The Arkansas Oil and Gas Commission extended its December moratorium on drilling any new wells using the process known as hydraulic fracturing, or fracking, in which millions of gallons of water, combined with chemicals, are injected into wells to fracture shale formations. Sometimes these fluids are disposed of in underground wells. Some believe this disposal method could be the cause of the rash of earthquakes felt around central Arkansas in the past months. A report from KARK says the report will be reviewed in July.

Correction: The moratorium is on the injection of frack waste into underground disposal wells, not the drilling process itself. Apologies for the mix-up.
