Contaminants in Florida water

89 measured  ·  135 readings over a legal limit

Every substance measured across Florida’s community water systems, with the number of systems that reported it and how many were above the federal legal limit. A substance appearing here means it was measured, not that it is unsafe.

67 contaminants have their own page: those measured in 5 or more systems, plus any that exceeded a legal limit anywhere in Florida. The rest are listed here with their totals, because too few systems reported them to say anything useful on a page of their own.
