But they haven't cleaned them up?

  With a lot of these substances, cleaning them up doesn't just cost a lot of money, it also takes a lot of time.

  Once they're totally cleaned up they're no longer superfund sites. This is like looking at my list of _open_ bug tickets and complaining that not a single one of them is done. That said, it can be hard to get a lot of these sites all the way to 100% cleaned up, and there's a lot of non-engineering obstacles. There's landowners and neighbors with all kinds of differing incentives, as in a Queens, NY site where they want to dig up and get rid of some radiation but there are businesses who have already been built atop it and would have to be destroyed.
