This study aimed at assessing the effect of storage on the physicochemical properties of some brands of sachet water sold in Ahmadu Bello University, Zaria, Nigeria. For the period of six months, each month, eighteen sachet water samples from six different brands sold within Ahmadu Bello University, Zaria, Nigeria, were randomly collected from the production sites within 24 hours of production. Physicochemical properties of the samples were determined using APHA and EPA analytical methods in the laboratory. The results obtained from this study revealed that, no full labeling compliance. The concentration of various physicochemical properties did not exceed the limits recommended by Standard Organization of Nigeria for drinking water standard except total hardness in some brands was outside the recommended limits after collection. Storage within the shelf life revealed that ambient temperature may favour increase in the physicochemical properties of the sachet water than when refrigerated even though both storage conditions may lead to increase and decrease in the values of some variables. Among the brands analysed after collection for pH, conductivity, total dissolved solids, and chloride are significantly different (P˂0.05) while temperature, nitrate, sulphate, hardness and phosphate did not differ significantly (P˃0.05).
