Living in the beautiful state of Colorado comes with many perks – fresh mountain air, stunning landscapes, and endless outdoor activities to name a few. However, there is one potential downside to watch out for – exposure to radioactive radon gas. While radon occurs naturally in soil and rock, it can seep into homes and build up to dangerous levels. According to the EPA, radon is the second leading cause of lung cancer in the United States. Fortunately, with proper testing and mitigation, radon exposure can be avoided.
For Colorado homeowners, radon testing is absolutely essential to protect health and safety. Here are five compelling reasons radon testing in Colorado should be a top priority:
1. Colorado Has High Radon Potential
Unlike some naturally occurring hazards, radon potential is not evenly distributed across the country. Certain states, like Colorado, have geologies and soil types that can more easily facilitate radon seepage and buildup. According to the U.S. EPA, seven Colorado counties are currently ranked in Zone 1 – the highest potential radon zone. This means indoor radon levels are expected to exceed the EPA action level of 4 pCi/L.
The only way to know if your home’s radon level is above the recommended threshold is to test. Living in Colorado means radon exposure risk is higher, making testing even more vital.
2. Radon is Odorless and Invisible
Unlike smoke or carbon monoxide, radon produces no obvious sensory cues to indicate a problem. You cannot see it, smell it, or taste it. The radioactive gas is naturally colorless and odorless. The only way to detect its presence is through specialized radon testing devices.
Without testing, radon exposure can go unnoticed even as damage to lung tissue slowly occurs. Testing is the only way to become aware of a radon problem before health consequences emerge.
3. Radon Can Build Up Quickly
Radon levels fluctuate day to day based on soil conditions, weather, and other factors. Long term radon reduction requires mitigation systems to constantly counteract seepage and accumulation. However, radon buildup can also spike over short periods of time.
For example, weather or construction projects disturbing the soil around a home’s foundation could facilitate a rapid influx of radon gas. The only way to detect these temporary surges is vigilant testing at different times throughout the year.
4. Radon Mitigation Systems are Effective
The good news about radon is that when identified, it can be effectively managed. Radon mitigation systems work by redirecting soil gas away from the home’s interior breathing space. Fans maintain constant negative pressure to ventilate radon from below the foundation before it can enter the home.
Once installed, these passive systems provide constant protection. But mitigation can only be implemented if testing first detects a high radon level. Without testing, this preventative measure would never be taken.
5. Radon Testing is Easy and Affordable
Given the serious health risks, the case for comprehensive radon testing is clear. The good news is that testing your home is easy and affordable. Home radon test kits utilize air sampling devices that are left in place for a set duration before being mailed to a lab for analysis.
Online stores provide test kits for as little as $15 to $30 per device. Contracting with radon testing professionals offers precise result reporting. With such simple and low-cost options, radon testing is a small investment that can yield huge dividends in risk reduction.
In summary, radon testing provides vital health and safety information to Colorado homeowners. It is the only way to detect the presence of the harmful gas, enabling mitigation before lung damage can occur. Given the ease, affordability, and benefits of testing, there are simply no good reasons for Colorado residents to avoid this basic precaution.
Why is Radon gas so prevalent in Colorado?
Colorado’s geology and environmental factors contribute to higher levels of radon compared to other parts of the country. Here’s a closer look at why radon is so common in the state:
Uranium-rich soil
Parts of Colorado, including areas along the Front Range, have soil with higher concentrations of uranium. As uranium naturally decays, it produces radon gas which can move up through the soil. Homes built in areas with uranium-rich soil have a higher risk of radon seepage.
Rocky soils
Rocky, gravelly soil also facilitates the movement and release of radon gas from underground up to the surface. This soil type allows radon to flow more freely compared to densely packed clay soils that impede gas transport.
Cave systems
Natural cave and tunnel systems found in parts of Colorado provide pathways for radon to move up and accumulate, especially if a home is built above these underground spaces. Fractured bedrock also acts as a transport mechanism.
Mine shafts
Old abandoned mine shafts and tunnels dotted throughout the Colorado mountains can concentrate and discharge radon gas, exposing nearby homes and properties. Colorado has hundreds of historic mining sites that boost radon potential.
Weather and climate
Extreme weather like heavy snow or rainfall can drive radon up from the soil. Cold winters also exacerbate radon accumulation indoors as homes seal up tight. The right climate conditions motivate radon entry and buildup.
With the perfect storm of soil, geology, mines, and weather, areas of Colorado have among the highest radon potentials in the U.S. Testing is vital to identify and mitigate this risk. Proactive radon monitoring should be part of every Colorado home’s safety routine.
Which areas of Colorado have the biggest radon risks?
While radon occurrence is unpredictable, there are parts of Colorado known to have higher radon potential based on testing statistics, geology, and other factors. Homeowners in these higher-risk areas should be extra vigilant about testing and mitigation. Some radon hot spots in Colorado include:
Front Range region
The Front Range area that includes metro regions like Colorado Springs and Denver presents some of the highest radon risks in the state, with many counties falling into the EPA’s most severe Zone 1 hazard rating. Homes in this area should test frequently.
Western Slope and mountain areas
West of the Continental Divide, popular ski and mountain town counties like Eagle, Pitkin, and Gunnison have elevated radon levels. The uranium-rich soil and extensive old mines contribute to radon in the Western Slope.
