General Motors turns off tap to Flint River water

General Motors is turning their tap off to the Flint River.

"This is strictly due to manufacturing needs," says Jason Lorenz, public information officer for the city of Flint.

Officials say General Motors' water agreement with the city of Flint is going sour because of higher chlorine levels.

"Its chemistry is the issue," says Lauri Elbing with the Flint River Watershed Coalition.

She says the city is using higher chlorine levels to make the city's water drinkable.

GM officials say those higher chlorine levels can cause car corrosion in car parts.

"General Motors is making the best decision that they can to keep making great cars here in Flint," says Elbing.

Elbing says the corrosion is happening now because of the elevated chlorine levels.

"When we were receiving our water from Detroit, the levels were one-part-per-million and they are now three-parts-per-million but the EPA (Environmental Protection Agency) standards is four-parts-per-million or less," says Elbing.

That makes the city's sentiment true.

"The water that is leaving the plant is always assured to be of the top notch quality," says Lorenz.

GM officials were unavailable to talk on-camera Tuesday but told NBC25 News by phone that they will switch back to contracting with Flint for water when the new pipeline from Lake Huron is built.

That should take place by the end of 2016.
