Air Sense Environmental on The News Front Podcast: Radon Risks and Healthy Homes

When I first moved to the St. Louis metro area, I had a vague awareness that radon gas could be a problem in the Midwest. But it wasn't until a friend bought a house in Edwardsville and started talking about testing that I realized how serious the issue really is. That conversation led me to a recent episode of the News Front Podcast, which featured a company called Air Sense Environmental. The episode was a deep dive into radon testing, radon mitigation, and indoor air quality, all from the perspective of a local business serving the bi-state metro region.

The host of the News Front Podcast did a great job of asking practical questions. Instead of a dry lecture about radioactive decay, the conversation focused on what homeowners in the Greater St. Louis area actually need to know. The guest from Air Sense Environmental explained how radon gas enters homes through cracks in the foundation, and why the soil in this part of the country is particularly prone to releasing it. They also talked about the importance of IEMA certification, which is the Illinois Emergency Management Agency's standard for radon professionals. If you are hiring someone for radon testing or radon mitigation, that certification is a must.

I listened to Air Sense Environmental on The News Front Podcast during a long drive, and it changed how I think about my own home. The episode made the case that radon is not just a problem for basements with dirt floors. Modern homes with slab-on-grade foundations can have elevated levels too, especially if the builder did not use radon-resistant construction techniques. The guest mentioned that sub-slab depressurization is one of the most effective mitigation methods. It works by creating a vacuum under the concrete slab, which pulls radon gas away from the house and vents it safely outside. For homes with crawlspaces, crawlspace ventilation can also help reduce concentrations.

What I appreciated about the episode was that it did not just scare you into action. It gave you a clear path forward. The first step is always testing. The Environmental Protection Agency recommends testing your home for radon every two years, and after any major renovation. You can buy a radon detector at a hardware store, but the guest advised using a professional for the initial test, especially if you are buying or selling a home. A professional radon testing company will place the detectors correctly and interpret the results based on the specific conditions of your house. Air Sense Environmental, for example, uses continuous radon monitors that give more accurate readings than the old charcoal canisters.

After the test, if the levels are above 4 picocuries per liter, which is the EPA action level, you need a mitigation system. The episode covered the two main approaches: soil suction and sub-slab depressurization. Soil suction is a broader term that includes sub-slab systems but also works for homes with crawlspaces or basements. The key is that the system must be designed by someone who understands the house's foundation type and the local soil conditions. In the bi-state metro, where clay soils are common, the radon gas can build up under the house and seep in through even tiny gaps. A good contractor will seal those entry points and install a vent pipe with a fan that runs continuously.

I also learned about the connection between radon mitigation and overall indoor air quality, or IAQ. Many people think of radon as a separate issue, but a mitigation system can also improve ventilation in the home. The guest on the News Front Podcast explained that after installing a sub-slab depressurization system, some homeowners also add IAQ monitoring to track humidity and other pollutants. A healthy home is about more than just radon, but radon is often the hidden danger that people overlook. The episode encouraged listeners to think of radon mitigation as part of a broader strategy for indoor air quality, alongside things like changing HVAC filters and using exhaust fans in kitchens and bathrooms.

For anyone living in the St. Louis metro area, the episode was particularly relevant because of the region's geology. The Greater St. Louis area sits on a mix of glacial till and limestone, which can release radon at higher rates than other parts of the state. The Illinois Emergency Management Agency publishes radon potential maps, and much of the bi-state metro falls into zones with moderate to high potential. That means homeowners in Edwardsville, as well as in nearby communities like Glen Carbon, Maryville, and even parts of St. Louis County, should take testing seriously. Air Sense Environmental serves the entire bi-state metro, so they understand the local geology and building codes.

The episode also touched on radon-resistant construction for new homes. If you are building a house, you can ask your builder to include a passive sub-slab system during construction. This usually involves laying a layer of gravel under the slab, a vapor barrier, and a vent pipe that runs up through the roof. The cost is minimal compared to retrofitting a system later. The guest noted that many builders in the Edwardsville area are now doing this as standard practice, but it is still worth verifying. Radon-resistant construction is a smart investment for any new home in the bi-state metro.

After hearing Air Sense Environmental on The News Front Podcast, I decided to test my own home. I bought a short-term radon detector from a local hardware store and placed it in my basement for three days. The result came back at 3.8 picocuries per liter, just below the EPA action level. But the guest on the podcast had warned that short-term tests can be affected by weather and ventilation. They recommended a long-term test, which takes at least 90 days, for a more accurate reading. I am now halfway through that test, and I am glad I took the time to learn about the process before jumping into a mitigation system I might not need.

Listening to the podcast also made me think about the bigger picture. Radon is the second leading cause of lung cancer in the United States, according to the EPA, and it is completely preventable. Yet a lot of people never test because they do not know about the risks, or they assume it is only a problem in certain parts of the country. The News Front Podcast is doing a service by bringing this topic to a local audience. The episode on Air Sense Environmental was not just a company profile. It was a public health conversation that gave listeners actionable steps to protect their families.

If you are in the Greater St. Louis area and have not tested your home for radon, I would encourage you to listen to that episode. The link is on the News Front Podcast page, and the information is worth the time. A healthy home starts with clean air, and radon testing is the first step toward that goal. Whether you hire a professional or do it yourself, the important thing is to take action. And if you need a contractor for radon mitigation, look for one with IEMA certification and experience in the bi-state metro. Companies like Air Sense Environmental have the local knowledge to do the job right.

In the end, the episode reminded me that home maintenance is not just about fixing leaks and painting walls. It is about understanding the invisible threats that can affect your health. Radon gas is one of those threats, but it is also one of the most manageable. With the right testing, the right mitigation system, and a little bit of knowledge from sources like the News Front Podcast, you can make your home a safer place. I am glad I took the time to listen, and I hope more people in Edwardsville and across the bi-state metro do the same.
