Numerical modelling as a tool for optimisation of ground water exploitation in urban and industrial areas

It was proved that long-term pumping intensity (140 l/s) does not guarantee protection of the water quality. A reduction in the pumped discharge to 120 l/s was recommended. To ensure the long-term water quality in the water withdrawal area without any restriction on pumping discharge, a reduction in ammonium in the vadose zone by the 50 % would be required. However, so far, no remediation activities have been started.
