Redevelopment at the Site

The 240-acre Kaiser Aluminum (Mead Works) Superfund site is an aluminum reduction facility located near Mead, Washington. Operators disposed of pot linings, creating a 6-acre pile on the plant property. In 1978, sampling detected cyanide and fluoride in several private drinking water wells and an aquifer that supplies water to the Little Spokane River. Tests linked contamination to past activities at the site, and EPA added it to the Superfund program's National Priorities List (NPL) in 1983. As part of site cleanup, Kaiser Aluminum supplied an alternate water source to residents with contaminated wells, constructed a cap to contain contamination and halted on-site disposal of waste pot liners. Kaiser Aluminum went bankrupt in 2004, and a Public Custodial Trust, established through the bankruptcy, took ownership of the property and managed cleanup activities. The Trust sold the property in 2012, and the developer has plans to turn the property into an industrial complex.
