Abstract

Abstract

The hydro geochemical research into the karst water of Niangziguan spring area indicates the gradual decrease both in the concentration of sulfate and in the mineralization degree, but the gradual increase in the ratios between Ca²⁺, Mg²⁺ and SO₄^2- along the flow path. The hydro geochemical modeling shows that the widely dissolving of gypsum causes the high concentration of gypsum from recharge area to discharge area, and even at the shallow aquifer. In addition, the mixing with deep water and sidewise water from the runoff to the discharge area reduces the concentration of sulfate in the water. The extraordinarily high concentration of sulfate was initiated by the pollution by the seepage from the Carboniferous-Permian where the oxidation of sulfide produced much higher sulfate in the Middle Ordovician aquifer. The water from the Lower Ordovician aquifer would be much better.
