Site Description[1]
Parcel 8 of the Queens West development is bounded by Center Boulevard on the east, 48th Avenue on the south, Peninsula Park on the west, and 47th Road on the north. The Site is vacant; all former structures were demolished in 2001. Surrounding parcels include Parcel 9 of the Queens West development to the east (Site #C241049), which received a COC for Restricted Residential Use December 2006; Stage II of the Queens West development to the north (Site # V00505), which is currently undergoing remediation; Peninsula Park and the East River to the west; and mixed uses to the south, including residential, commercial, a day care, a public school and Gantry Plaza State Park. The Site was originally part of the East River and was man-made by extensive filling, which raised the surface elevation and expanded the shoreline into the river (circa 1898). The Site historically housed industrial operations and was occupied by the Warren Chemical Co. until 1915, which produced roofing materials, tar paper and asphalt. Pumps, tanks, condensers, dryers, steam stills, and stacked drums associated with the production of these products are known to have been used on Site. Following Warren, the Site was used by the Liquid Carbonic Company, which produced liquefied carbon dioxide for soda fountains, from the 1930s until the 1950s. In 1970 the Site was occupied by a metal storage warehouse. Hallen Contractors occupied the Site from the 1970s until the Site was vacated in 2001. Parcel 9, adjacent to the east of the Site, has been occupied by varnish and paint manufacturers on the eastern portion of Parcel 9, and a variety of manufacturing uses on the western portion, including the Blau Gas Company, an asphalt company, the Harlem Chemical Co., a plumbing supply manufacturer, a refrigeration equipment manufacturer, a barrel manufacturer, and an auto repair shop. Investigations were conducted in 1985, 1989, 1998, 2000. Sampling was performed in 2006 as part of an off-site investigation for Parcel 9. Elevated levels of coal tar compounds were detected in soils and groundwater, exceeding Unrestricted Use Soil Cleanup Objectives. An Interim Remedial Measure (IRM) for removal of a large soil and construction and demolition debris pile was completed June 27th 2008. The Supplemental Remedial Investigation Work Plan (SRIWP) was approved on July 8th, 2008. Remedial investigations are currently ongoing at the site.

Site Environmental Assessment

The land of Parcel 8 is man-made and was created by filling areas along the East River in the late 19th century. The site was occupied by Warren Chemical Company, a producer of roofing materials, tar paper and asphalt. Equipment and stacked drums associated with the production of such chemicals are known to have been used on site. Adjacent properties (Queens West Parcel 9 to the east and OU-1 to the north) also have a known history of environmental contamination. Previous investigative programs were performed in 1985, 1989, 1998, and 2000. The most recent investigation was performed in 2006 as part of an off-site investigation of the neighboring Parcel 9 site, which included soil and groundwater samples on the Parcel 8 site. No free phase NAPL was found in any of these on-site monitoring wells, however, residual NAPL was detected in soil samples, primarily in the saturated zone. The principal contaminants affecting site soils are coal tar related compounds (including BTEX, and PAHs such as naphthalene, benzo(a)anthracene, benzo(b)fluoranthene, chrysene, and pyrene) which exceeded unrestricted soil cleanup objectives. Groundwater exceedences of NYS Class GA Ambient Water Quality Standards include BTEX and naphthalene. Remedial investigations including sampling of soil, groundwater, soil vapor, sediment, and ambient air are currently ongoing at the Site. Due to the severity of the contaminants found on this site and the exposure potential on and off site, this site poses a significant threat to the environment.

Site Health Assessment
Volatile organic chemicals and polycyclic aromatic hydrocarbons are likely present on-site. The actual composition of surface material is unknown and could present a potential exposure. However, a proposed interim remedial measure will contain contamination and minimize the potential for public exposures. The area is served with public water; thereby preventing exposures to contaminated groundwater. Additional information will be evaluated as it becomes available.
