This paper presents the results of an isotopic study of spring waters in Swietokrzyski (Holy Cross Mountain) National Park (SNP), south-central Poland. The delta(SV)-S-34-CDT and delta(OV)-O-18-SMOW of soluble sulfates (n = 40) varied from 0.5 parts per thousand to 18.1 parts per thousand and from 3.5 parts per thousand to 12.2 parts per thousand, respectively. The average delta S-34 values are closely similar to those of rainwater, soils and rocks (comprising scattered pyrite). This suggests that soluble sulfates in the springs originated from mixing of recent and historic deposition, sulfates derived from pyrite oxidation, and CS-mineralization in soils and debris. An additional anthropogenic sulfur input (inorganic fertilizer) occurs in the water of spring S-61 located in the Swietokrzyski National Park buffer zone. The delta(OV)-O-18-SMOW of spring waters (n = 4) were in the range of -10.6 parts per thousand to -10.2 parts per thousand indicating that they are derived from vadose groundwater in SNP. This was the first isotope study of spring waters in the national parks of Poland. It enabled the determination of sulfur pathways and discrimination between natural and anthropogenic sources of this element in a relatively pristine area.
