Anomalously high nitrate concentrations are found in aquifers with agricultural lands in their recharge area, with restricted water outflows and with partially penetrating wells which induce ground water recirculation. A comprehensive methodology is proposed, which characterizes the source term--nitrate leaching--in time and space and couples it to the hydrodynamic characterization of the aquifer. The methodology is applied to a heavily polluted aquifer. Results show that poor management of irrigation and fertilization practices cannot be separated from unfavorable hydrodynamic conditions to explain concentrations as high as 160 mg/L NO{sub 3}{sup {minus}}-N in ground water.
