Site Description[1]
The Far Rockaway Former MGP Site is located in a mixed commercial and residential area of the Borough of Queens, NY. The site is located on the north side of Brunswick Avenue between Beach 12th Street and Milton Avenue. The site is also known as 1200 - 1224 Brunswick Avenue. The site is not currently owned by KeySpan. The site is approximately one acre and contains three two-story buildings, paved parking lots and landscaped areas. Currently the site is used for office space and warehousing. To the north of the site is the Long Island Railroad. Beyond the railroads are commercial buildings. To the east and south are residiential houses. To the west are commercial buildings. The site was operated as a "gas works" between 1900 and 1909. Following the operation of the MGP the site was utilized as office space. Several alterations to the structures on site have been made since 1911. Completed investigations include a Preliminary Site Investigation dated in April 2003. The results of the PSA indicate the constituents of MGP tar are found in the soil, groundwater, and soil vapor. These include BTEX, and PAHs. Cyanide was also found in the soil. Contraventions of groundwater and soil SCGs are documented. The Remedial Investigation began in November 2007, and is ongoing. Soil vapor results do not indicate the need for mitigation or monitoring. Additional downgradient sampling is necessary to fully delineate the groundwater plume. A plan for this work was approved in June 2008, and the field investigation began in November 2008.

Site Environmental Assessment
Investigations indicate that unsaturated and saturated soils, and groundwater contain contaminants that exceed State standards. The results of the PSA indicate the contaminants associated with MGP tar are found in the soil, groundwater, and soil vapor. These include BTEX, and PAHs. Cyanide was also found in the soil. Contraventions of groundwater and soil standards, criteria, and guidance concentration values are documented.

Site Health Assessment
Contact with site-related contaminants in soil is unlikely because they are beneath buildings and pavement. The area is served by public water, therefore, exposure to site-related contaminants in drinking water is not expected.
