Radon in water
Can radon get into well water?
Radon dissolved in groundwater is released into indoor air every time you shower or run a tap. Shield bedrock wells are the risk case.
How you notice it
- No water symptoms — found by testing water and indoor air
- Elevated indoor radon already measured
- Drilled well in granite or Precambrian shield
Why it happens
Uranium decay in crystalline bedrock produces radon gas, which dissolves readily into groundwater held in fractures.
The fix
- Test radon-in-water alongside indoor air
- Bubble aeration at the point of entry is the accepted fix
- Granular activated carbon only for low concentrations
