Ocena jakości wód źródlanych w rejonie Skrzycznego i Baraniej Góry

The study was carried out in the year 2009 on northern, southern and western slopes of Skrzyczne and Głębczański and Roztoczański stream catchments on Barania Góra in the Beskid Śląski Mountains. Water samples were collected from springs during snowmelt (May 1st−3rd). Data set consisting of conductivity, water pH, concentrations of major anions (Cl–, NO3–, SO42–), major cations (Na+, K+, Ca2+, Mg2+) and metals (Al, Fe, Mn, Zn) was produced. Waters were then classified according to Polish standards. Water class depended strongly on chemical composition of melting snow. It was found that water from most sampling points in springs was not potable – 39 out of collected 48 samples on Skrzyczne and 51 out of 57 samples collected on Barania Góra were beyond the first class according to Polish standard from the year 2008. The main reason for that was too low pH and high NO3– concentration. Chemical composition of spring waters depended also on plant cover and local properties of drainage areas. Statistically significant difference was observed between spruce and beech stands. Springs located in beech stands characterised higher concentrations of Ca2+, Mg2+, K+, Na+, SO42–, Cl– and higher PEW and additionally on Barania Góra higher pH as well. This dependence should be considered while planning stand composition in springs neighbourhood.
