- In order to evaluate the degree of sediment contamination by metallic trace elements in the watershed of Oued Inaouene (North-East of Morocco), samples of surface sediments were taken along the river and at the level of the Idriss 1st dam. The objective was to obtain thorough knowledge of the environment (metallic element content, organic matter content, granulometry, and pH, EC, CaCO3 content) in order to identify the degree of pollution in these sediments. The results of analysis have highlighted a contamination accentuated by Ba, Sr, P, Cu, Pb, In fact, this element is present at very high levels, with a maximum content ppm for the samples taken upstream of Oued Inaouene. This increase is related to the physicochemical conditions of the environment, despite the diversity of sources of pollutants. The analysis of hazardous heavy metals showed the values under the detection limits. The qualitative study allowed to identifying the source of contamination, it is an anthropogenic source related to the discharges of cities in vicinity of Oued Inaouene, and natural considered as the main source of pollution by trace elements of sediments that constitute an important reserve of pollutants in the environment.
