For the 5th National Environmental Outlook 2000-2030 the breakthrough of nitrates is studied in groundwater abstraction wells located in Twente and the Achterhoek. In this report model choices and input data are described and discussed in detail. Model results indicate that at present nitrate concentrations are stable or slightly decreasing. The results also show that in 2030 the nitrate contents in the pumping stations located in the 'Achterhoek' will not exceed the EC drinking standard (50 mg L-1), while in 'Twente' several pumping stations will exceed the EC standard after 2030. Special attention is paid to denitrification. All calculations are performed twice: with and without denitrification. It appears that denitrification leads to co...
