Poisoned Water

Season 44 Episode 10

In this special report, NOVA investigates what happened in Flint, Michigan when local officials changed the city’s water source to save money, but overlooked a critical treatment process. As the water pipes corroded, lead leached into the system, exposing the community—including thousands of children—to dangerous levels of poison. NOVA uncovers the science behind this manmade disaster.
