Foxconn Will Drain 7 Million Gallons of Water Per Day From Lake Michigan to Make LCD Screens (gizmodo.com)
Earlier this week, the Wisconsin Department of Natural Resources granted permission to Taiwanese tech manufacturer Foxconn, best known for assembling Apple's iPhones, to siphon off seven million gallons of water per day from Lake Michigan, despite protests from conservation groups. From a report: The massive diversion of water from the lake will be used to produce LCD screens at the company's planned $10 billion, 20 million square foot manufacturing plant set to be built in Mount Pleasant, Wisconsin. Nearly 2.7 million gallons of the water -- about 39 percent of the daily intake from the factory -- will be lost in the process, primarily from evaporation. The remaining water will be treated and returned to the lake basin.
Wisconsin's DNR noted in a statement that the requested withdrawal will "only amount to a 0.07 percent increase in the total surface water withdrawals from Lake Michigan." For environmentalists in the region, the issue is not so much the diversion for the Foxconn factory itself but rather the precedent it will set for how the lake water can be used. "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," Jennifer Giegerich, the government affairs director for the Wisconsin League of Conservation Voters, warned during a public hearing about the diversion, according to the Wisconsin Gazette.

The real issue is whether or not chemical pollutants are being released in the waste water.
Assuming the wate water is pretreated at the plant to remove manufacturing chemicals, either with clarification or ultrafiltration, there is no issue with significant water "usage".
Evaporation gives me a minor cause for concern, as I assume the evaporation occurs in curing or drying ovens, which allows for the potential of VOC/SVOC releases, but I assume they will have the customary protections used in modern Western plants, such as wet scrubbers and after burners, along with real time participate monitoring and emissions sampling. Generally, permits for any reasonable sized heating operation in Wisconsin requires an extended evaluation and environmental safety plan.
Yes, I'm in the environmental industry in Wisconsin.
