Anniston Army Depot (ANAD) is a major United States Army facility for the production and repair of ground combat vehicles, overhaul of Small Arms Weapon Systems and the storage of chemical weapons, aka the Anniston Chemical Activity. The depot is located in Bynum, Alabama. It was placed on the NPL Superfundlist in 1990 because of soil and groundwater contamination with antimony, chromium, lead, thallium and trichloroethylene.
