Facilities Management
City College is committed to ensuring the health and safety of our campus community. As part of our routine cooling tower maintenance program, a water sample collected on July 26, 2025 from the cooling tower located at the Marshak Building, tested positive for the presence of Legionella bacteria and we were informed of the positive result on August 8, 2025.
Upon receiving the test results, the cooling tower system was cleaned and disinfected on August 9 in accordance with New York City Department of Health and Mental Hygiene (NYC DOHMH) regulations and industry best practices.
Follow-up sampling will be collected 3 to 5 days after disinfection as required by testing protocol and the result of the samples are expected 10 to 12 days after collection. We will share updates once the additional test results are available.
The College will continue to follow all regulatory requirements and preventive maintenance protocols to ensure the ongoing safety of our facilities.
