Study design

Details on sampling:
- Geographic coordinates: the different waterworks involved in the water treatment process of the Ruhr megalopolis
- Known emission sources near sampling site: Ruhr basin
- Period of sampling: not reported
- Sampling: samples were collected at points used for routine monitoring. The sample does not exceed 2 L which is further split into two 1-L samples in order to carry out the extraction in duplicates
- Sample storage before analysis: samples were stored in glass bottles at 4°C for a maximum duration of 48h
