Approximately 66,000 tons of potliners (special linning material used to protect steel pots where molten aluminum is processed) containing cyanide and fluoride were piled on the ground from 1973-1981. Groundwater and soil were contaminated with cyanide and fluoride. About 50,000 people draw drinking water from wells within three miles and upgradient of the site.

The potentially responsible parties (PRPs) conducted cleanup work in 1992 under a Consent Decree agreement with the State of Washington. Actions included: excavating and transporting the source contaminants (50,000 tons of spent potliners and reclaimed alumina) to a permited landfill; covering contaminated soils under the former potliner piles; regrading the soil, fencing the facility, monitoring groundwater and the waters of the Columbia River; implementing institutional controls. All the actions mentioned above have been completed.
