Features of chemical composition of groundwater and surface water of the Crimean training ground, Faculty of Geology, SPSU

Fresh groundwater oí the Quaternary aquiler and zones of exogenic fracturing of bedrock are well developed within the Crimean training ground. Formation of groundwater and surface water is caused by the infiltration of precipitation. The predominant ions of all natural waters are mostly HCO ₃^- (or sometimes SO₄^2-), Ca ²⁺ and Mg₂⁺. Among the trace elements, higher contents of Sr and Ba in surface and groundwater have been revealed, higher contents of V are observed in interstitial waters of the volcano-sedimentary deposits; higher contents of Ag, Cu, Zn, Fe, Mn, Cr in some water bodies are probably caused by human impact. There are point sources of sustainable nitrate pollution located in the center of the village Trudolyubovka. Concentration factors and coefficients of water migration of chemical elements have been calculated.
