Waterborne Radon and the North Carolina Radon Program

Radon in Water Charlotte, North CarolinaAccording to the Center for Disease Control, radon contamination is estimated to cause thousands of deaths each year. The waterborne radon problem in North Carolina may not be as deadly as in the hardest-hit states, but it is still a significant enough problem that residents should educate themselves about the dangers of radon in water and how to protect themselves from it.

The North Carolina Radon Program was founded to educate residents about the dangers radon poses and how to protect themselves. The program’s goal is to have homes built with radon-resistant construction techniques and to have information on testing and mitigation revealed to homeowners during the transfer of real estate. They also want to see schools tested for radon — a process that homeowners should have performed regularly in their own homes. The program is currently setting environmental goals and developing grass-roots coalitions to spread awareness about radon risk and reduction methods. Citizens can contact them with any questions or concerns they may have about either airborne or radon in water.

The Dangers of Radon in Water

The danger of radon in drinking water begins when water from an underground source such as a well becomes contaminated — which can happen easily since radon is naturally created underground. Radon gas contaminated water can cause lung cancer in humans when the radon particles escape into the air. These particles can severely damage the lung’s tissue over time after they are inhaled. Drinking radon-contaminated water can also damage other internal organs such as the stomach, potentially even causing stomach cancer. However, the most severe health problems tend to arise from inhaling the radon after it escapes from the water.

Techniques to Mitigate Waterborne Radon

If testing finds that your home’s water is contaminated with radon, you will need to have SWAT Environmental purify it. Aeration and absorption are the two main techniques used to remove radon from a water supply. Aeration methods such as Packed Tower Aeration mitigate radon from large flows of water by trapping it in water bubbles. The raw water is sprayed into a tower until it trickles down onto plastic packing. Air is then pumped into the packing to enhance the radon’s removal so it can be channeled into a reservoir tower below. Lastly, the air containing the radon gas is released from the top tower, preventing it from entering your home.

Another aeration method, Diffused Bubble Aeration, mitigates the radon gas by injecting air into the water. The radon gas becomes trapped in the bubbles as they rise. The gas is then vented out of the system when it reaches the top unit. Cascade Aeration is the simplest method of removing radon from water. It uses a series of steps similar to a waterfall for the water to flow over. Ventilation then removes the gas from the unit.

Absorption is the other primary method used to remove radon in water. This technique uses granular activated carbon to absorb the radon gases. The carbon becomes saturated with the radon over a period of time, cleansing the water of the contaminant. To ensure continuous decontamination of water, the carbon must be replaced or regenerated by steam cleaning periodically. In some cases, multiple systems will be necessary to complete remove the radon from your home’s water supply.

Is Your Charlotte, North Carolina Home Safe From Radon? It’s Radon Action Month

Radon Action Month CharlotteDesignated by the Environmental Protection Agency (EPA) as National Radon Action Month, January presents the perfect opportunity for Charlotte residents to arrange to have their homes tested for the presence of radon. If you think about how much time you actually spend indoors during this time of year, then you will realize the importance of having your Charlotte home tested now rather than later.

An odorless, tasteless, and colorless gas, radon is considered the second leading cause of lung cancer in residents of the United States. In fact, it is the leading cause of lung cancer for non-smokers. Radon forms beneath the earth’s surface when uranium begins to decompose. As this radioactive gas builds up in volume, it searches for a way out and typically, ends up in the homes located in Charlotte and other areas of the country.

How does radon get into your home? As this radioactive gas tries to escape from its confinement in the ground, it follows along fissures in the ground until it reaches the surface. In some cases, this noxious gas escapes into the earth’s atmosphere and in other instances, it ends up in the homes located in Charlotte.

What Charlotte Area Residents Need to Know about Radon

The EPA has determined exactly what levels of radon they consider to be unsafe for human exposure. Levels above 4.0 pci/L are designated as dangerous, and radon mitigation strategies are recommended in order to remove this poison from the home. If you live in the Charlotte area, then your home is at risk of having radon contamination no matter how old the home is. Homes with and without basements or attics are equally at risk.

