Get your water tested in Florida.

Florida’s list has 212 labs certified to test drinking water: 141 in Florida and 71 in other states. It also names one water utility’s in-house lab, left out here because it tests only its own system’s water. 72 of the labs here are named for a water utility and may test only its own water, so they come last.

Florida’s labs here are those its Department of Health certifies for drinking water, as listed in TNI LAMS, the national registry it reports to. It doesn’t say which labs take outside samples, and some here are a county’s or a utility’s own, so call first.

Certification is test by test, so check that a lab is certified for what you want tested, and call first: it will say which bottles to use and how soon the sample has to arrive.
