Certified labs by state
Utah
In Utah, private wells are outside the Utah Division of Drinking Water’s public-system rules, so residents are directed to county/local health departments and the state’s private-well guidance pages. Utah also treats radon as a notable statewide issue—DEQ says 1 in 3 Utah homes has elevated radon—and DHHS tracks contaminants such as arsenic, nitrates, radium, and uranium in drinking-water data.

Key facts for Utah
- Utah Public Health Laboratory says private wells should be tested annually for nitrate, pH, total dissolved solids, and total coliform/E. coli. (Private Wells)
- DEQ says private wells are not regulated by the Division of Drinking Water; local health departments may have rules for private supplies. (Consumer Guide)
- DEQ says your local health department is the primary contact for private wells that are not part of a public water system. (Local Health Departments and District Engineers)
- Utah DHHS says naturally occurring drinking-water contaminants in Utah include arsenic, radon, and uranium. (Drinking Water Contamination)
- UPHL’s county table includes arsenic testing in Davis, Salt Lake, Tooele, TriCounty, and Weber-Morgan private-well recommendations. (Private Wells)
- DEQ’s radon program says 1 in 3 Utah homes has elevated radon; if indoor radon is high and you use a private well, test the water. (Radon Program/Frequently Asked Questions)
What to do next
- Start with your county local health department, because Utah directs private-well owners there for any county-specific required or recommended tests.
- Order at least the Utah-recommended annual panel first: nitrate, pH, total dissolved solids, and total coliform/E. coli.
- If you live in an area where county guidance adds metals or salts—such as arsenic, fluoride, sulfate, selenium, lead, or mercury—ask the lab for that broader county-specific panel too.
