The head of the Michigan health department has been charged with involuntary manslaughter after he failed to alert the public to an outbreak of Legionnaires' disease in Flint, Michigan, linked to the city's lead-contaminated water crisis, the Associated Press reported.
The Michigan attorney general led a probe which looked at the decision by officials to switch the city's water supply to untreated Flint River water in 2014 in an effort to save money.
Criminal charges have already been filed against 13 current or former government officials, according to the AP.
In addition to the Legionnaire's outbreak, which resulted in a reported 12 deaths between 2014 and 2015, Flint's tainted water also resulted in about 99,000 residents who suffered from heightened blood lead levels.
In January 2016, a representative at the Environmental Protection Agency's Lead Information Center Hotline told Mic that the EPA labels water "toxic waste" when the lead contaminant concentration is 5,000 parts per billion.
