I know this river as the largest river on the Pacific coast of the United States. Now, thanks to your message, I know that this is a river with a long history and unfortunately environmental problems. I'm always against human carelessness. It's sad to see how the monetary interests of a group of people become ahead of the environment. I first read about the Hanford Reservation, before that I did not know about its existence.
Thank you for an interesting and informative article!
