Despite complaints of foul-smelling, discolored water, outbreaks of Legionnaires disease, and doubled rates of lead poisoning, officials refused to acknowledge issues with the water supply until last fall.

An investigation into the roots of the crisis by Schuette’s office uncovered documents that allegedly indicate that Glasgow tampered with water quality reports. In an interview last mont, Glasgow said that he did so at Prysby and Busch’s request, Eliott McLaughlin reports for CNN. The two state officials are also accused of tampering with evidence to cover the lead problems. If the three men are found guilty of all charges, they could face maximum punishments of thousands of dollars in fines and multiple years in prison.

Schuette has pledged to continue investigating the crisis, stating that these charges "are only the beginning," McLaughlin reports. However, many Flint residents whose outcries were ignored for more than a year say the charges aren’t harsh enough.

"I won't rest until the governor is charged. It was his person who pushed the change of water supply through and he knew there were problems but did nothing," Flint resident Nakiya Wakes tells McLaughlin. "We are still suffering here. And his higher-ups in this mess need to be held responsible, too."

Michigan Governor Rick Snyder has been accused of being too slow to react to the crisis, but  has since defended his response, McLaughlin reports. Earlier this week, Snyder pledged to spend the next month only drinking water from Flint in an attempt to prove to the city’s residents that the water, which is once again flowing from Lake Huron, is once again safe to drink. Still, skepticism remains among many of the victims of the toxic water.

"We're still drinking bottled water, using the filters to wash our hands, hoping that we're not being poisoned by the shower," Flint resident Laura McIntyre tells McLaughlin. "It's just been so discouraging and disheartening."
