Where can flooded fields help replenish groundwater?

In California, the amount of water exiting aquifers under the state's most productive farming region far surpasses the amount of water trickling back in. That rampant overdraft has caused land across much of the region to ...

Driving water down nanohighways

Removing water vapor from air and other gas mixtures, which is crucial for many industrial processes and air conditioning, could become cheaper and more effective through polymer membrane technology now developed at KAUST.

US mining sites dump 50M gallons of fouled wastewater daily

Every day many millions of gallons of water loaded with arsenic, lead and other toxic metals flow from some of the most contaminated mining sites in the U.S. and into surrounding streams and ponds without being treated, The ...
