- The optimal temperature range for Legionella growth is 77-108℉.
- Legionella grows best in large, complex water systems that are not adequately maintained.
- Fluctuating temperatures and stagnated water in plumbing systems also contribute to Legionella
- Improperly maintained plumbing systems can lead to sediment, scale, and corrosion, all of which provide a habitat and nutrients for Legionella
- Legionella can grow on a biofilm, which is a group of microorganisms, such as bacteria, that can attach to the interior surface of plumbing lines, providing a protective barrier for the Legionella
