Contamination At 3,900 Fracking Spill Sites In N. Dakota Alone
By Sami Grove for Tree Hugger - There's no doubt that fracking has provided a boost to the North Dakota economy in recent years, but at what cost? New research from Duke University scientists hasmapped 3,900 fracking spill sites in North Dakota, analyzing both water and soil around these locations and finding significant, persistent pollution levels that could have serious implications for human and environmental health alike. Researchers found high levels of ammonium, selenium, lead and other toxic contaminants as well as high salt levels and radium, a naturally occurring radioactive element.
