摘要:In the final section of Bouregreg basin (Northern Morocco) a rap idly expanding process of urbanization is in progress, due to its proximity to Rabat, the capital of the Kingdo m. This work aims to study water quality of ground water in an area affected by anthropogenic sources of pollution from a landfill and agricultural activities. On a set of several water samples, main components and selected trace elements were analyzed. Geochemical classification of the waters was carried out. In the alluvial plain of the Bouregreg, the water quality deterioration is due mainly to the tidal seawater intrusion into the river up to 24 km upstream from its estuary on the ocean. This salty water feeds the shallow aquifer beneath to the river. This study has found that there is a significant release of heavy metals from the O um Azza waste landfill. The shallow waters also show the common contamination by agricultural fertilizers with high values of nitrates in irrigated areas
