What is it about?
The availability of clean water is at risk across the globe. Water pollution poses a threat to ecosystems and society. A multi-pollutant modelling approach can help to better understand and manage water quality issues. We develop multi-pollutant models of causes, effects and solutions of future water stress, while accounting for water demand, water availability, and pollution in rivers, lakes, reservoirs and coastal seas. Many pollutants have common sources and multiple impacts. A new generation of models is needed to explicitly address the combined exposure of surface waters to multiple pollutants. Such models could serve as a basis for integrated water quantity and water quality assessments. In Wageningen, we co-develop such models, focusing on water quantity (the VIC model) and water quality (nutrients, pathogens, plastic, salinity, toxic chemicals, etcetera). We develop global models, but apply them on multiple scales.
