10 Amazing Facts about Florida’s Aquifer



The Aquifer is a vast underground cave that stores and filters water full of porous limestone rock. Rainfall seeps through the different layers of Florida, which act as natural filters, and enters the aquifer through a process called percolation. When slightly acidic rainwater filters into the limestone, it moves horizontally. Over thousands of years, sections of the limestone rock dissolve, creating channels and caves.

There are two major aquifers in Florida: the Floridian, and the Biscayne. The Floridan Aquifer is the largest and deepest in the state. It underlies beneath the entire state of  Florida and parts of Alabama, Georgia, Mississippi, and South Carolina.




A spring is the natural way for water to leave the Aquifer. A well is the man made way for water to leave the aquifer. You can think of that pipe kind of like a giant straw that sucks water out and then it sends it to your house as fresh water!There are approximately 12,000 wells associated with groundwater systems used for public water supply in Florida. These wells produce water from five major aquifers or aquifer systems.


10 Amazing Facts about Florida’s Aquifer

  1. The average Floridian uses over 100 gallons of water per day!

  2. The aquifer provides 90 percent of drinking water for Floridians.

  3. Florida has more than 900 freshwater springs, one of the largest concentrations of springs on Earth.

  4. Springs are ranked according to the volume of water flowing from the ground.

  5. Discharge from Florida’s springs can range from less than 1 pint per minute (Eighth Magnitude) to more than 64.6 million gallons per day (First Magnitude).

  6. An estimated two quadrillion gallons of water moves through the Floridan aquifer.

  7. Florida has 27 first magnitude springs.

  8. Floridians use 7.2 billion gallons of water everyday.

  9. There are five major aquifers in Florida-The Floridan Aquifer, Sand-and-Gravel Aquifer, Biscayne Aquifer, The Surficial Aquifer, and Intermediate Aquifer.

  10. On average springs in Florida stay at a constant 72 degrees all year long, so they are pretty chilly!
