“King tide” is a popular non-scientific term that people use to describe very high tides, that can cause nuisance flooding on sunny, blue-sky days in low lying areas.
They occur a few times per year, typically during a new or full moon and when the moon is closest to Earth. The combination of warm waters off the coast of Florida and the slowing down of the Gulf Stream creates a favorable environment for king tides to occur during the fall season.

The Biscayne Bay Aquifer is of the primary source of drinking water for South Florida.
Located just below the land surface it is composed of a porous rock with small cracks and holes through which rainwater seeps and fills. The water is collected into on-site and remote wells where it begins its water treatment process. The water is softened, settled in contact basins, passes through a primary and secondary disinfection, filtered for sand and anthracite, phosphorous is added to reduce corrosion, finally water is stored in reservoirs and remote tanks where the water is ready to use.
Sea level rise is possessing as a large threat to South Florida’s drinking water. With the sea level projected to rise between 3 and 7 inches by 2030, and 9 to 24 inches by 2060. This increase causes saltwater intrusion to the Biscayne Bay Aquifer, which is described as “movement of saline water into freshwater aquifers”. This process leads to contamination of drinking water which leads to a reducing on our already stressed water supply.
