Origin of Mineralization of Groundwater in the Tongo Bassa Watershed (Douala-Cameroon)
Autor: Y. Ndje, C.R. Ebonji, S. Ngo Boum-Nkot, Beatrice Ketchemen-Tandia, H. Emvouttou, Frédéric Huneau
Publikováno v: Research Journal of Environmental and Earth Sciences. 7:29-41
The Tongo Bassa watershed is located in the Douala sedimentary basin with the equatorial humid (4000 mm/year) type climate. The groundwater is weakly to strongly mineralized with values of conductivity less than 1450 μS/cm. The water type that predo
