The Water Wars of Arizona
“With less rain and snow reaching the desert floor, overpumping has rendered a semi-renewable resource finite, touching off the kind of resource war perhaps more familiar to coal camps and oil boomtowns. Hydrogeologists use the phrase “groundwater mining” to describe situations in which the rate of water withdrawal exceeds the rate of replenishment. For some, the metaphor offers a stark lesson. “If we know we’re mining the water, let’s just say it,” said Richard Searle, when I visited at his ranch outside Willcox. At 63, Searle still cuts a frontiersman’s profile; a cutting-horse competitor and former bank manager, he is descended from a prominent ranching family and formerly served as county supervisor. Part of the reason groundwater mining in the valley hadn’t forced a reckoning earlier, he said, was that water was ubiquitous to the point of being invisible. Local farmers were never required to put meters on their wells, he pointed out, which meant that nobody knew exactly how much water was being pumped, much less how much was left. “Long term, people say we should search for a solution,” he said, “but they don’t want to be the ones to suffer.””
