Rare oil-patch hotspot emerges in Oklahoma

Washington

BRIAN Kalt's got a pretty funky plan to stop the surge in earthquakes in Oklahoma and save the state's reeling oil industry.

The key is to come up with an alternative to dumping drillers' waste water right back into the ground, so Mr Kalt's little company will extract the salt particles, release the purified water into rivers and, then, to defray costs and make the scheme economically viable, sell the salt for use on snowy roads and in industrial machinery. (With a little more scrubbing, it could even be served on kitchen tables.) Mr Kalt says he's already signed tentative deals with salt companies and is, naturally, excited about his innovation.
