The head of the U.S. Environmental Protection Agency’s water office told lawmakers Wednesday that Michigan authorities broke federal rules requiring them to add anti-corrosive materials to drinking water pumped into Flint homes, triggering a lead-poisoning crisis.
But critics also accused the EPA of covering up what it knew about that misconduct while Flint residents continued drinking the tainted water.
“If it’s not criminal, I don’t know what is,” Marc Edwards, an engineering professor at Virginia Tech who helped uncover the pollution, told a House Oversight Committee hearing on the crisis.
