Aquifer at risk

National Geographic has a great interactive story on the Ogallala Aquifer. Not only is it a large one, but it is in a central location. The aquifer underlies much of the Great Plains and provides 30% of all of the water used to irrigate US agriculture. Even though it is easy to read and written for a general audience, the story integrates key terms like recharge and unsaturated zone.
