Recharging aquifers with water at times of surplus that can be pumped out for later use when other supplies are scarce is a long established technology. Most aquifer recharge systems are designed for municipal water use. Increasingly attention is being given to the potential for using recharged water for agricultural use. Pictured at a recent workshop in Canberra Australia that focused on the potential role for Managed Aquifer storage (MAR) in agriculture, are Bryce Kelly (University of New South Wales, Sydney), Andrew Stone (American Ground Water Trust), Allan Curtis (Charles Sturt University, Albury), Tony Jakeman (Australian National University, Canberra). Stone was invited to attend the event to provide a perspective on aquifer recharge projects in the US.
In the U.S., Idaho pushed to improve the rapidly depleting Eastern Snake Plain Aquifer for much of the last decade.
Many are concerned more water is being pulled from the aquifer than is being put back. If so, the drain could imperil the region’s agriculture that relies on the the underground body of water.
