Utah's private well pageUranium in Utah well water, by county
Uranium is worth checking in 7 of the 19 Utah counties with 10 or more tested wells, and rare in the rest. A county's share tells you how likely a problem is nearby. Only a test of your own well tells you what's in it.
How Utah compares with the rest of the country
Across Utah, about 1 in 39 tested wells had uranium over the EPA limit of 30 µg/L (17 of 665). Across all tested wells in the US it's about 1 in 22. That's less often than in the country as a whole. Counties still differ, so check yours below.
Why it matters: Drinking it for years can harm your kidneys and raises the risk of cancer.
Uranium comes out of the rock and sediment the wells draw from.
Uranium in tested wells, county by county
Share of each county's tested wells with at least one result over the EPA limit of 30 µg/L. Counties need 10 or more tested wells to be listed. Widespread means 15% or more, worth checking 5 to 15%, rare under 5%.

Where these numbers come from
- Lab tests: Water Quality Portal (USGS and EPA), well samples since 2000. A well counts as over if any of its tests was over the EPA limit of 30 µg/L. Wells tested for studies and monitoring, not a random sample of homes.
- Likely overstated: our own check of who tested the wells, when and where. How we check.
- State programs and links: Department of Health and Human Services (Utah Public Health Laboratory) and local health departments.
