In full extension, the city rejected those waste waters and without any prior treatment to the Oued Meboudja, which led to the deterioration of the quality and aesthetic all of its waters. The study of various pollution parameters shownthe vulnerability of the water of the Oued Meboudja against the pollution from urban waste water, and found that in all waters of the Oued Meboudja are unacceptable because they exceed the normative limits generally accepted e. in order to conclude on the nature of pollution, a series of physical and chemical analysis to determine the degree of pollution of the Oued, has given a preliminary overviewof the current situation. Water Quality of Oued Meboudja pleads for non-conformity of water to be used directly in all areas.

Key Words: impact, Oued, pollution, reject, waste water1. Introduction Has long been considered renewable and inexhaustible water resources in recent decades has a real phenomenon of rareness. The degradation of the quality and excessive use of this resource are the main causes of this phenomenon. And often when environmental disasters that we become aware of the damage done by man in the water. Become the receptacle of wastewater from industrial,urban and agricultural, streams in Algeria in recent years have reached an alarming level of pollution. [1] An industrial vocation, EL HADJAR is one of the most important cities in the wilaya of Annaba, fully extended over, the region drains the most of these waters to the Oued of Meboudja an important effluent of the river Seybouse. As a result, the water quality of the river is constantlydeteriorating. Deal with this situation that affects more and more quality of life in this region and the neighboring ones, we set a target in this study to identified the impact of urban waste water of the city of El Hajar on a water quality of the river Meboudja.

2. Presentation of the study area Oued Meboudja is located in the lower plain of the Seybouse (NE Algeria), in the sub-basin of the Oued Meboudja (Fig.1) Daïra EL HADJAR, it is limited to thewest by the Massif metamorphic Belilieta Boukhadra and to the south by the extension of the mountains of El-Kala and Chaffia. The eastern edge of the area consists of the Oued Seybouse, witch receives Meboudja near 8 km from the Mediterranean which is the northern limit of the study area. The Oued Meboudja is characterized by a steady flow in winter; its power is supplied by rain water, anddrainage Fetzara Lake, located in the SW. Its speed can reach then 16m3/ s. In summer, the contributions are made primarily by the exit of the lake (the flows oscillate between 1 and 5 m3/s. The Oued also receives on its journey urban discharges of several villages (Hajar Diss, Sidi Amar, ElHajar, ..) and industrial (steel mill, "Mittal Steel", Industrial Zone Chaib, Pont Bouchet, ...) .
