| Summary: | River estuaries are peculiar areas from the point of view of their groundwater origins, frequently connected with the diversification of groundwater chemistry. In the area of the Vistula delta in a number of places, the increased concentration of chloride and fluoride ions has occurred (Kozerski et al. 1987). These issues have already been considered in the studies of Kozerski (1981), Kozerski and Kwaterkiewicz (1984, 1988). The origin of salt and brackish water in the area of Żuławy was already the subject of scientific research in the 1930s (Schroeder 1931), and subsequently continued by Sadurski (1985, 1989), Burzyński and Sadurski (1989), Zuber at al. (1990, 2000) and Krawiec (2013).
