Posted By Graham Findlay If anyone out there has had experience in managing legionella in schools, I would greatly appreciate your assistance. I'm aware that for legionella bacteria to thrive, conditions such as water temperatures, design of the water system, and the ability to inhale contaminated water as an aerosol must exist. Also, certain groups of people are more at risk from developing Legionnaire's disease, and healthy children are only rarely affected. Has anyone got any knowledge regarding legionella risk assessment and, maintenance and monitoring that they could pass on? Many thanks
