Soil Gases

Besides Radon, there are other gases and contaminants that can be released from the soil that can also pose a danger. Whether it’s radon, methane, benzene, toluene, ethylbenzene, and xylenes (BTEX), trichloroethylene, or other contaminants, Midwest Radon Services is here to help.

BTEX is an acronym that stands for benzene, toluene, ethylbenzene, and xylenes. These compounds are some of the volatile organic compounds (VOCs) found in petroleum derivatives such as petrol (gasoline). Toluene, ethylbenzene, and xylenes have harmful effects on the central nervous system.

BTEX compounds are notorious due to the contamination of soil and groundwater with these compounds. Contamination typically occurs near petroleum and natural gas production sites, petrol stations, and other areas with underground storage tanks (USTs) or above-ground storage tanks (ASTs), containing gasoline or other petroleum-related products.

The amount of 'Total BTEX', the sum of the concentrations of each of the constituents of BTEX, is sometimes used to aid in assessing the relative risk or seriousness at contaminated locations and the need of remediation of such sites. Naphthalene may also be included in Total BTEX analysis yielding results referred to as BTEXN. In the same way, styrene is sometimes added, making it BTEXS.


Trichloroethylene (TCE) is a chlorinated hydrocarbon commonly used as an industrial solvent. It is a clear non-flammable liquid with a sweet smell. It should not be confused with the similar 1,1,1-trichloroethane, which is commonly known as chlorothene.

It has also been used as a dry cleaning solvent, although replaced in the 1950s by tetrachloroethylene (also known as perchloroethylene), except for spot cleaning where it was used until the year 2000.

Perhaps the greatest use of TCE has been as a degreaser for metal parts. The demand for TCE as a degreaser began to decline in the 1950s in favor of the less toxic 1,1,1-trichloroethane. However, 1,1,1-trichloroethane production has been phased out in most of the world under the terms of the Montreal Protocol, and as a result trichloroethylene has experienced some resurgence in use as a degreaser.
