On Thursday 19 September, the fieldwork for the urban case of the SUSPECt project started. At four locations throughout Nijmegen we placed small sponges (passive samplers) in the sewer to assess the CEC composition of different wastewater types (domestic, industrial, surface run-off). These sponges remain in the underworld for one to 6 weeks until we retrieve them again and take them to the laboratory for further analysis. We expect to obtain the first results in November.
