摘要:The present work is to assess the quality of water of the Oued Moulouya in cities of Outat El Haj and Missour, in order to have the level of collaboration of the domestic pollution of these two cities to the degradation of this ecosystem. This study concerns the analysis of physical-chemical parameters (T °, pH, EC, turbidity, TSS, O2, BOD5, COD, MO, Cl, TH, HCO3-, PO43-, P, and NO3-, NO2- , SO42-) of the Oued Moulouya waters in Outat El Haj and Missour to establish a diagnosis of the state of pollution of surface waters of this river. Thus, the water samples were collected at six stations for one year from November 2014 to October 2015 (12 samples). The analysis results show that the water of stations are bicarbonated with calcium and magnesium and they also show that in the stations, where the wastewater are discharged from the cities of Missour and Outat El Haj, there is an increase in the levels of BOD5, PO43-, chlorides, TSS, COD, MO, and a decrease in the dissolved oxygen levels. Analysis of nitrates and orthophosphates of the water give very low values. The values of certain parameters such as temperature, the potential of hydrogen, conductivity, alkalis, sulphates, chlorides generally testify that the waters of the Oued are of good quality according to Moroccan standards. Furthermore, the pollution degree differs from one site to another depending on the distance and the remoteness of the source of pollution.
