Fracking: environmental groups sue EPA in call for strict rules on waste

Fracking has led to hundreds of billions of gallons of waste full of toxic chemicals - yet the process is hardly subject to any standards, coalition says

Frack waste has triggered earthquakes from Ohio to Oklahoma, and fouled rivers in Pennsylvania to North Dakota - and now the Obama administration is being sued by environmental groups to crack down on the industry.

A coalition of environmental groups sued the Environmental Protection Agency on Wednesday to demand a strong uniform standard for the transportation, storage and disposal of frack waste.
