Role of soil passage in removal of OMPs

During the infiltration of surface water in the dunes and along river banks, natural processes in the soil can effectively remove micropollutants. In surface water infiltration systems, the bottom sludge layer is…

Leaching of the geochemical buffer capacity in the subsurface

The geochemical buffer capacity of the subsurface assists in breaking down pollutants before they reach drinking water abstraction zones. But this involves the generation of reaction products that…

AquaNES

Water scarcity, excess water in cities and micro-pollutants in the water cycle are challenges for now and the future. In AquaNES, we test constructed Natural and Engineered Systems (cNES) to face these challenges, develop a monitoring programme…
