A New York City Department of Health Representative said the following: “We are looking specifically at the hot water supply since Legionella likes to grow in hot water environments.

At least a dozen Hamilton residents have died from Legionnaires’ disease since 2018, public records show (Not all cases have been definitively linked to Trenton Water Works).ByJeff Pillets

At least 12 residents of one suburban Mercer County community have died over the past half-decade from Legionnaires’ disease, a form of pneumonia caused by bacteria that can thrive in stagnant tap water.

The deaths in Hamilton Township, a bedroom community of 92,000 people, were enumerated Tuesday in data released by township health officials in response to a public information request by a local blogger.

The data, which was shared with The Jersey Vindicator, shows that the impact of waterborne illness in towns served by the troubled Trenton Water Works could be much higher than was widely understood by the public.
