- Floridan Aquifer
The Floridan Aquifer is a portion of the principal
artesian aquiferthat extends into Florida[cite web

first=] and is composed of
carbonaterock and located beneath the coastal regions of the Southeastern United Statesand is one of the world's most productive aquifers. [ [http://capp.water.usgs.gov/gwa/ch_g/G-text6.html USGS Ground Water Atlas of the United States HA 730-G] ] It is under all of Florida as well as large parts of coastal Georgia and areas of coastal Alabamaand South Carolina. (See figure)
geologistVictor Timothy Stringfield first identified the existence of Floridan Aquifer in peninsular Florida and referred to the carbonate units as the "principal artesian formations." In 1944, M. A. Warren of the Georgia Geological Survey described an extension of this system in south Georgia and applied the term "principal artesian aquifer" to the carbonate units involved. In 1953 and 1966 Stringfield also applied the term "principal artesian aquifer" to these rocks. In 1955, Garald G. Parkernoted the hydrologicand lithologic similarities of the Tertiarycarbonate formations in southeast Florida, concluded that they represented a single hydrologic unit, and named that unit the "Floridan aquifer."
The Floridan aquifer, as opposed to
surficial aquifers, is the portion of the principal artesian aquifer that extends into Florida, parts of southern Alabama, southeastern Georgia, and southern South Carolina. In Florida it supplies the cities of Daytona, Flagler Beach, Gainesville, Jacksonville, Ocala, St. Petersburg, and Tallahassee and numerous rural communities.
The principal artesian aquifer is the largest, oldest, and deepest aquifer in the southeastern U.S. Ranging over 100,000 square miles, it underlies all of Florida and The Floridan portion developed millions of years ago during the late
Paleoceneto early Mioceneperiods, when Florida was underwater. Wakulla Springsin Wakulla County, Florida is one of a number of major outflows of the Floridan with a flow rate of 200-300 million gallons of water a day. A record peak flow from the spring on April 11, 1973was measured at 14,324 gallons (54,226 liters) per second - equal to 1.2 billion gallons (4.542,494) cubic meters) per day.
Groundwater in the Floridan aquifer is contained under pressure by a confining bed of impermeable sediments. When the water pressure is great enough, the groundwater breaks to the surface and a spring flows. Water temperature and flow from a Floridan spring is relatively constant.
In general, as the water flows through the Florida aquifer systems it matures. The water quality becomes more
alkalineand the sulfatecontent increases as does the amount of dissolved solids.cite book
