Do you have a lead service line?

Welcome to the Minnesota Lead Inventory Tracking Tool

This map shows the service line material for buildings connected to public water supplies. A service line is the pipe that brings water from the water main to a building. Enter an address in the search bar to find if the service line material needs to be replaced due to lead.

Residents have been or will be notified by their water system if they have a service line that needs replacement or that may need replacement. These notifications are not an indication that there is an immediate problem with their drinking water. Water systems routinely test drinking water for lead and notify residents separately if there's an issue.

Service Lines

Select a Legislative District:

Water service lines are the pipes that connect the watermain below the street to the plumbing of residences and businesses. Before the lead plumbing ban in 1985 some service lines installed in Minnesota were made of lead. This tool is intended to help Minnesotans determine if they have a lead service line.

Information about lead in drinking water can be found at the Minnesota Department of Health.
Drinking water service lines can be plastic, galvanized steel, copper, ductile iron, or lead. Lead service lines and galvanized steel service lines that were downstream of a lead gooseneck need to be replaced and have a status of Needs Replacement. Galvanized steel service lines are assumed to need replacement unless confirmed otherwise.

More information about service line materials can be found at the Minnesota Department of Health.

There are three categories of service line ownership:
  • Private: The property owner is responsible for the right-of-way portion of the service line and the portion inside the property.
  • Split: The public water supply is responsible for the right-of-way portion while the property owner is responsible inside the property.
  • Utility (Uncommon): The public water supply owns both the right-of-way portion and the portion inside the property.
All Public Water Systems completed and submitted to the state an initial lead service line inventory in October, 2024. These inventories are updated yearly in October. Requirements are available from the Minnesota Department of Health.
