This webinar will be presented by Dr Kim Altinkaynak (Senior Geologist at Aurecon)
A good ground model is fundamental to successful contaminated land assessments. A ground model may take many forms, but it is simply the prediction of subsurface conditions, informed by our understanding of geological processes. We need to understand the ground, and ground-water, conditions to determine how contamination is likely to be present and/or transported. The consequences of a poor ground model may result in a misrepresentation of site contamination conditions, inaccurate exposure scenarios, and overly conservative recommendations. An accurate ground model provides better understanding of contaminant fate and transport, more realistic exposure scenarios and consequently greater confidence in the assessment of human health and ecological risk. In addition, better models reduce the risk of encountering unexpected ground conditions (and contamination), resulting in unforeseen economic, planning, and legal complications. This webinar will discuss methods of developing good ground models and the implications of poor models.
This 60-minute webinar will cover:
- An introduction to ground models [10 minutes]
- Why are ground models important to Contaminated Land Assessments? [10 minutes]
- Examples of bad and good ground models, including some case study examples [15 minutes]
- A discussion on how we can do it better [10 minutes]
- Q & A [15 minutes]
