Baltic coast - Opis:
- The paper presents comprehensive results of the hydrogeochemical and isotope analysis of waters in terms of their genesis and “ages”. Mostly chloride anomalies were found on the Polish Baltic coast. The processes of ascension and ingression of saline and brackish waters are the main reasons for their development. The water exchange rate was determined in each aquifer systems within the study area the results of isotope analysis, the concentrations of 4He and 3H. A significant contribution of infiltrating waters in cold climate is apparent in samples taken from: Ustka, Jarosławiec and Dąbki, for which NGT values range from 4.3 to 5.2°C. Waters with this genesis are found mainly in deep Pleistocene aquifers and Cretaceous roof layers. Changes in the chemical composition of waters in this area are strongly affected by human activity consisting in excessive exploitation of aquifers (mainly in the 1970s and 1980s). The process of saline water penetration into exploited aquifers was most extensive at that time. At present, it has been significantly inhibited as a result of reduced water extraction at the water intakes in this area. New water intakes are located at a considerable distance from the areas threatened with ingression or ascension of brine and saline water.
