To add new groundwater standard, 7 candidate materials (copper, zinc, selenium, manganese, iron, chromium, aluminum) were calculated by CROWN (Chemical Ranking Of groundwater pollutaNts). Copper and zinc were selected as groundwater candidates through the process and monitored total 430 samples for 2 years with 113 groundwater sampling sites. In this study, geological distribution characteristics (igneous rock, metamorphic rock, sedimentary rock) of copper and zinc were evaluated and the geological background levels obtained by a cumulative probability distribution and pre-selection methods were compared. In the results, the highest average concentrations of the copper and zinc were observed both in the igneous rock. The detection concentration ranges of copper and zinc in 430 groundwater samples were $0.002{ sim}0.931mg ;L^{-1}$ , and $0.002{ sim}32.293mg ;L^{-1}$ , respectively. In addition, detection concentration ranges of copper and zinc were $0.002{ sim}0.931mg ;L^{-1}$ , $0.002{ sim}32.293mg ;L^{-1}$ in the igneous rock, $0.002{ sim}0.134mg ;L^{-1}$ , $0.004{ sim}7.038mg ;L^{-1}$ in the metamorphic rock and $0.002{ sim}0.008mg ;L^{-1}$ , $0.003{ sim}3.948mg ;L^{-1}$ in the sedimentary rock, respectively. As a result of the background concentrations with two methods, zinc concentrations with the pre-selected method are comparatively higher than that of the others with the cumulative distribution. |
