Beyond the Flint tragedy: Contaminated drinking water is everywhere in America

The water crisis in Flint, Michigan, became a national news story, and for good reason. Political leaders in the state were finally forced to take steps to stop the poisoning of Flint's drinking water with lead and other toxins, foisted on the community as part of a short-sighted cost-cutting measure. Despite improvements, the future of Flint's water supply is uncertain, but at least that story has brought increased attention to the problem of lead in water in many large cities, including Chicago.
