Legionella Risk Factor: Temperature

One of the primary risk factors for Legionella growth is the temperature of the water. Typical healthcare, hotel, warehouse, and other facility water systems contain water that falls into the range of Legionella growth. Peak levels of growth are found in a specific range that is common in water systems during warmer months.
