On 25th March 2020, the fieldwork for the rural case of the SUSPECt project started. At eight locations in the Barneveld area we placed passive samplers in the streams to investigate the presence of Veterinary Pharmaceuticals. At each location, one pair of samplers was kept for 12 weeks, whereas another pair was changed every 4 weeks. This has been done to explore the temporal distribution of measured quantities and to explore the influence of manure application and hydrological patterns. Fieldwork ended in June 2020, and first laboratory results were obtained in December same year. Presence of four targeted substance groups (antibiotics, antiparasitics, hormones and disinfectants) was confirmed.
