North Dakota fights wastewater legacy
"North Dakota is in the midst of an oil boom. Farmers are coping with the environmental and financial costs of wastewater spills from the drilling."
Wastewater, known as saltwater because of its high salinity, is a by-product of oil drilling, which has been a boom-and-bust industry in North Dakota since at least the 1930s. Far saltier than ocean water, this wastewater is toxic enough to sterilize land and poison animals that mistakenly drink it. You never see a saltwater spill produce again, Artz said, referring to the land affected by the contamination. Maybe this will be the first, but I doubt it.
While the boom has brought wealth, the rapid pace of extraction has sparked fears among the states farmers and ranchers about the long-term costs and consequences of land and water contamination, especially because hydraulic fracturing, known as fracking, produces far more wastewater than past drilling techniques. (The process, which has exploded in North Dakota since 2008, requires injecting into each well millions of gallons of water mixed with chemicals at high pressure in order to break up the shale underneath.) Recent spills, such as Julys massive, million-gallon wastewater spill on the Fort Berthold Indian Reservation, in western North Dakota, have further stoked fears of future contamination.
