As state officials continued to downplay the lead risk to Flint’s children, last August, research scientists from Virginia Tech got involved. They warned people in the Michigan city to stop drinking the tap water.

Tests showed high levels of lead in that water – and lead is especially harmful to young children. It can lead to conditions such as a lower IQ and attention problems. And once that lead gets into a kid’s blood, the damage is done. You can’t reverse it.

In this story, we’ll hear from the researchers and meet a Flint pediatrician who risked her reputation to change the city’s course.
