Duke Study: Rivers Contaminated With Radium and Lead From Thousands of Fracking Wastewater Spills. EcoWatch Sharon Kelly, DeSmogBlog | May 9, 2016 Thousands of oil and gas industry wastewater spills in North Dakota have caused “widespread” contamination from radioactive materials, heavy metals and corrosive salts, putting the health of people and wildlife at risk, researchers from Duke University concluded in a newly released peer-reviewed study.
High levels of lead—the same heavy metal that infamously contaminated water in Flint, Michigan—as well as the radioactive element radium, were discovered near spill sites. One substance, selenium, was found in the state’s waters at levels as high as 35 times the federal thresholds set to protect fish, mussels and other wildlife, including those that people eat.
The pollution was found on land as well as in water. The soils in locations where wastewater spilled were laced with significant levels of radium and even higher levels of radium were discovered in the ground downstream from the spills’ origin points, showing that radioactive materials were soaking into the ground and building up as spills flowed over the ground, the researchers said.
The sheer number of spills in the past several years is striking. All told, the Duke University researchers mapped out a total of more than 3,900 accidental spills of oil and gas wastewater in North Dakota alone……. http://ecowatch.com/2016/05/09/radium-lead-fracking/
