- In October 1992, the Kent County Landfill site was removed from the U.S. Environmental Protection Agency’s National Priorities List, based on a May 1992 decision from the U.S. Court of Appeals for the District of Columbia Circuit.
- Therefore, the parties potentially responsible for site contamination are no longer obligated to continue cleanup work under a 1991 EPA order.
- The site is currently being addressed under the State of Delaware’s Hazardous Substance Control Act.
- The approximately 100-acre Kent County (Houston) Landfill site was operated as a municipal landfill by the County from 1969 to 1980. Residential trash, sludge from poultry processing plants, oil sludge, hospital wastes, waste polymers, and solvents were accepted at the facility.
- The landfill holds an estimated two million cubic yards of waste and fill materials. The wastes were deposited in unlined trenches.
- In 1980, the County covered the landfill with three to five feet of sandy soil and planted grass and other vegetation.
- In 1980 and 1984, EPA found contaminants in a monitoring well screened in the water table aquifer underlying the site. EPA also found contaminated leachate seeping from the landfill. Approximately 684 people use private wells within three miles of the site. About 1,200 acres of cropland within three miles of the site are irrigated by well water, and surface water near the site is used for recreational purposes.
