You don’t think the sites are contaminated?
I never said that but I worked for an environmental reclamation company and seen how the game works. A half billion dollars is allocated for a site and a million is spent.
We once “cleaned up” a mercury contaminated site by grading the land, spraying a de-binding agent on the ground, planted grass seed, and put up a fence. It cost less than a million dollars of the $6 million allocated. The rest went to various environmental activism groups, local politicians, to the company that actually contaminated the land, and environmental training programs to create clowns like you who cry over the sight of an oil spot on the driveway.
