What is Methane Gas Testing?


What is Methane Gas Testing?

Methane gas testing is the process by which professional geologists and engineers determine the concentration of methane in vapor between soil grains, underground. Typically, this is a requirement by building departments and government agencies. In fact, the tests are mandatory in areas within proximity to oil wells, tar pits and landfills. However, the methane gas testing process can also apply to real estate due diligence investigations. For instance; testing during property transactions. Methane is also colorless and odorless. Thus, it isn’t easily detectable via the human node factor. Nonetheless, it posses a great danger for explosion when accumulating inside underground parking garages, basements and buildings above ground. Updated June 19, 2019.

What is Soil-Gas?

Soil-gas is the vapor phase substance that exists within the pore spaces of soil grains underground. In scenarios where liquid phase toxins are dumped into the ground, chemicals migrate into the soil to great depths. Consequently, the liquid phase contamination can change phases, into vapors. And as a result, the vapor phase contamination can migrate even farther. The true danger about vapor phase migration is it’s ability to creep through building foundations and microscopic pathways in concrete walls. For example, a restaurant existing above a former oil well can be infiltrated with natural gas, along with other carcinogens, posing a health and combustion risk to the occupants inside.

Health & Safety

Carcinogen health risks tend to base on long-term exposure rates. However, are still material to the health, safety and well being of people. Similarly, combustion hazardous occur by the over-concentration of this flammable gas indoors. Any ignition source inside a room with methane gas above the “Lower Explosive Limit” or “LEL” can result in an explosion. These catastrophes have happened before. Thus, awareness and implementation of soil-gas testing and mitigation is a requirement in jurisdictions across the nation.

Methane Testing initially includes a shallow probe soil gas survey. Afterwards, a drilling rig is used to drill and install multiple sampling zones underground.
