Research data for Using a combination of δ13C-difference in dissolved carbon, δ2H, and δ18O to localize leachate leaks at landfill sites in China

This dataset is collected from twelve published landfill cases in different countries around the world. 380 data points are included in this dataset, and information on the stable isotopes (δ2H, δ13CDIC, δ13CDOC, and δ18O), concentrations of common contamination indicators (TDS, COD, and NH), hydrological parameters (e.g., ORP) of groundwater and leachate, and sampling background information are the collected parameters. All the data are collected from points located less than 1000 m from the landfill boundary, so that the detected hydrochemical information is highly correlated with the landfills.

本数据集采集自全球不同国家的12个已公开垃圾填埋场案例，共包含380组数据样本。本次采集的参数涵盖地下水与渗滤液的稳定同位素（δ2H、δ13CDIC、δ13CDOC及δ18O）、常见污染指标（总溶解固体（TDS）、化学需氧量（COD）、NH）浓度、水文参数（如氧化还原电位（ORP）），以及采样背景信息。所有数据的采样点均距离垃圾填埋场边界不足1000米，因此所检测到的水文地球化学信息与对应填埋场具有高度相关性。
