In any water system, especially in large buildings such as hospitals, hotels, and office complexes, maintaining water quality is critical for preventing the growth of harmful bacteria like Legionella. Legionella, the bacterium responsible for Legionnaires' disease, can proliferate in poorly maintained water systems, posing serious health risks. To combat this, businesses and property managers need to implement Legionella risk management services —specialized programs designed to monitor and control Legionella bacteria in water systems.

While most healthy individuals are at low risk,...
