Popis: The contamination of Morocco’s water resources comes from three sources as like agriculture, industry, and urbanization. Within this project’s scope, we investigated groundwater contamination in the suburban community of Ain Zohra (located in the Mediterranean zone, Driouch province, eastern part of Morocco). The Zohra area is limited in east part by the rural municipality of Ain Zohra, in the north part by Driouch city and in the southern and western parts is bounded by the Boubker rural municipality. In July 2021, 21 samples were taken from the field (20 wells and 1 spring). In general, the results of this study showed that some water wells are highly mineralized as the conductivity is far above the drinking water standard. Every well’s pH is basic. Nitrate contamination in two places shows that the permeability of city soil affects the groundwater. The nitrate content might be higher than groundwater, which has 200 mg/l. In certain wells, groundwater contamination has raised organic matter levels above drinking water regulations. The water quality maps of some parameters were obtained based on application of Geographic Information System (GIS) for the study area.
