abstract = {Simulation models that describe the flow and transport
processes of pesticides in soil and groundwater are
important tools to analyze how surface pesticide
applications influence groundwater quality. The aim of this
study is to investigate whether the slow decline and the
stable spatial pattern of atrazine concentrations after its
ban, which were observed in a long-term monitoring study of
pesticide concentrations in the Zwischenscholle aquifer
(Germany), could be explained by such model simulations.
Model simulations were carried out using MODFLOW model
coupled with the HYDRUS-1D package and MT3DMS. The results
indicate that the spatial variability in the atrazine
application rate and the volume of water entering and
leaving the aquifer through lateral boundaries produced
variations in the spatial distribution of atrazine in the
aquifer. The simulated and observed water table levels and
the average annual atrazine concentrations were found to be
comparable. The long-term analysis of the simulated impact
of atrazine applications in the study area shows that
atrazine persisted in groundwater even 20 years after its
ban at an average atrazine concentration of 0.035 µg/L.
These results corroborate the findings of the previous
monitoring studies.},
