Lead—source matters

Lead in tap water comes from household plumbing, not the source water or treatment plant. Decatur 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.

PFAS—25 compounds tested, none detected

EPA UCMR5 monitoring found no PFAS above the minimum reporting level in Decatur's water supply. This is a meaningful result: PFAS have been detected in roughly half of all tested US public water systems.
