The Bernau place (Germany) is heavily polluted by trichloretilene (TCE). In 2001, to remediate the place, a cleaning plant (CP) has been started. It occupies the original TCE spill area. Initially, it was believed that the nearby located TCE - contaminated pool was the natural sink for the original spill body. A hidrogeological model (HM) was built to simulate spatial migration of this dense pollutant. In 2005, it was found out that TCE from the spill area cannot reach the pool. The second, unknown before, TCE spill was detected in the vicinity of the pool. Therefore, the hydrogeological and contamination processes proved to be quite different from the ones assumed initially. It was necessary to reconsider the place remediation plans and to implement the new knowledge in HM. The case shows that incomplete initial data of the place hydrogeology and contamination concentrations may lead to false interpretation of problems to be modelled. The hydrogeological model of the Bernau place area has been corrected. Although the corrected model rightly performs main events of the TCE migration, the model is still rather far from perfection, because some principal unknown impacts may not be accounted for.
