Abstract
    In the sandy aquifers of the Netherlands brackish groundwater can be found even far inland. In the coastal region it may reach the surface. As the upper parts of these aquifers are of fluviatile origin, the salt must have been brought there afterwards. Existing theories about the transport mechanism do not always stand a critical review. The occurrence of brackish groundwater can only partly be explained by recent (Holocene) transgressions of the sea. In sea-covered areas chlorine ions are transported into the underground mainly by molecular diffusion. Another source is formed by the deep lying marine sediments of Earl Pleistocene and Tertiary Age. The salt may be transported upwards by hydrodynamical dispersion Brackish-groundwater bodies have changed after the creation of polders, which strongly influenced groundwater flow.
