Increased water use in the rapidly growing oil industry in North Dakota's Bakken oil shale region, or play, is surprisingly due not only to oil well development but also to people, according to a recent study by the U.S. Department of Energy's (DOE) Argonne National Laboratory.
Increased oil development in that region in recent years has attracted thousands of oilfield employees. From 2010 to 2012, nearly 24,000 temporary oilfield workers joined the approximately 27,000 permanent residents in Williams Country, the seat of the region's commercial oil industry.
