If I may, I'll answer that for her. The mercury levels in our area are from historical discharges, mainly from a Domtar pulp and paper mill that has since closed.
What we're seeing is that the mercury levels immediately adjacent to our community are dropping over time, but it also seems that the sediment is resuspending and moving further downriver into the Quebec portion towards Montreal. We don't know how much of it is redepositing further downstream versus, in our area, being covered up by other, cleaner sediments. In our remarks, we said that one of the things that would be helpful is to do a follow-up study of contaminant levels in fish, sediments, and plants.
