Modeling has become a popular preliminary screening and predictive tool for assessing the environmental fate of agricultural chemicals. For modeling to be effective, realistic soil and climatic background inputs must be used. A procedure to quickly develop these environmental scenarios from readily available data sources for modeling leaching and dissipation is discussed, using the herbicide tridiphane as an example. Computerized soil survey information was used to identify soils most likely to be encountered in major use areas. A climatic model generated rainfall patterns for the study areas and provided the probability statement for the environmental assessment. Less than 5 man‐days of effort were required for the formulation of four realistic scenarios to use in the evaluation of the leaching and dissipation of tridiphane in key future markets.
