Three factors make analyzing pollutant fluxes in sewers a fascinating topic: 1) Wastewater is one of the most information-rich waste streams of our society; 2) The spatiotemporal variability of (micro‑)pollutant fluxes in sewers can be high and is typically difficult to predict; 3) Sewers are reactors in which pollutants can be subject to transformation. Numerous research questions require samples from sewers and proving representativeness can be challenging. Therefore, we develop experimental and statistical methods to reliably quantify, evaluate and interpret micropollutant fluxes. Examples of applications are the quantification of pharmaceutical loads in hospital wastewater, the estimation of illicit drug consumption (sewage-based epidemiology), novel sampling methods to improve the predictability of pollutant fluxes in stormwater overflows or assessing sewers’ capacities to transform certain compounds.
