Radon in Water Check
Measures radon gas dissolved in your well water - which can also raise indoor-air radon.

The Radon in Water Check measures radon - a naturally occurring radioactive gas - dissolved in your well water. Radon forms as uranium in bedrock breaks down, and groundwater from granite and similar rock can carry it straight into your home. It matters two ways: you ingest it by drinking the water, and it escapes into the air during showering, laundry, and dishwashing, adding to your home's indoor-air radon. Radon is invisible and odorless, and water testing requires special collection to keep the gas from escaping the sample. This kit measures the radon level in your water so you can decide whether mitigation is warranted.
What it tests for
- Radon gas dissolved in water (reported in pCi/L)
- An input to your home's overall radon exposure
- A baseline for deciding on aeration treatment
Why it matters
Radon is a leading cause of lung cancer, and water is an under-recognized source: every shower or wash releases dissolved radon into the air you breathe. Because air-radon testing alone misses the waterborne contribution, a dedicated water-radon test gives the full picture - and if levels are high, an aeration system at the wellhead can remove it effectively.
Who it is for: Best for wells in granite or radon-prone regions, homes that have already measured elevated indoor-air radon, and anyone doing a thorough new-well or home-purchase workup. Often paired with the uranium test since both come from the same bedrock.

Frequently asked questions
- How is radon in water different from radon in air?
- Radon-in-air testing measures the gas in your home's air; this test measures radon dissolved in your water. Water radon escapes into the air during showering and washing, so it adds to your indoor-air levels - which air testing alone can miss.
- Does radon water testing need special handling?
- Yes. Radon escapes from water easily, so the kit uses a specific collection method to capture the sample without losing the gas. Follow the instructions carefully for an accurate result.
- What can I do about high radon in water?
- An aeration system installed at the wellhead is the most effective treatment - it strips radon from the water before it enters the home. Granular activated carbon is sometimes used for lower levels.
