Site Summary:
Federal Register Notice:  September 08, 1983

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.
