Abstract

ISOTOPIC INVESTIGATION OF MINERAL WATERS OF IWONICZ-ZDRÓJ AND LUBATÓWKA

Abstract. Isotope studies are a very important supplement to various studies of the Iwonicz Anticline waters. Isotope studies of bicarbonate ion δ¹³C were conducted to prove the hypotheses about the origin of the waters. On the other hand, isotope methods with double markers (δ¹⁵N and δ¹⁸O in NO₃^- ion) were used to identify the origin of nitrates in the Iwonicz-Zdrój waters. Because nitrates from different sources have different isotope compositions, it is possible to test the quality of water and to identify alteration processes of nitrate compounds in the aquifer. For these purposes, the studies of nitrates isotope composition were conducted for the first time in selected waters of Podkarpackie Province. The authors have also identified reducing-oxidizing conditions in the aquifer because they influence hydrogeochemical processes and migration of elements.
