A Penn State University study has found the chemical makeup of flow back water from fracking wells in the Marcellus Shale Region of Pennsylvania, concluding that the radio active materials picked up by the fracking water are from brines formed 4 millions years ago during the Paleozoic era. The water contained barium and radium which are radioactive materials found naturally 8,000 feet below the surface of the earth.
So elements deposited into the earth hundreds of millions of years ago are now being picked up by the fracking fluid and brought to the surface.
“Even if it’s diluted quite a bit, it’s still going to be above the drinking water limits,”he said. “There’s been very little research into this.” Arthur W. Rose, one of the professors who did the study.
This brings about more concern to the flowback water. There has been very little studied on what the fracking water picks up while it is miles below the surface of the earth. These radioactive material are of great concern because once they reach the surface they become a hazard for humans and the environment especially if improperly disposed of.
