The occurrence of organic soil cover in river valleys is typical regions that were to areal deglaciation. This feature results from the adaptation of a series of linear depressions of glacial melt-out origin by rivers for their flow. Such a series of depressions, primarily composing overflow lakes, underwent subsequent infilling with mainly lake and marsh deposits. These very thick deposits, characterised by high sorption potential and developed in the form of continuous structures, can be considered as effective protection layers, isolating groundwater from contamination.
