The 2017 Minnesota Legislature directed the Minnesota Department of Health (MDH) to “conduct an analysis to determine the scope of the lead problem in Minnesota’s water and the cost to eliminate lead exposure in drinking water.” In this report, Assessment of Eliminating Lead in Minnesota Drinking Water, MDH assesses the scope of the lead problem by examining the extent of lead already in water systems as well as factors that allow lead to get in drinking water. However, because drinking water systems across the state are diverse and have varying requirements and resource needs, broad estimates are used to gauge costs.
