Heh, some landowner near me owned a piece of contaminated property. Technically worthless but was getting some lease money for a shop on the property. I think their game plan was for the city to grow and it being valuable to excavate one day for a condo or other building. Soil remediation is a lot cheaper when you dig anyway.

Transit agency tried to expropriate for a train station at market value: ie $0.

Looks like it got settled out of court: https://canliiconnects.org/en/commentaries/88178
