Florida’s subsurface rocks lie fairly flat, while the rocks in the northern and western United States have been intensely folded over millions of years to produce very complex geology. Florida is comprised of three main aquifers: the surficial Floridan aquifer system aquifer, which is broken down into the sand and gravel aquifer and the Biscayne aquifer, the intermediate aquifer, and the huge, statewide Floridan aquifer. Confining layers vary throughout the state. In some areas, the confining layers are absent to very thin, while in other areas, they can be almost 200 feet thick. Water Resources Atlas of Florida, Institute of Science and Public Affairs Above: Geologic map of Florida Map-Florida Geological Survey All of Florida is underlain by thick sequences of limestone and dolostone. In most parts of the state, these rocks are covered with layers of sand. Together, the sand and carbonate rocks form an enormous groundwater reservoir, providing more groundwater than any other state: more than a quadrillion gallons!

  • Biscayne Aquifer, Florida Groundwater Provides Nearly 50 Percent of the Nation’S Drinking Water
    National Water Quality Program National Water-Quality Assessment Project Groundwater Quality in the Biscayne Aquifer, Florida Groundwater provides nearly 50 percent of the Nation’s drinking water. To help protect this vital resource, the U.S. Geological Survey - (USGS) National Water-Quality Assessment (NAWQA) Project assesses groundwater quality in aquifers that are important sources of drinking water (Burow and Belitz, 2014). The Biscayne aquifer constitutes one of the important aquifers being evaluated. Background Overview of Water Quality The Biscayne aquifer underlies an area of about 4,000 square miles in southeastern Florida. About 4 million people live in this area, and the Biscayne aquifer is the primary source of drinking water with about 700 million gallons per day (Mgal/d) withdrawn for public supply in 2000 Inorganic Organic (Maupin and Barber, 2005; Arnold and others, 2020a). The study area for the Biscayne aquifer constituents constituents underlies much of Broward and Miami-Dade Counties in southeastern Florida and includes 3 the cities of Miami and Fort Lauderdale. Most of the area overlying the aquifer is developed 5 and consists of about 63 percent urban and 9 percent agricultural land use. The remaining area 17 (28 percent) is undeveloped (Homer and others, 2015). The Biscayne aquifer is an unconfined, surficial aquifer made up of shallow, highly 80 95 permeable limestone as well as some sandstone units (Miller, 1990). Because of the shallow depth of the units that make up this aquifer, the connection to surface water is an important aspect of the hydrogeology of the Biscayne aquifer (Miller, 1990). A system of canals and levees are used to manage the freshwater resources of southern Florida.

  • West-Central Florida's Aquifers: Florida's Great Unseen Water Resources
    West-Central Florida's aquifers: Florida's great unseen water resources Item Type monograph Publisher Southwest Florida Water Management District Download date 27/09/2021 20:30:45 Link to Item http://hdl.handle.net/1834/19407 Southwest Florida Water Management District West-Central Florida’s Aquifers Florida’s Great Unseen Water Resources Th e abundance of Florida’s freshwater resources provides a great attraction for residents and tourists alike. Th e rivers, lakes and wetland areas found throughout the state serve as a water-lover’s paradise for fi shing, boating, hiking and many other recreational activities. However, the majority of Florida’s fresh water is inaccessible to the public for recreational purposes. In fact, most of the state’s fresh water lies underground in Florida’s aquifers. While the ground water within Florida’s aquifers remains unseen, it still serves a vital role in maintaining the quality of life for all Floridians. Th e District is responsible for protecting this important resource. A cave diver explores the Upper Floridan aquifer through a spring. What Is an Aquifer? An aquifer is a layer of underground rock or sand that stores water. Th e ground water within an aquifer can fi ll the spaces between grains of sand and gravel, or it can fi ll the cracks and fi ssures in solid rock. Th e water within an aquifer is constantly moving. How quickly the water moves depends on both the physical characteristics of the aquifer and the water-level gradient, or slope, in the aquifer. In aquifers with large caverns or many large fractures, water can travel very quickly.

    Professional Paper SJ95-PP3 PREDICTING AREAS OF FUTURE PUBLIC WATER SUPPLY PROBLEMS: A GEOGRAPHIC INFORMATION SYSTEM APPROACH by Paula Fischl St. Johns River Water Management District Palatka, Florida 1995 Northwest Florida Water Management District Suwannee River Water Management District St River Water St. Johns Rlv Water Management District Florida Water Management District South Florida Water Management District The St. Johns River Water Management District (SJRWMD) was created by the Florida Legislature in 1972 to be one of five water management districts in Florida. It includes all or part of 19 counties in northeast Florida. The mission of SJRWMD is to manage water resources to ensure their continued availability while maximizing environmental and economic benefits. It accomplishes its mission through regulation; applied research; assistance to federal, state, and local governments; operation and maintenance of water control works; and land acquisition and management. Professional papers are published to disseminate information collected by SJRWMD in pursuit of its mission.

Box 1429 Palatka, FL 32178-1429 Phone: (904) 329-4132 ABSTRACT: A geographic information system methodology was developed to ensure the adequate placement of the locations of current ground water flow models used by the St. Johns River Water Management District and to delineate areas where new analyses should be performed. This methodology uses an overlay procedure with gridded surfaces to identify areas that have a high potential for (1) impacts to wetland vegetation, (2) saltwater intrusion, and/or (3) an increase in public water supply demand.

  • USGS Issues Revised Framework for Hydrogeology of Floridan Aquifer Released: 4/21/2015 9:58:48 AM
    Technical Announcement: USGS Issues Revised Framework for Hydrogeology of Floridan Aquifer Released: 4/21/2015 9:58:48 AM Contact Information: Jon Campbell U.S. Department of the Interior, U.S. Phone: 703-648-4180 Geological Survey Office of Communications and Eve Kuniansky Publishing Phone: 678-924-6621 12201 Sunrise Valley Dr, MS 119 Reston, VA 20192 USGS scientists have updated the hydrogeologic framework for the Floridan aquifer system that underlies Florida and parts of Georgia, Alabama, and South Carolina. The Floridan aquifer system is the principal source of freshwater for agricultural irrigation, industrial, mining, commercial, and public supply in Florida and southeast Georgia. The extensive underground reservoir currently supplies drinking water to about 10 million people residing across the area as well as 50% of the water that is used for agricultural irrigation in the region. By describing the hydrologic and geologic setting of an aquifer, a hydrogeologic framework enables appropriate authorities and resource managers to monitor an aquifer more accurately, improving their ability to protect these critical resources and determine the near- and long-term availability of groundwater. As the first update of the framework for the aquifer in over 30 years, the revision incorporates new borehole data into a detailed conceptual model that describes the major and minor units and zones of the system. Its increased accuracy is made possible by data collected in the intervening years by the USGS; the Geological Surveys of Alabama, Florida, Georgia, and South Carolina; the South Florida, Southwest Florida, St Johns River, Suwannee River, and Northwest Florida Water Management Districts; and numerous other state and local agencies.
