About Anniek de Jong

Dr. Anniek de Jong is specialised in health-related water microbiology and works on the interface of microbial water quality, pathogens, antimicrobial resistance and waterborne exposure pathways under climate and land-use pressures. She works confidently with monitoring strategies, sampling designs, data interpretation and citizen science approaches. She particularly enjoys working on complex cases, where multiple disciplines, stakeholders and practical constraints come together. In her projects, she focuses on generating reliable microbial and chemical water-quality information and translating these findings into clear, evidence-based messages for partners, policymakers and the public. She supports co-creation by engaging stakeholders early, ensuring that scientific results become usable knowledge for healthier and more climate-resilient communities.

Her work contributes to several societal challenges: urban climate impacts on health, the health effects of floods, and increasing chemical pollution (with a focus on plastics), waterborne pathogens and antimicrobial resistance. Within Deltares, she contributes primarily to Moonshot 3, and supports Moonshots 1 and 2 in projects that address climate adaptation, water quality and health.

She works across projects such as:

• Momentum, Tulip, BlueAdapt: assessing microbial and pathogen-related health risks under climate change.
• Gloria-SWIM, SAMPAN: improving understanding of exposure pathways and microbial dynamics in urban water systems.

Anniek is also a member of the steering committee of AMR Global.
