Site Description[1] 
Location: The site is located in an urban area on the west side of Coney Island Ave., approx. 150 ft south of Ocean View Ave. Site Features: The site is a vacant lot with an out-of-service 500 gallon underground storage tank in the NW corner of the property. The lot is enclosed with a plywood construction fence. Current Zoning/Uses: The site is currently zoned for residential use. Surrounding parcels are single family homes and apartment buildings. Historical Uses: The property was formerly improved with a 1-story commercial building that was utilized as a dry cleaner by Brighton Cleaners for at least 30 years. The building and a metal storage shed were demolished in 2009. Site Geology and Hydrogeology: The property is located within the "Pavement & Buildings-Hooksan-Verrazano Complex" as identified by the NYC Soil and Water Conservation District, which is characterized by 0 to 8 percent slopes, nearly level to gently sloping urbanized area of sandy sediments that have been substantially cut and filled. Groundwater is encountered at approx. 8 ft below grade. Groundwater flow is to the south in the area of the subject site.

Site Environmental Assessment
Nature and Extent of Contamination: Based on the investigations conducted to date, the primary contaminants of concern at the site are Tetrchloroethylene (PCE) and its decomposition products. Both soil and groundwater at the site are impacted by PCE Soil: PCE and it decomposition products were detected in soil at concentrations exceeding the Part 375 Unrestricted Use soil cleanup Objective (UUSCOs), with a maximum PCE concentration of 3200 ppm and a maximum Trichloroethene (TCE) concentration of 71 ppm. Additional soil investigation is needed to delineate the extent of the soil contamination at the site. Groundwater: PCE was detected in groundwater at a maximum concentration of 42,000 ppb; TCE with maximum concentration of 6700 ppb; and cis-1,2-dichloroethene (DCE) with a maximum concentration of 8200 ppb. The impact to the groundwater appears to be throughout the entire site, and further investigation is needed to define the extent of the groundwater contamination. Soil Vapor: No soil vapor data has been collected thus far.
