The aim of the paper is to examine the variability of physical and chemical characteristics of two springs located in the Zagórzański Stream catchment (Spisko-Gubałowskie Foothills, Podhale region). Calcareous tufa occurs at one of the investigated springs. Field studies were conducted once a month from 25th March 2017 to 28thFebruary 2018. Water of the studied springs represents the bicarbonate-calcium-magnesium type during almost the whole year. The chemical composition of both springs is characterized by seasonal variability. The highest concentrations of most ions occurred in the summer, when the rainfall was the lowest and during winter drought; while the lowest concentration - in the period of increased rainfall. The variability of physical and chemical parameters of the spring with tufa is smaller than the other one. The spring with calcareous tufa stands out by the higher concentration of Mg2+ and SO42- and the presence of radon. The unique landscape values of the surroundings and hydrogeochemical features of the spring with calcareous tufa favour this place as an interesting hydro-tourism attraction in the Bukowina Tatrzańska region.
W artykule przedstawiono charakterystykę hydrograficzno-hydrochemiczną źródeł z wytraceniami martwic wapiennych położonych na obszarze Beskidu Małego. Źródła tego typu wraz z charakterystycznymi zbiorowiskami Cratoneurion commutati zaliczone zostały do siedlisk przyrodniczych o znaczeniu priorytetowym (kod Natura 2000: 7220). Wykazano, że depozycja martwic wapiennych zachodzi w źródłach o zróżnicowanej mineralizacji wód. Ma ona również charakter okresowy, przypada głównie na lato.

The paper presents hydrological-hydrochemical characteristics of springs with limestones precipitations situated in the area of the Beskid Mały Mts. These springs with characteristic plant communities Cratoneurion commutati were included to priority NATURA 2000 habitat (code 7220). It was revealed that precipitation of limestone occurs in spring with diversified mineralization of waters. It is a periodic phenomenon with the maximum of the occurrence in summer.
