GROUNDWATERS OF PIWNICZNA-SPA, THEIR AGES AND RECHARGE AREAS DEDUCED FROM ISOTOPE DATAAbstract. Therapeutical waters of the Piwniczna-Spa are of HCO3–Ca–Mg, HCO3–Ca–Mg–Na, HCO3–Mg–Na–Ca and HCO3–Na–Mg–Ca types, rich in CO2. In modern waters, Ca2+ dominates among cations whereas in older waters Na+ and Mg2+ dominate and mineralization is higher. Boundaries of the recharge areas were determined from the known geology and the mean elevation of recharge area estimated from the isotope data.
