Abstract: The physicochemical characterization of water of the Mbe Plateau was carried out starting from thirty-two (32) samples of water taken between November 2017 and May 2018 in six months (rain season with a seasonal intercalation enters mid-January and at the end of February known as small dry season). Four (04) boreholes (Massa, Dieu le veut, Ingha and Ivoumba), three (03) rivers (Maty, Mary and Gamboma) and one (01) well (Ignié) were sampled during this study. The study of this water was based on measured parameters in-situ (the temperature, TDS, pH, the EC, dissolved oxygen, dissolved complete iron and salinity) and at the laboratory in particular: hardness, Ca2+, Mg2+, K+, Na+, Al3+, NH4+, Cu2+, Fe2+, Pb2+, Cd2+, Mn2+, Cl-, HCO3-, SO42-, NO3-, PO43- and alkalinity. The elements measured in situ were checked at the laboratory to reassure results. The results obtained showed that the values of measurements of the physicochemical parameters of analyzed water were all in conformity with the standards prescribed by WHO for the drink water, except in the case of the abnormal temperature proven with an average of 27°C and an average pH of 5.0 what confirms the acid character of water in all this zone of study. These results were treated starting from a hydrochemical method, by using the diagrams: of Piper, of Stabler, Schoeller-Berkaloff, Stiff, Wilcox and statistical methods traditional with software XLSTAT. The analysis enabled us to highlight the prevalence of facies chemical total chlorinated and sulphated calcic and magnesian in this water of the Plateau of Mbe. The dominant ions are the chlorides for the anions and magnesium for the cations.
