Under certain environmental conditions, any water system could become a source for Legionella bacteria. Legionella bacteria are common in lakes, ponds and rivers; however outbreaks of Legionnaires’ disease rarely originate from these sources. Outbreaks of the illness occur from exposure to Legionella growing in purpose-built systems such as: cooling towers, hot and cold water systems, and spa pools. Water in these systems is maintained at a temperature high enough to encourage growth. Humidifiers, air washers, emergency showers, and ornamental fountains also pose a risk for Legionella bacteria growth.
