PhD in Fine Particles in Shallow Groundwater Systems

About the Role

Utrecht University is offering a fully funded four-year PhD position investigating the transport and fate of fine particles in shallow groundwater systems. The project addresses emerging concerns around microplastics, colloids, and fine mineral particles in groundwater, with implications for drinking water quality and ecosystem health. The deadline to apply is 21 June 2026.

The position is based in the Faculty of Geosciences, one of Utrecht University’s flagship research faculties with internationally recognised groups in hydrogeology, soil science, and environmental chemistry. Salary follows the Dutch CAO Universities scale for PhD candidates.

Responsibilities

• Conduct laboratory column experiments and field sampling campaigns to characterise fine particle transport in shallow aquifer systems
• Apply geochemical and physical modelling tools to understand particle-colloid interactions in groundwater
• Analyse particle size distributions, surface chemistry, and mobility under varying geochemical conditions
• Collaborate with water utilities, provincial authorities, and international research partners
• Publish findings in journals such as Water Research, Environmental Science and Technology, or Geophysical Research Letters
• Contribute to teaching by assisting in practical courses and supervising Bachelor’s thesis students

Requirements

• Master’s degree (or equivalent) in hydrogeology, environmental science, earth sciences, civil engineering, or a closely related field, completed before the start date
• Quantitative background including at least introductory knowledge of transport modelling
• Experience with laboratory or field water quality analysis
• Excellent written English
• Ability to work in a team and communicate findings to non-specialist audiences

Nice to Have

• Experience with particle characterisation methods (laser diffraction, electron microscopy, flow cytometry)
• Familiarity with geochemical modelling codes (PHREEQC, MINTEQ, or similar)
• Dutch language skills for field work and stakeholder communication
• Prior work on microplastics, colloids, or contaminant transport
