摘要
Ten indicators including Fe, Mn, total hardness, NO-2, NH+4, Cl-, F-, C6H5OH, Ba, Be were selected as proxies for the quality of shallow groundwater in Liaoning central area. The groundwater quality was calculated according to national standards by the fuzzy comprehensive evaluation method. The integration of environmental quality characterized by high content of iron and manganese ions is poor and most of the water cannot be used directly as drinking water. The growing need to perform quality evaluation of groundwater makes this method both important and prominent and provides scientific data for water resources protection and planning.
