The study has been carried out in November 2007 and July 2008 on eight wells located in the vicinity of Fez stream and Sebou River which waters are polluted from discharges issued from the urban area of Fez city. The obtained results showed important concentrations in heavy metals mainly in wells drilled inside the alluvial aquifers and located more meadows of the Fez stream and Sebou River. The comparison of the contents of heavy metals between shallow aquifers and surface waters along Sebou River indicated a very narrow correlation which can be explained by hydrogeologic interaction between these waters.
