Superfund Site: FORT LEWIS (LANDFILL NO. 5)

Superfund Site Profile


The 180-acre Fort Lewis (Landfill No. 5) site is located in Tillicum, Washington. It includes a 60-acre closed portion of the active Fort Lewis Landfill No. 5. From 1967 through 1990, the landfill accepted mixed municipal solid waste (industrial, commercial, residential), demolition waste and dewatered sludge from the Fort Lewis wastewater treatment plant. These activities contaminated groundwater with hazardous chemicals. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 1995. Operation and maintenance activities and monitoring are ongoing.
