Well water samples from sixteen locations were collected and analysed within Warri metropolis to ascertain their quality using water quality index (WQI). The WQI was determined based on thirteen physico-chemical parameters. All the physico-chemical parameters of the well waters analysed were within standard regulatory limits. The water quality rating and water quality index (WQI) of the sixteen locations range from 23.61 (Ovwian) to 32.95 (Ugbomro) indicating the water quality to be of good quality. Most of the well water sampled are used for drinking purposes and as a result are provided with casing on the side called “rings” while the top is usually provided with a cover and are locked to prevent stray objects and other unwated materials from entering the well. This provides a good protection and prevention mechanisn for all the well waters. Overall the results indicate that the different well waters samples analysed from Warri Metropolis are safe for human consumptions therefore may not need further treatment.
