The leader of the Michigan Department of Environmental Quality came forward on Monday and admitted that critical mistakes were made that lead to the contamination of Flint's drinking water. On Sunday, Dan Wyant, DEQ Director, accepted the mistakes made by the state in handling the situation and said that ‘necessary changes’ are in process.

Flint has been connected again to Detroit's water system with a hope to resolve a health emergency that had occurred due to the switching of water source of the city from Detroit's water system to Flint River.

The city officials have reported that old lead-lined pipes and service lines that transport the city’s water have been corroding. This led to the contamination of the drinking water due to lead. The switch increased the lead levels among children.

The switch was done a day after a bill authorizing $9.35 million was signed by Gov. Rick Snyder to help Flint reconnect to the Detroit system.

The city switched back to Detroit-supplied water on Friday, October 16. The change was made possible by using millions of dollars from the state and Charles Stewart Mott Foundation.

Wyant, in a written statement issued lately, said that the state has enforced the wrong federal standards for the treatment of Flint River water for over 17 months.

Wyant said on Monday, “We are now embarked on an unprecedented effort to safeguard Flint residents and families with near-term, intermediate and long-term actions to protect and educate city residents”.
