Abstract
Our study aims to assess the physicochemical and bacteriological quality of water in Oued Sebou. Of particular interest is its significance for domestic and agricultural purposes, as well as the imperative to monitor pollution levels. Downstream of Kenitra city, the compounded effects of urban, industrial, and agricultural activities exacerbate environmental degradation annually. We conducted analyses at four sampling stations, strategically positioned both upstream and downstream of discharge points, encompassing two industrial and two urban effluents. Fifteen key physicochemical parameters were scrutinized, including temperature, pH, conductivity, suspended solids, dissolved oxygen, biochemical oxygen demand, chlorides, nitrites, ammonium, nitrates, sulfates, NTK, turbidity, total phosphorus, and iron. Additionally, microbiological parameters such as fecal coliforms and fecal streptococci were examined. Our findings underscore a significant disparity in water quality between upstream and downstream regions, with the latter exhibiting substantial degradation in comparison to established Moroccan standards for surface water quality.
Keywords: Surface water, Oued Sebou, Bacteriological quality, Physicochemical quality.
