On the grounds of the state teaching and research facility in Oberschleißheim, the soil is contaminated with polycyclic aromatic hydrocarbons (PAH); Soil samples before a possible extension showed that some time ago. And what about the new “One Health Technology Campus” industrial park planned next door? The Greens in the local council are calling for an investigation there. It should be clarified beyond any doubt which pollutants may have to be disposed of there and who bears the costs.
A PAH concentration in the topsoil was determined during the subsoil examinations on the teaching and experimental property. In response to a request from the Greens state parliament members Markus Büchler and Claudia Köhler, the Bavarian Ministry of the Environment reported that the soil was to be classified as “polluted” down to a depth of 70 centimeters. Any excavation would have to “be recycled properly and safely”. No contamination can be detected in deeper layers, which is why the authorities have ruled out any dangers to the groundwater.
The Greens municipal council group is now warning that there is “the suspicion that the commercial planning area could also be contaminated with harmful PAHs”. The “One Health” campus connects to the west of the teaching and experimental property and its contaminated expansion area. In the investigation report, the Ministry of the Environment only stated that “speculations about the nature of adjacent areas” would not be made.
For the Greens there is a risk that the investor with whom the municipality wants to realize “One Health” will jump out of the way in the event of subsequent renovation costs. And this could “possibly have the consequence that the community is left with planning costs paid in advance,” warn the Greens. One should “never accept a pig in a poke,” warns councilor Ingrid Lindbüchl. “It would be completely unnecessary for the community to take a considerable economic risk without sampling,” emphasizes its parliamentary group spokesman Fritz-Gerrit Kropp and appeals to colleagues: “Please do not fly blind, like when opening up this industrial area to traffic.” Here the Greens complain that there are still no reliable road construction plans for the planned development via a western bypass.
According to the State Office for Health and Food Safety, the polycyclic aromatic hydrocarbons show “low acute toxicity”, i.e. toxicity, but some representatives of this group of substances show “carcinogenic properties”.
