Quality Control of Drinking Water Supply in the Goh, Loh-Djiboua, and Nawa Regions (Côte d’Ivoire)

This study was conducted to evaluate the quality of public water supplies in the Gôh, Lôh-Djiboua, and Nawa regions, with a focus on the localities of Diégonéfla, Divo, Gagnoa, Guibéroua, Lakota, Oumé, and Soubré. A total of forty (40) water samples were collected and subjected to physicochemical and bacteriological analyses. In parallel, a consumer survey was carried out to assess perception of water quality. Survey responses indicated that the majority of the population regarded the water supply as satisfactory. However, laboratory findings revealed non-compliance with national standards for several physicochemical parameters, including residual chlorine, turbidity, iron, manganese, aluminum, and pH levels. From a bacteriological perspective, the presence of microorganisms such as total coliforms, Escherichia coli, and Enterococcus faecalis was detected in some samples, suggesting potential risks to public health.
