Downstream
Oldie but goodie four-part video about the Merrimack River Watershed. Please note that the video is about 20 years old and seems to imply that the water quality of the Merrimack River is now clean. While the river IS cleaner than it was 50 years ago when the river would catch on fire (yup, that happened), it still has a long, long way to go.
