The purpose of the research wasto examine how factors such as land use and land management affect the quality ofgro- undwater and surface water. These studies werepossible thanks to funding from the IDUB Technetium Talent Management Grantsproject titled“Assessment of Anthropogenic Threat to Groundwater and Surface Water in the Region of the Vistula Lagoon”. The research area included a section of the Vistula Spit, Żuławy Wielkie and the coastal waters of the Vistula Lagoon. Field studies were conducted during three field trips; 15 groundwater points and35 surface water points were examined. During these studies parameters such as temperature, pH, electrical conductivity, and the content of nitrogen, nitrates, phosphates, and sulfates were measured. In the Żuławy area it was found that surface water and groundwater are under the direct influence of the Vistula Lagoon, causing their salinity increase. Locally, man-induced chemical changes are also visible. The inflow of nutrients from fertilization of agricultural fields and uncontrolled discharge of wastes into drainage canals have been observed. The local anthropogenic impact on the water environment was also found in the Vistula Spit area. It was caused by pollutions from tourist facilities.

Badania hydrogeologiczne Żuław Wielkich koncentrują się na zasoleniu wód podziemnych. Od początku XX wieku do chwili obecnej obserwuje się wysokie stężenia chlorków, jonów amonowych i mineralizacji we wszystkich poziomach wodonośnych. Uznaje się, iż na przeważającym obszarze nie występują tu warstwy wodonośne o znaczeniu użytkowym, a zasoby wód podziemnych Żuław Wielkich są ograniczone. Przeprowadzone badania pozwoliły na ustalenie genezy występujących problemów z jakością wód podziemnych i powiązanie ich z warunkami hydrogeologicznymi regionu.

The hydro-geological research in the Żuławy Wielkie region is focused on the groundwater salinity. Since the beginning of the 20th century, we have been observing high concentration of chlorides, ammonium ions and mineralisation in all water-bearing strata. It is considered that in the major part of this area there are no functional water-bearing strata and groundwater resources of Żuławy Wielkie are limited. The performed research allowed for determination of the origin of the existing issues related to the groundwater quality, linking them to the hydro-geological conditions of the region.

This study presents preliminary results of investigation of groundwater chemical composition (major ions, nitrogen and phosphorus compounds) in a coastal multi-aquifer groundwater system in the Puck Municipality. It was found that the groundwater composition is specific for each aquifer and shows some local variation. There is also a clear vertical geochemical inversion within the aquifers, with the highest concentrations of dissolved components in the shallowest aquifer. In general, all of the aquifers represent groundwater quality classes I, II and III, which can be evaluated as good quality according to Polish environmental law. An increase in the concentrations of principal pollution indicators over time has been observed only in the shallow aquifer. Distribution of basic pollution indicators in the groundwater implies a local impact of agriculture, as well as an influence of municipal wastes from households and farms. Poor sanitary conditions of farms, animal husbandry, storage and distribution of organic fertilizers (e.g. manure) can be potential sources of contamination. However, concentrations of contaminants in the coastal zone of aquifers discharging to the Bay of Puck are within the range for quality classes I and II, and generally lower than the concentrations measured in seawater, which suggests limited impact of the terrestrial groundwater discharge on the Bay of Puck contamination.
