Outlet City, Inc.
Site Description[1]
This site is approximately .5 acres in size and is a portion of the Outlet City VCP site(#V00081) located at 28-10 Jackson Avenue, Long Island City. Intended use for this site is to build a multi-tenant high-rise residential apartment building with ground floor commercial space and a basement. Known contaminants at this site are petroleum, chlorinated solvents, SVOCs, metals, pesticides and creosote which are impacting the soil, groundwater and soil gas. The Remedial Work Plan was publicly noticed in June/July 2007 and was approved by the state on August 16, 2007.

Site Environmental Assessment
The release of approximately 5000 gallons of creosote caused extensive soil and groundwater contamination that includes the presence of LNAPL and residual DNAPL. This site is considered a significant threat to the environment. Contaminants in soil which exceed soil cleanup objectives primarily include: Naphthalene, 2-Methylnaphthalene, Acenaphtene, Dibenzofuran, Flourene, Benzene, Ethylbenzene, and total Xylenes. Contaminants in groundwater which exceed groundwater standards primarily include: 2-methylphenol, phenol, Napthalene, 2-methylnaphthalene, benzene, Toluene, Ethylbenzene, and total xylenes.

Site Health Assessment
The remedial investigation documented that subsurface soils and groundwater are contaminated with volatile organic compounds, semi volatile organic compounds, and chlorinated solvents. Exposures via drinking water are not expected because this mixed industrial/residential neighborhood is served by public water. The new building proposed for the site will include a vapor barrier and sub-slab depressurization system to prevent exposures via vapor intrusion. Additionally, the site will be capped with asphalt and managed through the site management plan which minimizes the potential for direct contact with residual soil contamination.
