In order to evaluate the impact of potential pollutions on water quality in watershed upstream wadi Boussellem (North-east Algeria), evolution chemical composition waters Ain Zada dam was studied over a period ten years. Using linear model trends and principal components analysis (PCA) methods, have been detected quantified for substances that are connected with fertilizers domestic effluents. An increasing concentration is observed most these substances. The increase 88% COD, 66% BOD5 decrease 4.3% pH, suggests degradation O.M 85% by microorganisms. This accompanied 2% O2dis content. large increases E.C 76%, NH4 290% NO2 100%, related marked applications denitrification NO3 where latters declined 77%. These also amount human animal organic materials industrial waste dumped.Keywords: Pollution; Eutrophication; Boussellem; microorganisms,
