Microbiological and physico-chemical characterisation of well water in the town of Korhogo, Côte d’Ivoire

Water is essential to the life of every living organism. The water used by consumer must be safe for preservation his health. objective this study was assess quality well in households city Korhogo. To do this, samples were taken from wells different households. Parameters such as pH, temperature, electrical conductivity and total dissolved solids measured at sampling sites. Nitrates ammonium determined spectrophotometric methods using sodium salicylate indophenol blue, respectively. membrane filtration technique has been enumeration coliforms, Escherichia coli, fecal enterococci, sulfite-reducing anaerobic bacteria, yeasts moulds. agar incorporation method mesophilic aerobic germs. non-conformity relative pH 73%. All contaminated with nitrates ammonium. Non-compliance rates 80% 53% obtained germs, E. coli enterococci 100% each indicator. No spore sulphite-reducing clostridia identified. Contamination (mould) 67% (yeast) recorded. moulds isolated various belong genus Aspergillus. not suitable human consumption. These waters require treatment or household residents switch other sources drinking water.
