Legionnaires' disease is a serious health problem.
Put very briefly, Legionnaires's disease is a very controllable air/water borne health issue that can be controlled with proper maintenance. Unfortunately, it took a vicious and fatal outbreak of this serious disease for the health authorities to take notice and do something about it.
Inhaling the water vapor or mist containing or infected with legionella can result in serious health issues such as pneumonia and worse.

For several years ParPools.com has been trumpeting the need to control, treat and remove biofilms from swimming pools and hot tubs. Legionnaire's disease grows (can grow) readily in untreated and poorly maintained water containment vessels (primarily water towers or air conditioning coolers).
