Geology and Land-use related pattern of spring water quality. Case study from the catchments of the Malopolska Upland (S. Poland)

Janusz Siwek, Wojciech Chelmicki


Spring water chemical composition was investigated in three catchments (i.e. Pradnik, Dlubnia and Szreniawa) located within a carbonate-rock monocline from the Upper Jurassic and Cretaceous periods and constituting voluminous aquifers. The total spring water dissolved solids (TDS) displayed a concentration increase between 1974 and 1999. Using principal component analysis (PCA), the authors identified factors determining spring water chemistry. The research focused on making a distinction between the regional (large-area) and the local factors, the latter being related to the land-use in the direct vicinity of the springs. PCA yielded evidence that local sources of pollution can significantly contribute to the differentiation of spring-water chemical composition.
