This city map doesn’t mean you have lead pipes. You should still investigate.

About two weeks ago, WBAL TV got early access to an interactive map that shows hundreds of thousands of homes in Baltimore could have lead drinking water pipes. The dots on the map, published by the Baltimore Service Line Partnership, do not mean all those homes in Baltimore and Baltimore County have lead water pipes. Instead, they indicate that local officials don’t know whether the water pipes are made of lead or another material.