More than 20,000 people are estimated to die each year due to radon-caused lung cancer. The threat is real. Charlotte area residents are urged to have their homes tested during National Radon Action Month in order to discover whether or not their homes are contaminated by this radioactive carcinogenic gas.

It’s important to realize that radon levels vary throughout the year, so testing should take place at least once every couple of years.

Charlotte North Carolina is at Risk of Radon and Vapor Intrusion

Vapor Intrusion CharlotteAre you aware that Charlotte, North Carolina is one of the hot spots for radon and vapor intrusion? It’s more likely that your home is contaminated with a radioactive gas known as radon if you live in this area. Arrange to have your home tested for vapor intrusion, and then if need be follow up with radon mitigation procedures if necessary.

Radon is formed as uranium breaks down beneath the earth’s surface. It builds up continually, searching for a way to escape the confines of the earth. It filters through the cracks and fissures that have formed in the ground until it reaches a point of escape. In some cases, this gas may be able to escape directly into the atmosphere where it quickly diffuses. In other cases, it enters the homes located in Charlotte, North Carolina and contaminates interior air with poisonous, deadly fumes that can cause lung cancer. This is vapor intrusion at its worst. In fact, since the atmospheric differences between a building and the ground is so great, it is almost as though your home is sucking that deadly gas through the foundation cracks, ground-level windows, and holes in the building walls.

Charlotte, North Carolina Homes and the Risk of Radon

Radon Risk Charlotte North CarolinaMost Charlotte, North Carolina homeowners are aware that radon gases present in the home pose dangers to the health of both children and adults and take steps to mitigate these hazards. For example, carbon monoxide detectors are often installed in a residence to prevent carbon monoxide poisoning. Less well-known is the serious health risk posed by high levels of indoor radon. The U.S. Surgeon General issued a statement in 2009 that over 20,000 Americans die each year of lung cancer directly or indirectly caused by breathing radon-polluted air. As a matter of fact, radon is the number one cause of lung cancer in people who don’t smoke, and the second leading cause in people who do smoke.

What is Radon and How it Can Harm You

Radon is a naturally-occurring gas anywhere radium and uranium are present. This odorless, colorless, tasteless emission results from the decay of radium and uranium, seeping up through the ground to penetrate the air. Dispersed into outdoor air, levels are low and not harmful to human health, but when radon is confined under a house, it can infiltrate indoor air in quantities concentrated enough to cause lung damage. Because radon is undetectable by human senses, the only way to determine your home’s radon level is to perform a radon detection test.

What Can You Do to Prevent Radon From Harming Your and Your Family?

Radon detection can be accomplished by either purchasing a test kit from a hardware, home improvement, or grocery store or by consulting a radon mitigation specialist in your area. DIY test kits are generally priced at under $25 and are usually mailed to radon detection labs that read the results and inform you of your level of radon detection. A radon reduction professional can perform the test for you and inspect your home for potential radon entry points. In either case, the Environmental Protection Agency recommends immediate action if your home tests for levels higher than 4 picocuries per liter (pCi/L), a measurement of radioactivity. Many health experts urge homeowners to seek radon mitigation even when levels are between 2 and 4 pCi/L, since even a low level carries risk for respiratory health.

Due to Charlotte, North Carolina’s specific geology, the risk for radon in any particular home is significant. The eight counties deemed highest in risk for radon are Alleghany, Buncombe, Cherokee, Henderson, Mitchell, Rockingham, Transylvania, and Watauga, but substantial levels of radon have been detected in almost every county in North Carolina. Because indoor radon is not caused merely by the presence of uranium in the underlying geology of an area, you can’t rely on tests performed by your neighbors. Your particular structure may be more or less vulnerable to radon emissions.
