How A River That Used to "Run Red" With Pollution Got Clean

June is National Rivers Month, which means it’s a good time to talk about a recent film chronicling the effort to clean up the Nashua River. It’s called “Marion Stoddart: The Work of 1000” and has been screened at a number of environmental film festivals.

Susan Edwards is the film’s producer, and she talks with All Things Considered host Brady Carlson about, the film, Marion Stoddard and the Nashua River.
