Officials: 4.0 Quake in Northeast Ohio Related To Injection Well

"McDONALD, Ohio - Officials said Saturday they believe the latest earthquake activity in northeast Ohio is related to the injection of wastewater into the ground near a fault line, creating enough pressure to cause seismic activity.

The brine wastewater comes from drilling operations that use the so-called fracking process to extract gas from underground shale. But Ohio Department of Natural Resources Director Jim Zehringer said during a news teleconference that fracking is not causing the quakes."

The Associated Press had the story January 1, 2012.
