Abstract:
There is increase demand for sachet water as a result of non-availability of reliable safe drinking water and this has left the impression that most sachet water offers a healthy, safer and water with better and good quality. Despite general acceptability of packaged sachet water, previous work showed that there is a challenge associated with its quality as a result of isolation of some microbes and non-compliance with expected parameters. The current work is focus on physicochemical and microbiological analysis of selected sachet water vended in Akure, Ondo State, Nigeria. Five samples of sachet (A= Primus table water; B= Bofa table water; C= Zion table water, D=Aktols table water and E=Edna table water) water obtained from five different areas were analyzed for physicochemical and microbiological parameters using standard analytical methods of Association of official Analytical chemists (AOAC). The result of microbial analysis revealed that all the water samples referred to as samples A, B, C, D and E respectively had total plate count of 7.0cfu/ml, 4.0cfu/ml, 1.0cfu/ml, 15.0cfu/ml, and 3.0cfu/ml respectively. This showed that sample A, B, C, D, and E did not exceed the standard of total plate counts. The entire samples resulted at 0 counts for Escherichia coli. Samples A, B, C, D and E tested negative for Coliform test, Fungi test and Salmonella shigella test. The chemical analysis showed that all the samples meet up with the recommended standard of pH (6.5-8.5) by World Health Organization (WHO), United Nations International Children's Emergency Fund (UNICEF) Standard ganization of Nigeria (SON) and National Agency for Drug and Administration Control (NAFDAC). The temperatures were not significantly different and did not exceed standard limit of 370C. The total dissolved solid also did not exceed the limit of 500ppm as recommended by World Health Organization /United Nations International Children's Emergency Fund (WHO/UNICEF) and the conductivity limit was not exceeded. All the samples did not exceed limits for zinc, chloride, iron, nitrate, nitrite and flouride which are 0.3mg/l, 250mg/l, 0.3mg/l, 50mg/l, 0.3mg/l and 15 mg/l respectively. All the samples were significantly different for each parameter except for lead, copper, free chlorine and manganese of which the entire sample were all the same.
