Pollution contamination at AB Elementhus Mockfjärd, established in 1976

Dear forum members,

I have a question regarding my parents' house, which was built in 1976 in Baden-Württemberg, near Rottenburg am Neckar. My father should still have all the documentation. I would like to know if anyone can help me regarding the potential pollutant contamination. I have read the forum posts and already received some helpful information. (schwedische FH eher nicht belastet, beproben lassen, etc.). I also wanted to ask if anyone might have a pollutant analysis or similar, specifically about the Mockfjärd house type, which I could possibly use as a reference for my own investigation. I would also be willing to pay something for it. Currently, I only have a detail of the exterior wall; a photo of the house itself I can still get and upload.

Best regards

That seems to be spam. Does it lead to an Otto merchandise homepage?

Dear forum members,
here is another view of the house, unfortunately from a bit of a distance.
