I haven't paid attention to a Superfund case in a long time, so it's interesting to see that the EPA actively looks for the companies responsible for the pollution. Their findings are damning but unsurprising.

Environmental Protection Agency officials who made the canal a Superfund site last week have already named nine responsible parties and are now eying 20 other companies, including Chevron, Exxon Mobil, Kraft and Citigroup.

"This is a historical puzzle we're putting together here," said EPA regional administrator Judith Enck. "This site has a very long legacy of toxic pollution."

The hunt started at the Kings County records office in downtown Brooklyn, where investigators are poring over 150 years of property documents.

The article goes on to point out that while these companies may not have directly polluted Gowanus, they own or acquired companies that did.
