摘要

The problem of pollution affects the whole world groundwater. 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.
