    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 grew out of the investigation of a series of pneumonia cases. Legionella bacteria is found naturally in freshwater, such as ponds and streams that evaporate. 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.

The company’s focus is on water safety and providing customers with results they can rely upon.
