How To Get Rid Of Radon In Water

So, you tested your water and found radon. Yikes, right?

It sounds like something out of a sci-fi movie. But it’s actually a real gas that can sneak into your home through well water.

Don’t panic. We’re going to fix this together, one chatty step at a time.

First, Let’s Get One Thing Straight

Radon in water isn’t the same as radon in air. They’re related, but different problems.

The scary part? Most radon-related lung cancer risk comes from airborne radon. But water can release that gas into your air every time you shower, wash dishes, or flush the toilet. Yes, flush.

So you’re basically giving your lungs a little gas bath with every splash. Not great.

Step One: Know Your Enemy (And Your Test Results)

You need a proper test. Don’t just guess based on neighborhood rumors.

If your water radon level is above 10,000 picocuries per liter (pCi/L), you’ve got a problem. That’s the EPA’s warning zone.

Below that? You might be okay, but check with your local health department. They love this stuff.

Your Two Main Weapons

You have two solid options to kick radon out of your water. Neither involves a magic wand, sadly.

But they’re both surprisingly effective. Let’s break them down.

Option 1: Aeration (The Fancy Fountain)

This is the gold standard. It’s like giving your water a spa day.

An aeration system sprays your water into a tank, letting the radon gas bubble out into the air. Then it vents that gas safely outside.

It sounds complicated, but it’s basically a high-tech fish tank bubbler. Only it’s for your drinking water.

Option 2: Granular Activated Carbon (GAC – The Sponge)

This is the cheaper, simpler cousin. Think of it as a super-powered Brita filter.

Water passes through a big tank of carbon. The radon sticks to the carbon like gum to a shoe.

It’s effective, but there’s a catch: the carbon becomes radioactive over time. You’ll need to dispose of it as low-level radioactive waste. Yes, really.

Don’t just toss it in the trash. That’s a no-no.

Which One Should You Pick?

Good question. Let’s play a quick game of “Pros and Cons.”

Aeration is better for high radon levels. It removes 99% of the gas. The downside? It costs more and needs more space.

GAC is cheaper and easier to install. But it only removes about 90-95% and requires careful disposal. Plus, you have to change the filters often.

If you have radon levels over 20,000 pCi/L, go with aeration. Your future lungs will thank you.

A Word On Whole-House vs. Point-of-Use

Do you treat just the kitchen tap, or the whole house? Whole-house, every time.

Why? Because you breathe radon from every water source. Your shower is a major culprit.

Treating just the kitchen sink is like putting a bandaid on a bullet wound. Fix the whole system, friend.

What About the Air Radon?

Don’t forget: if you have radon in water, you probably have it in your air too. Test your air separately.

If your air radon is high, you’ll need a sub-slab depressurization system. That’s a fancy vacuum for your basement floor.

It’s a whole other article, but know this: water and air radon are a team. Deal with both.

Where Do You Even Find These Systems?

Call a licensed radon mitigation contractor. These are not DIY projects for a weekend.

Actually, you could try a DIY aeration system if you’re super handy. But one wrong pipe and you vent radon into your kid’s bedroom. Not ideal.

Just pay a pro. It’s worth the peace of mind.

The Gross But Important Final Note

Once you install a system, test your water again. Make sure the radon is actually gone.

Also, replace filters and check the vent pipes yearly. Radon doesn’t take vacations.

And if your carbon tank gets heavy? That means it’s full of trapped, radioactive gas. Handle it with care.

You’ve got this. Seriously.

Radon is scary, but it’s also fixable. You’re already ahead by reading this instead of ignoring it.

Now go book that test. And maybe take shorter showers until then. Your lungs will high-five you later.
