Two confirmed cases of Legionnaires' disease have turned up at a Queens housing complex, and the city's health department is now investigating the building's water systems to find the source.
This is a second, distinct Legionnaires' cluster from the one already circulating this week — different building, different confirmed case count, and it is still in the investigation phase rather than the remediation phase. The city's playbook is the same either way: find every cooling tower and water system tied to the address, test them, and treat or shut down whatever comes back positive.
For a contractor, the relevant fact is what happens next, not the diagnosis. Local Law 77 requires registered cooling towers to be inspected, tested, and have their results filed with DOB on a schedule; a confirmed Legionnaires' case anywhere near a building pulls every cooling tower within roughly a quarter-mile into an inspection sweep, whether or not that tower was due for one. If you maintain, service, or are mid-retrofit on a cooling tower in Queens, expect your client's super or management company to be fielding a DOB or DOHMH inquiry this week, and expect a compliance filing to move up your punch list.
The city's own cooling tower registry and the DOHMH Legionnaires' disease dashboard are the places to check whether a specific address is on notice — both update as cases are confirmed. First reported by Gothamist.
What to do now: if you have a maintenance contract on a cooling tower anywhere in Queens, pull your most recent Local Law 77 test results and confirm they're filed with DOB before an inspector asks. There's no posted deadline on this specific investigation yet, but DOHMH moves fast once a cluster is confirmed — treat this week as the window to get your paperwork current, not next week.
