Abstract The mine is situated in the East Algerian near the frontiers of Tunisia. The exploitation of iron is stopped until 1967.The water samples were collected from groundwater and surface water. Physicochemical parameters were measured during fieldwork. Water samples were analyzed for major ions and metallic trace element. We noted two aquifers, the first one is situated at 3 m under the soil, and it is connected with the Oued, and the second one is situated at 20 m deep. The water levels in the mine waste dump indicated the occurrence of a losing stream during the period of peak streamflow was a result of snowmelt runoff facilitates the displacement of pollutants. The analysis realized permitting to study the evolution of the MTE in the two aquifers. The electrical conductivity is very high near the mine. This situation explains the high concentrations of sulfate, chlorides, calcium, and sodium. The concentrations observed are generated by the phenomenon of dissolution of gypsiferous formations. The graphics realized shows hilt concentrations in the first aquifer, but in the deep, the concentrations become low. This repartition explains the retention of elements by the soil.

1 Introduction The impacts of base-metal mining activities on groundwater and surface water have been widely studied around the world [1]. Many observations reported that the deposits of slag heaps and mine waste around the mine are also a major source of contamination and are easily
