Groundwater vulnerability map: the Naturally Salted Zones

The map of the vulnerability of the groundwater of the Flemish Region can be defined as a map of the level of risk of contamination of the groundwater in the upper water layer by substances penetrating the ground from the soil, taking into account only static parameters. This map can later serve as a basis for a more detailed map, which can also include dynamic and hydrochemical factors. However, where the top recoverable aquifer is naturally salinized (>>The naturally salinized zones This layer shows the zones where the groundwater in the first aquifer is naturally salinized.
