Abstract: Through sampling and monitoring of groundwater in a study area of Shandong Province in 2022, the data were analyzed to evaluate the environmental quality of groundwater in the study area. First, Surfer and ArcGIS were used to interpolate the over standard indicators, and the distribution rules of different over standard indicators were obtained, and the reasons were analyzed. Then, SPSS software was adopted to conduct correlation analysis of the over standard indicators to explore the internal correlation of the factors. Finally, according to the results of groundwater evaluation, some specific suggestions were put forward to provide the basis for regional groundwater management.
