This study aims to assess the physico-chemical and mineral composition of water consumed in Daloa. The samples taken from ten sites made it possible to determine the biochemical composition of these waters. Using standard and referenced methods, the chemical physical parameters and the mineral composition of these waters were evaluated. They are generally acidic with pH values ranging from 3.98 to 6.30. These waters are weakly mineralized except for the samples from GARAGE (451.33 µS/cm) and ORLY 1 (681 µS/cm) districts, which have values above the standard prescribed by WHO (˂ 400 µS/cm). In addition, the different types of water in Daloa are generally cloudy except for water from the EVECHE spring, which has a turbidity of 0.17 NTU below the standard for drinking water. These Daloa waters contain minerals that have concentrations that meet the standards prescribed by the WHO for drinking water. These are calcium, potassium, sodium, nitrates, chloride, sulphide, bicarbonates, iron, copper, chromium, zinc, lead. On the other hand, the concentrations of arsenic and cadmium in the waters of TAZIBOUO, ORLY 1 & 2, GARAGE, EVECHE and the Pastoral Institute are high. Also the Water Distributed by the Company of Côte d’Ivoire called in french ̏ Société de Distribution d’Eau de Côte d’Ivoire ̋ (SODECI) contains a significant amount of cadmium and aluminum. The consumption of this water can therefore be dangerous for the health of consumers if no action is taken by the hygiene service of the municipality of Daloa.
