Abstract The former industrial region Bitterfeld/Wolfen has been widely affected by impacts of openpit lignite mining and chemical complexes for more than one century. The extensive chemical industry at the production location in combination with a deficient handling and dumping of chemical residuals cause a present groundwater contamination at a regional scale. The hydrochemical situation is characterized by a complex mixture of organic compounds with highly diffuse distributions. Additionally, the spatial timeshifting lignite mining highly affected the pollutant discharge from contaminant sources and strengthened the formation of complex contamination patterns. Based on a regional long term model for the simulation of groundwater flow and transport it is aspired to reconstruct preferential discharge pathways of selected substances, to prove known contamination sources and to identify potential further pollutant inputs. The usage of a backward particle tracking method indicates a clear advantage toward the prevailing forward transport modeling concept. This method was chosen by rare historical information about potential input sources like mining dumps in addition to their chemical inventory, in combination with extremely long computational times for a regional scaled transport simulation.
