Site Description[1]
The 9.2 acres Harbor Estates property is located within the boundaries of the former "Ralph Avenue Truck Fill" in Brooklyn, and is bordered by Avenue M, E. 72nd Street, Avenue N and E69th Street. The site surrounds, but excludes, existing Peri Lane townhome development. A substantial part of the site cleanup under the DEC-approved work plan has been completed. The site is currently undergoing re-development which includes construction of town houses. Some of the new houses located in the areas of the site where cleanup had been completed have been occupied. The area surrounding the site is residential and includes a public school. There were several "hot spots" of hazardous waste and the groundwater was found to contain low levels of lead, barium, and copper. The remedial tasks of removing "hot spots" of contaminated soil and removing 2 feet of soil have been completed. Two feet of clean top soil are being placed on the site as new houses are being built.

Site Environmental Assessment
The property was historically used for the disposal of construction and demolition debris (C&D) and is commonly referred to as a C&D landfill. The existing on-site subsurface soil/fill earth materials were found to be contaminated with lead and polychlorinated biphenyls (PCBs) that were detected at elevated concentration levels above State-recommended soil cleanup objectives. There is also area-wide presence of semivolatile organic compounds at levels above State-recommended soil cleanup objectives. Groundwater on the site has exceedances of the groundwater drinking standards but does not pose threat to surface water in the Paerdegat Basin. According to DEC a groundwater remedy would not provide significant environmental benefit.

Site Health Assessment
Public water is provided to the area thereby preventing exposures to groundwater. The on-going redevelopment of the site calls for the placement of two feet of clean soil over any residual contaminated soil. Deed restrictions on the site prohibit digging into soil deeper than two feet. These measures will continue to prevent direct contact exposures .
