- mythrwy 5y agoBut sea levels haven't increased very much in either of those places (yet). Certainly not enough to be responsible for the observed effect. What happens is the freshwater aquifers are drained giving the salt/brackish water space to intrude.

Increased storm surges and sea level rises have driven salinity further inland. So you're right that are also other factors, but one root cause is the effect of rising sea levels. Consider what's happening in Miami carefully. https://cnsmaryland.org/2020/11/23/salt-levels-in-floridas-groundwater-rising-at-alarming-rates-nuke-plant-is-one-cause/ https://cnsmaryland.org/2020/11/23/salt-levels-in-floridas-g...
