If you look at our water supply in Vancouver, you see a phenomenal water supply, and corrosion control is used effectively. Even though, for example, my home in Fairview had old lead pipe—we replaced it, but there is lead pipe there—as long as the corrosion control is done well, we shouldn't have a problem unless there's maintenance or other things that disrupt it.
I would also say that other communities in B.C., such as Pemberton, don't have adequate corrosion control. Not only do they have problems with their pipes and their plumbing because of that, but they also have problems with lead. They don't have the facilities to bring about their corrosion control, so I think one big part of this discussion needs to take into account the smaller municipalities, the townships, and the first nation communities that don't have the facilities for corrosion control.
