In the Netherlands, approximately two-thirds of the drinking water is produced from groundwater. Due to the filtering capacity of the underground, the quality of groundwater is high compared to surface water. However, the quality and availability of groundwater are threatened by the emission of highly mobile organic micropollutants such as pesticides and pharmaceuticals.
Additionally, freshwater aquifers near the coast face pressure from saltwater intrusion, while increased drainage and prolonged droughts reduce natural aquifer recharge. The Groundwater technology theme develops tools to address these challenges. These include enhancing natural pollutant attenuation, distributed groundwater flow & quality sensing, and underground infrastructure such as wells and dams. The theme started in 2008.
