Site Description[1]
The site is located at 230 Kent Avenue, Brooklyn, NY 11211 (Block 2362, Lot 1). It is bordered by Kent Avenue to the east, by River Street to the west, by North First Street to the south, and by the Former North First Street Oil Storage Terminal (a Con Ed property) to the north. On the site is an one story building with a partial basement. The building is used for paint and lacquer maufacturing. The current zoning is M3-1, heavy manufacturing. The Fyn Paint property is 500ft away from the East River. In the neighborhood, there are warehouses, other manufacturing facilities, and residential buildings. The soil and groundwater at the site are contaminated with elevated concentrations of VOCs. The site is curently in the remedial investigation phase. An Interim Remedial Measure (IRM) consisting of a groundwater pump and treatment system began operating inside the Fyn Paint Facility in 2007. A limited soil vapor intrusion survey around the property was performed in 2005. In Spring 2008 the IRM Report and the draft Remedial Action Work Plan (RAWP) were submitted, and are currently under review by NYSDEC and NYSDOH.

Site Environmental Assessment
The soil and the groundwater at the site are contaminated with Volatile Organic Compaunds (VOCs) from 14 closed-in-place underground storage tanks (USTs), and from spills which occurred during the manufacture of paint and lacquer products. The main VOCs in the groundwater are acetone, ethylbenzene, toluene, mixed xylenes, and 2-butanone. Groundwater flows towards the west (to the East River), and the groundwater plume has migrated under the adjacent Con Edison property. The depth of the groundwater is between 7 and 15 feet below grade. Monitoring conducted in 2006 revealed non-aqueous phase liquid (NAPL) and high concentrations of disolved-phase contamination in three monitoring wells on the site. Studies are ongoing to determine if releases from the site have impacted other properties located around the Fyn Paint Facility. The site has been determined to pose a significant environmental threat due to the groundwater contamination. In March 2007, an Interim Remedial Measure (IRM) consisting of a grounwater Pump and Treatment System with an activated carbon filtration stage was installed and is operating at full capacity. A NYCDEP permit has been obtained to discharge the treated groundwater to the municipal sewer system. A soil vapor intrusion investigation around the facility was performed. Groundwater monitoring and treatment at the site continues. The IRM Report and the draft Remedial Action Work Plan (RAWP) are under review.

Site Health Assessment
Public water is provided to the area, thereby preventing exposures to groundwater. The site and surrounding area are covered with buildings or pavement, which limits or eliminates the potential for direct contact. Elevated concentrations of vapors have been found off-site and may require additional actions to prevent exposures.
