The aims of this study was to understand the differences of L.pneumophila serogroups distribution in well water, tap water, ice cubes, hospital water and hotel water in East Java-Indonesia. A total of 60 water samples were tested by polymerase chain reaction and then it was analyzed by phylogenetic tree. Out of the 60 water samples collected, 12% of the samples were contaminated with L. pneumophila. The phylogenetic tree revealed L.pneumophila contamination in well water from Surabaya and tap water from Sidoarjo and the ice cubes from Sidoarjo, while the bacterial contamination in 2 well water isolate from Surabaya classified into their own group.
