You may be right, but the fact that residents in that town are saying that it hurts to breathe and people are feeling sick and they maintain the stance that the air and water "is fine" it makes me a little doubtful. Not to mention the smoke from the burn carried into PA because there was wind during the burn. And a few day ago wind apparently picked up PM(particulate matter) from the area and carried that into PA. This is something we have to be mindful of. Chemical spills and burns don't go away just like that. People have the right to question when it looks like they are being lied to.
