The FBI is now investigating the water crisis in Flint, Michigan

Flint Michigan Water Supply

The FBI is now taking part in the US investigation into Flint, Michigan’s water contamination crisis, a spokeswoman revealed on Tuesday.

Gina Balaya, a spokeswoman for the U.S. Attorney’s Office in Detroit, said in an email that federal prosecutors in Michigan are “working with a multi-agency investigation team on the Flint water contamination matter, including the FBI, the US Postal Inspection Service, the EPA’s Office of Inspector General … and the EPA’s Criminal Investigation Division.”

The city switched its source of tap water from Detroit’s system to the Flint River in April 2014. At the time of the change the city was under the control of a state-appointed emergency manager.

The water from the Flint River was more corrosive than the Detroit water supply. The new water supply leached more lead from the city pipes, which has led to city-wide contamination.

Last week, Michigan Attorney General Bill Schuette named a special prosecutor and investigator to look into possible crimes stemming from the matter.

Despite toxic water, residents in Flint, Michigan as of last week continued to receive water bills. Adding insult to injury, residents in the area pay some of the highest water bills in the Midwest.
