Brief description:

Before the Second World War, a roofing felt factory was located in the area of the investigation site and the neighbouring property to the east, which burnt down completely in 1938. two areas of damage were localised in the area of the Hastedter Osterdeich property, which can be divided into a central and a southern entry area.In addition to considerable PAH contamination, high concentrations of MKW and BTEX were detected in the soil and groundwater, and the source areas were roughly localised and narrowed down as part of several investigation steps, including detailed investigation of the contaminant plume in the groundwater downstream.
