Radon Water Treatment in Londonderry, NH

New Hampshire’s granite bedrock gives off radon, and some of it dissolves into well water. Once that water runs through a shower, dishwasher, or washing machine, the gas escapes into the air you breathe, and the state estimates that every 10,000 pCi/L of radon in water adds about 1 pCi/L to the air indoors.

At Mainline Plumbing, we test water for radon, whether it comes from a private well or a town supply, and install or repair the equipment that reduces it before it reaches your taps. We match the treatment to your results, since radon levels can vary a great deal from one source to the next.

Our Radon Water Treatment Services in Southern New Hampshire

The right setup depends on how much radon is in your water and how much is in your air, so we start by measuring both.

Radon Water Testing

A water test gives the level in pCi/L, while an air test shows what you’re breathing. Having both lets us decide whether treatment makes sense, and we can start with well water testing to get the numbers.

Radon Removal Systems

If your results call for treatment, we install a radon removal system sized to your water and your household’s water use. We explain what the numbers mean and what to expect before we start. Our whole-house water filtration systems can cover anything else your water needs.

Radon System Maintenance and Repair

Radon equipment can lose effectiveness without any obvious sign, so it needs regular upkeep. We maintain and repair existing systems, and we’ll tell you honestly if an older unit needs more than a fix.

When to Consider Radon Treatment

Knowing when to treat radon in your well water can help you protect your home’s air quality and your family’s health. Here are a few situations when testing or treatment makes sense:

  • Radon in water is 10,000 pCi/L or higher: The state recommends treating the water. If levels fall between 2,000 and 10,000 pCi/L and indoor air radon is 4 pCi/L or higher, treatment may also be a good idea.
  • You haven’t tested your well water for radon: Testing is a good first step, since radon can be present in well water without any obvious signs.
  • Your existing radon system isn’t working properly: Repairing or replacing older equipment can help restore its effectiveness.
  • You’re buying a home with a private well: Test both the water and indoor air for radon before closing so you know what you’re dealing with.

The NH Department of Health and Human Services explains these guidelines in its radon mitigation guidance, and radon in your air is usually the bigger concern. We can help you sort out which results matter for your home.

What to Expect During Radon Water Treatment

We keep this straightforward and explain what the numbers mean.

  1. Test the water and air: We sample your water and may recommend an air test if you haven’t had one recently.
  2. Compare to state guidance: We read your results against New Hampshire’s recommendations for radon in water.
  3. Choose and install: We recommend aeration or carbon based on your levels and set it up.
  4. Retest and maintain: We confirm the radon dropped and set a schedule for upkeep.

Radon in well water can change from test to test, so we’ll suggest when to check it again.

Frequently Asked Questions

Is it safe to drink water with radon in it?

The biggest health concern with radon is breathing it in, though drinking radon-containing water carries some risk too. Radon in well water can escape into your air when you shower or run appliances, which is why the state recommends treatment at higher levels.

How much does a radon water mitigation system cost?

Cost depends on your radon level, how much water your household uses, and the equipment your home needs. We test first and explain your options before you decide.

How do you remove radon from well water?

The two common methods are aeration, which lets radon escape from the water and vents it outside, and granular activated carbon, which holds radon as water passes through. Aeration generally suits higher levels, and carbon suits lower ones.
