TL;DR: In this article, the pesticide root zone model (PRZM) was developed to evaluate pesticide leaching threats to ground water for different crops under varying climatic conditions, soil characteristics and cropping practices.

TL;DR: In this article, a procedure is described for making regional assessments of pesticide residue loadings and movement in groundwater underneath and downgradient from treated fields using a Monte-Carlo numerical simulation technique.

TL;DR: In this article, the environmental fate and migration of pesticides applied to croplands as they are affected by conservation tillage practices, pesticide models for leaching, surface water and ground water were selected and an application method was developed.

TL;DR: In this article, a method is presented for estimating the number of samples needed to evaluate pesticide leaching threats to ground water at a desired level of precision, based on desired precision (exhibited as relative tolerable error), level of confidence (90 or 95%) and estimates of variability (expressed as the coefficient of variation) for selected pesticide and soil characteristics.

TL;DR: In this article, the authors identify and discuss three components (i.e., management mechanism, environmental investigation approaches, and environmental assessment and criteria) for establishing a management framework for nonpoint source pollution control.
