摘要：Recently, according to a survey carried out in Oued El Abid River by Oum Er-Rbia Hydraulic Basin Agency concerned the surface water quality, the downstream course is undergoing continual degradation in its water quality comparable to the upstream. This study comes to localize the sources of pollution and explain the process of degradation, which affect the water quality in that area. For this purpose, an inspection of the place has been done during January 2017 to cover the entire zone limited the affected part of river, followed by a survey, which interests to water quality and the groundwater depth. The inspection doesn't show any direct liquid discharge into the river, meanwhile the water quality degradation is related to the underground sources through river- shallow- aquifer exchange process, when the obtained results from the survey showed that severe parameters are involved in the degradation of groundwater, as the geology and agricultural activities. Combining these results with flow direction in groundwater, it is clear that pollutants are transported to the river via the river-shallow aquifer exchange process, which affects its quality. Based on the finding results, this study will give the decision makers a simple view to a complex pollution processing.
