Mitigating the Risk of Legionella in Building Water Systems

One of the very interesting sessions at the ABPA Conference in Orlando this year was the threat of the Legionella bacteria in our water systems, and how to mitigate the threat. Watts has produced a document that can be found at that explains Legionella and Legionnaires’ Disease (LD) in detail and how to mitigate it.

Outbreaks of Legionella bacteria can cause Legionnaires’ Disease (LD) in any setting, but is a particular concern in healthcare facilities (hospitals, nursing homes, long term care) and hospitality buildings (hotels, motels, resorts). The bacteria can grow in any part of a water system in a building that is continually wet such as tanks, piping, fixtures, or water features. The Legionella bacteria becomes an infectant when combined with water droplets that become airborne in a manner of aerosol generation, and that moisture reaches a person’s nose or mouth where it is inhaled and settles in the lungs.
