What exactly went wrong in Flint—and what does it mean for the rest of the country?
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.
