Any signs of change?

Yes. Although the sources of the PFOA in the environment are not clearly understood, it is increasingly apparent that other fluorinated chemicals may play a significant role. The objective of the EPA's work is to identify all sources, then reduce or eliminate them. In 2000, because of PFOS (a related chemical), 3M stopped making ScotchGard®. A professor at the University of Toronto has been measuring the levels of these chemicals found in arctic wildlife for years, and he recently reported that the levels found in arctic seals have been dropping ever since.
