Effects of anthropogenic activities on the quality of surface water of Seybouse River (northeast of the Algeria)

This work aims to study the physico-chemical typology of Oued Seybouse river waters that receives the sewage discharged by the localities and the industries located along this stream and the determination of the sources of pollution. These wastewaters contribute to the degradation of Oued Seybouse river water quality. Five water points were sampled on the bed of Oued Seybouse since the source Medjez Amar on the outskirts of the town of Sidi Salem (Annaba), with a monthly frequency during duration of 2 years (on 2012 and 2013). We analyzed eighteen (18) physic-chemical parameters (temperature, pH, conductivity, chlorides, sulfates, phosphates, nitrogenous components, oxygenates dissolved, oxidizible material, dry residue, total hardness, suspension materials ….).
