All this speculation is pointless. Superfund sites haven't had their cleanup funded by the companies doing the pollution since 1995, when congress decided that the tax on companies to fund such cleanup (which had funded 70% of the cleanup of superfund sites up to that point) no longer needed to exist, and since then the taxpaying public of you and me have been paying every single dollar for cleaning up the pollutants these companies emit.

You didn't have to pay to cleanup a site before using it, because the expectation was that you paid while running your business and the site would be cleaned before you wanted to utilize it.

But now the "Superfund" has been underfunded for like 20 years. Biden's IRA set up a new tax for ten years but, not sure how well that's going.

We literally had the system set up well and working fine, but it cost companies a few dollars so it had to go when the "Greed is good" folks came along.
