ST. LOUIS (AP) — In many cities, no one knows where the lead pipes lie underground. That’s important because lead pipes contaminate drinking water. After the lead crisis in Flint, officials in Michigan accelerated efforts to locate their pipes, a first step toward removal.

But other places are moving more slowly.

That means as billions of dollars in new federal funding becomes available to address the problem, some places are in a better position than others to quickly apply for funds and start digging.

Those that wait are at risk of being left behind.

“The issue right now is we want to reduce the time that vulnerable folks are living with lead exposure,” said Eric Schwartz, co-CEO of BlueConduit, which uses computer modeling to help communities predict where their lead pipes are.
