Stage of Clean-up: Construction Completed
Conditions at listing (October 1981): The Army Creek Landfill covers 47 acres in New Castle County, Delaware. It is adjacent to the Delaware Sand & Gravel Landfill and was owned and operated by the county as a municipal and hazardous waste disposal facility until it reached capacity in 1970. The site holds 1.9 million cubic yards of refuse. Since 1972, the county has spent $3 million to control the migration of contaminants, including LEAD, CHROMIUM, ARSENIC, and a variety of organic compounds, to an aquifer that supplies water to over 100,000 people. This site was first listed under the name "Delaware Sand & Gravel -Llangollen Army Creek Landfills." Status (July 1983): The State is drafting a National Pollutant Discharge Elimination System permit for the discharge of the ground water to Army Creek. EPA recently completed a Remedial Action Master Plan outlining the investigations needed to determine the full extent of cleanup required at the site. It will guide further actions at the site.
