Lead Service Map

Prior to 1950, lead was commonly used in the manufacture and installation of water service pipes and some private water service lines are made of lead. If too much lead enters your body, it can pose significant health risks, especially to children. For more information, refer to our Sources of Lead page.

The following map indicates, in yellow, properties within the City of Boston that have private lead service pipes. If your property has a lead service pipe, consider the following:

  • Owners of properties with lead service pipes can call the BWSC Lead Hotline at (617) 989-7888.
  • One, two and three family homes may be eligible for BWSC's Lead Replacement Incentive Program.
  • Tenants, whose building has a lead water service should contact their landlord or building manager.

Instructions

  1. Begin entering an address in the search box, then select an address from the dropdown. Properties with lead service are highlighted in yellow and listed below the map.
  2. Use the plus and minus buttons in the upper left corner to zoom in and out.
