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.
