Legionella

Legionella is a type of bacteria that naturally exists in freshwater environments like lakes and streams. It can become a health concern when it grows in man-made water systems such as cooling towers, hot tubs, or plumbing, especially if the water is warm and stagnant. People can become ill if they breathe in tiny droplets of water containing the bacteria, leading to Legionnaires’ disease, a severe form of pneumonia. Proper maintenance, cleaning, and disinfection of water systems are essential to prevent its growth and protect public health.
