A coalition of Colorado environmental groups has sued the Environmental Protection Agency ( the Environmental Protection Agency ), claiming that the government has not sufficiently regulated waste disposal connected to oil and gas drilling. Those rules, issued by the Interior Department, would apply only to oil and gas drilling on federal lands. The lawsuit focuses particularly on the disposal of waste water from fracking. Such waste is currently sent to underground wells; a process that has been connected to an increased rate of earthquakes in states including Oklahoma , Ohio and Colorado . The lawsuit calls for a ban on the dumping of waste water in areas where it could pollute drinking water and landfills. Last year , the US administration passed measures intended to limit the potential for water contamination as a result of fracking, however those measures only applied to fracking on federal lands.
