The Department of Natural Resources has approved a permit for the city of Racine to divert water from Lake Michigan for Foxconn. The Taiwanese tech manufacturing giant plans to use 7 million gallons of water a day for their planned 10 billion dollar LCD display screen factory in rural Racine County.

Racine says it will do its part to treat the water that goes back into Lake Michigan, but many environmentalists worry about the high extent to which Foxconn’s water will evaporate during the manufacturing process, meaning it won’t go back into the Lake.

Plus, questions linger about the exact contaminants that could end up in the water Foxconn uses.

Nina Kravinsky spoke with Clean Wisconsin spokesperson Jon Drewsen about the environmental groups concerns.
