The Pioneer Press, http://www.twincities.com/mld/twincities/news/16557265.htm, reported on a story concerning the discovery of a 15 plume of tainted underground water. The chemical which authorities have discovered is PFBA, or perfluorobutanoic acid. There have been discoveries of this acid before, once in Lake Elmo in 2002. 3M is known to manufacture the chemical, but officials are looking into where the problems may be. The article also wrote how the public is not reacting at all really. The Star Tribune did not report as in depth as the Pioneer Press article.
