A mathematical model predicts the likely concentrations of pesticides within specific catchments after taking into consideration rainfall, soil type, cropping, pesticide use, timing of application, and solubility. Once pesticides were identified, monitoring was undertaken by the NRA, where possible, to confirm the usefulness of the model predictions. The most important prediction from the model was that the herbicide bentazone would reach surface waters. 1 g l\. Consequently, the NRA informed 54 Impact of Agricultural Pesticides on Water Quality the water companies of the exceedences in rivers and advised them to monitor bentazone in drinking water supplies.
