Passive soil vapour measurement technology | Gary Hirst, Dr Brent Davey & Richard Campbell
Presenters:
When it comes to passive soil vapour measurement, Dr Brent Davey, Gary Hirst and Richard Campbell are three of the best in the business. HydroTerra bought together these experts to demystify the complexities around the current and correct technologies to use, the techniques that provide the most meaningful and accurate data and how best to use that data for informed decision making.
Principal Environmental Consultant, Dr Brent Davey from Fyfe will provide an overview of soil gas and vapour intrusion sampling technologies with a focus on ‘in field’ options for measuring soil gas and vapour intrusion.
His presentation will include:
- Sampling ambient air, indoor spaces, under slabs and bores/wells – available hardware, buy, hire or DIY
- Traditional ‘active’ methods such as air sampling pumps through absorbents
- Pros and cons of Summa® cannisters, diffusion samplers such as Radiello, Waterloo and Beacon (including which to use when, and what to ask your lab for)
Richard Campbell, in partnership with SLR Consulting’s Technical Director – Land Quality & Remediation, Gary Hirst, presented the following:
- Challenges of traditional techniques in characterising NAPL source zones
- The value of passive soil gas sampling and relevance of data collected
- Advantages and installation of passive samplers
- Laboratory analysis methods for passive samplers
- How results help make informed decisions for volatile sources
- Case studies outlining different applications
