These outbreaks resulted in 1,006 cases of illness, 124 hospitalizations and 13 deaths. Additionally, 57% were found to be caused by legionella. The study concluded that 75% of the 1,006 cases of illness were related to community water systems regulated by the government.

The second study showed similar resulted examining 12 outbreaks across Alabama, California, Kentucky, Montana, New York, Ohio, Pennsylvania and Texas in the same time frame.
