State study finds new health hazards in drinking water


A state drinking water study has found signs of new contaminants that threaten human health in a Wisconsin county where a large number of wells were already tainted by pollutants linked to manure from large dairy farms. Signs of salmonella and rotavirus were found in 11 of 30 private wells tested recently in Kewaunee County, the state Department of Health Services and Department of Natural Resources said.
