People of the Great Plains have been drawing on the underground water of the sprawling Ogallala Aquifer for centuries. But it took a failed tinkerer's single inspired invention in 1948—the center-pivot sprinkler system—to precipitate this century's looming crisis over access to potable water, on land stretching from South Dakota to Texas and from Colorado almost to Iowa. The sprinkler (followed by ever more sophisticated water extraction systems) sprayed water across fields of corn and cotton more efficiently, reports Ashworth (
The Late, Great Lakes). But this in turn led to an increase in land under cultivation—a situation that, compounded by suburban sprawl in the southwest, means that for the past half-century, water that had collected below the surface over many millennia is now being consumed far more quickly than nature can replenish it. Ashworth recounts some conservation efforts that could achieve a "tenuous balance" between supply and demand, but he doesn't hold out much hope that years of rampant mining of the aquifer's once-vast liquid resources can be reversed. Firsthand vignettes about efforts to introduce dryland farming techniques and reintroduce buffalo herds add some zip to the narrative, but for a doomsday book about a dire situation, the text is often pretty dry.

From Booklist
Hidden below the eight states that compose the Great Plains lies a vast ocean known as the Ogallala Aquifer. Supporting 14 million acres of crops that represent one-fifth of the country's total agricultural harvest, this primary source of groundwater affects everything from the food we eat to the clothing we wear. Deep enough to fill Lake Erie nine times over, it is immense, but it is not infinite, and this precious aquifer is going dry. It is a question of when, not if, and the management of this essential resource will be one of the most daunting challenges of the twenty-first century. Tracing the dramatic history of the aquifer from its Ice Age formation to its current precarious state, Ashworth presents a state-by-state montage of the people who have both championed its preservation and orchestrated its destruction. Ashworth deftly clarifies and personalizes the critical economic, environmental, and humanitarian issues at stake, forcefully connecting the geology of the planet's past with the ecology of this country's future.
