Vapour intrusion research and changes to legislation in the US have resulted in a divergence in approach to the assessment of chlorinated and non-chlorinated (e.g. petroleum) hydrocarbons, driven primarily by potentially high bio-attenuation and typically lower risks associated with petroleum hydrocarbons. Recent legislation changes for chlorinated hydrocarbons has also placed far more emphasis on indoor air quality measurements as part of a multiple lines of evidence approach to vapour intrusion assessment, and a strong litigation culture in the US is driving practitioners towards the collection of high resolution continuous indoor data. Such data can significantly increase the understanding of both human exposure to VOCs and the complex mechanisms for vapour intrusion, thereby aiding the design of effective vapour intrusion mitigation measures. John’s presentation will discuss these drivers and divergence in approach to the assessment of vapour intrusion risks and describe the benefits of high-resolution continuous data, as well as innovative alternative methods and approaches to data collection and improved vapour intrusion assessment.
Regulators, consultants, remediation contractors and other industry experts with a specific focus on ground gas assessment, verification, validation and protection gather to hear the latest industry updates. The conference informs delegates about new research, policy updates and innovative case studies that provide practical insights to current projects. The Q&A sessions, with its panel of expert speakers, offer invaluable networking opportunities. Overall, the conference aims to ensure that delegates leave with the latest knowledge, tools and techniques to address their ground gas challenges.
You can book tickets to the event on the Environment Analyst website. John’s presentation takes place in the afternoon session at 14:40.
