The city of Ribnitz-Damgarten has acquired the former Pütnitz airfield from the Federal Institute for Real Estate and intends to develop the area for tourist use. Due to the historical use of the site, both the soil and the groundwater are contaminated with mineral oil hydrocarbons, PAHs and BTEX, among others. Based on previous research campaigns, a total of 41 problem areas were identified. Furthermore, there are extensive sealed surfaces on the former airfield site as well as buildings that were erected as part of the military use of the site. In the course of the soil, groundwater and building substance investigation put out to tender here, the 41 problem areas are to be examined in more detail on the one hand and a preliminary waste law characterization is to be carried out on the other hand for the sealed surfaces and buildings.

In addition to the previous investigations, further soil and groundwater investigations will be carried out. For soil investigations, small pile boreholes (KRB) with a diameter of 80 mm must be drilled to depths of 3 – 5 m. Due to the high number of planned wells, it is imperative that at least 2 drilling crews be used simultaneously. In addition, the drilling points will be measured according to height and location. For the collection of groundwater samples, pile driving gauges are to be used in some of the previously performed KRB. In addition, direct push soundings are to be carried out.
