The City of Mound and the Minnesota Department of Health (MDH) routinely conduct water analysis testing to monitor water quality.  Recent testing indicated the city’s drinking water supply complies with the Safe Drinking Water Act primary drinking water standards.  However, the testing indicated elevated levels of manganese greater than the MDH recommended health advisory guideline levels.   

Manganese occurs naturally in rocks and soil across Minnesota and is often found in Minnesota ground and surface water. Your body needs some manganese to stay healthy, but too much can be harmful. You can find more information on the MDH webpage about Manganese in Drinking Water.
