Certified labs by state
Nevada
Nevada’s official private-well guidance says private well water quality is not regulated by the state, so well owners are responsible for testing their own drinking water. For Nevada residents, the key current sources are NDEP’s Bureau of Safe Drinking Water pages for certified labs and private wells, plus University of Nevada, Reno Extension publications for testing schedules and radon information.

What to do next
- Use NDEP’s certified drinking-water lab page first, and confirm the lab is certified for the specific analytes you need.
- If your well water changes in taste, odor, color, or after flooding, maintenance, or illness in the household, test promptly rather than waiting for the annual check.
- If radon is a concern in your area, use UNR Extension’s Nevada Radon Education Program to locate a test kit or borrow a radon monitor.
