A couple of those sites indicated that. When I look at those studies, that was not generally indicated. Am I correct? I looked at the studies. There are a couple of sites where the levels were high. Most of the sites were actually below the thresholds that had been set by the government.
I have another question, then, I guess. Have you changed the threshold? Are you changing thresholds? We have a completely different level of threshold depending on where we are. Canada has one. The U.S. EPA has a different one. The EU has another one. The EU is getting consistently tighter on their thresholds. What's going on with the thresholds? Are you changing them in Canada?
