Climate Change Means Some Coastal Groundwater May Soon Be Too Salty to Drink. What Can Cities Do?

Cape May, New Jersey has a long history as a resort town with seafood, ballrooms, and Victorian-era mansions, dating back to the 18th century. The idyllic, seaside town is surrounded by ocean on three sides.

But in the 1950s, the city started to have a problem with its water supply, which comes from groundwater. Saltwater was seeping into wells, making the water undrinkable. The city had to abandon its old wells and drill new ones, over and over again.
