This an excerpt from ENS on shale extraction and the environment in the Allegheny watershed;
“The study, Impacts of Shale Gas Wastewater Disposal on Water Quality in Western Pennsylvania, was conducted over a period of two years from the summer of 2010 to the fall of 2012 and analyzed water samples discharged downstream of the Josephine Brine Treatment Facility into Blacklick Creek in the Allegheny River watershed, according to StateImpact, a project of National Public Radio. Sediment found in the creek contained levels of radium that were 200 times greater than normal levels, along with high levels of salts like chloride and bromide in the surface water.
These elements are naturally occurring and released during the fracking process. Radioactive brine, known as “flowback,” is typically shipped to centers like the Josephine Brine Treatment Facility or injected into wells.
“The recent Duke University study that found increased levels of radiation in a Pennsylvania creek linked to liquid waste from oil and gas drilling should serve as a wakeup call to Governor Kasich,” said Food & Water Watch Ohio organizer Alison Auciello. “It should also make him think twice about accepting waste from oil and gas drilling operations in other states.”
Last year, more than 14 million barrels of toxic waste from oil and gas drilling were injected into the ground in Ohio’s Class II disposal wells, with more than half of the wastewater coming from out-of-state. These injection wells, essential to the fracking industry, pose a series of threats to groundwater supplies and human health, and have been linked to increased seismic activity.”
