Site Description[1] 
The Cineplex site is located at 183-15 Horace Harding Expressway, Queens. The 1.6 acre site is approximately 100 feet east of the intersection of the Horace Harding Expressway and 183rd Avenue in the fresh Meadows section of Queens. The site is currently unused. Several buildings were on the site, but they have been demolished. Previously, the site had a movie theater, a dry cleaner and several small businesses. The site is in an area that has both commercial and residential buildings. The former dry cleaner has contaminated the groundwater at the site and across Booth Memorial Ave. Additional groundwater contamination at the site was caused by the gas station on an adjacent property. A remedial investigation is under way. An IRM soil removal is also under way. The intent of the IRM is to remove the heavily contaminated (tetrachloroethylene) soil in the vicinity of the former dry cleaner.

Site Environmental Assessment

The primary contaminants of concern are PCE and its breakdown products. Previous investigations have shown that the PCE plume extends beyond the northern boundary of the site. Soils in the area of the former dry cleaner had concentrations of PCE as high as 29,000 ppb. These soils were removed through an interim remedial measure. The site presents a significant threat due to the migration of the plume towards the residential area to the north of the site.

Site Health Assessment

The site is a former movie theater and dry cleaner that has been demolished and is proposed for redevelopment. Contamination is primarily tetrachloroethene and its breakdown products from the dry cleaner and some petroleum-related compounds from the gas station located adjacent to the site. On-site soil, soil vapor and groundwater contamination has been identified at the site. Contaminated groundwater and soil vapor has been identified off-site beneath a residential area. The site is fenced. Therefore, exposure to contaminated soils is not expected. Exposure to contaminated soils in the future is unlikely since buildings and pavement will cover the site. Exposure to contaminated groundwater is not likely since the area is supplied by public water. On-site vapor intrusion is a potential pathway for buildings constructed in the future. Off-site soil vapor intrusion has identified a couple of residential structures that warrant monitoring. Additional investigation regarding the extent of off-site inhalation exposure via vapor intrusion is necessary.
