2: A Touchy Subject

The carpet executive asked not to be identified for this story. Researcher Aaron Fisk says PFOA is a very touchy subject. Fisk says he got a cold reception from the industry when he approached them about the study.

"Once we got the results, I started to feel there was knowledge about the problem and a history and issues related to the land application system…I know there's people concerned about that and thinking about that."

Fisk praises the land application system. He says it helps lower the amount of PFOA entering the river.
