  • 1. Pioneering research in the area concerned. So far, no work on this topic has been reported in the literature for this area of study.
  • 2. The results of the analysis carried out are relevant to the protection of groundwater, which is the main source of water supply in the area.
Aim of the study:
The aim of this study was to assess the impact of land development on the chemistry of groundwater captured in the Nowy Targ area.

Material and methods:
The scope of the study was to analyse the variation in chloride content and the magnitude of electrolytic conductivity over the years 2004–2016 for separate groups of wells in the city of Nowy Targ. Due to the significantly different usage of the land within which the groundwater intakes are located, a grouping of the groundwater intakes was introduced taking this factor into account. Physico-chemical analyses of the samples taken were carried out and archival data was already used. Non-parametric statistical tests such as the Kruskal-Wallis test and the median test were carried out to find statistically significant differences between chloride content and electrolytic conductivity magnitude between the selected groups of intakes.

Results and conclusions:
The results of the study and analysis of the literature showed that groundwater chemistry in the analysed wells depends on both natural factors and the nature of land use and the degree of urbanisation. The analyses concluded that land development has a dominant influence on water quality. The Orava-Nowy Targ Basin is a region where groundwater is characterised by a high susceptibility to contamination, and this susceptibility is due to hydrogeological conditions. The results of the tests showed statistically significant differences in chloride content and electrolytic conductivity values between the analysed groups of intakes. The lowest values of the analysed variables, were observed for intakes located in undeveloped areas, far from sources of anthropogenic pressure. Mean values of chloride and conductivity in this group of intakes were much lower than those observed for intakes located with the impact of a decommissioned landfill and for intakes located in built-up areas. Similarly, the average chloride and conductivity values were statistically different, although the differences between the intakes in the impact area of the decommissioned landfill and the intakes located in the built-up area were much lower compared to the chloride and conductivity values for the intakes located in the undeveloped area, which was also due to the location of these intakes in the area in question.
