brownfield VOCs CVOCs "vapor intrusion"

With revenues of over $48 billion in 2007, Pfizer ranks as the world's largest pharmaceutical company.  Established in 1849, Pfizer launched their chemicals business from a building at the intersection of Harrison Ave and Bartlett St, just a block from what would later become Pfizer Site B.

Site Description[1]
Site B is located in the eastern portion of what used to be Pfizer's sprawling Brooklyn headquarters complex.  The property is bordered on the north by a poultry market, vacant land, a three-story apartment building, and an auto body garage/yard; on the south by Gerry St; on the east by a portion of the auto body garage/yard and a storage lot; and on the west by Harrison Ave. All of the on site buildings were demolished in 1996 leaving a reinforced concrete slab across half of the eastern portion of the site. The western portion of the site is covered with gravel and is being used as a parking lot. Interim remedial measures removed all the hazardous and contaminated soils from the western portion of the property. The eastern half of the property, which is not owned by Pfizer, was sold to be developed as a Yeshiva School. This portion is being remediated. The groundwater plume is being remediated through a soil vapor extraction (SVE) system. The SVE system was installed in October 2006 and is currently in operation.

Site Environmental Assessment
On-Site contaminated soils have been excavated and disposed of off-site. The contaminated groundwater plume extends across the property boundary.

Site Health Assessment
Soil and groundwater are contaminated with volatile organic compounds and metals. Contaminated soil has been excavated and disposed of off-site. A fence around the site and clean fill minimize the potential for exposure to residual contaminated soil. The area is served by public water, therefore, exposure to contaminated groundwater is unlikely. On-site soil vapor is contaminated with benzene, toluene, xylene, and tetrachloroethene. A soil vapor extraction/air sparging system is operating on-site to reduce the contamination in groundwater and soil vapor. This system reduces the potential for exposures associated with soil vapor intrusion.
