Improving Environmental Fate Models for Agrochemicals Challenge Before making a pesticide or other agrochemical available on the marketplace, agrochemical companies need to fully understand the potential fate of the chemical in the environment. In the case of pesticides, the potential for the chemical to leech into groundwater is of particular concern. Currently, computer simulations utilizing data about soil characteristics and weather conditions at various locations are used to predict pesticide concentrations under different conditions. Lab data, including information about the rate of degradation and sorption properties, is used to build the computer models. However, inaccurate assumptions in the model will lead to incorrect conclusions about the environmental fate of the pesticide,
