COLUMBUS, Ohio (AP) - State officials are weighing rules for storage sites containing wastewater from oil and gas drilling.
The Columbus Dispatch reports that lagoons the size of football fields could store millions of gallons of water used in hydraulic fracturing, or fracking. The chemical-laced fluids are used to free gas trapped deep below the surface. Companies then clean the water so it can be used again.
A spokesman for the Ohio Department of Natural Resources says the state is drafting standards for the construction of the lagoons and their length of use. The agency's officials were directed in the state budget to establish rules and permits for them.
Environmental advocates fear the lagoons could pose a threat to groundwater.
An industry group says the lagoons would have plastic liners to prevent leaks.
