No, they won't, at least not in any concentration greater than what arrives to the tank naturally via dust and the resident population that is in all of our tanks. If your water starts smelling terrible or you get a boil notice, then you've got it in the system. The stuff is somewhat toxic to people, so they don't mess around when it gets into a municipal water supply.
