This study evaluates the quality of sachet and bottled water in Ile-Ife, Osun State, Nigeria. It also provides insights to achieve universal access to safe drinking water and sustainable water resource management.A list of water production companies in the study area was obtained from the National Agency for Food and Drug Administration and Control (NAFDAC). Physical and chemical analyses; electrical conductivity (EC), total dissolved solids (TDS), turbidity, pH, total alkalinity, hardness, nitrates, and sulfites were conducted on each sample for quality and potability. Laboratory results were compared with the World Health Organization (WHO) and Nigeria Institute of Standards (NIS) publications on drinking water quality.Based on the analysis of the results, out of the 58 samples collected, 16 samples (20.51%) of the samples shows total alkalinity levels below the WHO permissible limit of 20 mg/L, potentially affecting the water's buffering capacity and pH fluctuations. Additionally, 11 samples (14.10%) have total hardness levels exceeding the WHO limit of 100 mg/L. Furthermore, 38 samples (32.05%) shows pH levels below the NIS acceptable range (6.5-8.5), indicating potential acidity and corrosion risks. However, EC and turbidity levels are within limits for all samples, ensuring the water's mineral content and clarity meet the permissible standards.
