The paper examines groundwater from the area between the Siret and Moldova rivers. Data from 2021 and 2022 were used, taken from twelve monitoring wells. The main ions (Ca²⁺, Mg²⁺, Na⁺, K⁺, , Cl^-, , ) were checked with basic statistics, boxplots and the Piper and Schoeller-Berkaloff diagrams. The ion values from the two years stay close. The higher ones appear only in a few wells, and those places have local factors that influence the water. The meq·L^-1 values also fall in the same range in both years. Ca²⁺ and , remain dominant in all samples. The two diagrams place the water in the Ca–HCO₃ field, with no major change from one year to the next. There is no sign of a larger chemical shift in the aquifer, and the small differences stay local. The data show a stable aquifer, and these values can help when the area is checked again in the future.
