In order to assess the distribution of manganese and iron contained in the two compartments of Wadi Tislit-Talssint, sampling campaigns were carried out weekly during May 2011 and an approach is represented by descriptive study and variance analysis. The results of these analyzes have shown the existence of a fairly high content of Mn in the stations so and SC1, the levels measured are markedly higher than the potability standard. Thus, the total average Mn concentrations in all stations in the studied waters are significantly different. On the other hand, the total average Mn concentrations in all the sediment stations studied are not significantly different; the total average Mn concentrations in all the stations of the mixture (water + sediments) studied are highly significant. In addition, no significant difference in metal accumulation was observed between the two compartments, manganese is more abundant at the station SO in water (1434 μg / L) than in the sediment. However, the origin could be natural and that contributes to this contribution in manganese, since the formation of the watershed is rich in Mn (limestone and marl). In addition, iron with a distribution similar to manganese, it abounds in all study stations, but with higher levels by than those found in manganese
