The Fight for Flint

The city of Flint, Michigan is in crisis. Findings of dangerously high levels of lead in the city's water prompted President Barack Obama to sign an emergency declaration and order aid from Federal Emergency Management Agency and the Department of Homeland Security. The research on Flint's municipal water quality was conducted by a team of 25 researches from Virginia Tech -- a group also largely responsible for the situation there gaining national attention. Today we'll speak with one of the leaders of that team about their work in Flint and the dangers facing other cities with aging infrastructure.
