Assessment of the quality of some sachet water brands in the Sunyani Metropolis of Ghana

The study assessed the quality of the most patronised sachet water in the Sunyani Metropolis of Ghana. Six sachet water products were selected based on consumers‘ responses to a questionnaire survey. Samples of the products were purchased and stored for monthly phusico – chemical, nutrient and microbiological analyses for the period of two months. The analyses were done according to standard methods for the examination of water and wastewater. The result indicated that physic-chemical and nutrient levels were all within the World Health Organization (2007) and the Ghana Standards Authority (1998) permissible limits. The bacteriological analysis also showed that all brands of sachet water studied were not contaminated except for total coliform which was recorded in one of the product at a level of 9.1MPN / 100ml. No significant differences were recorded during the month of storage among the same brands. However, for the physico-chemical parameters,differences in mean values were significant for the different brands. Thus, it can be concluded that the sachet water products studied in the metropolis is generally of good quality. Nonetheless, sachet water products in the metropolis should be monitored regularly for microbial quality in order not compromise the standards.
