What should I know about Legionella disease Legionella is the bacteria responsible for Legionnaires Disease, an acute bacterial infection of the lower respiratory tract. This bacterium was first identified in 1. Centers for Disease Control as the cause of an outbreak of pneumonia that caused 3. American Legion Convention in Philadelphia. Pontiac Fever is a less severe, non pneumonia, flu like disease that is associated with and likely caused by Legionella bacteria. Legionella is a fairly common water bacterium and has been found to exist widely in many surface water sources including lakes, rivers, streams and ponds. It can also be found in ground water sources and some soils. At the levels found in these naturally occurring sources it typically does not pose a threat to public health. When the bacterium enters a domestic water system it can find an ideal host environment of warm water temperatures 1. F, stagnant water areas isolated storage tanks and dead end piping legs and ample food sources sediment, scale, deposits and biofilm. Under these conditions Legionella can rapidly colonize, forming higher concentrations that can pose the public health threat of Legionnaires Disease. There are many methods of controlling colonization of Legionella bacteria. However, a widely accepted and preferred method is to maintain the hot water system storage temperature continually at or above 1. F. Unfortunately, the elevated temperature necessary to minimize the growth of and kill Legionella bacteria has the potential to cause serious thermal shock and scalding injuries. As such, many plumbing engineers will specify that the water heater be set to maintain water temperatures at 1. F or higher to reduce the risk of Legionella, but then specify the appropriate mixing valve to ensure safe delivery of hot water to the fixtures.
