Description
The Zeida Lead mine is located in the center of the High Moulouya basin, 26 km in the north of the town of Midelt (Morocco). During the period (1972-1985), it experienced very intense mining. However, this activity has had a harmful impact on the surrounding ecosystem through the storage quantities of several million tons of mining residues excessively loaded with heavy metals and Arsenic deposited without any adjusting, in dams on either side of the Moulouya River. Indeed, numerous research studies have focused on the contamination of surface water, soil, and pit lake sediments by heavy metals. This work aims to compile all the analytical data obtained in the various works in the form of databases under GIS (ArcGIS), in order to produce thematic maps of different chemical elements to determine the anomalous zones in heavy metals and Arsenic, compared with the references of standards used.
