Site Description[1] 
The Kliegman Brothers site is located in an urban area of Queens County in NYC and was formerly used as a distribution center for laundry and dry cleaning supplies and operated from 1950 through the 1990s. The property is approximately 37,000 square feet in area, of which approximately 26,000 square feet is occupied by a building and the remainder by a paved yard to the north of the building. The site is currently being used as a packaging and distribution facility for imported food products. The area surrounding this property is residential. Investigation work began on the site under the Voluntary Cleanup Program (VCP) by the current owner, but this VCP was terminated in October 2002 and the State assumed responsibility for remediating the site. NYSDEC completed a state-funded Remedial Investigation and Feasibility Study (RI/FS) in October 2005. An Interim Remedial Measure (IRM) involving construction of a Soil Vapor Extraction (SVE) treatment system was completed in 2004 and continues to operate. Between August 2004 and December 2007, the IRM SVE system is estimated to have removed over 40,000 pounds of PCE from the subsurface. NYSDEC presented a proposed cleanup plan to the public and, after all public comments were considered, a remedial action was selected for the on-site soil remedy (Operable Unit 1) and documented in a March 2006 Record of Decision (ROD). The selected remedy was to expand the existing SVE system to cover the entire on-site portion of contamination. Engineering design of the OU1 cleanup remedy was completed by NYSDEC in April 2007. Ground/Water Treatment and Technology (GWTT) of Denville, New Jersey, was awarded the contract and given formal notice to proceed with the project in October 2007. Construction of the remedy was completed in December 2007. As part of the cleanup remedy, NYSDEC added new components to the existing IRM remedial system, including six additional vapor extraction wells and another SVE treatment system. The existing IRM SVE system remains in place and continues to operate concurrently with the new treatment system. The remedial investigation/feasibility study for OU2, which includes groundwater and off-site soil vapor contamination, has been completed, a ROD was issued March 2008 calling for in-situ treatment via chemical oxidation and an extraction well to increase groundwater movement and treatment effectiveness. Exposure to contaminated soil is unlikely because it is located at depth beneath the on-site building and pavement. The soil vapor extraction system operating on-site to reduce the levels of tetrachloroethene in the soil vapor also prevents soil vapor intrusion into the on-site building. The extent of the soil vapor plume has been defined and mitigation systems have been installed where necessary in nearby homes to prevent vapor intrusion from occurring. Monitoring of sub-slab soil vapor and indoor air will continue as needed. The area is served by public water, therefore, exposure to site-related contaminants in drinking water is unlikely.

Site Environmental Assessment
Site contamination has impacted the groundwater resource in the overburden aquifer, however, groundwater near this site is not used as a source of drinking water. The surrounding land use is residential, and there are no environmental resources affected other then the groundwater.
