Your county health department
Utah doesn't run a statewide free testing program that we know of. Some county health departments test wells or sell kits, so call yours first.
Utah's private well pageManganese is widespread, over the limit in 15% or more of tested wells, in 5 of the 23 Utah counties with 10 or more tested wells. 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.
Across Utah, about 1 in 9 tested wells had manganese over the EPA health advisory of 0.3 mg/L (153 of 1,381). Across all tested wells in the US it's about 1 in 7. Utah is about average, so the county you live in tells you more than the state does.
Why it matters: High levels over many years may affect the nervous system, and babies are more sensitive to it. It also leaves black stains.
Manganese dissolves out of rock and soil, especially in water with little oxygen.
Share of each county's tested wells with at least one result over the EPA health advisory of 0.3 mg/L. Counties need 10 or more tested wells to be listed. Widespread means 15% or more, worth checking 5 to 15%, rare under 5%.

* Likely overstated. These shares come from a narrow set of wells, so they probably run high for the county as a whole:
5 more Utah counties have 1 to 9 tested wells for manganese, too few to rate.
