Might the ground water in many parts of southern Florida?

Question

become polluted with ocean water long before the coastline begins to rise? Pls: GEOLOGIC answers, not Bushwax.

Beg your pardon, the coastline is defined by the level of the water. From the Enc. Brit. 'the coastline often recedes prior to a tsunami ..........'

Answer 1

Well, lets assume you really meant to say - before the level of the ocean begins to rise, because the coastline is the land part and it isn't going to rise. And no, the ground water is not going to be contaminated with salt water until AFTER the ocean level starts to rise because the hydrostatic pressure of the raised sea level is what will drive the salt into the ground water.
