Flint has reversed it's decision to use river water for its system in its city and reconnected to Detroit's system after it was found that the river water left children with increased levels of lead.

Local government said that Detroit water would be introduced into the system through the evening and that the transition would be completed within three weeks, according to the Associated Press. The announcement comes a day after Gov. Rick Snyder approved $9.3 million in aid toward the $12 million that returning to Detroit's system will cost through June.

"The money from the state to begin fixing Flint water by reconnecting to Detroit is just a start - a down payment," Flint Mayor Dayne Walling said in a statement. "I am not going to stop until every drop of drinking water in Flint is 100 percent safe."

Flint stopped getting its water from Detroit's system last year in an effort aimed at saving money, reported Michigan Live. Water from the Flint River was supposed to act as an interim supply source until the city could join a new system using water from Lake Huron, which is scheduled to be completed next year.

Officials have long maintained their stance that the water was safe, but after complaints from the public, as well as city-sponsored tests proving otherwise, the government was forced to make a switch.

"Reconnecting to the Great Lakes Water Authority is only the first step, as the state will continue testing and inspections to ensure Flint families and children have clean water in their homes and schools," Snyder said in a statement, according to ABC News

Even though the city is switching back to Detroit water, officials warned Flint residents that they might still see discoloration or notice some taste and odor issues before the transition is complete.
