    ABSTRACT: The coastal areas are the locus of activities requiring water of good physicochemical quality: recreational uses, aquaculture and fishing. Thesis areas are under the direct influences of wadis and wastewaters, which pass by the contributions of watersheds, urban and industrial discharge. Thesis discharges result, when the renewal of water masses is small compared to release, significant deterioration of water quality and marinades ecosystem. This study focuses one year assessment of water quality urban sewages from coastal urban centers western (Oran), with the aim of assessing the state of contamination by draws metals (Cd, Pb Zn and), have well ace the assessment of the physico-chemical quality of marinades waters to determines the potential impact of metal pollution one the west coast Algeria of. Lead has average concentrations high enough at the three studied sewages: 0.23 mg.l-1 at the urban sewage Oran of (standard deviation: 0.22 mg.l-1). Yew heavy metal concentrations vary greatly from one sample to another; have reflected in the standard deviations, no lasting changes obvious is. Only average levels of cadmium exceeding the normative.