Northern Colorado
Weld County and surrounding northern Colorado areas display especially high radon concentrations that can enter homes built above gravel and fractured bedrock. Careful testing is a must in this radon-prone region.
Uranium mining areas
Areas with past or current uranium mining operations like parts of Mesa and Montrose counties have reported extremely high radon levels far exceeding EPA recommendations. Homes near these sites need vigilant monitoring.
Homes near old mines
Any private home, cabin, or property built near Colorado’s historic mining operations risks radon seepage from old shafts and tunnels. Testing is the only way to detect radon from abandoned mines.
While radon potentials exist statewide, these areas have demonstrated particularly acute radon hazards. All Colorado residents should test regularly, but homeowners in high-risk regions should be especially dedicated to monitoring and mitigation. Consulting local radon zone maps can help determine your area’s radon history and recommend testing frequency.
How can Colorado homeowners test effectively for radon?
Conscientious radon testing is the only way for Colorado homeowners to understand their property’s radon status. Here are some tips for the most effective testing protocol:
- Use certified long-term test kits – The most definitive tests use alpha track detectors left in place for 90 days to get a full picture of possible radon spikes. Look for devices approved by national certification organizations.
- Follow proper protocols – Carefully follow all instructions for ideal placement and appropriate test duration. Errors could compromise results.
- Test on lowest livable levels – Radon concentrations are highest in basements and ground floor spaces. Place detectors there.
- Perform initial short-term screening – Do a faster 2-7 day test first before a long-term reading to get a general idea of radon present.
- Test in different seasons – Re-test your home during different weather that affects radon levels like summer vs. winter.
- Test after major renovations – Retest following any remodels disturbing soil or foundations that may shift radon entry routes.
- Hire a professional – Consider contracting certified radon professionals for the most precise and hassle-free testing.
With strategic radon monitoring using reliable devices, Colorado homeowners can keep close tabs on radon without overspending. Consistent testing is the only way to detect changes in radon levels and confirm your home’s safety.
What prevention measures can reduce radon risks in Colorado?
Once radon testing reveals a high level in the home, there are several effective mitigation methods Colorado residents can employ:
Install a radon reduction system
This is the most definitive action once radon is detected. A certified radon mitigation contractor can design and activate a sub-slab depressurization system. This funnels radon from beneath concrete floors to outside air.
Seal cracks and openings
Any cracks or openings in a home’s concrete foundation should be caulked or sealed to reduce possible radon entry routes. Ensuring a tight barrier keeps soil gas out.
Increase basement and crawlspace ventilation
Improving air circulation removes radon gas and dilutes concentrations. This could include installing vent fans, adding vents and louvers, or creating open-air sump pits.
Cover exposed dirt floors
In crawlspaces or basements with exposed dirt floors, covering the ground with heavy plastic sheeting can form an air-tight radon barrier. Seal edges with tape.
Alter landscaping and drainage
Sloped soil, drainage pipes, gutters, and proper landscape grading near a home’s foundation moves moisture away to lessen soil gas movement.
With the right mitigation approach, dangerous radon accumulation can be minimized. But altering a home’s radon status requires first identifying high levels through careful long-term testing. Detecting and addressing radon is a prudent investment in health.
How much does radon mitigation cost for the average Colorado home?
Once testing reveals a radon hazard, the next step is implementing mitigation to actively ventilate radon from beneath a home. On average, radon mitigation costs for a typical single-family Colorado home range from:
- $800 to $2,500 for simple active soil depressurization. This involves adding PVC vent pipes and an in-line fan.
- $2,500 to $3,500 for more complex sub-slab depressurization requiring elaborate venting networks and multiple suction points.
- $3,500 to $7,000 if drain tiles or major foundation sealing must be installed along with the ventilation system.
Mitigation costs depend on several factors:
- House size – More ventilation piping is needed for larger spaces.
- Foundation type and access – Ease of installing beneath floors impacts cost.
- Radon level – Higher concentrations require increased fan capacity and ventilation.
- Existing home systems – Integrating with HVAC and avoiding plumbing and wiring ups cost.
- Geographic location – Labor and material costs vary regionally.
With the right certified radon contractor, even extensive mitigation is a worthwhile investment compared to the expense of lung cancer treatment. Most homeowners find radon reduction systems quickly pay for themselves in added health and resale value.
Does homeowner’s insurance cover radon mitigation?
Unfortunately, the costs of installing a radon mitigation system, which average $800 to $3000, are generally not covered by homeowners insurance policies. There are several reasons why radon remediation is excluded:
- Pre-existing condition – If high radon levels already exist at the time of policy enactment, insurance will not cover mitigation.
- Not sudden or accidental – Radon accumulation is gradual over time, not sudden property damage.
- Preventative measure – Mitigation prevents future exposure and illness but is not in response to an active covered loss.
- Not legally mandated – Radon reduction is advisable but in most cases not legally required, leaving it optional for policyholders.
- Available as a separate policy – Radon-specific remediation policies can be purchased for coverage instead of filing under homeowners insurance.
While the health benefits clearly warrant the investment, the cost of installing a radon mitigation system falls upon the homeowner in most cases. This provides all the more incentive for diligent radon testing to detect high levels early before mitigation becomes urgent. Discussing options with your insurance agent is advised.
