The Floridan Aquifer is a far ways down …
Especially on the south peninsula where it’s buried a thousand feet.
But poke a hole in it with a pipe and its water flows straight to the surface, sort of like an artesian spring. As prodigious a water source as that sounds, ever so tempting to tap, don’t forget that it’s packed with a bunch of dissolved solids too.
Or in other words, salty.
Florida’s freshwater floats on a sea of saltwater below!
