HI 96725


          Legionella species is the agent that causes human Legionnaires’ disease as well as the lesser form, Pontiac Fever. Transmission is facilitated by the inhalation of mist droplets containing the Legionella bacteria. Common sources of Legionella include cooling towers used in industrial cooling water systems as well as in large central air conditioning systems, domestic hot water systems, fountains, and similar disseminators that draw from a public water supply. Natural sources include freshwater ponds and creeks. Since Legionella is especially harmful to people with weakened immune systems, Legionella should be actively checked for in the water systems of hospitals and nursing homes. The HI 96725 measures 4 parameters that are crucial in monitoring for preventive maintenance or disinfection.
