LeeAnne Walters led a citizens’ movement that tested the tap water in Flint, Michigan, and exposed the Flint water crisis. The results showed that one in six homes had lead levels in water that exceeded the EPA’s safety threshold. Walters’ persistence compelled the local, state, and federal governments to take action and ensure that residents of Flint have access to clean water. Narrated by Robert Redford, Flipping the Switch shows how ordinary people can effect extraordinary change. LeeAnne was a winner of the prestigious 2018 Goldman Environmental Prize.
