European environmental groups had long fretted about an aging industrial sludge pond near Ajka, Hungary, containing caustic waste from the process that converts bauxite to aluminum. The International Commission for the Protection of the Danube River included the pond on a 2006 watch list of sites “at risk” for accidents that could pollute the Danube ecosystem.

The Bauxite, AR facility was opened as a bauxite refinery in 1952. In 1954 and later in 1959, parts of Alcoa''s chemical processes in East St. Louis, Illinois were transferred to the Bauxite facility. The facility acted as a combination chemical and refining plant until the Arkansas bauxite mines were shut down in 1990.
