The Delaware Sand and Gravel site covers 27 acres and is located about two miles from the City of New Castle, Delaware. Formerly, a sand and gravel quarry, the site is now an inactive industrial waste landfill. Portions of the site are currently used as a salvage yard and a propane supply business. Landfilling operations started at the quarry in 1968. Industrial waste and construction debris, including thousands of drums of hazardous material, were landfilled in the quarry. The site was closed as a landfill in 1976, following an enforcement action by the State. It received Superfund National Priorities List status in 1982.
