Legionella Control and Water Treatment in Commercial Buildings

(7 Credits)

Three major outbreaks of Legionnaires’ disease occurred in New York City in 2015. Each outbreak was linked to contaminated cooling tower(s) operating on rooftops of buildings within the outbreak zone. This public health threat prompted the promulgation of emergency regulations to clean and disinfect every cooling tower in New York City and New York State. In this seminar, gain an overview of Legionella issues in buildings. Examine the components of a comprehensive water treatment program to control microbiologic and chemical fouling of cooling towers and other heat transfer equipment in typical commercial office buildings.
