  3. Keynote  Time for a Brand New Way Forward for Gas Risk Assessment

    It is 20 years since Wilson and Card was published in Ground Engineering. Remarkably it still underpins the Characteristic Situation approach in BS8485: 2015 + A1: 2019: 2019.

    Geoff and Steve thought it was about time the agenda was moved on and reduced the inherent over conservatism and often unnecessary use of gas protection in the industry. They will present a new approach for ground gas risk assessment, based on worldwide experience and guidance

  7. Receptor Monitoring and Risk Assessment for Ground-Gas

    With the publication of CIRIA C735 there is a much greater focus on the quality of gas protection measure installation and its validation. Where doubts remain regarding the quality of the installed gas protection installation or where validation reports are missing, developers face the risk of having unsaleable properties as planning conditions cannot be discharged. The available options available are limited to:

    A) Demolition and rebuild

    B) Retrofit measures where possible

    C) Receptor Monitoring and Risk Assessment

    This presentation will discuss the context of inadequate gas protection installation and the available techniques and best practice for receptor monitoring and risk assessment. Case studies will be referenced throughout including, high resolution sub-floor void monitoring, internal monitoring and sampling and how these can be used to inform risk management decisions for both new build and existing properties. Examples of common problems and poor workmanship will be provided.

  12. Discriminating Methane Sources in Ground Gas Emissions in NW England

    The identification of the source of methane (CH4) and carbon dioxide (CO2) in gases within unconsolidated deposits outside municipal landfill sites, where there are multiple potential contributing gas inputs, is important for regulation and to inform gas management policy.

  13. Vapour Intrusion, Latest Trends and Practices

    Vapour intrusion is a challenging and rapidly evolving area of land contamination assessment. This presentation aims to provide practitioners with increased confidence in vapour intrusion decision processes and will discuss topics including the following: VI-CSM and key sources of uncertainty; divergence in approach to the  assessment of volatile petroleum hydrocarbons and chlorinated solvents; and latest trends in vapour intrusion pathway assessment.

  17. Removing the Risk - Boo Hole Landfill Site

    Boo Hole a former landfill, determined as statutory contaminated land under Part 2A of  the Environmental Protection Act 1990, made on the basis of the potential significant risk to human health associated with migration of hazardous ground gas towards residential properties located on the eastern and southern boundary of the site. The landfill was historically worked as a sand quarry from circa 1893 for approximately 60 years. The quarry commenced accepting landfill waste from approximately 1971 until the 1990s when the site was closed and landscaped.
