Legionella


Legionella

What is Legionella?

 

Legionella is an anaerobic bacteria found naturally in the aquatic environment. It grows best in warm water. It can potentially cause a fatal infectious disease. Its first publically recognized to outbreak was in 1976 in Philadelphia during a Legionnaires Convention where over two dozen deaths were attributed to the bacteria. The incident gave rise to the name of the outbreak – Legionnaires’ Disease. It is also associated with Pontiac Fever, a less harmful illness.

 

Where can it be found?

 

Legionnella has the potential to thrive in warm water contained in (for example) hot tubs, cooling towers (roof-top HVAC systems), hot water tanks, fountains and any other apparatus that holds hot water. There are exceptions: it has not been found to thrive in automobile or window mounted air conditioning systems.

 

Who is at Risk?

 

If present, anyone exposed is at risk to the bacteria contaminated water, water vapour or the air moving over the contaminated water. The bacterium is not transmitted from person to person.

 

Can it be detected?

 

Legionella can be detected, by sampling the water and having it analyzed for the presence of the bacteria.

 

Can we help?

 

Yes, by taking periodic water samples for analyses from hot tubs, roof-top HVAC units, cooling towers, large plumbing systems, hot water tanks or any other equipment where warm water is generated and / or stored. Our work will provide documentation as to the presence of the bacteria and that “due diligence” was given in its investigation.
