The water supply of the eastern part of the Uznam Island comes from two groundwater intakes: Zachód and Wydrzany. The threat to the resources part of the groundwater intake Wydrzany approach results from the progressive concentration of chloride ion, mainly in the southern part of the intake and locally in the central part of the water intake. After the launch of the intake at the end of the 1970s, the development of the water table depression, currently reaching the shore of the Lagoon, caused the frontal infiltration of the brackish waters of the Szczecin Lagoon into aquifers and a small amount of brine ascesion from the mesozoic strata. To determine the genesis of salinity, isotopic tests were carried out, including 37Cl chlorine isotopes. Water for the Szczecin Lagoon and groundwater, including the aquifer of the Cretceous, have been sampled.
