Springs are intricately woven into the fabric of Florida’s history. For thousands of years, humans have been drawn to their crystalline waters, as rich archeological remnants scattered on their banks attest. They W are supplied by the Floridan aquifer, the source of drinking water for much of Florida. Most of Florida’s springs are located in the region stretching from Hillsborough, Orange, Seminole and Volusia counties north and west to Walton County. This manual focuses on this region’s springsheds— the land areas that feed water to the springs. Figure 1.1 Springs are important resources in Florida. 3 s Florida’s population continues to Most Florida springs exist where the grow, our springs are facing increasing Florida’s Geology Creates Our Springs limestone of the Floridan Aquifer is exposed at A pressures. This growth brings an the land surface and ground water is forced out inevitable rise in water use, as well as extensive lorida rests on a bed of limestone. from underground. This type of landscape is land use changes. Water shortages could become Rainwater, made slightly acidic by carbon commonly referred to as “karst.” a controlling factor in the location and timing of F dioxide picked up from the atmosphere, Within this very porous topography, soils new development. Each year, lands within slowly works its way through the limestone, are often sandy.

These development pressures increase. spring. pollutants then emerge in the spring water. Figure 1.2. Karst areas may resemble Swiss cheese when exposed. Figure 1.3. In a karst area, sinks and springs connect ground and surface waters. 4 INTRODUCTION In recognition of the pressures facing Florida’s springs, the Florida Springs The entire state of Florida is a karst region, is near the surface. Comparing Figure 1.4 with Task Force was convened in 1999 to resting on a limestone plateau formed millions of Figure 1.1 reveals the strong correlation recommend strategies for the years ago when the area was a shallow sea. Karst between areas with well-developed karst terrain activity is most visible in those areas where and the location of major springs. protection and restoration of these there is little to no overburden (clay and sandy Springs are classified by their rate of soils) on top of the limestone, and ground water discharge. First magnitude springs produce the fragile resources. Created by Secretary greatest amount of water—100 cubic feet per Figure 1.4.

Eighth magnitude springs where the karst is more developed there is a higher potential for spring development. Environmental Protection, the task force was comprised of sixteen scientists, planners, and other citizens. After meeting for a year, their final report, Florida’s Springs: Strategies for Protection Karst Terrain and Restoration, was issued in Areas with limestone lying at or near the ground November, 2000. It identifies a wide surface with thin overburden; well-developed karst is present.
