ABSTRACT: Bacteriological analysis was undertaken on 90 samples of water from primary, secondary and high schools in 10 townships of Yangon area. Most of the schools (8.81% of primary; 55.56% secondary & 70% high schools) have artesian wells. It was also found that 18.18%, 33.33% and 30% of primary, secondary and high schools respectively received water supply from Yangon City Development Committee (YCDC). In this study, only one secondary school used water from hand dug well; one high school had stainless steel tank; some schools had aluminium tanks and some had concrete brick storage containers. Purified water bottles with different brand were used for drinking water in most of the schools. From drinking water sources, coliforms were identified from purified water (66.67%), YCDC water (100%), artesian water (82.35%). Alhough faecal coliforms were not identified from purified water, they were isolated from YCDC water sources (83.33%), and artesian water (64.71%) which were used as drinking water. For domestic water source, coliforms and faecal coliforms were identified from YCDC water (100% & 87.50%) and artesian water (70% & 45%) respectively. From water used as sanitary purposes, coliforms and faecal coliforms were identified from YCDC water (100% & 62.50%) and artesian water (95% & 70%) respectively.
