Get your water tested in Vermont.
The labs Vermont certifies to test drinking water, from the state’s own list of Sept. 28, 2026. A lab test is the only way to know what is in your own tap or well.
The short answer
Vermont’s list has 46 labs certified to test drinking water: 6 in Vermont and 40 in other states. One of the labs here is named for a water utility and may test only its own water, so it comes last. The list says 26 take samples from homeowners.
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. Vermont utilities’ reports.
Source: Vermont Department of Health, laboratories certified for drinking water analysis, dated Sept. 28, 2026, read Oct. 16, 2026. Labs are listed as the state lists them; what each is certified for is as far as the list says. Certifications change, so a lab’s own word is the latest.
