Quality of Groundwaters of the Rural District EL Ganzra (Province of Khemisset, Morocco)

The study of groundwater quality in the rural commune of EL GANZRA by agricultural excellence is of importance for the use of groundwater for various activities (drinking, irrigation, patenting ...) to do a follow-up of several physicochemical tracers. there was held samples of 19 wells spread throughout the area concerned. Results emit conductivity and salinity highlighting the role of the effect on the geological nature of the water quality and that a change in MES and COT which confirms the presence of natural organic matter origin (productivity) or anthropogenic (human). The DBO5/DCO ratio is about 0.3 can be concluded that the water from these wells are quite loaded with poorly biodegradable inorganic components. For nitrates values are noted below the WHO standard allowable, except P19 in which there is a high value of 33mg / l which is probably due to agricultural activity characterized by the use of fertilizers.
