Wikipedia
Legionella
Legionella is a genus of pathogenic gram-negative bacteria that includes the species L. pneumophila, causing legionellosis (all illnesses caused by Legionella) including a pneumonia-type illness called Legionnaires' disease and a mild flu-like illness called Pontiac fever.Legionella may be visualized with a silver stain or cultured in cysteine-containing media such as buffered charcoal yeast extract agar. It is common in many environments, including soil and aquatic systems, with at least 50 species and 70 serogroups identified. These bacteria, however, are not transmissible from person to person; furthermore, most people exposed to the bacteria do not become ill. Most outbreaks are traced to poorly maintained cooling towers. The side chains of the cell wall carry the bases responsible for the somatic antigen specificity of these organisms. The chemical composition of these side chains both with respect to components and arrangement of the different sugars determines the nature of the somatic or O antigen determinants, which are essential means of serologically classifying many gram-negative bacteria. Legionella acquired its name after an outbreak in 1976 of a then-unknown "mystery disease" sickened 221 people, causing 34 deaths. The outbreak was first noticed among attendees at a convention of the American Legion—an association of U.S. military veterans. The convention occurred in Philadelphia during the U.S. Bicentennial year on July 21–24, 1976. This epidemic among U.S. war veterans, occurring in the same city as—and within days of the 200th anniversary of—the signing of the Declaration of Independence, was widely publicized and caused great concern in the United States. On January 18, 1977, the causative agent was identified as a previously unknown bacterium subsequently named Legionella.

legionella
Legionella is a type of bacterium found naturally in fresh water. When it grows in man-made water systems such as hot tubs, cooling towers, hot water tanks, large plumbing systems, or parts of the air-conditioning systems of large buildings, it can cause a potentially fatal form of pneumonia called Legionnaires’ disease. It can also cause a less severe illness called Pontiac fever. People get infected when they inhale mist or vapor from contaminated water systems. It does not spread from person to person.

Examples of legionella in a Sentence
What we discovered was that when the Flint River water went into the system it released a lot of iron, and removed the disinfectant from the water, and in combination, those two factors, the iron as a nutrient and the disinfectant disappearing, allowed legionella to thrive in buildings where it could not do so previously.
It's difficult to do that -- because you're trying to go back in time. whether anyone does that or not, remains to be seen, what our experiment is going to do is show why the Flint river water was growing more legionella. This is the only way you can do that testing becuase that water doesn't exist anymore, we had to recreate it.

Because Legionella is pretty ubiquitous in the environment, it's not a big stretch to imagine that it would be in the water system, and there were no other exposures that were identified.
