According to news reports, at least four people were diagnosed with Legionnaires’ disease after staying at The Osthoff Resort in Elkhart Lake, Wisconsin. Legionella bacteria, which causes Legionnaires’ disease, was found in the men’s restroom near an indoor pool and in a cooling tower at the resort. Cooling towers continue to play an important role as to how persons contract Legionnaires’ disease, including numerous clients of this firm currently being represented. Cooling towers are a source of infestation because of how they are designed and operate. The warm air from inside the building is cooled by coming into contact with cool water in the tower. Biofilm, or sludge, builds up over time which contains the legionella bacteria. The mist resulting from the interaction of the warm building air with the cool water in the tower then picks up bacteria from the biofilm and transmits it int the air. The mist containing the potentially deadly legionella bacteria then is inhaled by an unsuspecting pedestrian or occupant of the building with the cooling tower. Cooling towers need to be regularly treated and not just inspected to prevent this catastrophe from happening.
