The City of Detroit’s drinking water is clean and safe to drink and it meets or exceeds all federal and state regulatory standards under the Safe Drinking Water Act. The Detroit Water and Sewerage Department (DWSD) tested drinking water in 2019 for lead -- under the most stringent Lead and Copper Rule (Michigan) in the nation -- and found that the sampling of the homes tested were below the EPA’s action level for lead in drinking water. The water leaving the treatment plants does not contain lead, nor do the water mains, but lead can be released into drinking water from corrosion in service lines and household plumbing that contain lead. The water provided to DWSD customers contains a corrosion inhibitor to reduce corrosion of lead and other pipe materials into drinking water. If present, elevated levels of lead can cause serious health and development problems, especially for pregnant women and young children.
