Short summary
Based on hydrochemical and isotopic analysis, we investigated the potential hydrogeological processes responsible for the increasing groundwater salinity in the coastal aquifer of Yang–Dai River coastal plain, northern China. Seawater intrusion is the major aspect and can be caused by vertical infiltration along the riverbed at the downstream areas, and lateral inflow into fresh aquifer. Geothermal water also makes a significant contribution to increasing the groundwater salinity.
