The deficit in drinking water resources in the District of Abidjan remains the major concern of the decision maker. The Aghien lagoon stands as one of the most interesting alternatives. However, studies show the levels of pollutions of this resource without lighting out on the causes and sources of these pollutions. The present study extends over the entire catchment of the Aghien lagoon which reveals the presence of urban areas and agricultural activity areas. This raises real concerns for the Ivorian authorities. This study suggests making cartography of the risk levels of pollution on the Aghien lagoon by the surface runoff on the watershed to enlighten the decision-makers on the possible measures to be taken for the protection of this resource. It emerges from it that the risk of contamination of the lagoon is very likely. Agricultural and domestic best practices inside the pouring pond are compulsory to fight against the pollutions of this resource.展开更多

The purpose of our present study is to evaluate the impact of contamination from residues of industry and agriculture, and discharge of untreated domestic wastewaters on the physical, chemical, metal and bacteriological water quality of Maamora’s tablecloth (Sebou bassin, Kenitra, Morocco). The physicochemical parameters followed are: T ℃, pH, EC, NH4+, NO2-, NO3-, CI-, F-, HCO3-, CO32-, SiO2, SO42-,?Na+, Ca2+, Mg2+, K+, Pb2-, Cd2+, Fe2+, Cu2+, Zn2+, Ni2+, B3+, Dry Residue, Turbidity, Total Hardness (TH), Dissolved O2, Oxidisability, total and fecal coliforms, faecal streptococci and total and faecal germs of raw water from the boreholes. The physical, chemical, metal and bacteriological quality shows that the groundwater which is used as drinking water in the city of Kenitra and adjacent towns is generally good. However, high concentrations of nitrates (over 210.8 mg/L) and other metals (185 μg/l for lead;58.98 for nickel;187.3 μg/L for iron;2204 μg/L for zinc) in some wells are worrisome because of the serious health consequences.展开更多
