PWC using the PRZM
Pesticide in Water Calculator using the Pesticide Root Zone Model
The Pesticide in Water Calculator (PWC) and Pesticide Root Zone Model (PRZM3) are pesticide transport and watershed model for agricultural systems. The model captures runoff and erosion processes, and pesticide processes including transport through surface and groundwater, degradation kinetics, and transformation to daughter compounds.

- Model Information
- For more information about this model, go to www.epa.gov
- Spatial Resolution
- Within the watershed area, each waterbody is modeled as a discrete unit, and uniform parameters are used.
- Temporal Resolution
- Simulation duration can extend over years. Inputs data sets are entered in daily time steps.
- Outputs
- Outputs include pesticide and pesticide derivative compound concentrations in surface waters and groundwater sources.
