Background: With the recent increase in the consumption of sachet and bottled water in major cities and towns of Nigeria due to lack of portable drinking water, there is need to investigate the prevalence of possible contaminants in these water that may have toxicological effect on human when consumed.

Aim: Quality assessment of sachet and bottled water produced and/or sold in Ibadan, Nigeria was the aim of this study. Place and duration of study: This research was carried out in Ibadan, the Oyo State capital of Nigeria between November 2018 and February 2019.

Methodology: Twenty sachet and five bottled drinking water brands; making a total of 25 brands from different manufacturers were used for this study. They were purchased randomly from local markets, shops and street vendors within Ibadan metropolis. They were clearly marked for easy identification and transported to the Quality Assurance Laboratory of Water Corporation, Eleyele, Ibadan for immediate analysis. The samples were examined physically and information on the packages were recorded. Each product was carefully opened to avoid contamination. The physical, chemical and bacteriological qualities as well as the mineral composition of all samples were analyzed using standard methods and results were compared with the recommended WHO/NIS guidelines for quality water.

Results: Physical examination indicated that all the sampled water were registered with NAFDAC but 70% of the sachet water had no manufacturing and expiry dates. The results of physical, chemical and bacteriological qualities as well as the mineral composition of sachet and bottled drinking water analyzed showed that 90% of the values were within the guideline of WHO/NIS for quality water.

Conclusion: Though, the average temperature values of both the sachet and bottled drinking water samples were significantly above the WHO/ NIS standard, it did not have any effect on their microbiological quality properties. Total coliforms, faecal coliforms and enterococci bacteria that principally characterize drinking water quality were not present in any of the water samples. Generally, the results obtained in this study indicated that sachet and bottled drinking water produced and/or sold in Ibadan metropolis were of good quality and hygienic for consumption.
