The inadequacy of protected water supplies in urban centre is a growing problem. In recent years, as communities resort to buy water from vendors, bubble top cans and bottled water became major sources of drinking water in the households and at work. This study is conducted in Chennai city to assess the physiochemical and bacteriological quality of packaged water sold in several key locations of study area. The three main source of packaged water includes bottled water, sachet and Bubble top cans. At the time of study 40 key locations were identified in study area. From each location samples were collected from various vendors and subjected to physical, chemical and bacteriological analysis.
