Ohio's Department of Natural Resources on Sunday suspended operations at five deep well sites in Youngstown, Ohio, where the injection of water was taking place, while they evaluate seismological data from a rare quake in the area.
The wells are about 9,000 feet deep and are used to dispose of water from oil and gas wells. The process is related to fracking, the controversial injection of chemical-laced water and sand into rock to release oil and gas.
