Abstract: The organoleptic characteristics of water consumption explain their acceptability by consumers. The waters of some wells in Nioro are unpleasant to drink, causing the tap water rejection by consumer. The physicochemical characterization of these waters show that iron and manganese concentrations can reach respectively 1.58 mg. L^ (-1) and 1.14 mg. L^ (-1). But the substance indicators of pollution such as nitrogen compounds, nitrites and nitrates ions, are not detected (except in NTP water). The unpleasant taste of these waters might be due to Mn (II) ions, which are not eliminated by a simple chlorination.
