As many rivers crossing urban region in Morocco, Martil’s river feeding the cities of Tetouan and Martil suffers from an organic and metallic pollution problem under the effect of a rising anthropological pressure. In fact the recent study has detected a surprising phenomenon of sediment enrichment exceeding 280 ppm for Cooper (1, 21 mg/l), 90 for Lead (0, 35 mg/l), and 3 ppm for Cadmium (0,016 mg/l) downstream. The present work objective is to examine the reality of this metallic pollution and to understand the nature of the polluting sources. The metallic elements analyses have been done in sediment with an appropriate technical means. Results interpretation has been used by indices of contamination: Factor of enrichment, to identify the metal origin enriching sediment. This work has shown that the municipal dump situated at the river shore has a moderate and located impact on sediment for: Cu, Pb, and Zn. On the rest of the zone of study no other impact by the Pb has been detected, but the result indicated the existence of a diffusing geogenic source, recording relatively elevated degrees of the seven metallic elements in comparison to the upstream of the river.

At present, although there are several studies and waste management strategies at the international echelon, but there is no consensual method for the characterization of waste. Also at the national level reducing the quantities of final waste with the development of recycling branches and made the valuation and reducing pollution linked to the storage and disposal of waste is a regulatory objective, political, economic and priority order for the preservation of the environment.It remains clear that a single parameter is not enough to characterize and describe such heterogeneous and hazardous waste such as those in our country: with more than 60% organic matter, a high humidity and sometimes containing hospital and / or industrial waste. The different analysis methods followed in this work is devoted to the characterization of Household Garbage and assimilated. The particularity of the sampling approach was highlighted on the landfill site based on plans of town-collect and to provide the maximum information on the Household Waste of Tangier. later laboratory work was carried out.The study of the composition of the waste is an essential step for a sound management for a number of reasons,including the need to estimate the quantity of material produced, identify their generation source to facilitate the design of equipment and treatment processes, defining the physical, chemical and thermal properties of the waste and to ensure compliance with laws and regulations.

Pollution of superficial waters is one of the most answered aspects in the world and especially in the Mediterranean. The Mediterranean countries like Morocco is settled in a serious policy for the conservation of resources in superficial waters or groundwater, reducing the rate of the pollution load reaching the different streams and also, practicing techniques of cleanup especially in the Mediterranean watersheds whose the watershed of Martil which represents the largest one in the north western of Morocco. The results of physicochemical parameters recorded at different stations, show a high pollution load in stations located in the center of urban and industrial areas, translated by high rates of TSS, COD and BOD5 and consequently low levels of dissolved O2. The analysis of heavy metals, have led to the remarkable presence, by location, of iron, aluminum and lead, by cons, the results showed low contents of zinc, copper and cadmium.
