摘要：Huaibei is the important coal production base and electric power generation base, where groundwater is the primary water resource for drinking and irrigation. Thus, a comprehensive assessment of groundwater quality is critical for local residents. The hydrochemical characteristics of both shallow aquifer (14) and deep aquifer (11) were determined. The concentrations of the cations in the shallow groundwater decrease in the order of Na+ > Ca2+ > Mg2+ > K+, while in the deep groundwater in the order of Ca2+ > Na+ > Mg2+> K+, classifying both groundwater as Ca2+-Na+ type. The contents of anions in both shallow and deep groundwater follow a similar pattern as HCO3-> Cl- > S〇42- > N〇3-, with HC〇3- as the dominant species. The mean values of pH, electrical conductivity and total dissolved solid of shallow groundwater were higher than those in deep groundwater. Three groups of water were generated from hierarchical cluster analysis to test water quality data of their hydrochemical parameters. The factor analysis on different water quality parameters indicated that most of their variations can be explained by natural dissolved salts and anthropogenic activities. The assessment of water quality shows that deep groundwater is generally suitable for drinking and agricultural irrigation. In contrast, great caution should be taken when using shallow groundwater for irrigation or drinking. Appropriate technologies are thus required for shallow groundwater to reduce the salinity and sodium compounds before irrigation and to reduce F, Mn and total dissolved solid before drinking.
