Legionella bacteria is a waterborne pathogen found in engineered water systems such as:
Cooling towers
Condensers
Water heaters & storage tanks
Filters
Pipes & valves
Ice machines
Faucets
Decorative fountains
A poorly maintained water system can lead to build-up of biofilm, stagnated water and rust. This creates a perfect breeding ground for Legionella bacteria.
Changes in water pressure, temperature, construction, and inadequate disinfectant can promote Legionella growth.
HEALTH CONCERNS
Not only is the presence of Legionella bad for your mechanical systems, but it can endanger your health. Legionella bacteria becomes harmful when contaminated droplets are inhaled. This can lead to Legionnaries' Disease.
Legionnaires' Disease is a severe form of pneumonia. It includes
symptoms such as headaches, muscle pain, fever, and chest pain.
1 in 10 people die from contracting Legionnaires' Disease
Keeping Legionella out of building water systems is key to preventing infection.
How often to test for Legionella?
Testing frequency depends of multiple risk factors. At a minimum:
0 TIMES/YEAR
OFFICES, INDUSTRIAL FACILITIES
0 TIMES/YEAR
HOTELS, APARTMENTS
0 TIMES/YEAR
HOSPITALS, NURSING HOMES
Benefits of regular Legionella testing:
Results allow building operators to target control measures more accurately
Historical lab testing data can help protect owners against potential litigation in the event of an outbreak
Legionella sampling program may reduce insurance premiums
Legionnaires' Disease is on the rise in US and facilities without a testing program will continue to face more scrutiny
Regular testing shows that you value your occupants' safety and health
