The occurrence of Legionella is on the rise and is now the leading cause of waterborne illness in the United States.
Infection occurs through the inhalation of contaminated water vapor primarily found within inadequately maintained
building plumbing systems.
The Centers for Disease Control and Prevention has developed a guide specifically intended for building owners and
managers to reduce the risk of Legionella development.
Developing a Water Management Program to Reduce Legionella Growth and Spread in Buildings
identifies areas or devices in buildings where Legionella may grow or spread to people so that steps can be taken
to reduce this risk.
