New PBS documentary, ‘Poisoned Water,’ explores exactly what went wrong in Flint, Mich.

The city of Flint, Mich., wanted to save some money, so under the authority of a state-appointed emergency manager it switched its municipal water supply from Lake Huron to the Flint River.

What resulted was stunning and tragic, as unforeseen chemical reactions exposed thousands of people – including children – to lead poisoning. Two subsequent outbreaks of Legionnaires’ Disease, probably caused by the tainted water, took 12 lives.

“Poisoned Water,” a new one-hour documentary from PBS science series NOVA, looks at what went wrong. Joe Morton narrates. It premieres at 9 p.m. Wednesday, May 31, on local station KVIE.
