Climate change means some coastal groundwater may soon be too salty to drink. What can cities do – Cape May, New Jersey, USA

Cape May solved its problem with desalination. Could the rest of the world follow suit?

The only feasible solution was desalination
. “We’re looking to really step it up 
[with] the next plant 
 that’ll be sustainable for 
 the next 50 plus years,” Mendo said.

Plant operator Joe Mendo says 70 percent of the water that goes in comes out as fresh water. The other 30 percent is concentrated salt water that goes into a nearby creek, which, he said, is not harmful because it is far less salty than actual salt water. [
