Al Jazeera America's Laura Gottesdenier has a nice article looking at the contamination of agricultural lands in North Dakota by wastewater from fracking.
Last summer, in a wet, remote section of farm country in Bottineau County, landowner Mike Artz and his two neighbors discovered that a ruptured pipeline was spewing contaminated wastewater into his crop fields.
“We saw all this oil on the low area, and all this salt water spread out beyond it,” said his neighbor Larry Peterson, who works as a farmer and an oil-shale contractor. “The water ran out into the wetland.”
It was August, and all across Artz’s farm the barley crop was just reaching maturity. But near the spill, the dead stalks had undeveloped kernels, which, the farmers knew, meant that the barley had been contaminated weeks earlier.
Soon after, state testing of the wetlands showed that chloride levels were so high, they exceeded the range of the test strips. The North Dakota Department of Health estimated that between 400 to 600 barrels of wastewater, the equivalent of 16,800 to 25,200 gallons, had seeped into the ground.
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.”
[. . .] Bottineau County offers an unusual, decades-long test case, since the region has a long history of contamination and a plethora of aging wells, tanks, pipelines, disposal sites and other infrastructure left from North Dakota’s earlier oil booms in the 1930s, 1950s and 1980s. And the experiment’s not over yet. At a recent meeting, Lynn Helms, director of the North Dakota Industrial Commission’s Oil and Gas Division, announced that a new wave of production is headed to Bottineau in 2015.
