Fracking may be contaminating a Pennsylvania river with radioactive waste, a Duke University study to be published this week shows.
Scientists found elevated levels of radioactivity in river water at a site where treated fracking wastewater from oil and gas production sites in western Pennsylvania’s Marcellus shale is released into a creek.
The natural gas-rich Marcellus shale is seeing a drilling boom, part of a nationwide rush to use hydraulic fracturing, or fracking, techniques to extract shale gas and oil.
Studies have shown that energy production, including the waste water associated with fracking — a method of injecting chemicals, sand and water deep underground to crack rock formations to release oil and natural gas — may release significant fugitive methane emissions, helping to drive climate change.
