Rex Buchanan, interim director of the Kansas Geological Survey at the University of Kansas, "said fracking has been going on in Kansas since the 1940s, but the recent innovation of horizontal drilling—instead of vertical—requires more water," Schuessler writes. "The wastewater is injected into disposal wells—'not exactly where it came from,' Buchanan said. He added that the earthquakes are likely being caused by the wastewater disposal wells, not the act of drilling itself," He told Schuessler, “In Kansas, you produce a lot more saltwater than you do oil in the oil and gas production process. We’re dealing with much greater volumes of water than ten years ago.”
