2.2 Billion. That is an estimated 2,200,000,000 gallons of waste water or “produced water” coming out of Colorado fracking wells in 2012 alone, as reported by Environment America. We know that the number of wells increased by about 10% to 53,288 in January of 2015, so the number is probably about 2.6 billion gallons of toxic water that must be disposed of this year.

OKLAHOMA — It’s the million dollar question in Oklahoma: What’s causing all the earthquakes?
There have been a lot of theories about fracking causing earthquakes. But now, the U.S. Geological Survey (USGS) says that fracking, is indeed, to blame. Continue reading
Oklahoma rocketed to the top of the earthquake charts in 2014, tripling the number of 3.0 shakers in California, the one-time undisputed champion of the United States.
But like the steroid scandal that tarnished baseball and ruined the statistical landscape in the 1990s, many scientists are pointing to the introduction of performance-enhancing chemicals to explain the recent 40-fold-plus increase in quakes—in Oklahoma’s case, hydraulic fracturing (fracking).

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. Continue reading
As is the case elsewhere in the world, there is evidence that some central and eastern North America earthquakes have been triggered or caused by human activities that have altered the stress conditions in earth’s crust sufficiently to induce faulting. Activities that have induced felt earthquakes in some geologic environments have included impoundment of water behind dams, injection of fluid into the earth’s crust, extraction of fluid or gas, and removal of rock in mining or quarrying operations. In much of eastern and central North America, the number of Continue reading
