The knowledge of the physicochemical characteristics of Inaouene surface water constitutes a means of investigation for the assessment of the risks of pollution and the contamination status of these surface waters. The study initially focused on the physicochemical bacteriological study and the content of some heavy metals in the River waters. The first results revealed relatively high levels in nutrients, DCO, BOD5, calcium and magnesium. The content Cu, Cr and Pb is superior than relative standards, which would be due to the craft activities of the city of Taza as well as to the domestic liquid discharges on this city. The bacteriological investigation revealed a large concentration of these waters in coliforms and faecal streptococci. This allowed concluding that the quality of the Inaouene surface waters is much degraded.

Author Keywords: Surface water, Physicochemistry, bacteriology, heavy metals, degradation.

Abstract: (french)

La connaissance des caractéristiques physicochimiques des eaux de l'Inaouène constitue un moyen d'investigation pour l'évaluation des risques de pollution et l'état de contamination de ces eaux de surface. L'étude a porté tout d'abord sur l'étude physicochimique, bactériologique et enfin la concentration de certains métaux lourds dans les eaux de ce fleuve. Les premiers résultats ont révélé des teneurs relativement élevées en éléments nutritifs, DCO et DBO5 et en calcium et magnésium. La teneur en quelques métaux lourds s'est révélée supérieures aux normes relatives, tels que le Cu, le Cr et le Pb, ce qui serait engendré aussi bien par les quelques activités artisanales de la ville de Taza et aux rejets domestiques liquides de cette agglomération. L'étude bactériologique a révélé une grande concentration de ces eaux en coliformes et streptocoques fécaux. Ceci a permis de conclure que les eaux de surface de l'Inaouène présentent une qualité très dégradée.

Author Keywords: Eau de surface, physicochimie, bactériologie, métaux lourds, degradation.
