Description

Ginger Ale Springs is a fifth-magnitude spring. The main pool of Ginger Ale Springs is enclosed within a 3.5-foot-high concrete, circular wall about 12 feet in diameter. A large sand boil is visible approximately 3 feet to 4 feet below the water's surface, with several more sand boils also visible. Seven mature palm trees surround the concrete pool. The pool discharges out of a rectangular opening in the side of the wall, then flows northwest in the sandy spring run about 550 feet long and 3 feet wide to the Little Wekiva River. Another vent is located on the west bank of the Little Wekiva River, with numerous other small sand boils in the river floodplain on the west side of the river.

Age of discharge water

The age of water discharging from Ginger Ale Springs was determined by measuring the concentration of tritium, delta carbon-13, and carbon-14 in the spring discharge, which was measured in March 2005. Ginger Ale Springs had a tritium concentration of 0.16 tritium units, which suggests that the water is about 75 years old. Ginger Ale Springs had a delta carbon-13 value of −9.71 parts per thousand and a carbon-14 concentration of 23% modern carbon, which results from the reaction of rainfall with calcite, dolomite, and soil organic matter. The Fontes and Garnier (1979) carbon-14 age of Ginger Ale Springs is 4,334 years old.
