Site Description[1]
The Levco Metals Finishers property is located in an industrial area of Long Island City. The entire site is occupied by a one story building which covers approximately 21,900 sq.ft. Levco was a metal finishing facility which conducted metal stripping, etching, and plating processes for over 30 years. Company operations ceased with the death of the owner, in November 1990. The site was first investigated in 1987. Elevated levels of 1,1,2-trichloroethylene (TCE) were found in the groundwater, along with various breakdown products. The round of sampling, conducted in 1992, indicated higher amounts of TCE in the groundwater and soil around a floor sump located in the eastern portion of the building. An Interim Remedial Measure (IRM) consisting of the removal of 13.5 cubic yards of contaminated soil from within and beneath the sump took place in October 1994. Following the IRM, the supplemental site investigation was performed in November 1994. It showed that soil on site was remediated to the levels of the soil cleanup objectives, except for insignificant exceedances in a former sump area. The primary source of groundwater contamination, being the soil beneath the sump, has been removed. In April 1995, additional groundwater monitoring was conducted. It confirmed the expected reduction of VOC concentrations in groundwater in the sump area and in downgradient wells. In March 1996, the Record of Decision (ROD) was executed, which recommended delisting of the site from the Registry. The site has been delisted from the Registry in May 1996. The ROD also recommended additional groundwater monitoring on a semi-annual basis. From 1996 to 2001, several rounds of groundwater monitoring have been conducted and showed that the contaminant levels in the groundwater beneath the site have not declined to acceptable levels. To address remaining contamination in the groundwater, the Site owner entered into the Voluntary Cleanup Agreement with NYSDEC in 2002 and designed Remedial Action Work Plan to remove remaining contaminants. This additional remedy has commenced in 2005 and is ongoing.

Site Environmental Assessment
IRMs achieved the main remedial goals of the removal of hazardous waste in the former sump area and the cleanup of on-site soil to levels protective of the public health and the environment. Additional remedial action commenced in 2005 under the Voluntary Cleanup Agreement which is intended to address residual contaminants in the groundwater. Site Contamination Soil: Prior to IRM: elevated concentrations of volatile organic compounds (e.g., 2 ppm trichloroethane; 3.5 ppm trichloroethene) and metals (e.g. 21.2 ppm cadmium; 12 ppm chromium) were detected in the soil beneath the sump area. Contaminated soil from this area was excavated and disposed off site in October 1994. Groundwater and soil gas: On-Site groundwater is contaminated as a result of disposal activities. Predominant contaminants above Class GA groundwater standards are trichloroethene, 1,1,1-trichloroethane, and cis-1,2-dichloroethene.

Site Health Assessment
Soil and groundwater are contaminated with volatile organic compounds (VOCs). Exposure to contaminated groundwater is not expected since the area is served by public water. Contaminated soil is subsurface, therefore exposure is unlikely. A soil vapor extraction system is in place on-site to remediate VOCs in soil and soil vapor. Therefore, inhalation exposure via soil vapor exposure has been minimized. Additional data is needed to evaluate the potential for off-site exposure due to soil vapor intrusion.
