Estimating potential groundwater contribution of nickel, copper, cadmium, lead, and zinc concentrations to surface water catchments in Denmark

This dataset includes estimates of the typical groundwater contribution of nickel, copper, cadmium, lead, and zinc to the ID15 catchments. The methodology is described in detail and illustrated for nickel (see pdf file). The data is provided as a shapefile and csv file. This work was funded by the Danish EPA (Miljøstyrelsen) in relation to \"Videreudvikling og klargøring af MetalStat for landsdækkende beregninger.\" (Sørensen et al., 2024) and \"Unifying monitoring and modelling of water concentration levels in surface waters (Version 2)\" (Sorensen et al., 2025).

本数据集涵盖镍、铜、镉、铅及锌对ID15集水区的典型地下水贡献量估算结果。相关方法学已针对镍元素展开详细阐述并辅以示例说明（详见PDF文件）。数据集以形状文件（shapefile）与逗号分隔值文件（CSV）格式提供。本研究由丹麦环境署（Danish EPA，Miljøstyrelsen）资助，关联两项科研项目：其一为《面向全域计算的MetalStat迭代开发与完善》（原文："Videreudvikling og klargøring af MetalStat for landsdækkende beregninger"）（Sørensen等，2024）；其二为《地表水水质浓度监测与建模统一方法（版本2）》（Sorensen等，2025）。
