Pesticide Analytical (PESTAN) Model

PESTAN is used to estimate the vertical migration of dissolved organic solutes through the vadose zone to groundwater. Estimates are based on a closed-form analytical solution of the advective-dispersive-reactive transport equation. The model is intended for use in conducting initial screening assessments of the potential for contamination of ground-water from currently registered pesticides and those submitted for registration.
