I traced the area with JOSM. How should I tag it?

Check out the protected area tagging, there’s a contamination attribute that I think should fit this scenario.

Thanks. I followed your advice. Now it renders on IHM (but not on the OSM site).

Well, OSM has their rules set and we have ours, shouldn’t affect the mapping though.

zstadler added the barriers. I added everything to a relation: https://www.openstreetmap.org/relation/7382436
