By far the largest ‘space’ available for water storage is underground, especially in overdrafted groundwater systems. Although the history of groundwater development is characterized mainly by efforts to find and pump groundwater, the future of groundwater will hinge on working as hard on recharging groundwater as we do on pumping it. A new age of groundwater recharge and sustainable management will come easier if we more fully recognize the benefits of recharge, including the obvious benefits and some that are less obvious.
