Water quality is a description of water's chemical, physical, and biological properties in relation to its intended use(s) and a set of standards. Water quality has deteriorated as a result of pollution from both point and non-point sources. As a result, any specific source's water quality can be investigated using physical, chemical, and/or microbiological parameters. The term water quality index (WQI), which is a rating reflecting the composite influence of different water quality parameters, is one of the most effective tools for communicating information on water quality. The Water Quality Index (WQI) provides a single number that expresses the overall water quality at a specific location. Nigeria employs the Water Quality Index (WQI). Between January and August 2014, researchers at the Department of Microbiology at Ekiti State University in Ado-Ekiti, Ekiti State, Nigeria, used an experimental study design. Among several developed water quality indices, the study used the Weighted Arithmetic Water Quality Index (WAWQI) method, which categorizes water quality based on purity. The WAWQI was calculated using physicochemical parameters such as pH, total dissolved solids, turbidity, total hardness, calcium, magnesium, sulphate, chloride, and nitrate. Standard methods were used to determine the parameters. The calculated WAWQI values for borehole, stream, pipe-borne, well, spring, and packaged water samples were 54.16, 65.12, 67.46, 56.29, 46.08, and 49.59, respectively. This result indicates that the analyzed water samples from various sources had poor water quality, with the exception of spring and packaged water samples, which have good physico-chemical qualities and are thus safe for human consumption.
