Assessment of Physicochemical and Biological properties and effect of temperature On bottled water of Different Brands in Lahore City

Drinking water quality is declining frequently. The poor quality of drinking water has enforced to purchase bottled water. Many mineral water companies were found selling low quality water. Hence, main purpose of research was to perform a comparative analysis of Multinational, National and local bottled water companies. Samples were collected from different regions of Lahore and evaluated on basis of their physicochemical, Mineral and Biological properties. Physicochemical analysis showed that only one sample of Brand A, B (multinational) did not justify the results against the nutritional label. Sodium, magnesium and sulphate of one sample did not justify the results against the nutritional. Arsenic metal was detected in sample number 1 (Result 0.01ppm) but did not exceed the Maximum Admissible Limit by PFA/PSQCA and WHO. Biological Analysis showed results of brands A, B, C, D, E and J were negative for pathogenic microbes. TPC was zero for brands B & D while brands A, C, E and J were reported with minor growth. Brands F, G, H and I reported with positive results for pathogenic microbes and also carry the huge CFU count for the TPC and Yeast in it. Brand F results was positive for Coliforms, E.coli and Pseudomonas. So, all the tested bottled water brands are ‘Fit to Drink’.
