Short description: | Before the Second World War, a roofing felt factory was located in the area of the study site and the neighbouring property to the east, which burnt down completely in 1938.In the area of the Hastedter Osterdeich property, a total of two areas of damage were localised, which can be differentiated into a central and a southern input area.In addition to considerable PAH contamination, high concentrations of CHC and BTEX were detected in the soil and groundwater. In the course of several investigation steps, the source areas were roughly localised and delimited, including detailed investigation of the contaminant plume in the groundwater downstream. |
