Profile

Jan Willem Foppen (1965) received his M.Sc. degree in Hydrogeology from the VU University in Amsterdam in 1990. He worked for Natuurmonumenten, Dienst Grondwaterverkenning TNO, the Institute of Applied Geosciences of TNO, and since 1998 for IHE Delft. Since the beginning of 2021, Foppen is working 1 day per week at the TU Delft.

Intrigued by poor groundwater health conditions in various developing countries, Foppen focused on the transport of the fecal indicator organism Escherichia coli in saturated porous media, whereby the aim was to extend the colloid filtration theory. Over the years, his interest focused more on the transport of colloids in groundwater and surface waters.

Since 2016, he worked on silica DNA tracers. In search of new tracer substances to identify hydrologic processes, Foppen and his team used synthetic DNA in groundwater and surface water injection experiments. Synthetic DNA is a small piece of 'organic matter', 100% natural, and completely harmless. Detection of these synthetic DNA molecules is carried out by the polymerase chain reaction (PCR), a method widely used in molecular microbiology, biomedical research, forensic diagnostics, etc.

Besides the transport of bacteria and silica DNA tracers, his research interests include water and sanitation in slums in Sub-Saharan Africa.
