Bayamon, Puerto Rico, January 6th, 2020 -- There were a number of outbreaks of Legionnaires’ disease across the United States last year that are believed to have been linked to water systems in apartment buildings. People can develop this potentially fatal disease when they breathe in Legionella bacteria that has been aerosolized in small droplets of water.


The Centers for Disease Control and Prevention (CDC) reports that many buildings need a water management program to reduce the risk of Legionella growing and spreading within their water system and devices. The agency goes on to state that Legionella can grow in many parts of building water systems that are continually wet, and certain devices can then spread contaminated water droplets. Examples include:

Hot and cold water storage tanks
Water heaters
Water-hammer arrestors
Expansion tanks
Water filters
Electronic and manual faucets*
Faucet flow restrictors
Showerheads* and hoses
Pipes, valves, and fittings
Centrally-installed misters*, atomizers*, air washers* and humidifiers*
Nonsteam aerosol-generating humidifiers*
Infrequently used equipment, including eyewash stations*
Ice machines*
Hot tubs*
Decorative fountains*
Cooling towers*
Medical devices* (such as CPAP machines, hydrotherapy equipment, bronchoscopes)
*These devices can spread Legionella through aerosols or aspiration


“Apartment buildings and condo complexes have many of the risk factors listed by the CDC and should have a water management program to reduce the risk of Legionnaires’ disease for residents, workers and other building occupants,” said Harry Pena, President of Zimmetry Environmental. “This is especially true in places with people 50 years or older, current or former smokers, and with people with chronic lung disease or a weakened immune system because these populations are considered to be at increased risk of getting this infection.”
