LANSING, MI (AP)-- A top Democrat in Michigan's Legislature is calling for hearings and an audit to probe the state's oversight of drinking water in Flint.
Senate Minority Leader Jim Ananich says environmental regulators' actions are "extremely troubling."
Department of Environmental Quality Director Dan Wyant said Monday a mistake was made and federal drinking water rules were not followed properly when Flint switched its water source. He reassigned the chief of the Office of Drinking Water and Municipal Assistance.
Ananich said Tuesday that legislative oversight committees should hold hearings. He also sent a letter to Michigan's auditor general asking that he investigate further as part of an already-underway audit of the drinking water office.
Flint has reconnected to Detroit's system to resolve the lead health emergency spurred by a switch to river water.
