Samples of water were collected from different sources available at schools and analyzed for physical, aesthetic and bacteriological parameters. The physical analysis included pH, turbidity and electrical conductivity. Aesthetic examination involved colour, odour and taste. In bacteriological analysis total coliforms and feacal coliforms (E. coli) along with their relationship with residual chlorine were determined. An awareness study regarding water problems was conducted involving one hundred teachers and students in the schools using a questionnaire. Most of the water samples taken from schools were fit for drinking, as far as physical and aesthetic water quality parameters were concerned except ground water. Ground water available in some of schools was saltish and brackish and was unfit for human consumption. WASA water as direct supply contained sufficient amount of chlorine and did not have any bacteria. Most of the water samples that w ere taken from coolers and storage tanks of schools had no chlorine content and contained coliforms. Feacal coliforms (E. coli) were not present in any of the samples tested in the study.
