The aim of this study was to verify a hypothesis about the differences in chemical composition of spring waters as determined by hypsometric factors (relief) in the Tatra Mountains. During our research, 1,505 hydrological objects were inventoried, but this research was conducted on 872 selected outflows (swamps and springs). Temperature, conductivity, and pH were measured together with discharge in the field. A 0.5 dm³ water sample was taken from each hydrological object. The chemical composition was determined by ion chromatography. The role of hypsometric factors in the formation of chemical composition of spring waters is reflected throughout the TNP as a systematic reduction of the importance of two major hydrochemical classes of spring waters (HCO₃-Ca, HCO₃-Ca-Mg) in favor of waters containing a large share of SO₄²⁻. The lower and ridge parts of the mountains are characterized by low hydrochemical diversity for the entire Tatra range.

The study focused on the effects of deforestation by heavy winds and tree stand damage produced by bark beetle invasion on water chemistry of mountainous catchment of Kościeliski Stream in the Tatra National Park (southern Poland). 200 samples of stream and spring water were collected in three series: in July, August and October 2015. Water samples obtained from areas characterized by tree stand damage caused by heavy winds were found to have much higher mean concentration of nitrate (15.44 mg/L) as well as a much higher overall mean nitrate content (3.44% mval/L) than samples obtained from non−deforested areas (3.26 mg/L and 0.78% mval/L). The increase in nitrate concentration and its share in overall water chemistry was high enough that the anion sequence for the deforested areas became altered from HCO3>SO4>NO3>Cl to HCO3>NO3>SO4>Cl. The mean change in water nitrate concentration in areas with tree stands damaged by the bark beetle was smaller (6.17 mg/L; 1.60% mval/L) than that for areas deforested by wind. The concentration of NO3– in stream water in deforested areas varied more than that in stream water in non−deforested areas.
