Johan van Leeuwen

Dr. Johan van Leeuwen is a Researcher at Utrecht University's Hydrogeology group within the College of Geosciences. His work focuses on contaminated subsurface remediation, wastewater treatment, and sustainable green technologies. He holds dual roles as a senior researcher at KWR Water Research Institute and project leader for an NWO-funded initiative under the 'PtS - Water, Climate and Future Deltas' theme.

Education:

• PhD in Environmental Science (2021), Utrecht University

Research Interests: Johan integrates biochemical, geochemical, and hydrogeological processes to develop carbon-neutral remediation solutions. Current projects include:

• PFAS and microplastics behavior in subsurface environments
• Two-phase flow phenomena (e.g., water-DNAPL/gas systems)
• Biodegradation of emerging contaminants like PFOS/PFOA
• Green applications such as wind-powered wetlands and solar soil warming

Grants & Projects:

• NWO grant for contaminant remediation research (2020–present)
• Leadership in pilot-scale trials for novel treatment technologies
