I'm not saying that you should be the ones to do it, except that we're dealing with private property. Someone has to tell the company responsible for the spill that it must also clean up the site.
In the case of air transport, the sky is the route, whereas for rail transport, we have tracks, railway yards and so forth. People like yourself must demand that cleanup operations be carried out. Sites are contaminated and companies are shirking their responsibilities. Someone needs to tell them to carry out cleanup operations.
