In a segment of a regular news update on water issues around the world, Paul Westerhoff, a professor in the  School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, voices concern about a shortage of adequate water supplies to sustain the increasingly critical semiconductor manufacturing industry in the U.S. Some semiconductor fabrication facilities use tens of millions of gallons a day, raising serious doubt about the ability of many of fabrication operations to maintain their production in water-stressed regions such as Arizona. Westerhoff and his colleagues are researching water-reuse technologies that could help to adequately maintain the operations of fabrication facilities.
