Abstract—In order to understand the effect of ash-flushing water respectively. The groundwater samples were taken from civil

water in Baqiao power plant,xi’an is taken as a research object. and 90m. The positions of ash-flushing water
The domestic water consumption of people was affected directly were presented in table 1. The positions of
