About
Understanding global contaminant fate modeling
The HydroFATE Model
HydroFATE is a global contaminant fate model designed to track and predict the movement of chemical compounds through freshwater systems worldwide. The model integrates hydrological data, chemical properties, and environmental factors to provide comprehensive insights into contaminant distribution and concentration patterns across global river networks.
The HydroFATE map application
This interactive map application showcases the capabilities of HydroFATE using insights from a study on the environmental exposure of antibiotics in the global river system. It examines various scenarios by adjusting key parameters and configurations, building on the study's baseline analysis of the 40 most-consumed antibiotics in global river networks.
The content is based on the study: Antibiotics in the Global River System Arising from Human Consumption. Ehalt Macedo, H., Lehner, B., Nicell, J., Khan, U. & Klein, E. PNAS Nexus (2025).
The visualization tools help identify hotspots of antibiotic pollution and potential areas of concern for antimicrobial resistance development. Users can explore antibiotic concentrations and risk quotients across the global river network, select specific antibiotics, adjust thresholds, and view detailed information about individual river segments.
