Federal Geologists: Oklahoma Earthquake ‘Induced’ by Disposal Wells Used in Drilling

Recent earthquakes in Oklahoma, Colorado and New Mexico are tied to wells drilling companies use to dispose of wastewater, federal geologists will argue in a report expected this week.
A USGS team based in Menlo Park, Calif., found that the quake in Colorado and a damaging 5.6-magnitude quake in Oklahoma both were induced by disposal of fracking waste underground.
The study will link disposal wells and Oklahoma’s November 2011 earthquake, a 5.6-magnitude temblor that damaged 200 buildings near east of Oklahoma City, EnergyWire reports.
Regulators in Colorado are urging more study on the link between disposal wells and earthquakes, “but have started to look for seismic risk in permit reviews,” the AP and Denver Post report.
U.S. Geological Survey scientist Justin Rubinstein, co-author of the report — which will be released at the fall meeting of the American Geophysical Union, currently underway in San Francisco — says the data should spur a discussion of disposal wells.
While the evidence is convincing that deep burial of drilling waste can trigger quakes, it also appears that few of the 40,000 disposal wells nationwide have done so, Rubinstein said.
“But I don’t think blowing this off is a good idea,” he said. “It’s a problem we need to understand. There’s been millions of dollars of damage. If you trigger bigger earthquakes, there’s a possibility of worse outcomes.”

Why, IN Earth, would they be pumping the huge amounts of wastewater INTO the subterranean environment! They should clean up the, formerly, freshwater they "use", to the point it meets drinking water standards, and release it back into the SURFACE environment. FRACKING IS FOREVER!
Because they do not want to waste the water,but you are right they should use fresh water.No, there FRACKING FOREVER.
