Site Description[1] 
Location: The Brooklyn Gas Light Works Manufactured Gas Plant (MGP) is located at 1 Hudson Avenue in Brooklyn, New York in Kings County. Site Features: An active generating station (Hudson Ave.), owned by Consolidated Edison, currently operates at the site. The site is covered by buildings, some asphalt parking areas and walkways. Current Zoning/Use: The site is currently an active generating station and is zoned for light manufacturing and commercial uses. The nearest residential area is 0.3 miles to the south. Historical Use(s): The MGP plant operated from 1849 until approximately 1900. The property was sold to Brooklyn Edison Company between 1922 and 1928. The MGP buildings and associated above-ground structures were subsequently removed and the generating station was built. Consolidated Edison purchased the property and generating station in approximately 1950. Operable Units: The site is currently being managed as a single operable unit. Site Geology and Hydrogeology: The general geology in the area is artificial fill and alluvial deposits ranging between 15-20 feet thick. The next layer consists of glacial deposits (clay, sand, gravel and boulders); then a layer of Gardiner's Clay; coarse sand and gravel; a clay and silty clay layer; a sand layer interbedded with gravel clay and silt; and finally a bedrock consisting of gneiss, schist and pegmatite. Overall groundwater ranges between 5 and 22 feet below ground surface (bgs), and generally flows to the north towards the East River. The site groundwater is tidally influenced. A Site Characterization is planned to start in the summer of 2011.

Site Environmental Assessment
Prior to Remediation: The site characterization is tentatively scheduled for the summer of 2012.

Site Health Assessment
