EXAMS

Exposure Analysis Modeling System

The Exposure Analysis Modeling System (EXAMS) is built to support ecological risk assessment a predictive aquatic ecosystem model that evaluates pollutant fate and transport processes of synthetic organic chemicals, such as pesticides, industrial chemicals and leachates from disposal sites. EXAMS was developed by the US Environmental Protection Agency (US EPA).

Spatial Resolution
The spatial resolution is user defined by the defined system compartments and then split into grids.
Temporal Resolution
Steady state model option uses averages over time. Model can run dynamically to determine results at each specified time step ranging from hours to days.
Outputs
Outputs include water quality characteristics.
