The pipe that connects a home to the water main is called a service line. In the United States, between 6
million to 12 million service lines are made of lead. These lead service lines are concentrated in the Upper
Midwest (as well as in low-income neighborhoods
and communities of color—not shown). When these lead pipes corrode, lead leaks into drinking water, which
can have a devastating long-term effect on people, especially children.
