Abstract
The paper focuses on the identification of hydrogeochemical processes in groundwater within the zone of influence of the Safonivske uranium deposit using the balance method and the determination of water types with the help of the Piper diagram. A total of 70 datasets on the chemical composition of water from the alluvial, aeolian-deluvial, Sarmatian, Pliocene and Kharkiv aquifers were considered. The average composition of groundwater was compared with the drinking water standards. For most wells, the water was found to be of a mixed type, but in some cases chloride and sulphate water was observed. Another characteristic feature is the balance between the following pairs of ions: sum of (Na+ + K+) and Cl−; sum of (Mg2+ + Ca2+) and sum of (SO4 2− + HCO3 −); Ca2+ and Mg2+. However, in some cases, direct ionic exchange between sodium and potassium, between calcium and magnesium is most likely to occur. According to drinking water standards, most of the groundwater within the zone of influence of the Safonivske uranium deposit is not suitable for human consumption without preliminary treatment.
