Abstract:

Globally and locally, there is a significant shortage of potable water for domestic and other uses. Water quality refers to the assessment of its physical, chemical, and microbial properties. Ensuring the potability and suitability of water is critical for reducing human mortality, preventing the destruction of aquatic ecosystems, and ensuring the safe production of goods that require high-quality water. Water is considered of good quality if its physico-chemical, heavy metal, and microbial concentrations remain within permissible limits set by international and national regulatory standards. Thirty (30) commercially packaged sachet water samples from popular brands were randomly but evenly selected from three (3) Local Government Areas: Amuwo-Odofin, Ojo, and Lagos Mainland, within the Lagos Mainland area of Lagos State, Nigeria. These water samples were annotated and analyzed in the laboratory for their physico-chemical, heavy metal, and microbial parameters using standard scientific methods. The results indicated that all the analyzed water samples met the threshold limits for physico-chemical, heavy metal, and microbial parameters as established by international and national regulatory standards.The commercially packaged sachet water samples analyzed from the three (3) Local Government Areas in the Lagos Mainland area of Nigeria were found to be potable, free from waterborne infectious microbes, heavy metal contamination, and physical impurities.
