One of the most pressing issues that we face today is the phenomenon of red tide. Red tide is algae bloom that can cause serious harm to marine life and humans.

In this article, I will explore what red tide is, what causes it, and its impact on Florida. Most importantly, the role of wastewater treatment in helping to prevent it.

What is Red Tide?

Red tide is a natural phenomenon that occurs when certain species of algae grow out of control. These algae produce toxins that harm marine life and humans. The term "red tide" comes from the reddish-brown color that the water takes on when the algae bloom. The bloom can happen in any part of the world in warm, coastal waters.

What Causes Red Tide? 

Various factors cause these harmful algae to bloom.

• Changes in water temperature
• Nutrient pollution
• Ocean currents

The most common cause is nutrient pollution. Nutrient pollution occurs when excess nutrients like nitrogen and phosphorus enter the water. These nutrients can come from agricultural runoff, sewage from residential drain fields, inefficient wastewater treatment plants, septic tanks, and fertilizer.

Red Tide Blooms in Florida - History and Impact

Florida has a long history of deadly algae blooms. The state experiences red tide almost every year, lasting for months.

It devastates the state's marine life, including fish, sea turtles, and dolphins. The algae produce toxins that can kill these animals. The dead fish can wash up on shore, causing beachgoers an unpleasant odor and an eyesore.
