NPL Site Narrative for Colbert Landfill

Spokane, Washington

Federal Register Notice:  September 08, 1983

Conditions at listing (December 1982): The Colbert Landfill, owned and operated by Spokane County, is located in Colbert, 10 miles north of Spokane, Washington. For 5 years, the 40-acre landfill accepted liquid solvent wastes and buried them in unlined pits in permeable soil. The surrounding rural area depends on nearby ground water for drinking water and irrigation. No alternative supply is readily available. Some wells are contaminated by the same organic solvents that were dumped at the landfill, which continues to accept municipal wastes.

In September 1981, EPA awarded an $80,000 Cooperative Agreement to Washington, using funds available under the Resource Conservation and Recovery Act, for a remedial investigation to determine the source of ground water contamination. The work was completed in July 1982.

Status (July 1983): Among options being considered for the future are: capping the landfill, conducting long-term monitoring studies of ground water, and providing alternate water supplies to those families using contaminated wells.
