Abstract

Adequate supply of potable table water is a basic necessity for all mankind. Unfortunately,this basic necessity of man has been grossly deprived especially in the developing countries. Water meant for consumption must be potable: free from contamination by microorganisms and possess stable physicochemical parameters. And this is the essence of this research study. In this study, physico-chemical parameters such as colour, pH, odour, temperature and microbial indices: Escherichia coli, Klebsiella pneumonia, Salmonella typhmurium and Streptococcus aureus were investigated in potable packaged water sold in Nnamdi Azikiwe University, Nnewi Campus, Anambra State,Nigeria. Six different bottled and sachet water samples obtained from different manufacturers labeled B1,B2,B3,B4,B5,B6 and S1,S2,S3,S4,S5,S6, respectively were examined physically, chemically and microbiologically. Physical examination of the samples showed that they were colourless and odourless. Chemical examination of the samples showed they were within the WHO standards for temperature and pH except for water samples S1, B4 and B5 whose pH (8.6; 6.2 & 6.0) deviated from the standard . Water samples S4, B3, B4 and B5 indicated presence of E. coli where as S6 indicated presence of Klebsiella pneumoiae. Streptococcus aureus was present in B3. From our study, its suggestive that the packaged water analyzed were not chemically and microbiological fit for consumption though this need to be further investigated. P.N. Ogueche | P.A.
