Abstract The integral pumping test method (IPT) can be used to investigate the spatial heterogeneous and temporal variable release of wastewater constituents from urban line sources (e.g. leaky sewers). Long-time pumping (several days) and simultaneous sampling yield concentration-time series that can be used for the evaluation of average concentration Cav along control planes in an aquifer. The applied sampling schedules during IPT operations have an important influence on the accuracy of the Cav estimations. A detailed investigation of 30 high-frequency concentration-time series from two field sites in the city of Leipzig (Germany) was performed to optimize the number of samples and the sampling time of IPTs in the vicinity of urban line sources. The results show that IPTs with a low number of samples can also provide reliable Cav values. Concerning the optimal sampling times a sampling scheme with constant time intervals is preferable.
