context_page_description: The Twin Cities Army Ammunition Plant was a United States Army ammunition plant located in Ramsey County, Minnesota in the current boundaries of the suburbs of Arden Hills and New Brighton, bounded by County Road I to the north, I-35W to the west, U.S. Route 10 to the southwest, County Highway 96 to the south, and Lexington Avenue to the east. The site had 255 buildings across 2,382 acres. Current land redevelopment involves the removal of these buildings.
  The site was added to the National Priorities List as a Superfund site on September 8, 1983. The soil, sediments, groundwater, and surface water surrounding the plant were contaminated with base neutral acids, metals, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, volatile organic compounds, pesticides, cyanide, and explosives. These contaminants entered Rice Creek and from there the ground water in New Brighton.
  Initially, the plant was known as the Twin Cities Ordnance Plant but it was renamed the Twin Cities Arsenal in 1946 and finally, in 1963, the Twin Cities Army Ammunition Plant.
