I get that, yes. The other point is, how large a presence of lead in the water system is required to lead to adverse consequences or exceedances, to use the term you've used? They were using lead in the solder for copper piping up until the 1980s when they stopped doing that. You and I are almost old enough to remember leaded gasoline in cars, and there were excessive lead levels because of that. There were many different sources in the past where lead could be present.
If we turn this on its head, we can start looking at what we can do about it. You've talked about the City of Hamilton's initiative to provide loans to people to replace, at the very least, the service to the house. If we're inside a house, though, and there's lead piping there or even an excess of lead solder, that's a whole other issue. If you were sitting in our shoes making recommendations, would you want to see the presence of a lead service pipe or lead piping disclosed on a real estate listing so that people would know they are buying a house with this potential problem? Or would you ask, for instance, the home inspection business to test the water in the house and report the result to the would-be buyer?
