A deadly Legionnaires’ disease outbreak on Manhattan’s Upper East Side has resulted in 94 confirmed cases and 11 deaths, renewing serious questions about cooling tower testing, maintenance, enforcement and public-health oversight. New York City officials and City Council members are now considering additional measures aimed at preventing future outbreaks, including stronger testing requirements, increased enforcement, greater transparency and efforts to locate cooling towers operating without proper registration. The developments raise an important question for building owners and facility managers everywhere: Are current cooling tower monitoring and maintenance requirements enough to prevent Legionella outbreaks before people become sick?
