EPA Center for Exposure Assessment Modeling (CEAM)
Groundwater Models
- Quantifies the movement of subsurface water
- Provide inputs to subsurface contaminant transport models
Surface Water Models
- Models contaminant movement and concentration in lakes, streams, estuaries, and marine environments
Food Chain Models
- Provides tools for tracking the movement of contaminants through food chains and for estimating chemical impacts on exposed biota
Multimedia Models
- Quantifies the impacts of contaminants as they travel through more than one of these environments
TMDL Models and Tools
- Facilitates the development and implementation of Total Maximum Daily Loads(TMDLs)
- Includes enhancements, complex models like HSPF, and simple data-driven models like load duration curves (LDCs)
