Abstract:
Twenty five brand of commercially available bottled water were randomly collected from local markets to check the chemical quality for the confidence-building of the consumers. The suitability for human consumption was assessed according to WHO and EU guidelines/directives. Various water quality parameters along with anionic and cationic balance were analysed by standard APHA and AWWA methods. Forty percent of the samples had higher conductivity ranges as per EU directives while micronutrients (Cu+2, Fe+2, Mn+2, Ni+2, Zn+2) were found entirely absent. Sodium was marginally higher in one sample as per WHO guidelines. Forty four of the samples had confirmed presence of arsenic (As) between the range of 1-11ppb. It is therefore, concluded that majority of the available bottled water brands conformed to the guidelines / directives of WHO/EU for the over all quality of drinking water.
