The Floridan aquifer is the major source of groundwater supply in Florida. The Floridan aquifer is one of the highest producing aquifers in the world and there is no doubt that it is one of the biggest geological assets for the southeastern region of the United States, especially for the state of Florida. Florida Department of Environmental Protection Aquifers information.
Florida Aquifers are multiple layers of limestone under the soil. Limestone is a soft rock that acts like a sponge as it absorbs rainwater. The Aquifer has an underground river that runs through it and Springs are the places where the river reaches the surface. When the underground water levels get too low, hollow spaces between the limestone and underground water can cause the limestone and underground water can cause the limestone to collapse causing a sinkhole.
The Floridian Aquifer System is one of the most productive in the world covering an area of approximately 100,000 square miles in southern Alabama, southeastern Georgia, southern South Carolina, and all of Florida and provides drinking water for the entire state of Florida.
