“Legionnaires’ disease and Pontiac Fever are collectively known as Legionellosis, a disease caused by Legionella bacteria. Managing Legionella and preventing worker exposures and Legionellosis cases depend on implementing an effective water management program. These programs focus on describing water systems and their components, identifying areas where Legionella could grow, deciding where control measures are needed and how to monitor them, planning response actions when control measures fail, and monitoring and documenting water management activities.”.
