Water filters are being installed at three more buildings at the Melrose Houses in the Bronx after tests came back positive for the bacteria that causes Legionnaires' Disease.
Earlier this week, filters were installed at 681 Cortlandt Avenue after four cases of the disease had been reported in the complex.
The bacteria was found in the hot water system, and residents in the affected buildings will have to go without hot water until the upgrades by the city's housing authority are finished.
Officials say the water is safe to drink, but they don't want to risk having people breathing in infected steam, which is how Legionnaires' is spread. Preliminary tests came back negative for the other five buildings of the complex.
