Legionella, the bacterium that causes Legionnaires’ disease, occurs naturally in freshwater environments, like lakes and streams. Generally, the low amounts of these bacteria in freshwater do not lead to disease.

However, Legionella can pose a health risk when it gets into building water systems. To do this, Legionella first has to grow (increase in numbers). Then it has to spread through small water droplets (aerosolization) that people can breathe in.

Factors That Lead to Legionella Growth

Legionella can live and grow in biofilm.

A variety of internal and external factors can lead to a Legionella problem in your building, including:

· Construction

· Water main breaks

· Changes in municipal water quality

· Biofilm

· Scale and sediment

· Water temperature fluctuations

· pH fluctuations

· Inadequate levels of disinfectant

· Changes in water pressure

· Water stagnation
