Hazardous Waste Cleanup: Dupont E.I. De Nemours and Company Incorporated in New Cumberland, Pennsylvania

Cleanup Status

The E.I. du Pont de Nemours and Company (DuPont) facility received a Final Decision for No Further Action (NFA) from the U.S. Environmental Protection Agency on January 23, 2009. The decision to issue an NFA at the Facility was based on a review of EPA and Pennsylvania Department of Environmental Protection (PADEP) files regarding the environmental history of the Facility and an Environmental Priorities Initiative Preliminary Assessment (PA) Report submitted on September 11, 1989. EPA concluded that there are no current or unaddressed releases of hazardous constituents from the Facility and no further corrective action or controls are necessary at this time.

Environmental Indicators (EIs) were completed on December 2, 2008. The two EIs are "Current Human Exposures Under Control" and "Migration of Contaminated Groundwater Under Control." The EIs completed reflect the decision of No Further Action and have status codes of "Yes, Under Control" for both.

The Facility was located at 211 Limekiln Road in New Cumberland, Pennsylvania. DuPont leased an approximately 60,000 square foot building from the property owner from 1973 to 1984. Beginning in 1980, hazardous wastes were stored on a 900 square foot concrete pad adjacent to the northwestern side of the building. This activity ceased in 1984, when DuPont vacated the property.

The Facility is located one quarter mile south of the New Cumberland corporate boundary in York County, Pennsylvania. At the time of the PA, the Facility was bordered by undeveloped land. More recent research into aerial photos in Google Earth and USAPhotoMaps shows the Facility to be currently bordered by The Pennsylvania Turnpike on the south, commercial/light industrial properties on the east and west, a wastewater treatment plant towards the northwest and some residential properties farther north across Yellow Breeches Creek.

In April 1983, DuPont indicated that it was closing the Facility and ending the lease agreement. A closure plan for the concrete pad, also called the drum storage area, was submitted on September 4, 1984. As part of the closure, the concrete pad was scrubbed and the resulting material sent for proper disposal. Although no releases were reported and there was no evidence of spills or releases during the PA site visit, soil samples were obtained from areas surrounding the concrete pad. Results showed only low levels of 1,1,1-trichloroethane at 9 ppb and 15 ppb, well below EPA's current screening level for residential soil of 22,000 ppm.
