Thanks for the info. I watched "Rescuing the River: The Raritan" in early July. It was very interesting, though I felt it focused a lot on companies involved in pollution/dumping over the years, and efforts like Superfund legislation to get companies to take responsibility and help clean up sites. Not as much focus on the river as I would have liked. That said, it was well worth watching and I have it DVR'ed.
