Modelling regional transport of pesticide residues in groundwater

    Research output: Chapter in Book/Report/Conference proceedingChapter


    The movement of pesticides through soil and groundwater to pumping wells for drinking-water supply was modelled. Most of the retardation and transformation occurs when a pesticide moves through the unsaturated zone. Computed leaching to groundwater increased when soil heterogeneity was taken into account. A column method was developed to measure the rate of pesticide transformation in the aquifer as input for models. The fluctuation of the concentration in the pumping well due to the application pattern was computed to be largest for aquifers with short characteristic travel times of the solute.
