Even as the worst drought in decades ravages California, and its cities face mandatory cuts in water use, millions of pounds of thirsty crops like oranges, tomatoes and almonds continue to stream out of the state and onto the nations grocery shelves.
But the way that California farmers have pulled off that feat is a case study in the unwise use of natural resources, many experts say. Farmers are drilling wells at a feverish pace and pumping billions of gallons of water from the ground, depleting a resource that was critically endangered even before the drought, now in its fourth year, began.
As a drilling frenzy unfolds across the Central Valley, Californias agricultural heartland, the consequences of the overuse of groundwater are becoming plain to see.
In some places, water tables have dropped 50 feet or more in just a few years. With less underground water to buoy it, the land surface is sinking as much as a foot a year in spots, causing roads to buckle and bridges to crack. Shallow wells have run dry, depriving several poor communities of water.
... for decades, California farmers have been overdrawing many of the states water-holding formations its aquifers even in years when surface water for irrigation was plentiful, the equivalent of overdrawing a checking account.
