Legionellosis is a water-borne disease caused by the bacteria Legionella pneumophila. The bacterium can cause severe pneumonia that could be fatal in 5% of patients. Legionnaires’ Disease was first identified after an outbreak at the American Legion convention in Philadelphia in 1976 and grew out of the investigation of a series of pneumonia cases. Legionella bacteria is found naturally in freshwater, such as ponds and evaporating streams. However, human activities can speed up its growth by providing conditions for the bacterium to flourish. This includes cooling towers, air conditioning systems, and hot water tanks.

EMSL Analytical, Inc.’s legionella testing laboratories programs include a comprehensive testing service that provides customers with results they can rely upon. For anyone who needs to determine the levels of bacteria and other contaminants in their supply water or still waters, we will provide you with an accurate report for your specific requirements.
