The Minnesota Department of Health has detected low levels of the chemical perfluorobutanoic acid (PFBA) in municipal wells in Woodbury, Cottage Grove, Newport, St. Paul Park, South St. Paul and Hastings. The contamination in all of these cities, except Woodbury, appears to be occurring in an area of groundwater that is separate from the one in Lake Elmo and Oakdale. The source of this new area of contamination is under investigation.
