Groundwater in the Colorado River basin won't run out — but eventually we won’t be able to get at it, scientists warn

Scientists studying the Colorado River basin have some sobering news: while the region's groundwater isn’t about to vanish entirely, we’re reaching a tipping point where accessing it will become prohibitively expensive. Over the past two decades, the basin has lost as much water as Lake Mead holds—a staggering amount—and now, the cost of pumping what’s left could soon outstrip practicality.
