Hot water back on for some in Bronx complex where Legionella bacteria discovered

MELROSE (WABC) -- Hot water is now back on for some residents of an apartment complex in the Bronx where the bacteria that causes Legionnaires' Disease was discovered last week.

On Saturday, the city housing authority installed ionization systems to treat the water at the Melrose Houses.

The system releases ions, which are harmless to people, but kill the Legionella Bacteria.
