To date, over 25,000 children in Flint, Michigan, have been exposed to lead contamination from the city’s water supply. How did the water get that way?

Gov. Rick Snyder declared a state of emergency for Flint and Genesee County Tuesday as a result of the contaminated drinking water crisis, on the same day the U.S. Attorney’s Office confirmed it is investigating the contamination of Flint’s drinking water supply.
