That's largely correct. Their work, of course, was criticized because it was at very few stations on the river. And it was dismissed in part because it was felt that the background for fish in mercury, for example, was always high, which is true. But there have been studies at the experimental lakes area that I reference in my brief that show that if you put more mercury in the river, the mercury in fish will go up. So what's happening with respect to mercury is not good news. What were originally high mercury levels are probably going higher. We have the fish to analyze, so we'll know within a year.
