The Hassan II dam, located in the province of Midelt, is one of the largest dams in Morocco. Its main purposes are drinking water production and irrigation. However, the location of this dam, about 10 km downstream from the abandoned mining site in Zaida, prompted us to conduct this study, which aims to assess the contamination of the water of this dam and its two main tributaries, the Moulouya and Ansegmir wadis, by undesirable metal elements (zinc and copper) and by some toxic metals (lead, cadmium, and arsenic). In total, 24 samples were collected during the study period (November 2011 to August 2012). The results of the various analyses reveal disturbing levels of lead and cadmium in the Hassan II dam waters, exceeding the mandatory limit values of the different categories proposed by the Moroccan standard for water intended for the production of drinking water. The metal contamination of the water of this dam constitutes a real health risk for users. Copyright © 2019 John Libbey Eurotext. Downloaded by ELSEVIER SCOPUS on 25/06/2019.
