 en The effect of storage on Physical, Chemical and Bacteriological characteristics of Sachet and bottled water marketed in Ibadan Metropolis, Oyo State. Nigeria


This study assessed the changes in physical, chemical and bacteriological quality of drinking water stored for a period of three months. Ten (10) different companies’ water samples each of bottled water (B) and sachet water (S) were randomly selected for the study around Ibadan Metropolis. Experimental method was used to check the levels of the different parameters in each of the samples within first week (W) of production and after three months (M) of storage. The results obtained were subjected to both descriptive and inferential statistic. The concentration of total suspended solid were noticed in higher quantity in sachet water; S3M, S4M, S5M and S7M with values of 1.75±0.35, 1.90±0.14, 1.35±0.21, and 1.55±0.07 mg/L respectively. Total dissolved solid showed increased in all sample analysed after storage as with other chemical element except that lead showed decreased with storage. Almost all the parameters analysed had concentrations within the SON/WHO Standards except pH with samples: B1W (6.11±0.07), B2W (6.19±0.01), B10M (6.45±0.35), S2W (6.45±0.07), S7W (5.70±0.14), S9W (5.80±4.10) and S10W (5.30±0.00) which were slightly acidic and below the 6.5 minimum standards. There was also growth of Coliform Count of 0.001±0.00 after 3 months of storages in two bottled water (B5M and B6M). The study concluded that storage of potable water for 3 months should changes in the physical, chemical and bacteriological parameters and the intrusion of heavy metal such as Pb in some potable water portray a great deal of harm to consumer when consumed.
