The Floridan aquifer system underlies portions of five states. Source: USGS. The Floridan aquifer system spans an area of about 100,000 square miles (260,000 km 2) in the southeastern United States and underlies all of Florida and parts of southern Alabama, southeastern Georgia, and southern South Carolina.

According to the Natural Resources Defense Council's recent study, Florida is one of 14 states predicted to face "high risk" water shortages by the year 2050. [1] The state's water is primarily drawn from the Floridan Aquifer as well as from the St. Johns River, the Suwannee River, and the Ocklawaha River.
In a new report, scientists say the U.S. is facing serious challenges as groundwater is depleted in many areas. They call for a national effort to safeguard aquifers.
For more than a decade, farmers in parts of southwest Georgia haven’t been able to drill new irrigation wells into the Floridian aquifer, but that is set to change in 2025.
Overdrafting in coastal regions can lead to the reduction of water pressure in an aquifer, allowing saltwater intrusion. If saltwater contaminates a freshwater aquifer, that aquifer can no longer be used as a reliable source of freshwater for settlements and cities. Artificial recharge may return fresh water pressure to halt saltwater intrusion.
Michigan and Florida require septic waste to be taken to municipal waste treatment systems. Wisconsin lawmakers need to enact the same requirements.
Depletion of surface and ground water sources for public consumption (including industrial, commercial, and residential) is caused by over-pumping. Aquifers near river systems that are over-pumped have been known to deplete surface water sources as well. Research supporting this has been found in numerous water budgets for a multitude of cities.
Aquifers located in drylands with large farm industries — in places such as northern Mexico, parts of Iran and southern California — are particularly vulnerable to rapid groundwater depletion ...
