Four brands of sachet packaged water samples were collected in and around Ramnad and Sivagangai district, People use polluted water which causes many health problems and therefore people must be edu cated to remove impurities from water. The present study was carried out to determine the physico-chemical quality of 4 brands of packaged drinking water available at two different regions and compared with Bureau of Indian Standards Specifications (BIS). The results of the analyses revealed that most of the water samples were colourless, odourless. The chemical analysis showed that the measured parameters are in the range: pH (8.3-9.1); electrical conductance - EC (0.11-1.1 unit); alkalinity (0.6-1.0 mg/l); total hardness - TH (18.5-35.0 mg/l); calcium hardness (20.0-23.75 mg/l); magnesium hardness (3.5-11.75 mg/l); dissolved oxygen - DO (5.2-9.2 mg/l); chemical oxygen demand - COD (0.25-0.38 mg/l); chloride as Cl- (15.9-24.25 mg/l); sulphate (20.63-27.5 mg/l). It can be noticed that the concentration of the investigated parameters in the analysed water samples were within the permissible limits of the bureau of Indian standard (BIS) drinking water quality guidelines except for the values of pH and DO. The pH values for sample B, C and D which is also above the permissible limits as prescribed by BIS
