Nabeul, Tunisia

The aquifers, located in the Cap Bon Peninsula in Tunisia, are strongly overexploited due to increasing water demand for domestic use and irrigation. The groundwater level is rapidly declining and water quality is deteriorating due to seawater intrusion and diffuse pollution from agriculture (pesticides, fertilizers). In response, the local basin authority started the Managed Aquifer Recharge fed with treated wastewater, using infiltration basins. However, treated wastewater is polluted by high salinity and micropollutants. There is thus a strong need to implement an effective tertiary treatment to minimize the introduction of these pollutants in the aquifer.
