Get your water tested in Tennessee.
The labs Tennessee certifies to test drinking water, from the state’s own list of Oct. 2, 2026. A lab test is the only way to know what is in your own tap or well.
The short answer
Tennessee’s list has 37 labs certified to test drinking water: 13 in Tennessee and 24 in other states.
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.

What to ask a lab to test
- On a private well: no one else tests it. What to test a well for, and how often.
- On city water: your utility tests what leaves the plant, not what your own pipes add. Testing your tap for lead.
- What it costs: fees vary by lab and by test, and some states test wells for free. What a water test costs.
- Anything your utility’s report flags: a lab certified for that contaminant can test your own tap. Tennessee utilities’ reports.
