Our paper looks at an area near the town of Międzychód that is heavily contaminated by petroleum substances. Due to a pipeline failure in 1996, 70 tons of petrol were dumped into groundwater and soil. Initially, contamination occurred solely near storage base No. 71, and over the next few years it expanded beyond the area of the base. At present, more than 3,000 m2 of land is considered to be contaminated. In spite of the reclamation efforts, the analyses of water and soil samples continue to indicate their heavy contamination and presence of above-average petrol and oil concentration. Furthermore, the hydrogeological conditions of Międzychód are favorable for the contaminants to migrate from the surface into the groundwater. Therefore, subsequent and extensive reclamation works are still to be strongly recommended.
