Currently, EXPRES contains two mathematically-based pesticide models, PRZM and LEACHM, which can be used to provide a detailed analysis of the migration and transformation of pesticides leaching through the unsaturated zone to the water table. The new model, known as the LP/LI screening model, is designed to provide a relative (with respect to other pesticides) assessment of the potential for a pesticide to leach to the water table"--Management perspective.
