The remedy includes a large-volume soil removal and two barrier walls to prevent further off site migration of coal tar. Remedial construction began on the site in October of 2008.

Site Environmental Assessment
The primary contaminants of concern known at this time are benzene, toluene, ethylbenzene, xylene (BTEX) and polycyclic aromatic hydrocarbons (PAHs). Investigations indicate a plume of dense non-aqueous phase liquid (DNAPL) proceeds vertically underneath the site roughly 110 feet and to the north of the site. This layer of DNAPL has created a groundwater plume that extends to the north and east just beyond the site and contamination in the soils under the site. Exceedances of standards, criteria, and guidance include BTEX and PAHs in groundwater and subsurface soil. Jamaica Bay is just to the north of the site. It is not currently impacted by the site, but may be in the future. The site represents a significant environmental threat because of ongoing releases from source areas of contaminants into the groundwater and its potential to release contaminants into Jamaica Bay.

Site Health Assessment
Groundwater is contaminated with benzene, cyanide, and polyaromatic hydrocarbons above standards for public drinking water supplies. There are no drinking water supply wells in the vicinity of the site, so community exposure to contaminated groundwater is not expected. Exposures to contaminated soil is unlikely unless subsurface excavations were to occur. Access to the site is restricted by fencing, therefore minimizing the potential for trespassers and the surrounding community to come in contact with contaminated soils.
