The Former W.L.K. Corp. Site (58-30 57th St.) is located near the intersection of Grand Avenue and 57th Street in Queens County. The site is identified on the Queens Business Borough Tax Map as Block 2610, Lots 412 and 440 and is approximately 2.01 acres in size. The site is bordered on the north by MTA/LIRR rail lines, on the south by Grand Avenue, on the east by 57th Street, and on the west by a property owned by Start 56-19 Grand Holding LLC. The site is mostly paved, with a small area overgrown with vegetation (former railroad spur) present adjacent to the western portion of the building. The northern portion of the site has historically been used by a radiator distribution facility (1930's-1940's), a steel pipe distributor (1950's- early 1970's), corrugated box company (early 1980's), a beer distributing company (mid/late 1980's), and a recycling facility (early 1990's - early 2000's). The southern portion of the site is currently occupied by offices and has been used for several businesses. A lubricating oils company occupied this portion of the site at least from 1936 into the 1970's. Over the years other occupants included an oil company sales office, a milk products company, and an engineering firm. Also, a filling station was located on the site at the corner of Grand Avenue and 57th Street from early 1930's to early 1970's. The site is currently used as a lumber yard with some offices. The surrounding parcels are currently used for a combination of commercial, light industrial, and transportation. The closest residential area is directly across 57th Street. The regional groundwater flow direction is generally to the southwest. Previous investigations in the area, by a third party, revealed high concentrations of chlorinated solvents (specifically TCE, 1,1,1-TCA, and 1,2-DCE) in the groundwater at the northwestern portion of the site. Based upon groundwater samples results, the groundwater contamination is decreasing southward beneath the adjacent property. The groundwater contamination detected at the site seems to indicate a source area around the loading dock located at the northern end of the site main building and/or an alley (former railroad spur) between the western property fence line and the building. A site characterization was completed and it was determined that the need exists for a full remedial investigation.
Site Environmental Assessment
The primary contaminants of concern detected in the Spring/Summer 2007 included Tetrachloroethylene (PCE) and 1,1,1-Trichloroethane (TCA) and their respective breakdown products. Exceedances of standards, criteria, and guidance in the on-site soils include TCE (max. 31 ppm), 1,1,1-TCA (1.1 ppm), PCE (max. 2.6 ppm), and total 1,2-DCE (max. 46.2 ppm). Exceedances of standards, criteria, and guidance in the groundwater include 1,1,1-TCA (max. 16 ppb), TCE (max. 710 ppb), PCE (max. 47 ppb), and total 1,2-DCE (max. 548 ppb). Samples taken off-site, adjacent to the former railroad spur area, revealed exceedances in the groundwater of 1,1,1-TCA (max. 71,000 ppb), TCE (360,000 ppb) and 1,2-DCE (max. 42,000 ppb). Based on the results of the site characterization investigation, a source of contamination has been confirmed to exist along the former railroad spur at the site. While a continuing source appears to be located near the former railroad spur, an historic source may have been located near the former dry wells or underneath the building. The site presents a significant threat to the environment due to the elevated soil and groundwater concentrations that are most likely caused by previous operations at the site. It is recommended to conduct a remedial investigation/feasibility study to fully define the nature and extent of the contamination and identify the most appropriate remedial action.
Site Health Assessment
Further investigation is needed to assess the nature and extent of site-related contamination and the potential for exposure to site contaminants. The site currently has several buildings and a paved parking lot, therefore, contact with subsurface contamination is unlikely. Exposure to site-related contaminants in drinking water is not expected because the area is served by public water. NYSDOH and NYSDEC will evaluate the need for additional investigations to determine the potential for soil vapor intrusion to occur.
