In this Dec. 16, 2016 photo, David Nelms, a hydrologist with the U.S. Geological Survey, gestures to an extensometer that's being installed in Suffolk, Virginia. The gauge, under the black plastic trash bag, reaches 2,000 feet into the ground and measures ground levels. The local sanitation department plans to inject treated wastewater into the aquifer, which could cause ground levels to rise and serve as a tool against sea-level rise. (AP Photo/ Ben Finley)
