Abstract

The purpose of the present work and evaluation of the impact of pollution on the water quality of the Sidi Chahed dam (Meknes, Morocco): it focuses on the analysis and evaluation of metal contamination of sediment by using an index of contamination which is the ratio of the metal content of the reference content (geochemical background), spatiotemporal variations in grade sediment Fe, Pb, Cd, As, Cu, Cr, Mn and Zn reveals the presence of significant contamination of the elements Pb, Cd, Cu, Mn and As. However, contamination indices (content metal / reference content) and indices means of contamination (Icm < 2) registered for the eight trace elements analyzed Cd, Cu, As, Mn, Fe, Zn, Pb and Cr show a state of unpolluted to moderately polluted. The sources of contamination are probably related to runoff, erosion of agricultural land, discharges of domestic sewage and traffic. © 2017, University of Mohammed Premier Oujda Morocco.
