This project will investigate the recharging of excess surface water, treated to primary drinking water standards, into the Upper Floridan aquifer more than 1,000 feet below the land’s surface. The recharged water has the potential to help improve groundwater levels and reduce the rate of saltwater intrusion from the Gulf of America in the SWUCA’s Most Impacted Area.SWUCA Recovery and Natural System ImprovementIn 2017, the District conducted a feasibility study at…

The Peace River gets its fresh water from rainfall. Annual rainfall averages approximately 53 inches, with more than half occurring between June and September. Most of the rainwater reenters the atmosphere through evaporation and plant transpiration. The rest recharges the aquifer or runs off into the Peace River and its tributary streams. The river is primarily a blackwater river. This type of river drains pine flatwoods and cypress swamps and has dark, stained waters…

A watershed is an area of land that water flows across as it moves toward a common body of water, such as a stream, river, lake or coast.The majority of people in this watershed live within 10 miles from the Gulf of America. This means that many of the activities that take place in the watershed where people live — from maintaining attractive landscapes to creating new roads and buildings — directly impact the gulf and every water body leading up to it. The Southern…
