TYPOLOGY OF WATER QUALITY IN THE LOUKKOS RIVER ESTUARY (Morocco)

Abstract

Water plays an important role in the Moroccan economy: including tap water by humans. However in the last decades, we noticed the deterioration of stream water quality due to industrialization and human activities.

The study of the physico-chemical effluents characteristics proved of the industrial units of the Loukkos river estuary shows, that they are at the origin of important organic discharges. Indeed, the waters of draining of the rice fields are at the origin of important organic discharges dragging strong concentrations in suspended matter and nitrate, the general effluents present a high salinity, a strong concentration in organic carbon. These emissions cause risks of poisoning for the receiving environment. It especially conjugates him by the deterioration of the quality of the waters of the Loukkos river estuary to the level of the section downstream of this estuary.
