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.
