Study of groundwater pollution of irrigated Ain Zohra commune (North-eastern Morocco) by nitrates using GIS. Understanding the Climate–Water–Energy–Food Nexus and the Transition Towards a Circular Economy: The Case of Morocco

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