The Environmental Protection Agency director overseeing a region that includes Flint, Michigan, resigned, NBC News reported.
Susan Hedman offered her resignation effective Feb. 1, and the offer was accepted, the EPA said in a statement Thursday.
The EPA also announced an emergency order requiring Michigan and the city of Flint to take steps to address the drinking water contamination. The agency blamed state and local levels for resisting its recommendations that the water be properly treated.
Flint stopped using Detroit’s water in 2014 to save money, but the Flint River water it used wasn’t properly treated, allowing corroded pipes to leach lead into the drinking water, officials said.
