Water wells are used for drinking and irrigation. But the geological nature of the soil in any region promote metal contamination by the metallic trace elements such as manganese, nickel, lead, chromium and cadmium found in that region. Tyikomiyne is located in the east of morocco. An assessment of the water quality of the wells in Tyikomiyne was carried out to determine the environmental impact of these trace elements, the spatial variation of water contents of trace metals manganese, nickel, lead, chromium and cadmium were studied during low water level of the five wells, Faryat (Wells 1), El Masjid (Wells 2), Hadi (Wells 3), Hilla (Wells 4), and Deppiz (Wells 5). in the area of Tiykomiyne region Talsint. A complete diagnosis of the current situation of the metal pollution and rigorous monitoring of its evolution were studied to judge the quality of the water and its impact on the environment. The analysis results show that the concentrations of metallic elements studied (except lead) analyzed during low water are well below the norms fixed for power and irrigation. By against lead levels, exceed the standard for potability in all measurement points, but they remain below the standard set for irrigation. The high levels of lead found can be explained by the regional geological context. At the end of this study, it was concluded that the use of the Tiykomiyne wells water without treatment could be a significant health risk.
