Abstract:: The earthquake occurred in Sichuan province on May 12, 2008 was China’s most devastating earthquake since the 1976 Tangshan earthquake catastrophe. The most immediate concerns after the disaster are human casualties, injury and property destruction. Water environment problems induced by the earthquake for human health and economic development are one of the primary concerns before the reconstruction after the disaster. Water was sampled in the earthquake-affected area in June, 2008 for detecting the ion concentration. The results of 66 water samples show that the cations concentration character is Ca²⁺>Mg²⁺> Na⁺> K⁺, while the anions’ is SO₄^2->NO₃^->Cl^-> PO₄^3-. The highest concentration of Ca²⁺ is in the wells while the lowest concentration of PO₄^3- in all samples. PO₄^3- is not detected in the 16 of 66 samples. All ions except PO₄^3- concentration is the highest in the well. Ca²⁺, Na⁺, Cl^- in the ground fissures is higher than other regions except wells. The Na/Ca ratio fluctuates at 0.106 in the all sampling areas.
