The plight of the population of Flint, Mich. — where a cost-saving switch to a different water source led to 12 deaths and the pervasive threat of lead poisoning — is detailed in the new episode "Poisoned Water." Residents discuss concerns they had early on, which prompted them to contact local officials … whose response propelled them to get in touch with Virginia Tech researchers, who then confirmed the worst. Joe Morton ("Scandal") narrates.
