| Abstract |
The 2-acre Sealand Limited site, a former coal tar treatment and recycling facility, is located in Mt. Pleasant, New Castle County, Delaware. Ground water underlying the site is used as a source of drinking water. Sealand allegedly conducted treatment, processing, and recycling of coal to tar and off- specification creosote wastes onsite until abandoning the site in 1983. A 1983 State investigation discovered 21 steel tanks or hoppers; a 10,000-gallon wooden storage tank and 300 55-gallon steel drums, which were leaking liquids onsite; a boiler house; and various mixing chambers and pressure vessels on the abandoned site. Additional studies by EPA and the State identified organics including PAHs, creosols, and solvents in the onsite soil, drums, and tanks. Subsequently in 1983, EPA conducted an emergency removal action. The Record of Decision (ROD) addresses onsite soil as the first and final operable unit (OU1). All hazardous materials contained in abandoned onsite tanks and drums were disposed of offsite during the EPA removal action, and any remaining soil contaminants pose low risks for humans at the site. Based on this rationale, there are no primary contaminants of concern affecting the site. The selected remedial action for this site is no action. |
