According to an article in Live Science, Legionnaires’ disease outbreaks through drinking water are rare, but still occurring. In 2009 and 2010, there was a combined 33 disease outbreaks related to drinking water in the US. 1,040 people were associated with these outbreaks including 85 hospitalizations and nine deaths. Four outbreaks were connected to private wells, and the rest were linked to community water.
Over half (58%) of the outbreaks were caused by Legionella bacteria, and 12 percent were caused by Campylobacter. Legionella infected few individuals, however, and was the cause of 7 percent of illnesses; Campylobacter was responsible for 78 percent of cases.
Further, according to an article from Philly.com, the U.S. Environmental Protection Agency stated that bottled water is not necessarily safer than tap water. The EPA is in charge of public water systems while the FDA monitors bottled water; both have standards the water must meet and are safe for consumption if they meet the standards.
