Methane Soil Gas Methane Soil Gas: In geology, methane soil gas refers to the confinement of CH4 within the interstitial pore spaces of subsurface soils. On Earth and potentially on Mars, methane derives from subsurface pockets of biogenic and petrogenic natural gas. To illustrate, accumulations of buried organic matter decay via microbial or thermal degradation….

Hydrogen Sulfide Soil Gas (In Natural Gas) Hydrogen Sulfide: Hydrogen sulfide (H2S) soil gas geologically occurs upon the thermal and microbial decomposition of subsurface organic material deposits. It is typically identifiable in biogenic and petrogenic natural gas sources, along with higher concentrations of methane soil gas. Additionally, nitrogen, oxygen, hydrogen, ethane, and isobutane exist within natural…

What is the Methane Mitigation Process?

ByGeo Forward

What is the Methane Mitigation Process? The methane mitigation process entails eliminating the risk of an explosive event at a building, as a result of hazardous soil vapor intrusion. Vapor intrusion is the natural process by which underground gasses migrate upwards and into buildings. So in the case of structures built atop contaminated soils, the…

Re-Do Methane Testing: Can You Retest Methane Test of Soil?

ByGeo Forward

Can You Retest a Methane Test of Soil? Is it worthwhile to get a retest methane test of soil: Generally Not. Sometimes a methane test will show high results of the hazardous soil gas on a property. And developers will try a retest methane test to get “favorable results.” Regardless, there is a general legal…
