How many types of aquifers does Florida have?
There are two types of aquifers in Florida, Surficial and Floridan. Surficial aquifers are made up of shallow bed of sand and shells. They lie above the Floridan aquifers and are separated by a confining bed of soil. These aquifers are recharged from the water flow from the surrounding areas, thus, can be contaminated easily. Their recharge depends largely on the climatic fluctuations. Floridan aquifers are a part of principal artesian aquifer, which is the largest, deepest and oldest of all the aquifers in the nation. Groundwater in the Floridan aquifer is held under pressure by a confining bed of impermeable sediments. Increase in water pressure results in flowing of water to the surface and springs. Biscayne aquifer, Sand and Gravel aquifer, and Chokoloskee Aquifers are all part of the Floridan aquifer.
