You said it Barfo.... "in this article".
Ya see, I did a little light reading beyond the shit that Rasta links because usually his links are poor quality.
At any rate my friend, the site is a Government Superfund site.
"EPA may identify parties responsible for hazardous substances releases to the environment (polluters) and either compel them to clean up the sites, or it may undertake the cleanup on its own using the Superfund (a trust fund) and costs recovered from polluters by referring to the U.S. Department of Justice."
The site has been a superfund site since 1983, If I am reading their listing correctly, meaning they've had (the EPA) ~30+ years to get this shit taken care of, although it doesn't appear that they did anything until 1996.
