Uranium in Indiana well water, by county

Uranium is rare in tested Indiana wells: in all 5 counties with enough tests, fewer than 5% of tested wells were over the limit. 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 Indiana compares with the rest of the country

Across Indiana, none tested wells had uranium over the EPA limit of 30 µg/L (0 of 145). Across all tested wells in the US it's about 1 in 22. No tested Indiana well was over, but your own well can still differ, so test it if you're unsure.

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.

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: Indiana Department of Health.
