Groundwater Overdraft and Its Impact on Florida's Everglades and Karst Landscapes

This paper examines the implications of groundwater overdraft in Florida, particularly concerning its impact on the Everglades. It discusses confined aquifers and the potentiometric surface, highlighting how hydrostatic pressure influences water levels. The phenomenon of overdraft in karst landscapes leads to subsidence and structural collapse, exposing vulnerabilities such as sinkholes. Additionally, it explores the rapid migration of contaminants within subterranean conduits, emphasizing the risks of polluted surface waters infiltrating groundwater systems.
