Increasing saltwater intrusion along South Florida’s coast has led to degradation, specifically in the Everglades. This encroachment continues to contaminate other natural resources, mainly natural aquifers and coastal wells. 

Wastewater treatment facilities are also threatened, enduring frequent flooding during storm surges and spring tides. The increase in high-tide flooding events accelerates the rate of sea level rise. In the last decade, the standard rate rose to 6 milimeters per year.
