Lead Service Lines in Minnesota
What you need to know
Minnesota's 6,665 public water systems serve about 5.3 million people. According to the most recent data available, the state has reported 0 known lead service lines across all utilities. This is a positive baseline—but it doesn't mean lead pipes don't exist in older homes.
Lead service lines are the pipes that connect your home to the municipal water main. They were commonly installed before the 1980s, when lead was standard plumbing material. Even if your water system hasn't formally identified lead lines yet, older neighborhoods—especially those built before 1950—are more likely to have them.
Why this matters
Lead in drinking water is a real health concern, especially for children under 6 and pregnant people. The CDC has set a goal of zero lead exposure. Even low levels can affect brain development over time. If your home was built before 1986, there's a reasonable chance your service line or interior plumbing contains lead.
Minnesota has not yet received federal Bipartisan Infrastructure Law (BIL) funding for lead service line replacement as of the latest reporting. However, funding opportunities may expand, and your water utility may have local programs.
What Minnesota water systems are reporting
Most of Minnesota's water utilities—including the smaller systems listed here (Plantation, Old Agency, Onigum Head Start, Palmquist, Northern Lights Casino, and Northside)—have not yet completed detailed lead service line inventories. Many systems are still in the early stages of mapping their pipes.
Next steps for residents
- Contact your water utility directly. Ask: "Do you know if my address has a lead service line?" Provide your street address. Many utilities have records even if they haven't published them publicly yet.
- Get your water tested. If you have a pre-1986 home, ask your utility for a free or low-cost lead test kit, or contact your county health department.
- Know the signs. Dull gray or silver-colored pipes, or pipes that dent easily when scratched, may indicate lead. Take photos and send them to your utility.
- Check the EPA's resources. Visit epa.gov/lead for testing and remediation guidance.
