“Legionella is common in many water supply sources. Under certain conditions, such as stagnant water environments, these bacteria can thrive in biofilm, scale, and sediment within the building”. “Yes, the municipal water supply is chlorinated, but this type of bacteria survives by living in certain amoeba, ciliated protozoa, or biofilm, allowing it to multiply and appear in finished water supplies.”
Since it is an endosymbiont living symbiotically in another organism, Legionella likely already existed in the pipes. Although trace amounts rarely result in the disease, when certain Legionella are allowed to propagate and transmit to a susceptible human host, they can cause legionellosis infections.
Merely flushing the system by letting the water run for a while is not an option since the bacteria live in biofilm.

Legionella acquired its name after an outbreak of a then-unknown “mystery disease” sickened 221 persons, causing 34 deaths. The outbreak was first noticed among people attending a convention of the American Legion—an association of U.S. militaryveterans. The convention occurred in Philadelphiaduring the U.S. Bicentennial year in 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.
