- Remarks on result:
- other: Capita load, calculated as the mean of the effluent values of ten WWTPs.
- Country:
- Switzerland
- Location:
- River Glatt at its source (Lake Greifensee)
- Substance or metabolite:
- substance
- Conc.:
- 2.8 µg/L
- Country:
- Switzerland
- Location:
- River Glatt at its outlet to the river Rhine
- Substance or metabolite:
- substance
- Conc.:
- 6.9 µg/L
- Remarks on result:
- other: Between the source and the outlet of the river Glatt, on a distance of about 35 km, wastewater from 7 additional wastewater treatment plants is discharged.
- Country:

- Location:
- Groundwater sample taken from the river Glatt at its outlet to the river Rhine (km 35)
- Substance or metabolite:
- substance
- Conc.:
- 4.7 µg/L
- Remarks on result:
- other: Waste water of seven treatment plants was discharged between the source an the outlet of the river, resulting in a waste water burden of 100% at this sampling point.

- Substance or metabolite:
- substance
- Conc.:
- 2.6 µg/L
- Remarks on result:
- other: Tap water sample (raw drinking water) taken from the lower Glatt valley. The highest concentrations of acesulfam K in the groundwater were observed here.

Applicant's summary and conclusion
- Conclusions:
- Based on its persistence, its ubiquitous occurence in the environment, and its easy analytical detectability, the authors concluded that acesulfame K is an ideal marker to reflect a contamination of surface water and groundwater with domestic wastewater.
