Filling Up on Empty

โ€œWe are sucking our aquifers dry,โ€ the headline reads. Could this be a good thing?

The bad effects of declining groundwater levels are known: land subsidence, the cost of pumping from deeper wells, the drying up of surface springs and streams. But there is a potential gain as well. Using up one resource, the water stored under the ground, we are creating another: storage space far greater than any conceivable new dam could provide. โ€œHistorical overdraft,โ€ writes engineer Jay Lund, โ€œmay be an effective means of underground reservoir construction.โ€ If so, we have been building like mad.
