A model for managing the impact of pesticide on groundwater at multiple geographical scales : watershed to soil profile / by A.S. Crowe & W.G. Booty. : En13-5/95-196E-PDF

"The multi-level pesticide assessment methodology developed here permits regulatory personnel to undertake a variety of assessments on the potential for groundwater contamination from pesticides in agricultural areas at an increasingly detailed geographical scale of investigation. This approach accounts for a variety of assessment objectives, geographical scales, restrictions on the availability and accuracy of data, time available to undertake the assessment, and the expertise of the decision maker. The Level 1: regional scale ranks the relative potential for groundwater contamination among several districts. The Level 2: local scale assesses the potential for groundwater contamination of soils within a district at a soil polygon scale. A Level 3: soil profile scale allows the user to simulate the migration of a pesticide within a specific soil profile, and to determine the extent and timing of leaching of the pesticide. The system developed here integrates, GIS, data bases, data management systems, knowledge-based systems, and pesticide assessment models"--Abstract.
