Short summary
After the Lushan earthquake, Ca2+, HCO3- and TDS of spring water increased significantly, which may be attributed to the enhanced interaction between water and carbonate rocks by the increment of dissolved CO2. Na+, Cl- and SO42- in water from Guanding, Zheduotang, Xinxing and Gonghe springs decreased, which may be related to the dilution of precipitation water. The increase in Na+ and SO42- in water from Erhaoying spring may result from a greater increase in sulfur-rich groundwater.
