color-coded lines indicating (to the best of our knowledge) which service areas have the potential to contain lead service lines and which are do not. This information is primarily based on the age of the pipe installation. We do not have a comprehensive database on which addresses are confirmed to have lead service lines.

Click the "Service Map" icon below to view a more detailed version of the map in .PDF format. Scroll through the file to find your neighborhood and then zoom in (press CTRL and the "+" sign to zoom) on the address to see where lead pipe may be present.
