      abstract     = {In Germany, about 1,000 groundwater bodies were delineated,
                      of which almost $40\%$ do not reach the quality target set
                      by the EC Water Framework Directive (WFD) for the good
                      chemical status", primarily because of their high nitrate
                      concentrations. Accordingly, programmes of measures were
                      initiated to reduce the nitrate pollution of groundwater by
                      minimising the excessive application of nitrogen in
                      agricultural practices. A three-tier conceptual
                      hydro(geo)logical model was developed to evaluate the
                      efficiency of such measures on the basis of data available
                      in the German Federal States. The first tier consists of
                      analyses of interrelations between land use, nitrate
                      concentrations measured in groundwater and in the
                      hydrogeological system; moreover, potential hotspots are
                      identified. The second tier is an assessment of the
                      reduction of N excesses in agriculture that is necessary to
                      reach the quality target for groundwater of 50 mg/l NO3. The
                      third tier evaluates the time elapsed between the
                      introduction of a nitrogen-reducing measure and its impact
                      on the nitrate concentrations at the groundwater-monitoring
                      stations. The methodology was successfully tested in a
                      groundwater body situated in the North German Lowland that
                      is displaying typical nitrate-pollution patterns.},
