Abstract:In order to understand the hydro-chemical characteristics and water quality of groundwater in Xiongxian area,43 groups of groundwater were selected and determined by the method of instrument analysis and volumetric method. the main ionic characteristics of groundwater in Xiong County were analyzed, and the quality of groundwater was evaluated by comprehensive evaluation method. The results showed that: ①The detection limit of the method was 0.001 ~1.3 mg/L;②pH and metasilicate acid had the lowest spatial variation (CV<30%) ; Magnesium chloride and iodide had the highest spatial variability (CV>100%);③Hydro-chemical types was mainly HCO3--Na+;④The results of water quality evaluation show that the groundwater quality was well in the study area, mostly II water and III water.
