Is it true that in Florida, the aquifers are especially close to the surface?
In some parts of the state. Aquifers are fed from freshwater rivers and streams which are fed from the seas. If the seas become polluted, the aquifers, while last in line, will eventually become contaminated as well. Rain also feeds the aquifers, but they’re primarily filled from the freshwater sources.
In places like Weeki Watchee springs, the aquifers are very near to the surface and divers can actually go through limestone cave systems to get into them.
I can get to water with a shovel in less than a minute.
