Physico-Chemical and Microbial Characterisation of Water from the Abengourou dam in Eastern Côte d’Ivoire

The water from the Abengourou dam is used for production of drinking water. This study aims to characterise this resource in order assess quality monitoring and sustainability operation. Six sampling points were identified, four which at main entrances, one inside body another dam. Samples taken three different depths during two seasons. In total, some forty physical, chemical microbiological parameters monitored thirty-six samples year. results obtained show an inter-seasonal variation monitored. waters are very weakly mineralised not turbid. highest turbidity wet dry seasons respectively 6.5 NTU 11.1 NTU. electrical conductivity between 173 190 µS/cm season 149 163 μS/cm season. mainly due rising levels evaporation Concentrations iron, pesticide residues, manganese ortho-phosphate above WHO guidelines recorded. Average iron 0.84 0.53 mg/L respectively. Manganese reached 2.02 Organohologenes found up 0.04 µg/L high-water period. A greater presence germs indicating faecal contamination was human or mixed human-animal origin depending on point. recorded point P2, represents urbanised part catchment area several analysed.
