Confirmed: California Aquifers Contaminated With Billions Of Gallons of Fracking Wastewater

Update 02/11/15: The problems with California’s underground injection control program are far worse than originally reported. It has now been revealed that California regulators with DOGGR permitted hundreds of wastewater injection wells and thousands more wells injecting fluids for “enhanced oil recovery” into aquifers protected under the federal Safe Drinking Water Act.

Original post: After California state regulators shut down 11 fracking wastewater injection wells last July over concerns that the wastewater might have contaminated aquifers used for drinking water and farm irrigation, the EPA ordered a report within 60 days. Continue reading

And then, we saw it…

Stillwater, OK. It was July. We were driving in unfamiliar territory in central Oklahoma, navigating through dusty, hot ranching communities and along miles of barbwire fence that separated us from distant livestock. The GPS spouted off a series of commands that led to narrower roads with horses, cattle, and homes closer to the fence lines. A mile or so beyond where the pavement ended, we saw it.

Wastewater Injection Triggered Oklahoma’s Earthquake Cascade

One of Oklahoma’s biggest man-made earthquakes, caused by fracking-linked wastewater injection, triggered an earthquake cascade that led to the damaging magnitude-5.7 Prague quake that struck on Nov. 6, 2011, a new study confirms.

The findings suggest that even small man-made earthquakes, such as those of just a magnitude 1 or magnitude 2, can trigger damaging quakes, said study co-author Elizabeth Cochran, a seismologist with the U.S. Geological Survey.

“Even if wastewater injection only directly affects a low-hazard fault, those smaller events could trigger an event on a larger fault nearby,” she told Live Science. Continue reading

Man-Made Earthquakes

The number of earthquakes has increased dramatically over the past few years within the central and eastern United States. Nearly 450 earthquakes magnitude 3.0 and larger occurred in the four years from 2010-2013, over 100 per year on average, compared with an average rate of 20 earthquakes per year observed from 1970-2000.
