Groundwater drilled by people, used for agriculture or urban supplies and then discarded into drainages now contributes more water to the oceans than melting from each of the world’s largest ice caps.
People aren’t just misusing groundwater, they are flooding their own coasts and cities in the process, Famiglietti warns. That means they are also imperiling some of the world’s most important food-producing lowlands in the Nile and Mekong deltas and cities from Shanghai to New York. Once in the oceans, of course, groundwater will never again be suitable for drinking and human use without expensive and energy-sucking treatment or through the natural cycle of evaporating and precipitating as rain. But even then, it may no longer fall where it is needed most. Groundwater “is an intergenerational resource that is being poorly managed, if managed at all,” the study states, “at tremendous and exceptionally undervalued cost to future generations.”
