The results show that when the depth gradually reduces, pH values gradually increase, but conductivities and (superscript – subscript 3) content gradually reduce. There are also obvious differences between the groundwater in loess, alluvial deposit and acidity rock in the south of Chang'an, which relates to the depth, the characters of loess, the lixiviation and the evaporation. The element content of groundwater is high in the loess tableland, so it's fitter for drinking than the groundwater in the Cuihua mountains, which is of acidity and low element content.
