Ground gas - sampling and assessment techniques

Supported by Envirolink Northwest

24 September 2008, Penrith

The problem

Many professionals have difficulty assessing the significance of elevated ground gas results, especially where it is being generated from sources such as peat, petrol contamination or made ground. There is also a lack of understanding of the additional data that needs to be considered when interpreting gas monitoring results.

A solution

By the end of the course delegates should understand the data that is required to interpret gas monitoring results. They should be able to determine the gas screening value for a site and make a pragmatic assessment of the risk posed by the presence of ground gas on or adjacent to development sites.

Topics covered

• Relevance of different parts of the data (eg flow measurement)
• Using the assessment methods in CIRIA C665 and BS 8485
• How to determine if gas monitoring data is sufficient
• Other data that is needed to interpret gas monitoring results
• Practical examples of interpreting data from different sources (interactive group work)
• Other gases and vapours.

Who should attend

• Local authority contaminated land officers, planners, environmental health officers
• Consulting engineers and environmental consultants
• Contractors
• Developers
• Landowners
• House builders
• Regulators
• Researchers and academics.

Required level of knowledge

Prior knowledge of the chemistry of landfill gas generation and gas monitoring methods will be
required. This is not a course for anyone without some prior knowledge.
