New York City Commissioner’s Order
On August 6 2015, the New York City Health Commissioner issued an order to all owners of buildings with cooling towers in response to the Legionnaires Disease Outbreak in the South Bronx. Building owners are now required to register cooling towers, evaporative condensers, and fluid containers with New York State and New York City. See top of page for link to New York City Cooling Tower Registration Portal.
New York City issued this order because of an outbreak of Legionnaires’ Disease in the South Bronx. Several cooling towers in the affected neighborhoods tested positive for legionella. The outbreak has not affected the City’s drinking or bathing water; it is safe for building residents to drink and bathe with tap water. It is also safe to use home air conditioning units and to be in air conditioned areas.
