Massive amounts of water, along with other fluids, are used in the fracking process to break rocks, release natural gas and push it to the surface. That water, along with brine pulled from those rocks, comes back to the surface and has to go somewhere. So drillers inject it into underground disposal wells. In Oklahoma, more than 50 billion gallons of wastewater went into disposal wells in 2013 alone, according to the Oklahoma Geological Survey. The fracking process itself also has been linked to earthquakes, though those generally have been smaller than those associated with wastewater disposal.
