Lead—source matters
Lead in tap water comes from household plumbing, not the source water or treatment plant. Miami water leaves the treatment plant lead-free. Risk depends on your building's internal plumbing—highest in homes built before 1986, when lead solder was common. A NSF/ANSI 53 certified pitcher or under-sink filter removes lead at point of use.
