The article discusses the water systems in southwest Florida, focusing on the intermediate aquifer system. This system lies between the surface and Floridan aquifers, with varying thickness and transmissivity. In the north, water flows from the intermediate aquifer to recharge the Upper Floridan aquifer, while in the south, the flow direction reverses. In 1985, 808 million gallons of water were withdrawn daily for various uses, with 68.9 million gallons coming from the intermediate aquifer system.
