At what water temperature does Legionella bacteria thrive, which poses a risk in pools?

Legionella bacteria thrive at water temperatures between 77 and 113 degrees Fahrenheit. This is significant because these temperatures create an ideal condition for the bacteria to grow and multiply. They are often found in warm water environments such as hot tubs, fountains, and pools. Maintaining water temperatures outside this range is crucial in preventing the proliferation of Legionella, which can lead to serious health issues such as Legionnaires' disease when inhaled through aerosolized water droplets.

Understanding the temperature range in which Legionella is most active is essential for pool maintenance and ensuring the safety of swimmers. Proper monitoring and control of water temperatures, along with regular maintenance practices, can help mitigate the risks associated with this type of bacteria.
