Department Water Resources and Drinking Water
Chemistry of Water Resources
We study basic biogeochemical processes that influence the quality of water resources, with a focus on inorganic contaminants.
While our main interest is groundwater, we include the adjacent river, lake and soil systems and we are involved in the national river monitoring and survey programme (NADUF).
In connection with increasing water contaminant problems in developing countries, we work on the development of adapted water treatment procedures for the removal of contaminants, in cooperation with the drinking water group and EAWAG's SANDEC department.
We take the approach of studying key processes in water resources in detail with model systems in the laboratory. The aim is to obtain a general molecular level understanding of the most important reactions that can be applied to more complicated environmental systems and to the development of remediation strategies and water treatment options.
