Legionella caused 58% of the 33 outbreaks of drinking-water-related disease reported across 17 states from 2009 to 2010, according to data released by the Centers for Disease Control and Prevention and the Environmental Protection Agency. The bacteria, which causes Legionnaires' disease, was responsible for only 7% of the total 1,040 illnesses linked to drinking water. But Campylobacter caused 78% of the illnesses and 12% of the outbreaks. Most Legionella-related outbreaks were traced to plumbing-system deficiencies, according to the data.
