- To address the potential risks posed by elevated levels of chromium hexavalent, nickel, and tetrachloroethylene (PCE) in white resinous material in the soil of the Barren, Capped Landfill, and adjacent low-lying areas, engineered caps were constructed as interim measures in 2007.
- Concentrations of PCE and trichloroethylene (TCE) exceeding Maximum Contaminant Levels (MCLs) were detected in the groundwater beneath the eastern side of the Carbon Disulfide (CS2) manufacturing plant. The Corrective Measures Study (CMS) summaries the remediation alternatives proposed for remediating the contaminants in the groundwater and soil at the Akzo site. In February 2012 (revised September and November 2012), Akzo submitted an in-situ chemical oxidation pilot study work plan for assessing operating parameters for the effectiveness in treating the on-site PCE plume. The CMS and in-situ chemical oxidation work plan are currently under review by EPA. EPA anticipates issuing the proposed remedy decision document for this site in 2013, upon completion of the pilot study in the Spring of 2013 and final approval of the CMS.
The Akzo Nobel Chemicals, Inc. (Akzo) site is located in Delaware City, Delaware, 2.5 miles northwest of Delaware City in New Castle County Delaware. The property is bordered on the west by Route 14, on the north by the Conrail Railroad tracks, on the east by Schoolhouse Road, and on the south by Formosa Plastics, American Mirrex and Route 72 Wrangle Hill Road. The Akzo site consists of a decommissioned Carbon Disulfide manufacturing plant (including closed-loop process units, wastewater treatment system, storage and loading areas and underground storage tanks for gasoline and an unknown substance, two land disposal areas; Barren Area and Capped Landfill, and two small wetland areas), situated on a 52 acre area; a 123 acre Agricultural Parcel; and a 16 acre undeveloped parcel. The plant generated carbon disulfide and sodium hydrosulfide. Sodium hydrosulfide and waste oil were the only documented hazardous waste constituents stored in the drum storage area. Off-specification sulfur and ceramic brick debris are the known materials disposed of in the Barren Area and the Capped Landfill under Akzo’s ownership.
- The plant was constructed and began operation in 1960 under the original ownership of the Stauffer Chemical Company (Stauffer). Akzo acquired the site from Stauffer on or about December 21, 1987 and continued to operate it until 1992, when the facility was dismantled and closed under the supervision of the Department of Natural Resources and Environmental Control (DNREC).
- The contaminants that are present are elevated levels of chromium hexavalent, nickel, and tetrachloroethylene (PCE) in white resinous material in the soil of the Barren, Capped Landfill, and adjacent low-lying areas. Concentrations of PCE and trichloroethylene (TCE) exceeding Maximum Contaminant Levels (MCLs) were detected in the groundwater beneath the eastern side of the Carbon Disulfide (CS2) manufacturing plant.
