Abstract: During the period spreading from August 2005 to July 2006, we achieved a comparative survey between the quality of waters rejected by the industrial zone of Skikda and the quality of waters appropriated on three witnesses` sites in a natural habitat. The survey has been done on a period of 12 months and carry on 10 stations with a total withdrawal of 120 samples and a frequency of 1680 different analyses achieved. The results of univariate and multivariate statistical analyses show, the existence of significant differences between the 10 studied stations for all physicochemical characteristic studied, and the absence of significant differences for the four inorganic elements (metals). The classification of the 10 stations in homogeneous groups with single linkage and squared Pearson Distance gives a dendrogram with 4 homogeneous groups of stations to the level of similarity of 85,48%.
