‘Monster Fracks’ Are Getting Far Bigger. And Far Thirstier.

Along a parched stretch of La Salle County, Texas, workers last year dug some 700 feet deep into the ground, seeking freshwater. Millions of gallons of it.

The water wouldn’t supply homes or irrigate farms. It was being used by the petroleum giant BP to frack for fossil fuels. The water would be mixed with sand and toxic chemicals and pumped right back underground — forcing oil and gas from the bedrock.

It was a reminder that to strike oil in America, you need water. Plenty of it.
