Legionella is a form of pneumonia which can be contracted by inhaling small drops of water suspended in air which contain legionella bacteria.

Any water system with the right environmental conditions could be a source for legionella bacteria growth. The most common sources of legionella are in man-made water systems, including hot and cold water systems.
