Get your water tested in West Virginia.

The labs West Virginia certifies to test drinking water, from the state’s own list of Aug. 20, 2026. A lab test is the only way to know what is in your own tap or well.

The short answer

West Virginia’s list has 50 labs certified to test drinking water: 23 in West Virginia and 27 in other states. 13 of the labs here are named for a water utility and may test only its own water, so they come last.

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.
