This study investigated the effect of storage on some sachet water quality indicators over a twelve week period. Three brands of sachet water were collected within 24 h of production and analyzed for pH, nitrate, phosphate and dissolved oxygen. pH values increased significantly in all brands after week 8 of storage. Nitrate and dissolved oxygen values decreased throughout the investigation period while phosphate values increased in all brands tested. The brands showed various degree of variation over the period of study for the chemical quality indicators. All brands analyzed were within permissible limit by World Health Organization (WHO). However, continuous storage can significantly alter the chemical quality indicators to a level that exceeds the limit set by WHO; hence, becoming harmful to human health. Therefore, it is recommended that sachet water should not be stored for more than 12 weeks from the date of production.
