Aquifer That Spreads Across Eight States Nearly Tapped Out

WASHINGTON D.C. (Worthy News)– One of the world's largest aquifers, Ogallala, which covers eight states and 111.8 million acres is nearly tapped out threatening the world's food supply.

The Ogallala Aquifer spreads across eight states, from Texas to South Dakota, covering 111.8 million acres and 175,000 square miles. It’s the fountain of life not only for much of the Texas Panhandle, but also for the entire American Breadbasket of the Great Plains, a highly-sophisticated, amazingly-productive agricultural region that literally helps feed the world.

This catastrophic depletion is primarily manmade. By the early eighties, automated center-pivot irrigation devices were in wide use – those familiar spidery-armed wings processing in a circle atop wheeled tripods. This super-sized sprinkler system allowed farmers to water crops more regularly and effectively, which both significantly increased crop yields and precipitously drained the Ogallala.

Compounding the drawdown has been the nature of the Ogallala itself. Created 10 million years ago, this buried fossil water is–in many places—not recharged by precipitation or surface water. When it’s gone, it’s gone for centuries. — Source
