In the center of the Hanford Site is a massive landfill, the Environmental Restoration Disposal Faculty (ERDF). Prior to ERDF, there was no storage facility to deal with the hundreds of controlled sites scattered around that contained radiological hazards.  Built in 1996, the site accepts low-level radioactive, hazardous, and mixed waste from cleanup activities at Hanford. Soil that is contaminated, waste that has been dug up, and debris from building demolitions are transported to ERDF for permanent disposal.  No non-Hanford waste is accepted. ERDF covers 107 acres with a capacity of 18 million tons. To date more than 15 million tons of contaminated material has been disposed of in the facility. Each day up to 600 truckloads of waste can be placed into the facility.


A key feature of ERDF is a special liner consisting of multiple layers of plastic and other impermeable materials along with a system to collect and remove liquids as they drain through the waste materials. No liquids waste is transported to ERDF, but rain and snow, as well as water used for dust control, enters the site. This system keeps Hanford waste away from the Columbia River, and from moving off site.
