Abstract: The Oued Guigou catchment area is the upper part of the Oued Sebou and represents 52 % of the Haut Sebou catchment area. It is part of an original morphostructural context between the Middle Atlasic Cause to the north and the Middle Atlas folded to the south. Sampling campaigns on surface water and sediment provide details of heavy metal contents. The results of the analyses revealed that the levels of certain heavy metals are below relative standards and that others were below detection limits but do not raise any ecological concerns. The high content of certain metals (Cr, Ni) has a natural origin and outweighs the anthropogenic origin. These fluctuations are spatial in nature (upstream to downstream.
