Get your water tested in Idaho.

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

The short answer

Idaho’s list has 33 labs certified to test drinking water: 10 in Idaho and 23 in other states. 2 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.

What to ask a lab to test

Source: Idaho Bureau of Laboratories, drinking water laboratory certificates, 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.

A lab named for a water utility is listed apart. Distances on town pages are straight lines between ZIP code centers from the Census 2020 gazetteer. How labs are listed here.
