That number is more than double the 31 cooling towers previously reported last week.
Officials say 57 are confirmed to have completed the required remediation and the remaining 19 are required to complete the remediation process by Thursday.
Among the list of affected buildings is the Metropolitan Museum of Art located at 1000 Fifth Ave. It is one of the 19 locations still need to complete the remediation process.
"We have been notified by the Department of Health that testing detected a trace amount of Legionella bacteria in our cooling tower system," the Met said in a statement. "In accordance with New York City guidelines and our established health and safety protocols, we have immediately initiated the required remediation and are working with the City and our third-party water management specialists to conduct follow-up testing."
The museum said that based on the guidance from the city and public health experts, the "finding does not pose a risk to staff or visitors inside the Museum."
The Met is another museum on the Upper East Side that has tested positive for Legionella bacteria -- another popular museum being the Guggenheim at 1071 Fifth Ave.
Some of the impacted locations include three private schools, a rehabilitation and nursing center and a church.

Of the 183 cooling towers in the area that were sampled, there are no other outstanding tests waiting for results.
Officials have noted that while cooling towers may test positive for Legionella bacteria, additional testing is needed to determine whether a specific tower is connected to the outbreak.
Latest number of confirmed cases
The outbreak has sickened 63 people as of Tuesday night, up three from the night before. However, hospitalizations decreased from 15 to 12. Cases have been reported across several neighborhoods, including Carnegie Hill, Yorkville and Lenox Hill.
Officials say they are now seeing significantly fewer cases and more than half of all patients who were hospitalized have returned home.
City Council Speaker Julie Menin was encouraged by the development, but fired another shot at Mayor Zohran Mamdani and the health department.
"From day one I've said the health department should be proactively ordering the disinfecting of all towers rather than waiting for test results to come back where more and more people end up contracting Legionnaires'," Menin said.
Dr. Tyler Evans, CEO of Wellness Equity Alliance, is a former New York City chief medical officer during the COVID-19 pandemic. He says proactively disinfecting all cooling towers just isn't realistic.
"Particularly under this current administration where public health is really under attack from a federal level, where a number of cities, counties and states are losing funding, losing support, losing legitimacy, it is increasingly more difficult for us to do our jobs," Evans said.
Councilmember Lynn Schulman says a lack of resources is also the reason why the health department hasn't been enforcing a new law that mandates buildings to proactively test cooling towers every 31 days during the summer months, despite a significant number of non-compliant buildings.
She says the department of health is focused instead on the current outbreak.
"When we passed the bill the previous administration thought it was a good idea," Schulman said. "This DOHMH thinks it's a great bill and we just need to make sure it gets enforced."
Evans pointed out how unique this outbreak is because almost every other legionella outbreak in the past 40 years has been in underserved Black and brown communities in Harlem and the Bronx.
The hope is since buildings on the Upper East Side have more resources, they will be able to sanitize towers more quickly.
Health officials are urging anyone experiencing pneumonia-like symptoms to seek medical attention.
