ALGA’s Queensland Branch presents a forum on Developments in Site Characterisation and Assessment Methodologies.
1. High Resolution Site Characterisation Technologies – David Heicher, HRVP Division Manager, Numac Drilling Services Australia.
To expedite site investigation activities, increase the quality and quantity of data collected, and develop a more comprehensive conceptual site model, innovative High Resolution Vertical Profiling (HRVP) technologies (also known as Direct Sensing) have been utilized at contaminated sites over the past 15 years. These systems are designed to collect data in real-time and high definition (65 readings per vertical metre) continuously throughout the subsurface vertical profile. Semi-quantitative data is collected, recorded, and subsequently incorporated into modelling software to generate real-time, 2D-3D graphics revealing plume geometry as an investigation is taking place. David will share some of his knowledge on these techniques and present a Queensland example.
2. Summary of Vapour Intrusion Presentations and Workshops from the recent International AEHS Conference – Bill Stavropoulos, Environmental Services –Technical Manager, SGS Leeder Consulting
The “24th Annual International Conference on Soil, Water, Energy and Air” was recently held in San Diego, California. The conference has a very significant Vapour Intrusion focus and is strongly supported by the US EPA. Bill’s presentation will aim to provide an overview of the presentations and workshops with the aim of highlighting current topics of interest and discussions related to Vapour Intrusion.
3. Odour Measurement in the Field – Andrew Balch, Director, Air Environment Consulting
Environmental regulators and local government authorities have reported that two-thirds of the community’s environmentally-related complaints are concerned with odour nuisance. Sources that are common causes of odour complaints include waste and wastewater handling and treatment processes, contaminated land remediation, heavy industry and manufacturing processes. Until now, odour assessment has typically followed a source sampling, laboratory testing and atmospheric dispersion modelling approach to assess potential community impact. Odour concentration measurement at the source or downwind in the community has not been feasible due to method limitations and instrument insensitivity. A new instrument, known as a Field Olfactometer, has the potential to change the approach to odour measurement, or at the very least, dramatically improve and compliment current methods. The Field Olfactometer is designed to measure odour concentration at the source, from a sample bag or in the plume downwind of the source. It is suitable for boundary and receptor ambient odour assessments when managing odorous activities and assessing their impact.
Andrew will briefly discuss odour measurement and demonstrate the Field Olfactometer.
