Get your water tested in Nevada.

The labs Nevada 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

Nevada’s list has 52 labs certified to test drinking water: 14 in Nevada and 38 in other states. It also names 5 water utilities’ in-house labs, left out here because they test only their own systems’ water. The list says 13 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

Source: NDEP Laboratory Approval Status, drinking water parameters, 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.
