ABSTRACT
The area of Oued Souhil, located in north of Tunisia, is irrigated with treated wastewater (TWW) for over 40 years. The objectives of this study were to investigate the state of the hydro-chemical characteristics and the heavy metals content and their spatial variability. Water samples from two locations (A: downstream of Oued Souhil perimeter; B: out of Oued Souhil perimeter) have been collected September 2022, which correspond to the post-irrigation period. Water samples were analyzed for major ions (Na, K, Ca and Mg) as well as the trace elements (Cu, Zn, Fe and Mn). Overall, the water from both sampling locations is characterized by abundance of Na ions reaching 673 and 582 ppm in A and B, respectively. In contrast, Ca and K registered higher amounts in groundwater from location A with 77 and 150%, respectively. In addition, the spatial distribution of Ca, Mg and Na was similar. Thus, the mineral content of the groundwater is controlled by two factors: treated wastewater irrigation and seawater intrusion. Data revealed that trace element (Cu, Zn, Fe, Mn) concentrations did not exceed Tunisian standards. The spatial distribution of these elements was different.
