Artesian water from the underground - Floridan aquifer, USA

  
  
The Floridan Aquifer is a portion of the principal artesian aquifer that extends into Florida and is composed of carbonate rock and located beneath the coastal regions of the Southeastern United States and is one of the world's most productive aquifers. It is under all of Florida as well as large parts of coastal Georgia and areas of coastal Alabama and South Carolina.
The principal artesian aquifer is the largest, oldest, and deepest aquifer in the southeastern U.S. Ranging over 100,000 square miles (260,000 km2), it underlies all of Florida and The Floridan portion developed millions of years ago during the late Paleocene to early Miocene periods, when Florida was underwater.
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 alkaline and the sulfate content increases as does the amount of dissolved solids. (Source: Wikipedia)

Freshwater Ecoregion of the World : #156 Florida Peninsula
Major Habitat Type: tropical and subtropical coastal rivers
Freshwater habitats: This ecoregion is characterized by a variety of aquatic habitats that is virtually unequaled elsewhere in North America. Though intermittent streams are few, there are abundant marshes, swamps, mangrove swamps, ponds and lakes, springs, and large rivers. In fact, Florida in total has more artesian springs than any other region of the world, with one hundred major springs occurring beside or within the channels of the Suwannee River or its main tributaries alone (Carr 1994). The lower reaches of all the rivers that flow into the Atlantic or Gulf of Mexico experience the effects of tides and are often inhabited by both euryhaline (salt-tolerant) freshwater and marine species, including tropical peripheral species (Gilbert 1992).
