Characterization of Bottled water quality using water quality index in Minna Metropolis of Niger State Nigeria.

Abstract

Random samples of bottled drinking water in Minna metropolis were collected and analyzed using water quality index. This study was carried out to characterize the bottled drinking water using water quality index so as to assess the suitability of bottled drinking water from different sources with the study area. Ten samples were purchased at the sources of production for four consecutive months of April, May, June and July 2019 and analyzed for pH, Calcium, Total Hardness, Total Alkalinity, Chlorides, Magnesium, Sulphate, Nitrate, Iron, and Manganese. The results show that all the parameters analysed were all within the permissible limits of World Health Organization. The results obtained for the WQI from the different bottled water products were found to be varied from 4.96 to 21.65. These results indicate that the all the bottled water samples analyzed are safe for human consumption and for other domestic purposes. Effort should, however, be made to ensure the sustainability of the current method of bottled water production within the metropolis.
