Business Owners in Greenville, South Carolina Need to be Aware of Vapor Intrusion

Vapor Intrusion GreenvilleNo matter where your commercial building is located in the United States, the possibility of ground contamination seeping into your home exists. In some cases, radon gas is the only culprit, but in many other instances, a number of additional volatile chemicals can intrude the air space within your building. When this occurs, it is known as vapor intrusion.

Generally, this type of vapor intrusion results as one or more potentially dangerous chemicals seep up from beneath the building and enter its air supply. The vapors can come from pollutants that have contaminated either the ground or the ground water. If the vapors remain trapped in your building, they pose a serious health risk for anyone working within the building and strategies must be taken to remove them.

The Dangers of Vapor Intrusion in Greenville, South Carolina

Vapor Intrusion (VI) is a serious health threat that can become complicated when high levels of contaminants are involved or when additional emission sources exist within your commercial building. Solvents, gasoline, and cleaners that are used within the building can all pose significant health risks even without the presence of vapor intrusion. Immediate risk of vapor intrusion includes: acute health issues and explosions if the buildup is severe enough or a combination of volatile chemicals is present.

The presence of odors can also occur. Odors are good indicators that something is amiss, warning you that your indoor air may be contaminated. While low levels of certain contaminants may not pose an immediate health risk, exposure over long periods of time are more likely to lead to serious health issues.

There Are Many Ways Vapor Intrusion Can Happen

Any one of a number of contaminants can be involved when vapor intrusion occurs. They include: radon gas, trichloroethylene (TCE), perchloroethylene (PCE or PERC), tetrachloroethylene (dry cleaning fluid), volatile organic compounds (VOCs), gasoline ground contamination (Petroleum Hydrocarbons), natural gas, methane, and a variety of other solvents and gases. Some of these chemicals come from solvents used to clean metal parts, dry cleaning solvents, and carbon based chemicals, while others come directly from natural gas sources. None of them are good for humans to breathe. Therefore, mitigation strategies are necessary.

The most effective treatment in preventing dangerous ground contamination to pass from the soil to the air supply of a building is Active Soil Depressurization (ASD). Commonly used by radon mitigation specialists to treat radon contamination, ASD is quite effective in mitigating the potential risk of vapor intrusion. . This process equalizes the pressure between the interior of the building and the ground beneath it, eliminating the presence of the poisonous gases that have infiltrated your commercial building. Whether your commercial building is only suffering from radon contamination or it is actively experiencing vapor intrusion from several contaminants, radon mitigation specialists can eliminate this danger using ASD.
