Legionella

WHAT IS LEGIONELLA?

Legionella bacteria is a waterborne pathogen found in these engineered water systems:

cooling tower
Cooling towers
condensers
Condensers
water heater
Water heaters & storage tanks
filters
Filters
piping
Pipes & valves
ice machines
Ice machines
faucets and valves
Faucets
decorative fountains
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.

Additionally, changes in water pressure, temperature, construction, and inadequate disinfectant can promote Legionella growth.

HEALTH CONCERNS

The presence of Legionella is bad for your mechanical systems. Furthermore, the bacteria becomes harmful when the contaminated droplets are inhaled because it can lead to Legionnaries' Disease.

pneumonia legionella

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
