Distribution Characteristics and Quality Evaluation of Heavy Metals in Groundwater of Jixi Wetland

In this study, Jixi wetland in the west of Jinan was taken as the study area. The metal elements in 10 groundwater samples in this area were tested. The present situation of heavy metal pollution in the groundwater of Jixi Wetland was revealed by Kriging interpolation and single factor evaluation. The results showed that the average concentration of heavy metal elements in groundwater was Mn > Zn > Cu > Pb > Hg, and the maximum concentration of Mn elements in some areas exceeded the limits of relevant water quality standards in China. The results of factor pollution assessment showed that only Mn pollution in groundwater had appeared Class VI, and other heavy metal elements were within the safe range. From the point of view of environmental safety management, Mn, Hg and Cr in some groundwater in the wetland of West Jilin should be controlled to some extent.
