The present study was conducted to assess the impact of agricultural intensification and the spreading of untreated wastewater on the physical and chemical quality of groundwater in Kénitra (Gharb, Morocco). The physicochemical parameters monitored were: T°C, pH, EC, NH₄⁺, NO₂^-, NO₃^-, Cl^-, SO₄^2-, HCO₃, and the total hardness (TH) of raw water from boreholes on the Maâmora aquifer. The groundwater of the kenitra water table showed the following mean values: Temperature (20 ° C), pH (6.47), Electrical Conductivity (785.1 µs / cm), Nitrite (0.0093 mg / L), Nitrate (84.22 mg / L), Ammonia (0.093 mg / L), Chlorides (141 mg / L), HCO₃^- (5 meq / L), Total Hardness (13.9 meq / L), and Sulphates (17.7 mg / L). More specifically, the current study notified high concentrations of nitrates in some wells (up to 2692 mg / L). Hence, the effects of polluted groundwater should be highly concerned due to their serious health consequences. For sustainable use, policymakers must protect the aquifer from the uncontrolled development of agriculture and the spraying of unreasonable masses of pesticides, nitrogen and phosphorus fertilizers.
