Groundwater Vulnerability and Potentially Toxic Elements Associated with the Iron Mining District of Ouixane (Northeast of Morocco)

This study aims to investigate the groundwater vulnerability concerning potentially toxic elements in vicinity of abandoned iron mine Ouixane (Morocco). A modified DRASTIC method (DRSTI) is proposed with satisfactory results. High zones represent 40% area, while medium and low represent, respectively, 42% 18% area. These results have been validated by geochemical analyses carried out framework previous studies same Thus, superposition waste rock tailings map showed that latter located areas high therefore constitutes main cause deterioration quality groundwater. Otherwise, parameters significantly affect are: depth water (D), net recharge (R), unsaturated zone (I), other do not model used much influence on assessment. The allowed us locate most vulnerable metallic pollution resulting from Ouixane, it a tool for decision support developing effective action plans mitigate monitor effects transfer
