What is Legionnaires' Disease?


According to the CDC, it is "a serious type of pneumonia (lung infection) caused by Legionella bacteria. Pulled from the latest surveillance report from 2016-2017, a total of 63,529 cases have been confirmed between 2000-2017.


"In man-made settings, Legionella can grow if water is not properly maintained. These manmade water sources become a health problem when small droplets of water that contain the bacteria get into the air and people breathe them in. "

Of these cases, 9 in 10 are preventable with proper building water treatment management. One of the most common sources of which are cooling towers.
