Some of the water required to fuel our technology addictions will soon be siphoned off of Lake Michigan.

Last summer, Taiwan tech giant Foxconn announced plans to build a $10 billion, 20 million-square-foot manufacturing plant in rural Wisconsin to manufacture LCD screens. On Wednesday, the state Department of Natural Resources approved a request by the surrounding township to divert 7 million gallons of water a day from Lake Michigan to the area, mostly to be used by the plant.

Environmental experts have criticized the diversion. Though, as the DNR points out, it amounts to less than a 1 percent increase in the total surface water withdrawals from Lake Michigan, it would result in a loss of 2.7 million gallons per day, mostly due to evaporation (the rest of the water will be treated and then returned to the lake basin). Environmentalists are also concerned that the decision will set a new precedent allowing the fresh water to be used for predominantly commercial purposes, instead of as drinking water.

“If we allow this to happen, it’s going to happen all over the basin, with other states and then it’s going to be the thirsty states and nations to come,” said Jennifer Giegerich, the government affairs director for the Wisconsin League of Conservation Voters, at a public hearing about the diversion, according to the Wisconsin Gazette .

The Great Lakes contain one-fifth of the Earth’s fresh surface water, making them a valuable and precious resource shared by multiple states and Canadian provinces, and collectively managed under the Great Lakes Compact. Opponents say this decision might violate that agreement.
