Superfund Record of Decision (EPA Region 5): New Brighton/Arden Hills, Minnesota (Fourth remedial action), (Amendment), August 1989
The New Brighton/Arden Hills site is an area of organic solvent contamination in ground water northwest of Minneapolis, Minnesota. The site includes the cities of New Brighton, Arden Hills, and St. Anthony as well as the Twin Cities Army Ammunition plant. The Record of Decision (ROD) amends a June 1986 ROD calling for the installation of a new well to provide part of the drinking water supply to New Brighton. EPA has concluded that a new well is no longer necessary to protect human health in New Brighton. Originally it was anticipated that low contamination levels in Well No. 7 (one of nine municipal wells) could not be assured and that a replacement well in a deeper aquifer was needed to provide an alternate supply of water. However, further data from Well No. 7 indicate contamination is not increasing. A large water supply will be provided by the U.S. Army to New Brighton as part of a litigation settlement, and a system has been installed by the U.S. Army to prevent further contamination from the suspected sources.
