Abstract: To assess the risk of groundwater environment in Feicheng of Tai’an City, 77 samples were collected to analyze 12 heavy metals (metalloids) and pH in the groundwater according to the griding sampling method. The results showed that As and Cr(VI) were not detected, while the other 10 heavy metals were detected with different detection frequencies. The order of average concentrations for these 10 heavy metals in groundwater in the study area is: Fe＞Mn＞Zn＞Ni＞Cu＞Pb＞＞Sr＞Co＞Cd＞Hg. The concentrations of Fe and Me ranged from 138.47 to 2187.81 μg/L and 0.45 to 135.68 μg/L, respectively, with the average concentrations of 857.41 μg/L and 13.9 μg/L. Results from single factor index and comprehensive pollution index evaluation methods indicated that the main heavy metals affecting groundwater quality in the study area were Fe, Pb, Zn, and Mn. Fe concentrations from 94.81% of groundwater sampling sites have exceeded the Class Ⅲ limit for groundwater quality standard (GB14848−2017). Fe, Mn, Co and Ni were derived from geological origins, Pb and Cd are derived from transportation and industrial origins, and Cu and Zn are derived from agricultural origins. The health risk of heavy metals in the groundwater was relatively low, and the non-carcinogenic risk caused by drinking water is the main pathway for groundwater in the study area. The order of health risk values is Fe＞Pb＞Mn＞Co＞Cu＞Zn＞Ni＞Hg, and Fe were the main contributor to non-carcinogenic health risks.
