Spatiotemporal dynamics of spring and stream water chemistry in a high-mountain area

► We use SOM approach to explore physiochemical data for mountain waters. ► Geologic structure and hydrological events impact water chemistry. ► Limited leaching, typical of crystalline core, reflects in low water mineralization. ► Sedimentary rocks are susceptible for leaching. ► Eutrophication has not been shown to be a threat in the Chochołowska Valley.
