Understanding Ground Gas Risks

Expertise in Ground Gas Risk Assessments

Ground gas risk assessments are crucial for safeguarding properties from hazardous gases that can infiltrate and accumulate in subsurface areas, such as basements, cellars, and other confined spaces. These gases often originate from various sources and can pose serious health and safety risks if not properly managed.

Sources of Ground Gas

Gases can enter the ground from multiple sources and find their way into buildings through cracks, gaps, cavity walls, and other openings. Common sources of ground gas include:

Methane: A flammable gas with potential health and environmental risks. Methane can dissolve in groundwater and is commonly associated with coal mines, worked underground coal seams, and landfill sites. It may also be present on brownfield sites and former agricultural land.
Carbon Dioxide (CO2): Typically found around organic decomposition sites such as landfills. When concentrated in confined spaces, CO2 can displace oxygen, leading to severe health risks, including rapid onset of unconsciousness or death if not detected and addressed.
Radon: A naturally occurring gas produced from the decay of radium. Radon can be found in soil, groundwater, and indoor air, sometimes reaching harmful concentrations. Testing for radon involves prolonged sampling to accurately measure its levels in soil and nearby water sources.

Tellus Geoconsult LTD’s Expertise in Ground Gas Risk Assessments

Tellus Geoconsult LTD has extensive experience in identifying, managing, and mitigating ground gas risks, including those associated with landfills and worked coal seams. Our services include:

Ground Gas Monitoring: We design and implement monitoring regimes to accurately assess ground gas levels and their potential impact on new developments. Our monitoring protocols adhere to current guidance and standards.
Risk Assessment and Management: Using guidelines such as BS 8485:2015 for methane and carbon dioxide protective measures, CIRIA C665/NHBC Guidance for hazardous ground gases, and BS 8576:2013 for investigations, we provide detailed risk assessments. Our approach ensures that gas risks are accurately evaluated and managed without unnecessary over-mitigation.
Interpretation of Gas Data: We critically analyse gas data for anomalies and trends, providing a clear understanding of the gas migration patterns and potential risks. This helps in designing appropriate mitigation strategies and ensuring safe development practices.
