Radon from Well Water: Impact on Indoor Air Quality

When considering indoor air quality, we often focus on common issues like dust, pollen, mould, or chemical fumes. However, radon is another serious and often overlooked threat that can impact the air inside our homes. More specifically, radon enters a home through well water.

At Peerless Air, we understand that protecting your indoor air quality means looking beyond the obvious. Radon is an invisible, odourless, naturally occurring gas that poses a real health risk. 

While most people know that radon can seep into a home through the soil beneath the foundation, many aren't aware that private well water can also be a significant source of radon.

We provide not only air purification solutions but also the education that empowers homeowners to take proactive steps. So, let's take a closer look at how radon from well water affects your indoor air and what you can do about it.

What Is Radon and How Does It Get Into Toronto Water?

Radon is a radioactive gas that forms naturally when uranium in soil, rock, or water breaks down. It can be found in almost every part of the country, and homes with private wells may be especially at risk.

When groundwater flows through bedrock that contains uranium, radon can dissolve into the water supply. The gas is released into the air if that water is used for activities like showering, cooking, or laundry. 

In other words, whenever you run your tap or step into a hot shower, radon in the water can be transferred into the air you breathe. This issue is common in homes that rely on private wells rather than municipal water systems. 

Unlike public systems, private wells are not subject to regular testing and regulation for radon, so many homeowners are unaware of the levels they're exposed to. Dr

Why Radon Is a Serious Health Risk In Toronto

Radon exposure is the second leading cause of lung cancer after smoking, according to health authorities like the U.S. Environmental Protection Agency (EPA) and Health Canada. The danger comes from inhaling radon gas over long periods, especially in enclosed indoor environments.

When radon is released from well water into the air, it can accumulate in poorly ventilated spaces, especially basements and bathrooms. Continuous exposure to elevated levels increases the risk of developing lung cancer over time, even for people who have never smoked.

We believe every homeowner has a right to clean air, starting with knowing what they're breathing. Understanding the source of radon is a key part of managing risk.

Testing for Radon in Water and Air

The first step is identifying the problem. We always recommend starting with a radon air test, especially if your home has a basement, is in a high-radon region, or relies on well water.

If elevated levels are detected in the air, a water test can help determine whether the source is your water supply. Radon in water is typically measured in picocuries per litre (pCi/L), and even relatively low levels can contribute significantly to indoor air concentration.

At Peerless Air, we work with certified professionals who can assist with testing both the air and water in your home. Once we understand the source and extent of the radon, we can help you plan a course of action that protects your family's health.

Mitigation Solutions That Work

A sub-slab depressurization system is usually the go-to solution if radon comes from the soil beneath your home. However, if the source is well water, the approach is different.

We typically recommend a point-of-entry treatment system, such as an aeration system, to remove radon from water. This method agitates the water and vents the released gas outside before the water is distributed throughout your home. 

There are also granular activated carbon (GAC) systems, which can be effective in some cases, although they require regular maintenance and are not ideal for high concentrations.

Alongside water treatment, we often look at improving indoor air quality through whole-home ventilation and air filtration systems to manage radon and other contaminants. Our goal is always comprehensive, long-term solutions tailored to your specific needs.

Taking Proactive Steps for a Healthier Home

Radon exposure is preventable, but it takes awareness and action. If your home uses well water, we strongly encourage you to have it tested. Many homeowners we've worked with are shocked to discover elevated radon levels and grateful to know there are effective ways to address them.

At Peerless Air, we're committed to creating healthier indoor environments. From radon mitigation to advanced air filtration, we take a whole-home approach, prioritizing safety, comfort, and peace of mind.
