•Boron isotopes and carbamazepine contents were combined to assess groundwater contamination by effluents.•Carbamazepine contents ranged from 20 to 900ng/L in groundwaters mixed with treated wastewaters.•The chemical and isotopic data showed a high spatial and temporal variability.•The system is hig...
