The problem is not so much foxconn or one entity. The problem is everyone wants that water, everyone... If you open the floodgates to using that for industrial purposes the largest supply of freshwater in the world will be drained and/or polluted within a few decades.

An interesting use case is a suburb of Milwaukee called Waukesha which happens to be out of clean drinking water they are reduced to using radon laced wells. The problem pronounces itself when they can’t take water from Lake Michigan because Waukesha is over the Mississippi water basin. Spoiler: they got permission to use the water
